The renovation project for Huiran Industrial was signed and successfully completed. In February, a contract was signed with Jiangsu Huiran Industrial Co., Ltd. regarding the upgrade and renovation project for the air preheater at its gas plant. In May, the renovation project for the air preheater at Huiran Industrial’s gas plant was successfully completed. After the retrofit, the temperature of the hot air at the outlet of the heat exchanger rose from 190°C to 630°C. The calorific value of the dry coal gas increased from 1,200 kcal/Nm³ to 1,400 kcal/Nm³. The output of dry coal gas per unit also went up from 25,000 Nm³/h to 27,000 Nm³/h. All these figures exceeded the acceptance criteria, significantly improving both the thermal efficiency and gasification efficiency of the original coal gasification plant. This has effectively achieved the goals of reducing energy consumption and enhancing energy efficiency. 2 Projects for integrated production and research centers approved: In April, the project for a clean energy integrated production and research center with a total investment of over 300 million yuan was officially approved by the Management Committee of Anhui Chaohu Economic Development Zone. This project is an important measure taken by Sino-Hydrate to promote scientific and technological innovation, expand industrial opportunities, and strengthen the real economy; it holds great significance for the company to further refine its industrial structure and enhance its core competitiveness. 3. The first anthracite circulating fluidized bed gasifier in China was ignited. On May 18, the renovation project for Guizhou Hongsheng Chemical’s ammonia synthesis plant with an annual capacity of 300,000 tons was successfully ignited. This project is the first in China to demonstrate the application of atmospheric-pressure circulating fluidized bed gasification technology for the production of synthetic ammonia feed gas; it is also the first circulating fluidized bed gasification unit in the country to use anthracite as raw material. 4 Selected as a Highlight in the Transfer and Transformation of Scientific and Technological Achievements by the Chinese Academy of Sciences. In July, Guizhou Hongsheng Chemical’s project to upgrade its facility for the production of 300,000 tons of synthetic ammonia per year was listed as one of the \"Highlights in the Transfer and Transformation of Scientific and Technological Achievements by the Chinese Academy of Sciences in the second quarter of 2020\" (a total of 5 projects across the academy were recognized). 5 China’s first circulating fluidized bed gasification unit using high-alkali coal was put into operation. On September 18, the gasification unit project of Xinjiang Yihua was launched; this unit is the largest circulating fluidized bed gasification system of its kind currently in use in the synthetic ammonia industry in China, and it is also the first such system in the country to use high-alkali coal as raw material for producing syngas. 6. Signing of contracts for the fixed-bed indirect cooling retrofit projects with Shanxi Jinfeng, Shanxi Jinxiang, and Shanxi Jinyuan Coal Chemical In October, contracts were signed with Shanxi Jinfeng Coal Chemical Co., Ltd., Shanxi Jinxiang Coal Chemical Co., Ltd., and Shanxi Jinyuan Coal Chemical Co., Ltd. respectively regarding the upgrade and retrofit projects for indirect cooling in fixed-bed gasification processes. On October 21, the evaluation meeting for the first milestone of the second phase of the Hongguang Project, titled “Industrialization of Circulating Fluidized Bed Gasification Technology,” was held at the Datong Coal Utilization Test Base of the Institute of Engineering Thermophysics, Chinese Academy of Sciences. Zhonghe Gasification serves as the entity responsible for the industrialization of this project. 8 Obtaining the Pressure Pipeline Design License: In November, Zhonghe Gasification successfully obtained the Pressure Pipeline Design License issued by the Anhui Provincial Market Regulation Bureau, marking its official qualification to carry out design work related to pressure pipelines. On December 2, a contract was signed with Shandong Rongxin Group for the gas replacement and comprehensive utilization of coke oven gas project, as well as the comprehensive utilization of gasification fly ash resources project. Among them, the gas replacement and comprehensive utilization of coke oven gas project will adopt a circulating fluidized bed pure oxygen gasification process, while the comprehensive utilization of gasification fly ash is the company’s first environmental protection project. On December 8th, the institute was selected as a member of the board of directors of the Chinese Academy of Sciences Laboratory for Clean Combustion and Gasification of Coal, and attended the founding meeting of this board as a member institution. As a base for the commercialization of the research outcomes from this engineering laboratory, Zhonghe Gasification will continue to provide stable support for the industrialization of the laboratory’s future research findings, offering strong engineering support to the laboratory. 11 Signing of the sludge carbonization project in Qi County, Henan: On December 20, a contract was signed with ** in Qi County, Henan, for the EPC turnkey project for the carbonization of sludge from wastewater treatment plants (Phase I). This project is the first one that Zhonghe Gasification has won in the field of sludge treatment; it is also the first project in which Zhonghe Gasification has established cooperation with a local authority, marking a significant advancement in the company’s industrial development. On December 28, a Strategic Cooperation Framework Agreement was signed with Shanxi Jinmei Tianyuan Chemical Co., Ltd. and Shanxi Jinmei Group Coal Chemical Investment Co., Ltd., regarding the project to improve the energy efficiency and environmental protection aspects of Jinmei Tianyuan’s gasification processes, as well as the related technical upgrades. 13 Received the honorary title of “Specialized, Refined, Unique, and Innovative” enterprise. In December, it was awarded the honorary title of “Specialized, Refined, Unique, and Innovative” enterprise by Anhui Province and Hefei City.
