...bean oil for paints, varnishes and soft soap, soy beans are crushed into flakes, treated with hydrocarbon solvent such as hexane or benzene. The oil and the solvent are filtered off. The solvent is recovered from the oil by distillation; from the mash by steaming under pressure. Last week's jury of scientists looked along this line of operations for vulnerable spots. They found that two 4,000-gal. tanks of hexane had not exploded. Neither had the two 50,000-gal. oil storage tanks, nor the stills, nor the pressure apparatus. The blast, in fact, seemed to have...
...efficiency of oil refining. Unlike the present method of oil refining, hydrogenation is a synthetic process. In the presence of a catalyst, hydrogen is combined with crude oil under heavy pressures, high temperatures. The combined influences of catalyst, pressure and heat cause the hydrogen and the hydrocarbon molecules to split. The hydrogen atoms immediately combine with the hydrocarbons, form the proper light oil arrangement. Hydrogenation makes possible 100% gasoline recovery from the original crude oil. Recovery from straight-run and cracking is only...
