China’s first industrial facility for producing methanol via carbon dioxide hydrogenation comes online
Thread Content
On the morning of July 11, the groundbreaking ceremony for Anyang Shunli Environmental Protection Technology Co., Ltd.’s project to produce green and low-carbon methanol as well as LNG from CO2 was held. The project is located on South Industrial Road, Tongye Town, Yindu District, Anyang City, Henan Province, with a total investment of 700 million yuan. Upon completion and reaching full capacity, the project is expected to utilize 360 million Nm3 of coke oven gas per year, produce 110,000 tons of methanol per year, and generate 70,000 tons of LNG per year, while reducing CO2 emissions by 44 million Nm3 per year.
This project uses the coke oven gas generated by Shuncheng Group as raw material to produce methanol and, as a by-product, LNG, which can significantly reduce industrial air pollution and enable the high-value comprehensive utilization of resources. The process employed in this project differs from the conventional method used currently, which involves using CO as a carbon source to react with H to produce methanol; instead, it uses CO2 captured from industrial waste gas as the main carbon source to react with H2 to produce methanol, thereby enabling effective carbon emission reduction.
As this project utilizes Iceland’s CRI’s proprietary ETL green methanol synthesis process, as well as domestic new technologies for purifying coke oven gas through cryogenic separation to produce LNG and for CO2 capture, it produces green, low-carbon methanol along with LNG through processes such as gas compression, purification, deep cryogenic separation, methanol synthesis, and distillation. The main equipment includes: reactors, purification towers, cold boxes, heating furnaces, heat exchangers, compressors, etc. Upon completion, this project will be China’s first industrial-scale facility for producing methanol via carbon dioxide hydrogenation, and it is also the largest such facility in the world at present.
This can’t really be called a project for producing methanol from carbon dioxide and hydrogen
The main components of coke oven gas are hydrogen (55%-60%) and methane (23%-27%), along with small amounts of carbon monoxide (5%-8%), unsaturated hydrocarbons with C2 or more atoms (2%-4%), carbon dioxide (1.5%-3%), oxygen (0.3%-0.8%), and nitrogen (3%-7%). The CO2 content in coke oven gas is quite low. What is the principle behind capturing carbon dioxide in this project?
Since it is coke oven gas, the proportion of carbon dioxide is not high; does the company obtain carbon dioxide from other sources and use some of the hydrogen in the coke oven gas for hydrogenation? Or should coke oven gas be converted into syngas through reforming, and then hydrogenation be carried out using the carbon dioxide emitted during reforming? This message lacks sufficient information; is important information being deliberately hidden? But it’s certain it’s not for technical reasons; it must be for other reasons, to prevent the money collected from disappearing?
Shanghai Huayi shares experimental facilities with the Shanghai High-Energy Physics Institute of the Chinese Academy of Sciences, and has developed a methanol production process using carbon dioxide and hydrogen, backed by independent intellectual property rights.
