Construction wraps on IL alkylation units at Sinopec refineries
Construction is now completed on two revamps of brownfield units based on composite ionic liquid alkylation technology at two Sinopec subsidiary refineries.
Construction is now completed on two revamps of brownfield units based on composite ionic liquid (IL) alkylation technology at China Petroleum & Chemical Corp. (Sinopec) subsidiaries Sinopec Anqing Co.’s 161,000-b/d refinery in Anqing, Anhui Province, and Wuhan Petrochemical Co. Ltd.’s 161,000-b/d refinery in Wuhan City, Hubei Province (OGJ, Jan. 7, 2019, p. 61).
Each unit is designed to produce 300,000 tonnes/year of high-quality alkylate with research octane numbers ranging from 96-98, said Well Resources Inc., licensor for Beijing-based China University of Petroleum’s (CUP) Ionikylation process.
Commissioning of the Anqing refinery’s Ionikylation unit is scheduled for mid-July, while the Wuhan unit will be commissioned by the end of third-quarter 2019.
The completed unit revamps follow the overhaul and commissioning of a brownfield alkylation unit with Ionikylation technology at Sinopec Jiujiang Co.’s 161,000-b/d refinery in Jiujiang City, Jiangxi Province, China, earlier this year (OGJ Online, Apr. 2, 2019).
Refiners in Asia-Pacific are increasingly turning to Ionikylation alkylation technology—which uses a proprietary composite IL catalyst that eliminates reliance on more dangerous, corrosive, and hazardous chemicals such as hydrogen fluoride and sulfuric acid—as they seek to meet increasingly more stringent clean-fuel standards.
