Thread Content

Recently, the 230-ton ammonia synthesis tower for the Guizhou Qixin Coal Deep Processing and Comprehensive Utilization Project, designed and managed by Saiding Engineering Co., Ltd., was successfully lifted into place. The lifting of the synthesis tower marks the official entry of the project construction into the stage of process pipeline installation. Phase 1 of the project will enable the production of 1.2 million tons per year of coke, 200,000 tons per year of synthetic ammonia, 62,000 tons per year of coal tar, and 20,000 tons per year of crude benzene, among other chemical products. The coal deep processing and comprehensive utilization project of Guizhou Qixin Industrial Co., Ltd. involves the production of synthetic ammonia from coke oven gas, and it comprises processes such as atmospheric pressure adsorption, gas storage tanks, compression of coke oven gas, pretreatment, advanced desulfurization, conversion, and ammonia synthesis. The project is located in the Qingkeng Industrial Zone of Weng’an County, Qiannan Prefecture, Guizhou Province, and is a key project in Guizhou Province. The project aims to save resources, extend the industrial chain, increase added value, and raise the comprehensive utilization rate of resources, in order to create a green, environmentally friendly, clean, energy-efficient, technologically advanced, and highly efficient integrated production base. Upon completion, the project will play a significant role in promoting the optimization and upgrading of Guizhou Province’s coal industry, improving the efficiency of coal resource utilization, and ensuring the sustainable development of this industry. The Zhejiang branch undertook the construction of areas such as the project-based production facilities, auxiliary systems and external pipelines, as well as the ammonia synthesis plant, with a total construction period of 300 days. Guizhou Qixin’s 1.2 million-ton coking project includes coal preparation, coking, chemical recovery, power generation, washing and sorting, as well as chemical processing units. It produces 1.2 million tons of coke per year, 65,000 tons of tar per year, 20,000 tons of crude benzene per year, 18,000 tons of ammonium sulfate per year, 580 million cubic meters of coke oven gas per year, 12 million tons of washed raw coal per year, and generates 240 million kilowatt-hours of electricity per year. Synthetic ammonia of 200,000 tons per year is produced using coke oven gas, while LNG amounts to 5,000 tons per year. Total project investment: 2,030,349,200 yuan.
