The present study shows a technical-economical analysis of a lineal alkylbenzene production plant, basing it on alkylation of kerosene with benzene and hydrofluoric acid, being the most commercially used method. The purpose of this project is to expose the different equipment used in the composition of a 260.000 t/year production of lineal alkylbenzene in an alkylation unit and to do an estimation of inversion costs. The alkylation Unit is formed by the Unifining unit, in charge to eliminate the harmful compounds of the kerosene; the Molex unit, responsible of separating linear paraffins from the branched ones using a zeolite 5A sieve; the Pacol unit, with the aim of converting linear paraffins into linear olefins; the Define unit, which consists on the transformation of the diolefins formed in the Pacol unit into linear olefins and, finally, the alkylation stage where the linear olefins are transformed into LAB with benzene using hydrofluoric acid as a catalyst.
