Shenghong Refining & Chemical (Lianyungang) Co. Ltd. (SRCLC), a subsidiary of Shenghong Petrochemical Group Co. Ltd., has let a contract to Axens to provide residue hydrocracking process technology to boost naphtha production at its integrated complex in Lianyungang City in China’s province of Jiangsu.
As part of the contract for key units of SRCLC’s residue valorization project at the complex, Axens will deliver its proprietary ebullated-bed residue hydrocracking technology H-Oil for a 3.2 million-tonnes/year unit in combination with a 3.45 million-tpy distillates hydrocracking technology HyK unit, Axens said on Apr. 24.
The H-Oil unit will apply supported catalysts from Shell Catalysts & Technologies in conjunction with HTI’s HCAT hydrocracking technology to maximize performances, with the high-quality unconverted residue to feed the complex’s existing coking unit.
The maxi-naphtha distillate HyK unit will apply advanced catalytic solution in combination with high-efficiency heat integration provided by spiraled-tube heat exchangers technology from Zhenhai Petrochemical Jianan Engineering Co. Ltd., according to Axens.
Alongside vacuum residue, Axens’ solution for the project also will handle py-oil from the steam cracker as feed to the H-Oil unit and effluents from the coker to the HyK unit.
The routing optimization between the distillate hydrocracking HyK unit and the H-Oil unit will enable delivery of superior naphtha yields as well as improve the coker’s feed quality, the service provider said.
Axens’ scope of work under the contract will include supply of HyK catalysts, equipment, and other services from plant personnel training to plant startup services.
Axens said SRCLC’s residue valorization project aims to increase naphtha production capacity at the site by 3.6 million tpy in single-train units.
The service provider disclosed neither a value of the contract nor a timeframe for the project’s completion.
