This was found to be the case, it is said, in treating what is known as Caddo crude from the Red River district in Louisiana. This is a paraffin base crude out of which but little gasoline can be obtained by the usual methods, but which has a large kerosene content, and when treated by the Greenstreet process, is claimed to yield upwards of 60 per cent by volume of high grade, water-white gasoline. The Gasoline Corporation1 manufactures a product resembling crude petroleum and having cherry-red color and sweetish odor by cracking a hydrocarbon oil of a density of 32-50 Be by heating it to 800 to 1500 F. (427-816 C.) under a pressure of 80-125 pounds in the presence of steam. A colorless gasoline substitute distilling uniformly up to 410 F. (210 C.) and of a density of 50-520 Be is said to obtained from the synthetic product by distillation. The oil is pumped through pipes to preheating coils and cracking coils. Steam is admitted at the entrance to the preheating coils and the cracking coils, and is also mixed with the products issuing from the cracking coils. The products pass to expansion or gas chambers, whose purpose is to minimize fluctuations of pressure in the apparatus, and then through pressure-controlling valves to a condenser. The liquids from the condenser flow to a collector, and the gases are led to a scrubber through which flows a stream of naphtha, the products obtained by absorption being added to those obtained by condensation. It is preferred to operate on raw materials ...
