Excerpt from Purification of Hydrocarbons by Crystallization From Liquid Methane: Isolation of 2-Methylheptane From PetroleumThe natural gas which was used as a source of methane was trans ported in light metal tanks having pressure gages attached. (such tanks are obtainable on the market as gas sample tanks. Larger tanks, such as household hot-water reservoirs, were used for storage while the smaller tanks were in shipment. The condensation of the gases from the reservoirs was carried out under a pressure of 50 or 60 pounds.For the treatment of larger quantities of material the apparatus shown in figure 2 was used. It was essentially a basket centrifuge designed to operate economically with regard to cooling agent at liquid-air temperatures and which was sufficiently gas-tight to permit recovery of the volatile gases contained in it. The gases were rectified for subsequent use in the condensing train shown in figure 3.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
