Abstract
A process for the production of alkylaromatic hydrocarbons by alkylating aromatic hydrocarbons with linear olefinic hydrocarbons is disclosed. The linear olefinic hydrocarbons are produced by dehydrogenating linear paraffinic hydrocarbons which are extracted from a heartcut that is distilled from a kerosene boiling range fraction in either a dividing wall fractionation column or in two fully thermally coupled fractionation columns. The process significantly decreases the cost of utilities in producing alkylaromatic precursors for detergent manufacture.
