Utilization of excess carbon dioxide
Thread Content
Our company uses coke oven gas and anthracite to produce synthetic ammonia and urea. When the urea production volume is low, carbon dioxide is released as waste gas. I would like to know how this carbon dioxide can be utilized, with the aim of finding a solution that requires minimal investment.
The previous set of membrane separation units was used to produce food-grade liquid CO2, of course, provided that there were users in the vicinity.
It depends on the level of emissions; products are planned in accordance with market demands, while also meeting the current requirements for \"reaching carbon peak and achieving carbon neutrality,\" thus achieving a win-win situation in terms of environmental benefits and economic benefits. 1) Utilizing CO2 to produce chemicals, such as methanol and ethanol or low-carbon olefins through hydrogenation techniques ； 2) Purification to produce food-grade CO2 ； 3) If the factory has excess ammonia, it can consider producing ammonium carbonate.
