Zhejiang Petroleum and Chemical Co. Ltd., also known as Zhejiang Petrochemical Co. Ltd. (ZPC), as let a series of new contracts for technology licensing and engineering for new units to be installed at its grassroots 40 million-tonne/year integrated refining and petrochemical complex in Zhoushan, Zhejiang Province, China (OGJ Online, Feb. 14, 2017).
CB&I, Houston, will provide ZPC with the license and engineering design of a single-train 220,000-tonne/year diphenyl carbonate (DPC) unit based Versalis SPA-CB&I’s jointly licensed DPC technology process, the service provider said.
This latest contract follows ZPC’s two earlier contract awards to CB&I for licensing and engineering design of three additional units at the new complex that, alongside an alkylation unit based on CB&I’s proprietary CDAlky advanced sulfuric acid alkylation technology, includes two diesel hydrocracking units equipped with CB&I-Chevron Corp. joint venture Chevron Lummus Global LLC’s proprietary maximum-conversion Isocracking technology, according to a Dec. 15, 2016, release from CB&I.
ZPC also recently let separate contracts to DuPont Clean Technologies, a division of E.I. DuPont de Nemours & Co., to deliver engineering, technology licensing, and proprietary equipment for a MECS sulfuric acid regeneration (SAR) unit at the integrated complex, DuPont said on Apr. 12.
Designed to meet the Chinese Ministry of Environmental Protection’s current emission requirements for SO2, NOx and sulfuric acid mist, the new MECS SAR unit for ZPC will have a capacity to regenerate 858 tonnes/day of spent sulfuric acid and produce a combination of products consisting of 98.3 wt % sulfuric acid, 99.2 wt % sulfuric acid, and 20% oleum, according to DuPont.
Neither CB&I nor DuPont disclosed values of the ZPC contracts.
Established in June 2015 as a joint venture of China-based Rongsheng Holding Group Co. Ltd. 51%, Juhua Group Corp., Tongkun Group Co. Ltd., and Zhoushan Marine Comprehensive Development Investment Co. Ltd., ZPC will invest about 160 billion yuan to complete both phases of the project, Phase 1 of which is due for startup by December 2018
Planned to nearly double processing and production capabilities at the site, Phase 2 of the complex is scheduled to be commissioned during first-quarter 2021, ZPC said.
As currently proposed, the refining complex will be configured to process a mix of light, medium, and heavy crudes from Saudi Arabia and Iran, as well as Brazilian Frade, according to a 2016 environmental impact assessment for the project posted to the city of Zhoushan’s official government web site.
