PFTPOT FITM CriPNTKT^ Lessening Drain on Nation’s TO THE RESEARCH SCIENTIST working indefatigably in his laboratory, is due a major share of the credit for the progress that is steadily being made in conserving our crude petroleum re sources. Thri ugh the advances science is making in the refining of crude petroleum and its extraction from the ground, the day when the nation’s oil supply will be exhausted is constantly being postponed. Conservation does not only mean, as many assume, the preservation, the stoppage of use, or the hoarding of the resource. It is true that petroleum, like other natural resources—our coal, our iron, our copper—is irreplaceable. Nature will not refill with oil the sands that have been drained. But it is also true that the nation’s prosperity, security and comfort necessitate the wide use of products derived from crude petroleum. With this in mind, conservation must be taKei to mean that our oil resources must be drawn upon, refined and used without waste, in orderly response to economic re quirements. MOTOR FI EL FROM WASTE GASES Polymerization, a staggering word to the layman, is the term used to describe the latest triumph of science in the elimination of waste during the refining process. Briefly, polymeriza tion involves the production of high grade gasoline from refinery gases hitherto wasted or used as fuel. Mark ing recognition of the importance of this new process, The Atlantic Refin ing Company has built a new refinery at Atr.co, Texas, whicl includes a polym rization unit, while at its Point Breeze refinery, Philadelphia, it is erecting what will be the largest ther mal polymerization plant in the world. From gases generated during the re fining of crude petroleum, the Point Breeze plant will produce 62,500 gal lons of gasoline daily. In other words the process will make possible to produce every day 62,500 more gallons of gasoline than it would otherwise be possible to produce from the amount of crude run through the refinery. Gasoline produced fron refinery gases by polymerization is particularly well adapted to use in modern high compression engines according to The Atlantic Refining Company’s engi _ II A" n ' -s ■ neers, who point out that the possibili ties of the process in relation to future motor fuel production are truly start ling. If polymerization were adopted generally by the petroleum refining industry it is estimated that it would increase by over 1,000,000,000 gallons the amount of gasoline now being ob tained from the crude petroleum re fined annually by the industrV. This additional 1,030.000,000 gallons would supply the annual requirements of some 2,000,U0u motorists without im posing any additional drain on the na tion’s oil reserve. “CRACKED” GASOLINE Polymerization is still in its infancy but the cracking process, another tri umph of the research scientist, has al ready been in general use long enough to demonstrate both its potentialities and its results. About 25 years ago, al though the fullest possible yield from straight-run refining had been secured, the demand for gasoline began to mount rapidly, due to the increasing use of the automobile. In producing gasoline by straight-run refining, no change in chemical composition is in volved. The constituent products are simply separated out of the crude oil. “Cracked” gasoline is obtained by tak ing the heavier constituents of crude oil obtained along with gasoline in straight-run refining, and subjecting them to high temperatures in specially designed stills. What "cracking” does is to break up or crack dhe heavy constitutents of Thermal polymerizatlo ing built by The A' fining Company a Breeze Refinery, Phila produce gasoline fro gases. With a daily c 62,500 gallons of ga plant will be the largest of its type in the world, and the first to be built in the eastern United States. |n« W|hi IJf N m (?) EjOJLjJA.

The gasoline, or th,. lighter and lower boiling material, is separated out by subjecting it to much the same re fining process as the original straight run refining. Approximately 8.500,000,000 barrels of crude petroleum have been con served in the United States in the last 17 years by using the cracking process in the manufacture of motor fuel. Had it not been for cracking it would have been necessary to run nearly 22,000,- 000,000 barrels of crude oil to stills be tween January 1. 1920, and December 31, 1936. 'to produce the more than 5,000,000.000 barrels of gasoline re quired. Use of the cracking process made it possible to produce this amount of motor fuel from a little over 13,000,000.000 barrels of crude. The amount of crudi oil conserved by the cracking process represents nearly two-thirds of the currently estimated reserve. Cracking has undoubtedly been the greatest single contribution to the conservation of our petroleum supply. REJUVENATION OF OLD POOLS The third outstanding contribution to petroleum conservation that scien tists have made lies in increasing the percentage of oil extracteo from the nation’s oil pools, and in producing a second crop of oil from pools pre viously considered exhausted. Under the ordinary flowing and- pumping method of producing oil, a good part of the oil in the underground reservoir canno* be brought to the surface. The oil obstinately clings to the sands which hold it, defying the most power ful pump. Petroleum scientists set themselves to the solution of the problem of how to recover this “irrecoverable” oil. The fiYst necessity was to obtain specimens of the petroleum bearing sands, thousands of feet below the sur face. Only when the structure of these sands was definitely known would it be possible to determine how they might be forced to release their store of oil. Core drills were devised that probed the subterranean sands and brought up specimens to be analysed in the laboratory. According to the re r suits of the analysis, water, air or natural gas was introduced under pres sure. Reservoirs long give- up as ex hausted began to produce oil again. Nobody knows just how much petro leum that would otherwise have re mained in the ground and forever un usable has been recovered by such “secondary recovery” methods, but the Pennsylvania oil fields, the oldest in the world, provide a vivid example of what has been accomplished. For 78 years these Pennsylvania fields have been producing high-grade oil, but a quarter of a century ago the old timers were predicting the certain exhaus tion of the fields in another 25 or 30 years. Today, thanks largely to “secondary recovery methods, Pennsylvania has boosted its annual oil production to almost the 16,000,000-barrel peak. Where it once cost $2.00 to lift a barrel of oil to the surface the job is now being done for around 35 cents. Millions of dollars are being spent for new machinery. The landscape is dot ted with new drilling wells. One of the greatest upsurges of oil field ac tivity during the last half century haa grown out of the rejuvenation process born and bred in the science labora tory.
