Refining - Developments in Refinery Engineering during 1932 - Summary

Any review of the engineering progress made in 1932 in the petroleum refining industry must necessarily be broad and general, improvements having been made in practically all major branches of this activity. Several factors contributed to an advancement on a wide front, much of it coming from those active in refining, considerable from those not, immediately in it but engaged in designing and installing equipment and maintaining large and capable staffs of experts in both engineering and development work. Another factor has been the ability of the refiner, because of less than capacity operation, to carry on experimental and development work in regular plant equipment. The movement to higher antiknock value gasoline has continued through 1932, and the average improvement of the more widely sold branded gasolines is from 3 to 4 points higher in the octane scale. A very great improvement was brought about during the year in the method of determining the octane number of gasoline. While the procedure and equipment for determining this value as developed by the Cooperative Fuel &search Steering Committee prior to 1932 had received fairly general acceptance, evidence that it did not always evaluate in a measure consistent with road performance quickly accumulated, and led to further effort to synchronize laboratory results with actual use. As the result of some really brilliant work on the part of the C.F.R. Committee and a large number of collaborators, it was found that a comparatively minor modification of the previously developed equipment and method gave surprisingly concordant results between laboratory tests and trial per-formance on the road. This method has been officially accepted by the Society of Automotive Engineers and the American Petroleum Institute, and will according to present plans go into general use on April 1, 1933. The American Society for Testing Materials has studied the method but at the time of writing this had not reached a final decision regarding it. Improved Volatility of Gasoline The most notable trend during the year, in addition to a very considerable increase in antiknock value referred to above, has been in the
