CHEMICAL SHEET rCmr chemkril sheet lead is made from the best grades of Missouri- chemical lead, which insures a product of the proper composition to give the maxi mum.in acid-resisting qualities., Uniform in thickness ahcTfree from irregularities, it is furnished in any gauge from up and in some weights in sheets as large as 12'x 40'. CRAWLPROOF SHEET This is the newest. development in sheet lead--a chemical lead sheet! reinforced inside with antimonial lead supporting bars. Crawlpfoof sheet is designed especially to prevent buckling, stretching and wrinkling. Supplied in any thickness from up and in any size sheet noi'exceedingj S' in width by 25' in length. SHEET LEAD ' Sheet lead of. our manufacture is in use in many plants throughout the country and. may be depended upon to render satisfactory service in withstandingthe action of ammonia gas, phosphoric add, sulphuric acid, electrolytic solutions, etc/ As noted above/ we .are in a position to supply three kinds of sheet leadratitimonial, chemical and crawiproof- or reinforced. Which particular type Will best, meet requirements in a given case can be determined only.'when all condi tions surrottnding - thd proposed installation' are known. In ithis. connection, the-advice of our techni cal staff is (always available. Simply get .in touch .with our nearest office. . ANZIMOJUAL SHEET Antimonfal sheet lead is lead alloyed with various percentages of antimony to impart hardness and other desired properties/ It possesses a high degree of add resistance and under certain conditions has advantages. over; chemical sheet because of:greater rigidity and strength. j|s elastic liinit'rs five times that of chemi cal lead, itjsjterisiie strength double, and it also has a lower specific gravity. ` We can Siipply jantiraonial sheet m any gauge or thickness desired down to %4" and can furnish sheets, in some weights, as large as 8' wide by 25' long. ' V LEAD PIPE We make both antimonial lead pipe and chemical lead pipe. Only high, quality materials are used and our.pipe will be found to be of proper wall thickness, thus insuring correct weight per foot. Antimpnial lead pipe, as well is chemical lead pipe, is supplied by. us in sizes up to 12" inside diameter and in various wall thicknesses. Catalog listing pipe sizes furnished on (request. GENERAL We are always glad to advise on sheet lead installa tions and to submit estimates based on blue prints or specifications. In ordering sheet lead please state, in case plain rectangle sheets are desired, thickness or weight per foot, width and length.

PROCESS /- The Simonson-Mantius Vacuum Process, patented. ( in the United States and'foreign countries,-has been, adopted by a large number of oil refineries for the concentration of separated sludge add, by chemical plants for the: recovery of spent acids/drid by cham ber add plants1 for the concentration of weak chamber add. '" . The salient feature of this process is that the work is carried on un4er high vacuum with indirect' separators at a density of from 25 to 45 .Be. is con centrated by our process to 56, 61 or 66 Be. Where necessary the partially concentrated acid of 56 Be. is allowed to settle so as to remove tarry mat ter which has been separated by the decomposition of sulphonic adds, and then, further concentrated to d 6 Be. The 61 Be. add cam be used without further con centration for the treating of light oils and pressure distillates, or it can be reinforced with oleum to an acid of higher density and then used for treating kerosenes and lubricating oils. In refineries requiring 98% add for the treatment of their oils, the 61 add is used for the absorption of SO? produced in a contact plant. Under normal conditions the1 total cost of concen trating from 30 to !6j6 Be. will! v^ry from $4 to $8 per application of heat. The,-use; of vacuum has very ton of finished acid, and tire concentration to 61 Be. decided advantages, as.it eliminates all'fumes-, and only will!cost from $1.50 to $4 per ton. leakage, materially decreases add losses and reduces fuel consumption by lowering the boiling point ot the acid and -radiation looses;" Recent developments; have brought about the per fection of the SUPER VACUUM Concentrator, which is operated under a vacuum of 29.7". Because of this very high vacuum it'is jnpw possible to;concentrate acid to any desired,density up to 66 Be. in one Appa ratus, using only 100 ibjs. steam pressure as heating Operating costs depend On the- size of the plant and the.figures given are exclusive of overhead and depredation.
