The EPC project for Jimin Kexin’s industrial gas main equipment has successfully completed the entire process. Author/Source: Coal Chemical Engineering 114 Forum Date: 2020-07-27 Clicks: 123 At 1:26 a.m. on July 25, the final step of the commissioning process for the Jimin Kexin industrial gas plant, an EPC project undertaken by China Wuhuan Company (referred to as the Ga’an Project), was completed successfully – the gas was ignited in the flare system. All related systems, including the Series 1 gasification unit, Unit 1 for ammonia washing and desulfurization, the flare system, the intermediate ash storage facility, the ammonia vaporization unit, Unit 1 for air separation, and Units 1 and 2 for burning residual carbon, were operating stably with all process parameters within normal ranges, indicating that the entire production process had been successfully established. The project is divided into 4 series, with a total of 16 set of atmospheric-pressure circulating fluidized bed gasifiers, designed to produce 9 billion Nm3 of clean industrial gas with a calorific value of 1500 kcal/Nm3 per year. All the equipment and devices used in this project are of domestic manufacture. Once completed, it will become the world’s largest coal-based clean industrial gas project, providing strong momentum for the development of new economic activities in the region and facilitating rapid industrial upgrading. It holds milestone significance in the history of transformation and green development of the ceramics industry. 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 production 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 balanced 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 complete plant for producing clean industrial gas derived from coal, with an annual production capacity of 13 billion Nm3 of gas having a calorific value of 1,500 kcal/Nm3. Additionally, a power generation facility that makes use of waste heat and energy will be installed as well.
