On January 4, Hangzhou Demasi Gas Equipment Engineering Co., Ltd. announced that following the successful implementation of projects by Jinhong Gas (Zibo) and Shaanxi Xinghua, the company has once again demonstrated its strength in this industry by winning the bid for a 2X120,000 Nm³/h air separation unit project to support the annual production of 800,000 tons of coal-based olefins at Xinjiang Dongming Plastic. This project is the largest order to date for electric-driven high-end air separation equipment in China. It represents another achievement for the company in its efforts to expand its presence in the Xinjiang market, and it marks another significant step forward in its strategic planning in the field of large-scale air separation systems both in Xinjiang and across the country. With this series of successful projects, Demas continues to demonstrate its strong capabilities in the field of high-end equipment, thereby providing strong impetus for the high-quality development of the company. The project of Dongfang Hope Group’s Xinjiang Dongming Plastics Co., Ltd. to produce 800,000 tons of coal-based olefins per year: Project name: Construction of Dongfang Hope Group’s Xinjiang Dongming Plastics Co., Ltd. project for producing 800,000 tons of coal-based olefins per year. Location: Modern Coal Chemical Industry Demonstration Zone, Zhundong Economic and Technological Development Zone, Xinjiang. Contractor: Xinjiang Dongming Plastics Co., Ltd. Land area required: Approximately 186.4 m2. Scale of construction: Methanol is produced using coal as raw material; thereafter, through MTO units and olefin separation processes, polymeric-grade ethylene and propylene are generated. Some of these polymeric-grade ethylene and propylene are used in PP and PE polymerization processes to produce polyolefin products, while another portion is used in the production of EPDM rubber. The facility includes facilities for producing 220x104 tons per year of methanol (in pure form), including air separation, gasification, conversion, and purification processes; 80x104 tons per year of coal-based olefins (including olefin separation processes); 400,000 tons per year of polypropylene; and 400,000 tons per year of polyethylene. In addition to its main products of PP, PE, and EPDM, the plant also produces by-products such as sulfur, liquefied petroleum gas, and heavy C4+. Investment and construction plan: The total investment for the project is 1,896,744 million yuan (including 378,350 thousand US dollars in foreign currency), of which the capital expenditure amounts to 1,755,881 million yuan (including 378,350 thousand US dollars in foreign currency). The interest on loans during the construction period is 102,591 million yuan, while the working capital required is 38,272 million yuan. The planned construction period is 24 months, with commencement scheduled for April 2024 and completion by April 2026. Project engineering components: The project components mainly include the main structure, auxiliary works, utility systems, storage and transportation facilities, environmental protection measures, and supporting projects. The main components of the project include: gasification unit, shift unit, low-temperature methanol washing unit, sulfur recovery unit, methanol synthesis unit, methanol to olefins unit, olefin separation unit, polyethylene plant, polypropylene plant, ethylene propylene diene monomer plant, and water electrolysis unit. Auxiliary facilities include air separation units, raw coal pre-drying units, flare systems, fire protection systems, maintenance areas, offices and laboratories, as well as telecommunications systems.
