摘要：
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%.
