Nanshan Holdings Co. Ltd.’s majority held Shandong Yulong Petrochemical Co. Ltd. has let a contract to Lummus Technology LLC to provide licensing for an alkylation unit to be installed at the planned grassroots 20-million tonnes/year (tpy) integrated refining and petrochemical complex under construction as part of the Yulong Island Refining and Chemical Integrating Project at Yulong Petrochemical Industrial Park, Yantai City, Shandong Province, China (OGJ Online, Feb. 8, 2021).
As part of the Feb. 17 contract, Lummus will license its CDAlky technology to outfit a new 400,000-tpy alkylation unit that will produce very high-octane, gasoline-blending alkylate to improve fuel efficiency and reduce environmental impacts of finished gasoline product at the site, the service provider said in a release.
Lummus’ scope of work on the project also will include delivery of basic engineering, technical services, and supply of proprietary equipment for the new unit.
This latest contract to Lummus for the Yulong Island complex follows Shandong Yulong Petrochemical’s previous award to the service provider for proprietary technologies to be implemented at the complex’s two mixed-feed crackers, an ethylbenzene-styrene monomer (EB-SM) plant, and two polypropylene (PP) plants (OGJ Online, Nov. 17, 2020).
The alkylation technology licensing contract for the proposed integrated complex also follows the operator’s nearly 2-billion yuan major contract award in 2021 to Shaanxi Chemical Construction Engineering Co. Ltd. for engineering and construction on two sections of Phase 1 of the project’s main complex, as well as construction of the refinery’s light hydrocarbon tank farm project, Shaanxi said in a release on Jan. 22, 2022.
While local media out of China have reported other unconfirmed contracts let for work on Phase 1 of the planned complex, Nanshan has revealed scant information about the project, seemingly because of financial constraints in advancing construction of the proposed megacomplex.
In late 2021, Nanshan alongside fellow partners Wanhua Chemical Group Co. Ltd. and China Hualu Group Co. Ltd. jointly entered a capital increase and expansion, or equity restructuring, agreement for Shangdong Yulong Petrochemical with Shandong Energy Group Co. Ltd.—a Shandong provincial government entity—under which Shandong Energy replaced former investor Shandong Development & Investment Holding Group Co. Ltd. to take a 46.1% interest in the project, according to separate notices from Shandong Supervision Office of National Energy Administration and Shandong Energy posted on Nov. 22, 2021.
Under the revised partnership, Nanshan will hold a 51% interest in Shandong Yulong Petrochemical, with Wanhua and Hualu to hold a combined 2.9% interest in the venture, according to Chinese local media.
With new partners in place and to be fast-tracked in line with China’s ecological priority for a green, low-carbon future, Phase 1 of Shandong Yulong Petrochemical’s planned complex is scheduled for startup in June 2023, Nanshan said in a Nov. 23, 2021.
Budgeted at an investment of nearly 127.4-billion yuan, official project documents from China’s Ministry of Ecology and Environment (MEE) show the Yulong Island Refining and Chemical Integrating Project (Phase 1)—which began construction in late-October 2020—will include the following major units and available planned capacities in addition to the newly announced alkylation unit:
