Claims
- 1. An alkylation process which comprises the steps of:
- a. reacting olefins with aromatic compounds in contact with hydrogen fluoride catalyst in a reaction zone;
- b. separating from the resultant reaction mixture, in a separation zone, an alkylated aromatic product and a stream of unreacted aromatic compounds and hydrogen fluoride;
- c. removing from the reaction zone a gaseous stream containing hydrogen fluoride;
- d. removing from the separation zone a gaseous stream containing hydrogen fluoride;
- e. returning said stream of unreacted aromatic compounds and hydrogen fluoride to said reaction zone;
- f. combining said gaseous streams from step (c) and step (d) and contacting said combined gaseous streams with a portion of said alkylated aromatic product to absorb hydrogen fluoride from said combined gaseous streams into said portion of the alkylated aromatic product; and
- g. passing said portion of the alkylated aromatic product, containing absorbed hydrogen fluoride from contacting step (f) to the separation zone of step (b).
