Zhonghe Gasification Signs Another Contract for Turnkey Project of Circulating Fluidized Bed Gasifiers – Author/Source: Gasification World, Date: 2023-04-27, Clicks: 36. Recently, Zhongke Hefei Gasification Technology Co., Ltd. (hereinafter referred to as “Zhonghe Gasification”) signed a contract with Guangxi Longzhou Xinxiang Ecological Aluminum Industry Co., Ltd. for the turnkey project of circulating fluidized bed gasifiers in the gas production area, aiming to work together on the construction of gas stations for alumina calcination. Guangxi Longzhou Xinxiang Ecological Aluminum Industry Co., Ltd. is located in Longzhou County, Chongzuo City, Guangxi, with a production capacity of 1 million tons of alumina. To control gas costs, the technical staff at Zhonghe Gasification selected a mixed coal made from low-cost Indonesian lignite and domestic bituminous coal as raw material. They designed two pulverized coal gasifiers using circulating fluidized bed gasification technology, with each gasifier having a capacity of 50,000 m3/h; once completed, these gasifiers will supply fuel gas to the calcination section. Once the project is operational, it will significantly reduce gas costs, thereby lowering the cost of the end products. As a fuel gas for industrial furnaces, gas is widely used in industries such as building materials, non-ferrous metallurgy, ceramics, and glass. Reducing the cost of gas production helps to control the cost of end products. Of the gas costs, the cost of raw coal accounts for over 80%. The circulating fluidized bed gasification technology can utilize low-cost lower-grade coal, low-quality \"three-high\" coal, and pulverized coal from thermal coal (mixed coal), thereby reducing the cost of gas. The CGAS circulating fluidized bed coal gasification technology boasts key advantages such as strong adaptability to different types of coal, low energy consumption and costs, high overall energy efficiency, low emissions of waste substances, and high technical reliability. With its economic viability, significant energy savings, and environmental friendliness, it has been selected for the **Comprehensive Service Platform for the Transformation of Ecological and Environmental Science and Technology Achievements**, and is considered a technology for the clean and efficient utilization of coal that enjoys recognition and support at the **level. As the industrialization platform for the CAS Hongguang special project titled \"Industrialization of Circulating Fluidized Bed Coal Gasification Technology,\" Zhonghe Gasification has successfully implemented the application of circulating fluidized bed technology in industrial fields such as coal-to-syngas production and coal-to-clean-gas production, and has established a number of high-quality demonstration projects that deliver benefits in terms of economy, society, and the environment. Moving forward, Zhonghe Gasification will continue to promote the application of circulating fluidized bed gasification technology in various fields, drive technological innovation in the industry, provide enterprises with clean energy solutions, and achieve high-quality development in the coal gasification and environmental protection sectors.
