Huisheng Engineering Wins Another EPC Contract for Gasification-Based Hydrogen and Ammonia Production Facility Author/Source: Coal Chemical Industry 114 Forum Date: 2021-11-27 Views: 22 On November 26, Huisheng Engineering (stock code: 2236.HK) officially signed the EPC contract for the design, procurement, and construction of Phase 1 of the gasification-based hydrogen and ammonia production project with Henan Shenma Nylon Chemical Co., Ltd. This project is Huisheng Engineering’s third gasification EPC turnkey project acquired this year. The project is located in the Pingdingshan Nylon New Materials Industry Cluster. Under the contract, Huisheng Engineering will provide services such as the detailed design, procurement, construction, and pre-commissioning of the gasification system, air separation system, wastewater treatment system, and reclaimed water reuse system. Regarding the hydrogen and ammonia project to support Henan Shenma Nylon Chemical Industry, the kick-off meeting for this project was held at Saiding Company from June 4th to 5th, 2020. Henan Shenma Nylon Chemical Co., Ltd. plans to invest 2,300,665,600 yuan to upgrade its existing hydrogen production facilities in the Pingdingshan Nylon New Materials Industry Cluster in Ye County, Pingdingshan City, Henan Province. Advanced water-coal slurry gasification technology will be used in place of fixed-bed gasification technology; the facility will be capable of producing 400,000 tons per year of liquid ammonia and 50,000 Nm3/h of hydrogen, with sulfuric acid generated as a by-product. The construction of this facility will meet the raw material needs of companies in the nylon chemical and nylon technology sectors, enabling self-sufficiency in terms of raw materials. Production units: coal preparation, gasification, shift and heat recovery, low-temperature methanol washing, liquid nitrogen washing, ammonia synthesis, sulfur recovery, PSA hydrogen production, air separation units, and finished product storage areas, etc ； Utilities and auxiliary facilities include the complex building, central laboratory, central control room, substation, circulating water station, desalination station, sewage treatment plant, deaeration station, chemical storage area, etc. Process technology: Using Shenmu coal blended with locally produced high-sulfur coal from Pingdingshan as raw material, crude gas is produced through reaction in a water-coal slurry gasifier. The crude gas is then processed through shift and heat recovery units, as well as desulfurization and decarburization units, to yield purified gas. Part of this purified gas is refined through liquid nitrogen washing, compressed into syngas, and sent to an ammonia synthesis unit to produce liquid ammonia as the final product. Another portion of the purified gas is used to produce pure hydrogen under the adsorption action of the PSA hydrogen extraction unit, while the acidic gas generated by the purification unit is sent to a sulfur recovery unit to produce concentrated sulfuric acid as a by-product. Main equipment: coal mills, gasifiers, water scrubbers, shift converters, heat exchangers, coolers, compressors, steam turbines, adsorbers, pumps, tanks, liquid nitrogen cooling boxes, ice makers, transformers, and flares, etc. At the meeting, Huisheng Engineering signed a general contract for design, procurement, and construction of Phase 1 of the coal gasification-based hydrogen and ammonia production project with Henan Shenma Nylon Chemical Co., Ltd. This project is Huisheng Engineering’s third gasification EPC turnkey project acquired this year. Under the contract, Huisheng Engineering will provide services such as the detailed design, procurement, construction, and pre-commissioning of the gasification system, air separation system, wastewater treatment system, and reclaimed water reuse system. At present, the project kickoff meeting has been held, and the detailed design and procurement work are underway as planned; the project is expected to be completed in the third quarter of 2023. China Five Rings Engineering Co., Ltd. (including the consortium members China State Construction Seventh Engineering Bureau Installation Co., Ltd. and China National Chemical Engineering 11th Construction Co., Ltd.) signed a general contract for design, procurement, and construction of Bid Section 2 of the project with Henan Shenma Nylon Chemical Co., Ltd. It is understood that this project is a large-scale chemical facility built by Pingdingshan City and China Pingmei Shennma Group in order to develop the \"China Nylon City\", to establish a complete supply chain for nylon production, and to address the shortages of hydrogen and synthetic ammonia – the raw materials needed for the nylon industry. It is one of the key construction projects in Henan Province for 2020 and 2021, as well as a **strategic industrial cluster bank-enterprise cooperation project for 2020. Once completed, the project will be able to meet the raw material needs of companies in the nylon chemicals and nylon technology sectors, holding significant strategic importance for ensuring the supply of raw materials for the upstream part of the nylon industry.
