Publication number: 20150047391Abstract: A system and process for separating ethane and propane from a feed stream comprising dehydrated liquefied petroleum gas is disclosed. A distillation column operates at a lower pressure and temperature than conventional distillation columns. High purity liquid propane exits the bottom of the distillation column and is flashed through a cooling control valve becoming a two-phase stream with the vapor entering a heat pump compressor. The high or increased temperature compressed propane stream exiting the heat pump compressor is directed into the distillation column to drive the separation of the ethane and propane, allowing the elimination of a reboiler from the system and process.Type: ApplicationFiled: August 13, 2014Publication date: February 19, 2015Applicant: S & B ENGINEERS AND CONSTRUCTORS, LTD.Inventors: Guy S. Suffridge, Sean C. Gattis, Marshall J. Fullwood

Patent number: 7915463Abstract: A process for converting natural gas to liquid hydrocarbons comprising heating the gas through a selected range of temperature for sufficient time and/or combustion of the gas at a sufficient temperature and under suitable conditions for a reaction time sufficient to convert a portion of the gas stream to reactive hydrocarbon products, primarily ethylene or acetylene. The gas containing acetylene may be separated such that acetylene is converted to ethylene. The ethylene product(s) may be reacted in the presence of an acidic catalyst to produce a liquid, a portion of which will be predominantly naphtha or gasoline. A portion of the incoming natural gas or hydrogen produced in the process may be used to heat the remainder of the natural gas to the selected range of temperature. Reactive gas components are used in a catalytic liquefaction step and/or for alternate chemical processing.Type: GrantFiled: January 8, 2010Date of Patent: March 29, 2011Assignee: Synfuels International, Inc.Inventors: Sean C. Gattis, Edward R. Peterson
