The review of the 90% 3D model for the gasification unit of the Yushen coal-based ethanol project was completed successfully. Author/Source: Coal Chemical Engineering 114 Forum. Date: November 1, 2020. Views: 52. From October 27 to 30, 2020, a review meeting for the 90% 3D model of the gasification unit of the Yushen 500,000 tons/year coal-based ethanol project was held at the Aerospace Engineering Company. Relevant technical personnel from Yushen Nenghua Company and Aerospace Engineering Company attended the meeting. During the review period, the participants conducted a thorough evaluation and optimization of the 90% 3D model of the facility in terms of process flow, pipeline layout, on-site construction, operational inspections, operation and maintenance, as well as safety and environmental protection. At the same time, each item of the review comments for the 60% 3D models was addressed to ensure compliance with the requirements of this review. It is understood that the review of the 90% 3D model of the gasification unit represents an important milestone in the project design. The successful holding of this meeting signifies a significant advancement in the design work for the gasification unit, laying a solid foundation for the subsequent procurement of pipeline materials and the construction and installation of pipelines and equipment. Another component of the air separation unit for the Yushen ethanol project was completed ahead of schedule. On October 30, the main structure of the air separation cabinet room for Yushen’s 500,000 tons per year coal-based ethanol project was successfully finished, 10 days earlier than planned. The cabinet room is a reinforced concrete blast-resistant structure on the ground floor; its building height is 4.8 meters and its floor area is 404 square meters. These include the cabinet room, engineer’s room, UPS room, HVAC equipment room, emergency facilities room, spare parts storage area, and instrument maintenance room, among others. It is understood that since the operation of the air separation unit began, with the active cooperation of all participating units, the company has focused on meeting deadlines, ensuring safety, accelerating progress, and maintaining high quality in order to push forward the construction schedule. Multiple components were completed ahead of schedule; previously, the foundations of the air-cooling towers and water-cooling towers, as well as the sewage collection tanks and the first floor of the air separation unit’s power distribution room, were completed on October 26 and October 29 respectively. This completion of the roof structure marks a significant milestone in the development of this facility. To date, the civil construction of several other units within the facility is underway in an orderly and vigorous manner. The reinforcement binding at the bottom of the cold storage tank foundation has been completed ； The foundations for the liquid oxygen and liquid nitrogen storage tanks in the tank area have seen the pouring of the structural columns completed, and the formwork for the top slabs is currently being installed ； The roofing of the air-cooled power distribution room, the foundations of the compression plant and those beneath the compressors, the foundation of the pre-cooling pump room, the foundation beneath the air-cooled island, and the foundation of the expander plant will also be completed as planned. The Yucheng 500,000 tons per year coal-based ethanol project of Yanchang Petroleum has a total investment of 6.98 billion yuan. It is located in the Qingshui Industrial Park of the Yucheng Industrial Zone, and it utilizes the ethanol production technology based on dimethyl ether carbonylation, which was developed jointly by Yanchang Petroleum and the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences. Construction on this project officially began on November 6, 2018, with completion scheduled for the end of 2021. The successful completion of the roof structure lays a solid foundation for the project to be finished on schedule.
