We did continue to supply the fhermlnol PR series heat transfer fluids Into existing systems as makeup where we were assured that its use was in a non-food related system. In a continuing effort to prevent any PCB from entering the en vironment, last December we notified our CLS. customara^that the sale of all FCB-containlng Therralnols, namely Thermino3? JR LoTemp, PR-0 and PR-1, was being discontinued. We are currently extending discontinuation world-wide. We are suggesting that these remaining systems be drained completely, flushed to remove PCB, and refilled with non-PcB fluids. The roost likely Monsanto candidates would be Therrainoi 5$ and Therminol 66, We are also asking that all PC materials be returned to us for disposal. In most oases this conversion can be accomplished with very little change to the system. It is important, however, to realize that the new fluids are not fire resistant and that protective devices may be necessary for these fluids just the same as for other com bustible fluids, Suggestions regarding fire protection and other conversion details are included in the attached "Therroinol Conver sion" bulletin. We hope this will be helpful to you in answering any questions you receive as co-suppliers In Therminol PR systems. We again want to ask your cooperation in this period of system con versions and appreciate your continued use and recommendation of the non-FCB containing Thermlnols, namely 55, 66, 77 and 88.

Lindbergh Blvd., St. Louis, Mo. 63186 MCL002071 `1 INTRODUCTION Therminol FR fire-resistant heat transfer fluids have long provided safe, dependable, economical performance for hundreds of users in dozens of applications. The presence of poly-chlorinated biphenyl (FCB) in the Therminol FR forinuifttion provided fire-reewtance, giving Therminol FR an added margin of safety which was especially desirable in hazardous applications. Most recently, FCB has been identified as a potential hazard to the environment. Monsanto has accordingly elected to discontinue the manufacture and sale of Therminol FR fluids for heat transfer appli cations.-This bulletin is to inform you about two alternative products sold by Monsanto which do not contain PCB, namely Therminol 55 and Therminol 66. These product* offer most of the excellent heat transfer characteristics of Therminol FR fluids, and even a few additional advantages, such as a lower specific gravity for improved pumpability requiring less horsepower. "We would point out that Thsroinol 55 and 66 are not fire-rmstant to the extent the Therminol FR fluids were, and due consideration must be given this fact in converting to these newer Therminol fluids. Tou may wish to consult with your insurers on any conversion from Therminol FR. Conversion from a Therminol FR fluid to a Therminol 55 or 66 fluid will be a relatively siroplq, low-cost procedure in the majority of cases. Incorporation of proper fire protection equipment will be the only consideration of major consequence in most cases. But even this modification becomes academic, for with the discontinuation of Thertnittoi FR fluids, fire protection equipment becomes necessary for any and all low pressure heat transfer media available today, since the Therminol FR fluids were unique in their fire-resistance. Should question* arise with respect to the conversion from Therminol FR fluid, Monsanto's Specialty Products Group invites you to call upon its staff or qualified systems engineers for consultation at any time. Call... (314) 694-2514 and ask for a Monsanto Heat Transfer Specialist.

As you wOl note, Therrainol 55 and 66 are quite similar except with regard to AIT, Fire Point and density. The substantially lower density of Therrainol 55 and 66 means that pumps used in a Thenninol FR-1 system should be adequate for a Therrainol 55 and 66 system. In most cases, pumping rates will be increased with a resultant saving in horsepower require ments.

Itimportant to realize that Thermlnol 55 and 66 are less fire-resistant than Therrainol FR-1, and to modify theheat transfer systen aeeordingiy; it is equally important to understand that Thermlnol 55 and 66 are not volatile, highly flammable fluids, but rather combustible as defined by FM and NFPA (NFPA No. 821). There are two major fire protection considerations in changing to . Thermlnoi .55 or 66 -- system leakage and possible tube ruptwe (In the heater). The former is actually part of the larger subject of good system maintenance, and should be considered regardless of the heat transfer medium employed. A tight, well-maintained system is usually a good, safe system! Following arc some suggestions to prevent leakage when you convert to Therminol 55 or 66. First, if your system has rotary mechanical seals, you should provide a spray shield and a drip pan with a drain to a collection sump. Canned and seal-less pumps offer excellent protection against leakage. The best way to prevent piping leakage is to weld all connections. Where you must have access, use raised-face flanges with appropriate gasketing and high-temperature bolting. Control iff piping leaks is especially important, since fluid-soaked insulation poses a more serious hazard than the leaking fluid, itself. Organic compounds such as Therminol 55 and 66 exhibit a slow oxidation reaction with the ah* trapped inside the voids of the in sulating material when system temperatures reach about 5QOF. Saturated insulation offers a large fuel surface in the face of poor heat dissipation conditions, and this, along with possible catalysis from the insulating material (magnesia, silicate-bonded asbestos or calcium silicate) can cause a temperature build-up in the mass. This temperature build-up can result in ignition of the fluid when the apace between the piping and the saturated insulation is exposed to air (Le., should the insulation be broken for repair, etc.). This phenomenon is not fully understood, but appears to occur less with closed cell insulation than with the insulating materials mentioned 7 MCL002077 above. dosed cell materials, then, ore preferred, especially where leakage k a possibility despite all precautions. The principle problem areas are near instrument connections, valve paefeingg&ada, flanges, and where cracks develop, in relatively im permeable insulation cement adjacent to oil soaked insulation. To obviate tbs problem, eliminate any source of leakage promptly. Replace leaky gaskets, oil soaked insulation, and re-pack valve stems. Cover insolation where leak* might occur with a hydraulic setting, oH-reaatant cement Install valves, where possible, with the stems in a horizontal position so that leaks will drip away from the insulation. And again, use closed cell insulating materials on suspect piping areas. Tube Rupture in Fired Heaters Generally speaking, where fire protection is concerned, it is beat to consult-your insurance underwriter for guidance and counsel. likewise, you will want to discuss your fire safety equipment requirements with qualified suppliers of fire protection equipment. Selection and sizing of fire protection equipment is important to safeguard the installation. A commonly used method of preventing fire in the event of tube rupture in fired heaters is piping steam or CO* as a snuffer into the combustion chamber of the heater. Usually a properly-sized line with a remote manual valve for activation is the preferred arrangement. This snuffer system could be automated by the use of an exhaust stack temperature switch. This switch would then energize a solenoid valve and alarm upon excessive temperature rise, automatically Hooding the chamber with a fire extinguishing agent. In practice the temperature switch is often set about lOOT. am tbe normal exhaust temperature to prevent nuisance shutdowns. Where steam snuffer systems are used, it is a good idea to employ a steam trap to avoid slugging the combustion chamber with water when the system activates, or is activated manually. You can obtain a basic guideline in the selection of CO, protection equipment (again, it is best to consult your insurance underwriter) from the National Fire Protection Assn., 60 Batterymarch Street, Boston, Mass. 02110 AC 617-482-8755. NFPA Bulletin No. 12 dated 1968 should be requested. This bulletin should be helpful in determining the amount of CO, and the concentration of CO, needed to extinguish a fire based on your specific application. CO* cylinders are available from Cardox Division of Cberoetron, Chicago, HI. as well as other suppliers. Some standard sizes are 50. 75, 100 and 150 pound cylinders. Prices usually include drawings of the units, fully charged cylinders, flexible piping connectors, spray nozzle, pressure switch, alarm and automatic control, provided COt release signal is supplied by customer device. Piping, wiring, and installa tion labor to be provided by the customer. Recharging of spent cylinders is available at an additional coat from a variety iff "Fire & Safety Equipment Suppliers" listed in the Yellow Pages of your phone book. $ MCL002078 '5 f- jj \S Selection of all equipment and in*tall&tion rOcomtuendatioas should be obtained from qualified suppliers; however, it is important to insure that sufficient CO is available to prevent re-ignition while the heater is cooling. The Halon Fire Suppression System is a possible alternative to a CO* arrangement because it can be used, in closed spaces with personnel in the area. One supplier of Halon systems is the Cardox Division of Chemetron Corporation, Chicago, IB. 60611. Again, m strongly recommend that the advice of fire protection companies be solicited in either case to insure proper equipment selection and installation. If steam is to be used rather than the other alternatives suggested above, please refer to the NFPA Volume I, Section 86A (1970-1971) to obtain the volume of steam required. Oxidation-Resistance With a Therminol 55 or 66 system, some provision should be made to prevent oxidation caused by air contact at fluid temperatures exceeding 200*F. This was not the case with Therminoi FR fluids, but must be observed for Therminol 55 and Therminol 66. Oxidation can result in sludge formation, eventually leading to carbonaceous deposits on beat transfer surfaces and at mechanical seal faces. Oxidation of fluid can develop by air contact in an open, vented expan sion tank. Therefore, we recommended that the expansion tank be blanketed with an inert gas (such as nitrogen) as shown in Figure 4. If this is not possible, air contact can be minimized by a cold sea! arrange ment as shown in Figure 5. An inert gas pressure of one to two psi is adequate, as Therminol 65 and 66 do not require pressurization to maintain liquid phase. FIGURE 4 SUGGESTED INERT GAS ARRANGEMENT FOR EXPANSION TANK You can design the cold seal arrangement quite simply by piping the expansion tank vent to a second tank where the vent line projects subsurface and can be flooded with additional Therramol 55 or 66 to minimize air contact in the expansion tank vapor space. In converting from Therminol PR to Therminol 66 or 66, it is important to remember that many Therminol PR systems were designed with a hot Meed line into the expansion tank to eliminate moisture accumula tion. Moisture accumulation in the presence of hydrogen chloride gas released during the decomposition of the FR fluids could contribute to acidity problems. This not the case with Therminol 55 or 68; there* ftore, this bleed line should not be need during normal operation of a Therminol 55 or 65 $ytUrm, This line should be mlvtd of during opera tion hut it could be retained as a convenient means of venting the system during initial startup after conversion. Further protection against a hot expansion tank occurrence would be the removal of any expansion tank insulation and feeder line insulation. Carbonaceous deposits can also occur at the pump seal face due to leakage at high temperatures. The use of a seal flush system or a double mechanical seal is helpful in preventing excessive seal wear. Converting to Therminol 55 and $1 With fire-protection and oxidation-resistance procedures well in mind, let us turn to the matter of preparing the Therminol FR system for Therminol 55 or 66. Accumulation of debris over the years in the system could cause serious problems, especially to mechanical seals, rotary joints, etc. All heat transfer systems should be cleaned from time to time as a part of normal preventive maintenance.

M^ipstentistt: poblew# will Another reason for cleaning your systemat this time is to assure mof the Therminol FA fluid- A system deanoet is the only so- How to go about the cleanout is a matter of choice, but 'km:m some alternatives for your consideration: A, Ffaai Fbtih Cleaning This method is probably the fastest ami most effective where heating surfaces are not heavily fouled. It also offers, the advantage of not having to introduce foreign chemicals into . the system. With this method, the system is drained of Therminol FR, re-filled with Therminol 66 or 66, operated for a reasonable period of time, drained once again, and finally, recharged with fresh Therminol 55 or 66. Both the drained Therminol FR and the Therminol 55 or 66 used to flush the system may then be returned to Monsanto for disposal. B. Sokenl Cleaning . This method is satisfactory for cleaning a slightly soiled system, but chlorinated solvents must be avoided. Typical solvents used are benzene, and xylol (caution should be used with low flash point solvents). Do not use trichlorobenzene or perchloroethylene. (CAUTION: ALL SOLVENTS SHOULD BE COMPLETELY REMOVED FROM THE SYSTEM PRIOR TO OPERATING AT HIGH TEMPERATURES). Normally this is accomplished by drying the residual with warm air or by operating the refilled Therminol system at a temperature slightly above the boiling point of the solvent until the residual & vented from the system. Some caution should be used in drying the system to prevent Sashing of the solvent with resultant discharge of Therminol from the system. Both the drained Therminol FR and the flushing solvent may then be returned to Monsanto for disposal. Fluid Disposal . Monsanto offers an incineration service for the disposal of PCB heat, transfer fluids and the flushing fluids mentioned above For details of this service and how to return fluids to Monsanto for disposal, please write: .

Hdt transfer fluids sure intended only for indirect heating purposes. Under no circumstances should any. fbermjnol heat transfer fluid be allowed to come in contact with or in any way contaminate food, .animal feed, food products, food packaging materials, food handling equipment,. pharmaceuticala or any food-related items. ThlHntuitel and Thninnl 66: Safety of Handling According to the definitions of the U.S. Federal Hazardous Substances Labeling Act, Therminol 58 and 66 are not toxic substances since the oral and dermal lethal doses in animals are greater than 5 grams per kilojpi&m of body weight. Additional animal studies indicate that they do not have significant akin or eye irritation potential. It is suggested however, that good industrial practice relating to the avoidance of repeated awl prolonged skin contact to any industrial chemical, heat transfer fluids, or petroleum product be followed. Therminol 88 and 66 have such low vapor pressures at ambient temper . atrnre that inhalation of vapors during transfer of fluid from shipping containers to a heat transfer system presents no hazard. Vapors emitted by either fluid at elevated temperatures may be irritating as would be the case with excessively heated petroleum oils. .In heat transfer installations, the fluids are used in a closed, unpressurized system free from leaks and with the expansion tank vent trapped so as to condense any vapory and thus prevent their escape to the work environment. Consequently, there should be little or no opportunity for workers to experience any contact or exposure. While it is believed that Thermmol 55 and 66 pose no serious problems with respect to the environment, as a concerned supplier to industry, Monsanto urges the user to maintain a tight system, to correct leakage promptly, and to exercise care in the handling and disposal of Hus and aQ other such products. A tight maintenance program not only protects the environment, but keeps employes comfortable, the working area dean, and the system running smoothly. 12 2-32stmt* Uft?

Several rosin kettles with varldus hoal needs can bo heated Irom one Therminol ayalem. The big plus you get wilh Therminol in chemical processing, like this resin kettle, Is healing and cooling From the same system. What makes Therminol right tor your application? Hundreds of customers who have specified Thermlnol for new Installations and conversions of ex isting systems will give you these answers. LOWER CAPITAL COSTS | Without pressure you can save 25% to 50%. That's because you don't need heavy piping, relief valves or other high pressure devices. LOWER OPERATING COSTS | Fluid make-up is generally not required. Heat losses are reduced over vapor phase systems because condensate sub- cooling is not present. Routine maintenance is minimized and these non-pressured systems require only minimum attention by non-iicensed personnel. ! * ! ; I ] j J Since Therminol remains liquid throughout its tem perature range, rapid circulation through your rolls helps achieve uniform heat. This has resulted in greater throughput and Fewer rejects lor Therminol customers producing rubber, plastics and paper. MCL002087 You'll bo surprised at how easy it is to work with a Therminol heat transfer sys tem. The middle diagram at the right shows typical Therminol liquid heating and cooling systems used together to maintain very close temperature control at the user. Note that the term "heater" is usod rather than "boiler" since we do not boil Therminol in the primary heat source. Benefits of a Liquid Heating System You gain a wide spectrum of benefits with a Therminol liquid heating system. In many locations, codes favor Ther minol systems, thus minimizing the need for expensive operating personnel. Positive circulation through your users ends venting problems; tne system re mains sealed and flooded, Liquid systems respond more rapidly to your system's load changes. install your users at any level in relation to the heater; there's no condensate re moval problem. You realize a substantial cost savings with smaller pipe. Also, smaller valves control temperature more accurately-- down to 2F. No temperature loss due fo pressure drop In the piping; with vapor, any line (rlction loss results in a lower vapor condensing temperature at the users. You can meet different temperature de mands in the same user if required by certain processes by adjusting the cir culation rate. A liauid heating medium, like Ther minol, will usually give you higher heat transfer rales in certain types of users, such as shell and tube heat exchangers. Cooling can be handled In the same system. Heating systems for Therminol are sold around the world on a compet itive basis.

This bulletin lists our suggestions and experience for Therminol w Beet Transfer Fluids relative to mechanical seal problems. The most critical conditions that affect the service life of a mechanical seal are heat, pressure, corrosion, cavitation, and product characteristics. The Therminol fluids can have affect on, or be affected by, any or all of the above conditions. Other conditions such as shaft deflection, bearing wear, vibration and poor installation can also affect the life of a seal, but these problems are usually minimized by proper pump selection for the intended service and proper maintenance. Heat Excessive temperature at the mechanical seal frequency leads to premature failure. The seal environment should not normally exceed 300*P. for most heat transfer fluid applications, including the Therminol fluids. Common seal face materials, such as carbon. Stellite and Tungsten Carbide require some degree of fluid film lubrication. High temperatures decrease lubricity and the resulting friction and heat build-up can promote abnormal face wear. Therminol fluids provide excellent lubricating characteristics *below 300?. Excessive temperatures can also cause vaporization of fluid at the seal face resulting in no lubrication and/or mechanical damage to face materials such as carbon. Therminol fluids are low vapor pressure high boiling compounds that do not normally vaporize over their use range. However, some thermal decomposition products of Thermlnola 55 and 66 are lower boiling components and could cause vaporization conditions at the seal face. Dead-ended stuffing boxes provide little chance for fluid circulation and are frequently collection zones for abrasive or corrosive system dirt that can damage the seal faces. gjr -:`i 4 in box and seal gland cooling to o<^i#ii''::iilI'' temperatures, many high temperature pump #eal flush ayatetawhlcb prbvida* a ' cooled, 1 -of the' pumped' fluid to the - seal'I^cea*-1; -..-= Seal flush systems have minimized mechanical seal face wear in maey-iilgb' temperature applications* We suggest seal flush systems he considered where Iheralnol fluids are used* Pressure ' '' ' hydraulic seal face loading depends on the stuffing box pressure and type of seal used* Generally a single. Inside, unbalanced or partially balanced seal Is used in high temperature Themalnol applications. Excessive face pressure, either hydraulic or installation imposed, can reduce face lubrication, increase frictional heat build-up, and cause face distortion resulting In reduced seal face life. Pressure surges and hydraulic shock created by automatic valving within the system can also have a damaging effect on seal life* While not a common problem, proper valve selection and operation of the system hydraulics can minimize this type of overload on the seal faces. Corrosion Many heat transfer fluids can create -- through decom position or contamination -- a corrosive environment at the mechanical seal. Therrainol fluids do not normally create corrosive conditions within the heating system. And, even though most heating fluids are miscible when added together, certain chemical incompatibilities can result In a corrosive environment at the seal. Acidic conditions can result In the formation of acidic metal salts which can be abrasive to seal faces when present in the fairly quiescent environment of a dead ended pump stuffing box. When corrosive conditions develop along with corrosion by-products that affect seal characteristics, the system fluid should be changed to a fresh charge. A flush of the corrosive system may not necessarily resolve the problem since fresh fluid can loosen existing system soil. A more effective cleanout of the system may be necessary to remove the corrosive products along with other system soils.

TheraiaolN*$j 'M, 77 and 88 do not, in themselves, give rise to corrosive products that would affect seal performahM. ' ' . \. Cavitation . Cavitation -- the formation and collapse of vapor pockets from fluid near Its vapor point or from low boiling components in the fluid - does not normally have a direct effect on mechanical seals. However, frequent or continuous cavitation at the pump can bring about pressure variation (discussed above), shaft deflection, vibration or mechanical shock damage to seal components. An effect similar to cavitation, entrained gases or rapid liquid to vapor phase change, can produce a chattering effect on the seal causing face damage and leakage. System design, with attention to NPSH* requirements of the pump, usually corrects cavitation problems. Many heat transfer fluids form lower boiling components on thermal or oxidative decomposition that can result In cavitation conditions* Therminol 55 and 66 can form low boilers from thermal damage. Venting a slip stream of pumped fluid to a nitrogen or COq inerted and outside vented expansion tank will relieve low boilers from the fluid* Any vented material should be collected for proper, noa-polluting disposal. Inerting prevents oxidation damage to the fluid. `the seal flush system -- mentioned above -- provides a continuous venting of the stuffing box In addition to cooling and, even, filtering of the flush box. . Product Characteristics Characteristics of the heat transfer fluid, such as system dirt pickup, decomposition products, chemical compatibility, sludge formation, oxidation resistance, vapor pressure and lubricity ean have an effect on mechanical seal performance.

Acidic decomposition products, for example can not only catalyze further decomposition of the fluid* but establish a corrosive seal environment discussed earlier. Oxidation products from many fluids develop into abrasive carbonaceous deposits that can seriously affect seal face wear. Air contact should be minimized with those fluids having oxidative Instability. Cold or inerted (nitrogen) expansion tanks util reduce oxidation problems and potential seal problems from oxidation residues. Many fluids are chemically incompatible with one another in heating applications. Certainly, any change of heating fluid or top up with another fluid should be thoroughly evaluated to preclude seal and other system problems. Most heat transfer fluids are capable of forming high boilers and tars on thermal decomposition. Thesertars have a sludge-like characteristic and tend to be abrasive to the seal faces. * We have observed this sludge-like deposit as an uneven coating on mating seal faces which prevents sealing of the surfaces and resultant leakage. All Themine1 fluids are low vapor pressure, high boiling compounds. Vaporization of the fluid is not expected under conditions of proper pump selection and operation. Low boilers of Theminol 55 and 66 can develop occasionally from over-heating or excessive oxidation. Venting of the system, as discussed in the section on Cavitation, generally resolves the immediate problem. Certainly, we suggest attention to operating conditions that might bring about low boiler formation, e.g., air contact or over-heating. kub:rlctty: of- clean *fherinol fluids has been thorn to be adsqMli fw seal faces, even at seal environment teesttrftbi^ 300#F. Some work oh imeooled seal applications using improved face materials shows reasonable lubricity at pumped fluid temperatures approaching the fluid boiling point with 75*F However, we suggest seal environment temperatures be maintained below 3Q0#F? for long term service* Virtually all heat transfer fluid systems generate dirt or debris with use that can affect seal performance. We suggest you contact your mechanical seal or gnusp supplier to determine how seal failures oan be minimized. In summary, we feel a clean and cool mechanical seal environment ia a prerequisite to satisfactory seal service in high temperature heating systems. As a heat transfer fluid supplier, we welcome the opportun ity to work with you and your seal or pump supplier on application of the Therminol fluids.
