ABSTRACT:
Detergent-grade alkylate is produced by the HF-acid catalyzed reaction of aromatic hydrocarbons and an olefinic hydrocarbon. The process utilizes a unique fractionation facility for the recovery and use of an aromatic concentrate, and ultimate recovery of the detergent alkylate product. Integrated within the process is a combination stripping/fractionation column having a contact-condenser disposed therein.
