The tail gas generated during calcium carbide production contains substantial amounts of carbon monoxide (CO). Direct discharge without treatment not only wastes energy but also poses environmental risks. To address this issue, this study investigates advanced purification and resource recovery technologies for CO, focusing on analyzing its composition characteristics, purification mechanisms, and process optimization pathways. Through integrated applications of high-efficiency absorption, selective catalytic conversion, and membrane separation techniques, the impurity content in tail gas can be significantly reduced, enabling high-purity CO recovery. This research enhances CO utilization efficiency while providing technical support for clean energy conversion and green chemical production. Results demonstrate that strategic configuration of process units combined with energy recovery measures achieves dual objectives of cost-effectiveness and environmental sustainability in tail gas treatment.
