Abstract
Official abstract text for this publication.
Hydrocarbon distillation columns with heat pumps and methods of operating them are described. The overhead stream is compressed to increase temperature so that it can be used both to heat the reboiler and to superheat the overhead stream before it enters the heat pump compressor.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for hydrocarbon distillation comprising: providing a hydrocarbon feed stream to a fractionation zone at a first position; fractionating the hydrocarbon feed stream into an overhead stream and a bottoms stream; heating a first portion of the overhead stream to a temperature above a dew point temperature of the overhead stream; compressing the heated first overhead stream portion; removing a portion of a stream from the fractionation zone at…
