Progress on the Completion and Improvement Projects for Yanchang Zhongmei Yulin Energy Chemical Co., Ltd. in Shaanxi / Author/Source: Huahua Network – Coal Chemical Industry / Date: 12-27-2019 / Clicks: 13. On December 23, the No. 2 desulfurization tower in the utility engineering center of the first-phase project completion and improvement project (Yanchang Jingbian Phase II project) at Yanchang Zhongmei Yulin Energy Chemical Co., Ltd. was filled with water and testing began. This marks the full entry of Tower 2 into the water-linked commissioning phase, laying the foundation for the introduction of flue gas into Tower 2. It is reported that since the flue gas modification was carried out on Tower 2# desulfurization tower on July 21, the desulfurization unit established Party member vanguard teams and youth assault teams to support the technical renovation of Tower 2# desulfurization tower. After five months, the conditions for trial operation have now been met. On December 23, the Production Department took the lead, with the Engineering Department and the Utility Center providing support, in conducting a PSSR screening for Tower No. 2 before its trial operation. The main inspection items include the individual testing of the moving equipment in Tower No. 2 for desulfurization, as well as the inspection and testing of the process water system, absorption circulation system, DCS system, and ammonia preparation system. A responsible official from the Public Utilities Center said that the technical renovation project for Tower No. 2 is a key project within the company’s efforts in safety and environmental protection. The operation of Tower No. 2 will help reduce the operational pressure on Towers No. 1 and No. 3, and it will also contribute to the company’s goals of energy conservation and emission reduction. Recently, the oil leakage pump for the primary compressor of the LDPE/EVA unit in Yulin Energy Chemical’s improvement project was successfully installed, marking the completion of all installation work on the primary compressor equipment for this unit. The goals set for this installation campaign were achieved 10 days ahead of schedule. It is understood that the compressor in question was manufactured by Buchhard; it features 8 cylinders and operates in 6 compression stages, raising the pressure of ethylene gas from 0.05 MPa (G) to 28.5 MPa (G). The unit is equipped with a cooling water station, a crankcase lubricating oil station, a cylinder lubricating oil station, an inlet buffer tank, an outlet buffer tank, inter-stage coolers, inter-stage separators, and a leak gas recovery system, with as many as 43 auxiliary devices. To ensure the successful completion of this installation work, the Polyolefins Center, service providers, the general contractor, and the installation team developed a detailed work plan. By drawing on the installation experience from other projects, they arranged in advance the materials and tools needed for the day’s installation tasks. They paid close attention to the quality of the installation work and process safety, with each participating party assigning dedicated personnel to monitor the entire process in order to prevent any quality issues or safety hazards. General goal of the installation campaign for the completion and supplementation works of Phase 1 of Shaanxi Yanchang China Coal Yulin Energy Chemical Co., Ltd. project (Yanchang Jingbian Phase 2 project): Completion of steel structure installation ； 80% of equipment installation completed ； 70% of pipeline installation completed ； Cable laying is basically complete ； The air separation unit and auxiliary facilities are generally ready for commissioning ； The regulation reservoir and Jinchisha water supply improvement project have been basically completed. Ensure the successful achievement of all annual construction goals. The completion and improvement project for the first phase of Shaanxi Yanchang China Coal Yulin Energy Chemical Co., Ltd. (Yanchang Jingbian Phase II project) involves an investment of 14.413 billion yuan. Using coal and natural gas as raw materials, this project aims to build an integrated facility capable of producing 1.8 million tons per year of methanol, 600,000 tons per year of methanol-to-olefins products, 400,000 tons per year of polypropylene, and 300,000 tons per year of low-density polyethylene/ethylene-vinyl acetate copolymer (LDPE/EVA). The project is scheduled to be put into operation in the second half of 2020. Once operational, Yueneng Chemical’s polyolefin production capacity will reach 1.9 million tons per year, making it the largest polyolefin production project in Shaanxi Province at present. http://img.yf116.cn/image/img/20191227/101433684318.jpg
