The HF alkylation unit in Tianjin Refinery that adopts foreign technology is briefly described with emphasis on unit start-up and normal operation. It is concluded that the technology is mature; the engineering and construction works are of high quality; and facilities for waste disposal, safety and environment protection are satisfactory. The propylene content in feedstock, when less than 2%, has little effect on the octane number of the alkylate. For each 1℃ decrease of reaction temperature, the octane number increases by 0.14.Increasing the paraffin/olefin ration of feed enhances the octane number.
