The first ignition of the gasifier in the clean industrial gas project produced from coal using clean energy by Jimin Kexin (Gao’an) was a success! Author/Source: Coal Chemical Engineering 114 Forum Date: June 8, 2020 Clicks: 6 On June 5, the first ignition of Gasifier No. 1 in Series 1 of the EPC project for the industrial gas production facility operated by Jinmin Kexin (Gao’an) Clean Energy Co., Ltd. (hereinafter referred to as the “Gao’an project”) was successful. This marks another significant milestone for the project, following the successful first ignition of Fly Ash Burner No. 1 on May 9; it signals the start of the feeding and testing phase for the project’s gasification unit. As of early May, less than 50% of the pressure testing for the Series 1 pipelines in the gasification unit of the Ga’an project has been completed, and less than 30% of the individual motor tests have been finished. To ensure compliance with the high-temperature furnace heating milestone on June 5, under the leadership of the project management team, the company’s Ga’an project team carefully planned the construction process. With everyone working together and putting in extra hours to overcome challenges, they made every effort to advance the project’s commissioning efforts. Since the DCS system of the gasification unit was powered on on May 10, tasks such as pipeline pressure testing at the project site, individual testing of motors, instrument calibration, pipeline purging, and individual testing of equipment were carried out one after another. In just under 25 days, the installation and pressure testing of the pipelines in the Gasification Series 1, the installation, wiring, and calibration of instruments, the individual testing of key equipment, the purging of critical systems, as well as integrated testing and commissioning were all completed, ultimately ensuring the successful first ignition of Furnace No. 1 in the Gasification Series 1 on June 5! On June 5, the first ignition of Gasification Unit 1# in Project Gao’an was successful. During the furnace drying preparation phase, the construction units XI Hua Jian, SI Hua Jian, and Wu Huan Company worked together, often putting in extra hours to complete all tasks; sometimes they even worked through the night to finish all the preparations needed for commissioning as soon as possible. Their efforts ensured a smooth testing process and helped to bring the project to completion, providing a solid foundation for the successful high-temperature first ignition of the gasification unit! On May 10, the pumps of the ammonia washing and desulfurization unit at the Ga’an project were tested. On May 18, the first gasification fan at this project was put into operation. The project is constructed in two phases: the first phase aims to produce 9 billion Nm3/year of industrial gas, while the second phase aims to produce 4 billion Nm3/year of industrial gas, which will be supplied to over 40 enterprises in the ceramics industry as clean coal-based industrial gas. Upon completion, the project will become the world’s largest coal-based clean industrial gas project to date. This project consists of a gasification unit, waste heat and energy recovery power generation units, air separation units, utility systems and auxiliary facilities, as well as a gas pipeline network within the park. The gasification unit uses CXL6000I circulating fluidized bed oxygen-enriched gasification furnaces, which were jointly developed by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences and Huangtai Gas Furnace Co., Ltd.; there are a total of 16 such furnaces with a capacity of 72,000 Nm3/h each ； The waste heat and waste energy power generation plant includes 3 130T boilers, 3 N45 turbines, and 1 C25 turbine ； The air separation unit consists of 2×32,000 capacity air separation units and 1 set of 6,000 Nm3/h all-liquid air separation unit; these three air separation units share two 16,000 KW electrically driven isothermal centrifugal raw air compressors. Located in Gao’an City, known as the “China Building Ceramics Industry Base,” this project was established by Jimin Kexin Group in the Jiangxi Province Building Ceramics Industry Base. The aim is to optimize the energy structure of this industry base, promote circular transformation within the park, develop clean energy and environmental protection industries, and thus foster healthy and sustainable economic and social development in the region. The project is carried out by Jimin Kexin (Gao’an) Clean Energy Co., Ltd., with a total investment of around 6.5 billion yuan. It covers an area of over 1,600 mu, and it is planned to build a facility capable of producing 13 billion Nm3 of clean industrial gas per year, with a calorific value of 1,500 kcal/Nm3; meanwhile, a power generation project utilizing waste heat and energy will also be developed.
