Author/Source: Huahua Network – Coal Chemicals. Date: 2018-02-11. Views: 30. Recently, the Environmental Protection Department of the Xinjiang Uygur Autonomous Region issued a decision regarding the environmental impact report (form) for the “400,000 tons per year coal tar hydrogenation and related projects” of Xinjiang Meihuitai Petrochemical Products Co., Ltd. It will be made public, with the publicity period running from February 8, 2018, to February 13, 2018. The 400,000 tons per year coal tar hydrogenation and related facilities project of Xinjiang Meihuitai Petrochemical Products Co., Ltd. is located in the Petrochemical Industrial Park of the Shanshan High-Tech Industrial Development Zone (Shanshan Industrial Park). The project covers an area of 28,821 square meters, with a total investment of 1,162,090,000 yuan; of this amount, 72,335,000 yuan is allocated to environmental protection measures, accounting for 6.22% of the total investment. The main project involves the construction of a 400,000 tons/year coal tar hydrogenation unit (including a 200,000 tons/year coal tar pretreatment unit, a 400,000 tons/year coal tar hydrogenation and refining unit, and a 200,000 tons/year aromatic compounds production unit), a 25,000 Nm3/h natural gas hydrogen production unit, and a 15,000 tons/year sulfur recovery unit (including a 55 t/h acidic water stripping unit, a 40 t/h solvent regeneration unit, and a 15,000 tons/year sulfur recovery unit). One phase of the construction involves a 200,000 tons/year coal tar pretreatment unit, a 400,000 tons/year coal tar hydrogenation refining unit, a natural gas hydrogen production plant with a capacity of 25,000 Nm3/h, an acidic water stripping unit with a capacity of 55 t/h, a solvent regeneration unit with a capacity of 40 t/h, and a sulfur recovery unit with a capacity of 15,000 tons/year ； In the second phase, an aromatic hydrocarbon production unit and 12 storage tanks will be constructed. For the public utility systems, a new desalination system with a capacity of 60 m3/h will be installed; the circulating water system will be expanded to a capacity of 3000 m3/h. A new air purification unit with a capacity of 3000 Nm3/h, as well as nitrogen purification and adsorption tanks with a capacity of 500 Nm3/h, will also be installed. As for other facilities such as those for water supply, power supply, heating, and office/living purposes, they will make use of the existing infrastructure at the Xinjiang Meihuitai Petrochemical Products Co., Ltd. plant. Environmental protection projects include the construction of 1 new accident water tank with a capacity of 4,000 cubic meters and 1 flare tower 110 meters high, as well as the expansion of the existing plant’s wastewater treatment facility (with a total biochemical treatment capacity of 160 cubic meters per hour). The newly built, renovated, and expanded utility and environmental protection facilities were completed as part of Phase 1.
