Abstract
This invention provides a unique means of effective corrosion inhibition and corrosion inhibitor utilization in a process for the extraction of aromatics from a hydrocarbon mixture using sulfolane. The corrosion inhibitor used is an organic amine. The invention involves introduction of the inhibitor into the overhead receiver of the benzene fractionation column and the recycle of water collected in that receiver to the stripper column overhead receiver. The inhibitor is thus effectively distributed throughout the process.
