Progress on the Construction of the High-Tech Coal Chemicals Demonstration Project by Inner Mongolia Jianfeng Company. Author/Source: Huahua Net Coal Chemicals. Date: 2022-01-04. Clicks: 16. Recently, Song Ruchang, Party Secretary and Chairman of Shaanxi Dongxinyuan Company, led a team consisting of the company’s leadership team and relevant engineering and technical personnel to Wushen Banner in Ordos City, Inner Mongolia, to discuss and negotiate the implementation of Inner Mongolia Jianfeng Company’s high-tech coal chemicals demonstration project. Relying on its own technical capabilities and focusing on the clean and efficient utilization of coal in different grades, the company has adopted an industrial chain approach that involves coal pyrolysis, comprehensive utilization of the resulting gases, advanced processing of coal tar, and the generation of electricity from waste gases and solid wastes. After more than 5 years of research and development, it has carried out over 3,000 technical upgrades. Through practical application and optimization in projects involving the annual production of 1.8 million tons of semi-coke, 500,000 tons of hydrogenated coal tar, and 2×25 MW cogeneration units, a series of key innovative technologies have been developed. In line with the development strategy of Shaanxi Coal Group for the clean and efficient utilization of coal in different quality grades, this technical solution will also be \"transplanted\" to the coal chemical demonstration project of Inner Mongolia Jianfeng Company. The large-scale chemical product production project involving coal pyrolysis, coal tar hydrogenation, and coke powder gasification, operated by Inner Mongolia Jianfeng Coal Chemical Co., Ltd. under Shaanxi Coal and Chemical Industry Group, was constructed through EPC services provided by Shanghai Shengbang Chemical Technology Co., Ltd. of the same group. The total investment in this project amounts to 96.7 billion yuan; it includes facilities for producing 3.8 million tons of coal pyrolysis products per year, 250,000 tons of liquefied natural gas, 500,000 tons of coal tar hydrogenation products, 1.6 billion cubic meters of coal-based syngas, 200,000 tons of acetic acid, and 10 million tons of coal products. Additionally, the project includes infrastructure for supplying heat, electricity, water, and gas. For the first time, this project combines the pulverized coal solid rapid pyrolysis technology, which is owned as intellectual property by Shaanxi Coal and Chemical Group, with the catalytic hydrogenation technology for the delayed coking of medium-temperature coal tar to produce clean fuel oils. The biggest advantage of this project is its ability to achieve comprehensive and efficient utilization of coal resources. First, coal pyrolysis is carried out to extract the light and volatile components from the coal, yielding coal tar, coal gas, and clean raw material coke powder. Subsequently, coal tar is hydrogenated to produce fuel oils, while the excess coal gas is purified, methanized, and compressed to produce compressed natural gas, thus enabling efficient utilization of the light components in coal. It is reported that thanks to the combined use of coal-based oil and gas production, chemical product co-production, and cogeneration technologies, as well as the hierarchical utilization of energy and closed-loop recycling of resources throughout the entire process, the comprehensive resource utilization rate of this project is close to 100%.
