H y d r o c a r b o n oils, distilling and cracking.-In converting heavy into light oils by distillation under pressure, for example by the process described in S p e c i f i c a - tion 29,862/12, a battery of stills is employed, and the gases produced in stills in an advanced stage of distillation are utilized to give the initial pressure in a freshly-charged still. As shown in plan in Fig. 1, the outlet pipe 7 from the condenser 6 of each of the stills 1 leads to a drum 8. From the upper part of each of the drums 8 a pipe 14 leads the gases to mains 16, 17, and from the lower part a pipe 9 leads distillates to mains 11, 12 and a pipe 21 leads the water driven over at the beginning of the operation to a gutter 22. The requisite pressure of 70-75 lb. per sq. in. is maintained in the mains 12, 17 by manipulation of the valves 13<1> and 18<1>, 20. After the water is driven off from a freshly-charged still, the branch 14<a> is closed by means of a valve, and the branch 14<b> is opened, thus allowing the gases generated in the other stills to pass from the main 17 into the freshly-charged still. When the temperature has been raised to 650‹ F., the branch 10<a> is closed and the branch 10<b> leading to the main 12 is opened for the collection of high-grade distillate. The connexions are reversed at the close of the distillation, the lowgrade distillate then obtained being collected in the main 11.
