  • Air separation process with single distillation column for combined gas turbine system
    Patent number: 4382366
    Abstract: The present invention is directed to an air separation system for the recovery of pressurized, substantially pure oxygen gas. The system uses a single pressure distillation column and burns a nitrogen-oxygen waste stream to provide power for the air compressor, the oxygen product compressor and electric generation. The distillation column has a split feed to develop reflux and reboil and to provide initial separation of the liquid and vapor components of the column.

  • Process for manufacturing liquefied methane
    Patent number: 4065278
    Abstract: A process for producing liquefied natural gas from a high pressure hydrocarbon feedstock is shown. In this process, the feedstock is isentropically expanded and distilled at a pressure lower than the critical pressure to form an overhead rich in methane and a bottom fraction. The methane rich overhead is compressed utilizing the energy obtained from the expansion and then the compressed overhead is liquefied in a refrigeration cycle.
