  • N-butane/isobutane fractionation
    Patent number: 4773968
    Abstract: An n-butane/isobutane splitter is operated by compressing the isobutane overhead to increase its condensing temperature, using the compressed overhead to heat bottoms in a reboiler, which is operated to condense the overhead and cooling the condensed overhead to a temperature no lower than the temperature on the top tray of the splitter and no higher than 20.degree. F. above the temperature on the top tray, whereby the throughput of the splitter is increased by 10 to 20%.
    Type: Grant
    Filed: December 12, 1986
    Date of Patent: September 27, 1988
    Assignee: Enterprise Products Company
    Inventors: Harry E. O'Connell, James O. Nye
  • Propylene fractionation
    Patent number: 4753667
    Abstract: A propane-propylene splitter is operated by compressing the propylene overhead to increase its condensing temperature, using the compressed overhead to heat bottoms in a reboiler, which is operated to condense the overhead and remove a maximum amount of heat from the condensed overhead, additionally cooling the condensed overhead to a temperature no lower than the temperature on the top tray of the splitter and no higher than 15.degree. F. above the temperature on the top tray, whereby the throughput of the splitter is increased by 10 to 20%.
