Henan Liyuan Coal and Coke’s 200,000-ton/year project for producing ethanol from coke oven gas yielded anhydrous ethanol with a purity of 99.8%. Author/Source: Gasification World.

On December 26, 2022, Henan Liyuan Coal and Coke Group Co., Ltd.’s 200,000-ton/year project for producing ethanol from coke oven gas successfully completed the entire production process, resulting in anhydrous ethanol with a purity of 99.8%. Beijing Petrochemical Engineering Co., Ltd. is responsible for the engineering design of the core ethanol unit in this project, while the process package was provided by Yanchang Zhongke (Dalian) Energy Technology Co., Ltd. The 200,000 tons per year project for producing anhydrous ethanol from coke oven gas was designed and constructed using the DMTE technology owned by Yanchang Zhongke Company, which involves the carbonylation and hydrogenation of dimethyl ether to produce ethanol. It represents a valuable attempt by Liyuan Group to make use of the waste gases generated by its 1.28 million tons per year coking operation, and it is the world’s first industrial demonstration project for producing anhydrous ethanol through chemical synthesis using coke oven gas. The coke oven gas collected by the coking plant is compressed, purified, and subjected to hydrocarbon recombination to separate it into usable carbon monoxide and hydrogen. These gases, together with methanol, are used in a series of ethanol synthesis reactions to produce high-purity anhydrous ethanol. The effective chemical components in coke oven gas, such as carbon, hydrogen, and oxygen, are utilized to the fullest extent at the atomic level, putting an end to the era of \"simple combustion for heat generation\". While increasing corporate efficiency, it also helps to reduce carbon emissions. The total investment in this project is around 2 billion yuan; the expected annual output value is 1.6 billion yuan, with annual profits of around 800 million yuan. It will also result in a reduction of carbon dioxide emissions of approximately 190,000 tons per year. The commissioning of Henan Liyuan’s ethanol production project using coke oven gas marks a success in the use of coke oven gas for ethanol production. This project involves the production of ethanol from industrial exhaust gases, representing yet another innovative application of ethanol technology in the coking industry. It not only solves the problem of efficient utilization of coke oven gas but also produces clean and environmentally friendly ethanol, enabling the enterprise to reduce energy consumption and emissions while improving its economic performance. This technology can be applied not only to the coking industry but also to industrial exhaust gases containing hydrogen and carbon monoxide, such as those from steel production, thereby turning waste into a valuable resource. In the fuel ethanol industry, compared to traditional ethanol production via grain fermentation, it is possible to save 600,000 tons of corn per year, contributing to China’s food security and fuel autonomy. Henan Liyuan Group’s 1.28 million tons per year coking and comprehensive gas utilization project utilizes a 6.25m rammed coke oven technology. It represents another major project in which PW coking technology is applied, following its use in the coking projects at Shandong Iron and Steel Group’s Rizhao high-quality production base and Hualing Group’s Xianggang coking plant, all designed by Shanye. In this project, the 6.25m ramming coke oven incorporates a range of advanced technologies such as air-segmented combustion assistance, asymmetric flue designs, pressure regulation for individual carbonization chambers, and anti-deformation segmental protection plates. The process package for this project was prepared by Yanchang Zhongke (Dalian) Energy Technology Co., Ltd. The project mainly involves the construction of 2×60-liter, 6.25-m high ramming coke ovens, a facility for producing methanol from coke oven gas, along with ethanol, ethyl acetate, and hydrogen; a system for generating electricity using the waste heat from the coke; advanced wastewater treatment plants; as well as various supporting production and environmental protection facilities. The total investment is estimated to be 2.6 billion yuan.
