Title: Improvements in methods of converting heavy hydrocarbons into gasoline and light hydrocarbons
Filed: 1923-12-10
Abstract: 232,283. Golby, F. W., (Gasoline Products Co., Inc.). Dec. 10, 1923. Hydrocarbons, cracking.- In producing light hydrocarbons such as gasoline from heavier hydrocarbons such as fuel oil, crude or topped oil, &c. a portion of the oil is cracked by passing it under pressure through a heated coil and into a reaction chamber and the cracked oil is blended on discharge from the reaction chamber into a vaporizing chamber with an oil which has been heated to a temperature which will produce substantial distillation. Oil from a supply pipe 1 is forced by a pump 6 through furnace-heated tubes 9 and through pipes 12, 13 into a vaporizing chamber 14 from which the residual oil passes through a valve 16, controlled by a liquidregulating device 15, and through a coil in the cooling-tank 18 to a tank 20 from which it is returned to the circuit by a pipe 3. The vapours pass by a pipe 21 through a dephlegmator 22 and thence by a pipe 28 through a cooling coil in tank 18. The condensate. then passes through a tank 32. The reflux liquid from the dephlegmator 22 passes through a cooling-coil to a tank 27. This liquid or a fresh supply of oil is passed by a pipe 35 and a pump 36 under pressure, of 300 lbs. per sq. in. or more through cracking-tubes 38, 40, in which it becomes heated to 800-900‹ F. and into an insulated reaction-chamber 43. The hot cracked oil is released through a pipe 13 in which it is blended with the hot oil from the tubes 9, and is passed into the vaporizing-chamber 14. Hot oil from the dephlegmator 22 may be passed, without being cooled, to the pipe 35 by a pipe 49 and pump 51. The tubes 9 may be heated to 410-600‹ F. when the oil is only to be topped or up to 850‹ F. under pressures up to 100 lbs. per sq. in. when fuel oil or topped crude is passed through the tubes.
