Expert Consultation Meeting on the Special Report on the Environmental Impact of Groundwater due to the Relocation, Transformation, and Upgrading of Jiehua to Build a 500,000-ton Synthetic Ammonia Production Facility and Related Downstream Projects Held; Author/Source: Gasification Industry; Date: April 6, 2023; Clicks: 102. On April 2, Yuncheng Coal Group’s Jiehua Chemical Branch organized an expert consultation meeting regarding the special report on the environmental impact of groundwater as a result of the relocation, transformation, and upgrading of Jiehua to construct a 500,000-ton synthetic ammonia production facility and related downstream projects. Four ministerial-level experts in groundwater from the field of ecological environment, namely Hou Guangcai, Zhang Guo, Wu Zhiliang, and Cao Guangzhu, were invited to provide on-site guidance. Relevant leaders from the Honghe Prefecture Ecology and Environment Bureau, the Kaiyuan Branch of the Honghe Prefecture Ecology and Environment Bureau, and the Management Committee of Yunnan Kaiyuan Economic Development Zone also attended to offer their support. Wang Libing, a member of the Party Committee and deputy general manager of the company, Ma Wenliang, another deputy general manager, along with staff from the Safety and Environmental Protection Department and the Technology Department, as well as representatives from the project’s environmental impact assessment agency, China Global Engineering Co., Ltd., and the groundwater assessment agency, Yunnan Geological Engineering Exploration and Design Institute Co., Ltd., attended the meeting. Before the meeting, the expert group conducted an on-site inspection at the Xiaolongtan Industrial Park to assess the groundwater and geological conditions of the surveyed and evaluated areas ； At the meeting, the groundwater assessment team provided a detailed presentation to the expert group on aspects such as the main contents of the report, the results of hydrogeological surveys, the findings of exploration and hydrogeological tests, predictions of the project’s impact on groundwater resources, and related validations. After listening to the presentation and taking into account on-site inspections as well as a thorough review of the report materials, the expert group gave positive feedback on the groundwater thematic report, while also providing clear suggestions and recommendations regarding the investigations conducted and the analysis of site suitability. The successful holding of this meeting clarified the next steps for the environmental impact assessment work related to the relocation project of Xiehua, playing a crucial role in accelerating the transformation and upgrading of Xiehua’s operations to facilitate the construction of a 500,000-ton synthetic ammonia plant and related downstream projects. Image: Yunnan Jiehua Clean Energy Development Co., Ltd. (abbreviated as Jiehua Clean Energy) was formerly the PLA Fertilizer Factory established in 1958 in Kunming. It was the first medium-sized nitrogen fertilizer manufacturer on the Yunnan-Guizhou Plateau, as well as one of the earliest enterprises in China to use lignite as raw material and the Lurgi pressure swing gasification process to produce synthesis ammonia. In 2009, it was reorganized to become a wholly-owned subsidiary of Yunnan Coal Chemical Industry Group Co., Ltd., with its registered address in the Kunming High-Tech Development Zone. Jiehua Chemical Branch (abbreviated as “Jiehua Chemical”) is located in Kaiyuan City, Honghe Prefecture, and is a subsidiary of Jiehua Clean Energy. After 60 years of development, Jiehua Chemical has now become a coal chemical enterprise that uses lignite as its main raw material, producing over 20 types of products in the fields of fertilizers, chemicals, and clean energy, including synthetic ammonia, urea, nitroaromatics, phenols, and others. Project Overview: The 500,000-ton synthetic ammonia production facility and related downstream projects under construction are part of the initial phase of the transformation and upgrading efforts by the Jiehua Branch of Yunnan Jiehua Clean Energy Development Co., Ltd., aimed at building large-scale coal chemical plants. The project uses lignite as the main raw material to produce synthetic ammonia through processes such as gasification, purification, and ammonia synthesis. Synthetic ammonia is then used as a raw material to manufacture products such as energy-rich urea, dilute nitric acid, nitric acid plating solutions, urea-sulfur compound fertilizers, and nitro compound fertilizers. The main facilities include gasification units, purification units (including shift reaction, low-temperature methanol washing/liquid nitrogen washing, and sulfur recovery), ammonia synthesis units, air separation units, urea production units, nitric acid production units (including the relocated Nitric Acid Production Line A and the newly built Nitric Acid Production Line B), water-soluble compound fertilizer production units (including nitro compound fertilizer production lines and urea-based compound fertilizer production lines), as well as supporting utility systems (including power stations built on behalf of the industrial park), auxiliary production facilities, and living amenities.
