The ethyl chloride make consumes between 1.8 and 3.8 percent of the ethylene and HC1 feed to oxychlorination, depending on the type and age of the oxy chlorination catalyst and reactor operation. The ethyl chloride yield loss can be reduced by lowering the HC1 concentration in the first oxychlorina tion reactor. Shell Oil Company has demonstrated that the ethyl chloride loss can be reduced by 0.5 to 0.8 percent by splitting the HC1 feed between the first and second oxychlorination reactors, rather than feeding all the HC1 to the first reactor as in the conventional Stauffer oxychlorination process. By splitting the HC1 feed, the HC1 concentration in the first reactor is reduced. The proposed control valve loop will add up to 30 percent of the total HC1 feed directly to the second reactor. In the oxychlorination reaction, the unreacted HC1 in the first reactor acts as a diluent and suppresses the flammability of the air and ethylene mixture. Shell calculates that the gas mixture in the first reactor may become flammable if the HC1 split to the second reactor is greater than 40 percent. Therefore, instrumentation will be installed to limit the HC1 flow split when it approaches 40 percent. In addition, a small com puter will be installed to continuously monitor the flammability of the first reactor. Both the HC1 flow limiting system and the computer will have redundant inputs to minimize the flammability hazard resulting from a malfunction of one input loop. At present, the reaction load carried by each reactor is adjusted where possible to prevent one reactor's catalyst from decaying appreciably before the other reactors. By splitting the HC1 flow, the reaction load of the first two reactors can be better controlled and the catalyst run life may be extended. If the pressure differential across the first oxychlorination reactor is unexpectedly increased by ethylene or air contamination, the plant may have to shut down immediately and recharge the reactor. By having the option to feed HC1 directly to the second reactor, the reaction load and pressure drop of the first reactor can be greatly reduced, allowing the plant to continue operation while the shutdown work is organized. Although the plant would be operating at reduced rates, the resulting loss in production may be less than the loss resulting from an emergency shutdown and catalyst recharge operation. RWC-lkm 10/25/77 CCR 000037568 PROCESS DESCRIPTION SPLIT HC1 FEED TO OXY VCM PLANT Piping Revisions A new monel line will be installed to carry HC1 from the acetylene hydrogenators to the inlet of the second stage oxychlorination reactor, R-302. This stream will be ratio flow controlled so that 30 percent of the total HC1 to oxy will go to R-302. Shutdown System The present oxy shutdown system will be revised so that, if the HCl to R-302 is greater than 40 percent of the total HCl flow, the HCl flow to R-302 will stop. The HCl to R-302 will be blocked in on instrument air failure and pullbutton emergency stop. s Computer The proposed computer is an Interdata 8/16 with 65K bytes of memory, dual floppy disc drives, and a 30-character per second typer. It provides 16 digital input and output lines, 16 differential or 32 single ended analog inputs, and four analog outputs. The analog Inputs can be strapped to allow input of any of the standard instrumentation signals, and the ana log outputs can be similarly strapped and have an output capability of 5 ma. Vendor literature on the computer is attached. The computer will take the air, ethylene, HCl and steam flows, and the air, ethylene, HCl, and reactor inlet and outlet temperatures and calculate an overall heat and material balance for oxy and heat and material balances for each reactor. This calculation will be made at least every five seconds. The computer will calculate and record the approach to flam mability for the R-301 inlet and outlet and the R-302 inlet and will cause an alarm to be sounded if the approach to flammability exceeds 95 percent. A high approach to flammability shutdown will not be provided at this time. Explosive Limit With a 30 percent HCl split (5.4 percent O2), the oxy system will operate closer to the explosive limit than with a 0 percent HCl split (4.5 percent O2) at the R-301 inlet. Under normal conditions (109 psig and 120C), neither of these points will be within the explosive limit (see the attached explosibility chart). The only other potentially hazardous spot is the R-301 outlet if reaction is lost. The computer will cause an alarm in this case.

Remove the existing manual loading station which puts an artifi cial signal on PS-315 for maintenance bypass. RWC-dm Revised 1/11/78 Revised 3/16/78 CCR 000037571 OXY SHUTDOWN SYSTEM REVISIONS SPLIT HC1 FEED TO OXY VCM PLANT The potential for explosive mixtures to form in oxy has been evaluated, and changes to the oxy shutdown system are proposed. Material balances have been prepared using the original flow rates as proposed by Stauffer, flows rates as the plant presently operates, and flow rates that would be experienced with HC1 split 70 percent to R-301 and 30 percent to R-302. The restrictions for the oxy shutdown proposals are represented in Figure 2. Point A represents R-301 inlet concentrations under present operating con ditions. Points A through F are the normal operating conditions for each reactor's inlet and outlet stream with the split HC1 feed. As with the present oxy flow rates, the inlet feed to R-301 is the only stream that could potentially reach explosive oxygen concentrations. If at normal R-301 split HC1 feed conditions the air rate increases to 1.54 times the ethylene flow rate, the feed reaches the explosive region as shown by Point I. When the HC1 flow to R-301 drops to 56 percent of normal total HC1 to oxy (that is, the total HC1 flow falls to 80 percent of normal with 70 percent of the total HC1 going to R-301), the feed concentration will go from Point A to Point G. With air increasing, Point J is reached and the feed to R-301 approaches the explosive level at 1.33 air-to-ethylene ratio. This leads to the selection of 80 percent of normal HC1 flow as the low shutdown point and a high air-to-ethylene ratio shutdown of 1.30 with a high ratio alarm set at 1.10. The other situation considered was the air-to-ethylene shutdown require ments with the present low HC1 shutdown remaining at 55 percent of normal. If the HC1 flow drops to 55 percent of normal and the air and ethylene feeds remain at normal rates, the mixture is at Point H. Point K shows that, at this HC1 flow rate, the air-to-ethylene ratio must be greater than 1.13 for the R-301 feed concentrations to be explosive. The segment from A to M to N shows that, under low ethylene flow conditions, the feed mixture never reaches the oxygen concentration required to make the inlet stream explosive. The present 55 percent of normal etylene flow shutdown point will provide adequate protection. Figures 3 and 4 show the shutdown points under current operating conditions and original design conditions, respectively. The air-to-ethylene ratios are taken with the existing Foxboro Model 556 pneumatic analog computer. It is necessary to change the bellows on the existing unit to a Model 80 with a scaling factor of 3.500. This change can be done off-stream with a spare computer. With these conditions, the output from FRC-303 should be fed to "A" port and FRRC-313 to "C" port. The output from "B" port goes to PS-315, PdHA-311, and PdLA-313. These should be as follows: CCR 000037572 Oxy Shutdown System Revisions Page 2 Item Air-toEthylene Ratio Set Point PS-315 1.3 11.2 psi Rising PdHA-311 1.1 8.9 psi Rising PdLA-313 0.6 4.8 psi Falling Presently, PS-315, the high ratio shutdown, is set at 6.00 psi falling signal. To bypass this shutdown for maintenance, a manual loading station is used to place an artificial signal above 12 psi on PS-315. Since PS-315 will now be set at 11.2 rising signal, the signal to PS-315 should be vented to bypass the high ratio shutdown without shutting down oxy. The manual loading station is no longer necessary and should be removed. RAR-lkm 1/11/78 OCR 000037573 OPERATING PROCEDURE SPLIT HC1 FEED TO OXY VCM PLANT General The split HC1 system has been piloted by Stauffer and is in operation at Shell's VCM plant. Its purpose is to improve yields by reducing ethyl chloride formation. It also improves oxy run length by reducing the flow through and thus the pressure drop across R-301. Because of the lower R-301 flow, the R-301 hot spot temperature is more difficult to control. For this reason, splitting of the HC1 is not done until the fifth month of an oxy catalyst run when the catalyst has begun to deactivate. This design consists of piping and instrumentation revisions and the computer. The computer only monitors the oxy system and calculates the approach to flammability. It does not have control or shutdown features. Specific Steps Start up oxy in the normal manner. Make sure the computer is operating. Make sure the HC1 line to R-302 is not blocked in. Input the S-309 HC1 strength to the computer using the teletype. When oxy is lined out at the desired rates, gradually cut HC1 into R-302. Take about an hour to switch 30 percent of the total HCl into R-302. Watch the percent flammability at the R-301 inlet (UR-321 red pen). If it exceeds 80 percent, back off on the HCl to R-302. When the lab reports a new value for S-309 HCl strength, input it to the computer using the teletype. The computer will then output an oxy material balance. If any trouble occurs, especially high percent flammability on the R-301 inlet, back off on the HCl to R-302. The shutdown system is set up to stop HCl flow to R-302 on low total HCl flow. On a planned shutdown, gradually cut the HCl out of R-302. Then shut down in the normal manner. RWC-lkm 3/16/78 CCR 00003757A CONOCO ENGINEERING CENTER PONCA CITY.

The program inputs the inlet stream's temperature; each reactor's outlet temperature; the outlet HC1 strength; the percent of differential pressure readings for air, HC1, and ethylene; and the steam produced by each reactor. With this informa tion, the program calculates an overall heat and material balance for the primary oxy reactor suite and heat and material balances for each reactor every five seconds. From the material balance the program calculates oxygen concentrations at the R-301 inlet and outlet and R-302 inlet. The oxygen concentration required for a flammable mixture is only dependant on temperature (not composition). This concentration is 7.0 mol percent at 130C (R-301 inlet), 4.6 mol percent at 250C (R-301 outlet), and 5.6 mol percent at 210C (R-302 inlet). The approach to flammability (actual percent 0 devided by percent O2 at flammability) is calculated and outputted for the above three points. An alarm (not part of the computer) will be sounded if the approach to flam mability exceeds 95 percent at any location.
