CALCIUM CARBIDE FURNACE TO CO
There are nearly 400 calcium carbide manufacturing enterprises in China at present whose total annual productivity exceeds 15 million tons. More than 15 billion m3 calcium carbide furnace tail gas is produced in China every year. It mainly contains CO (75%~90%) which is total If fully discharged, equaling to the waste of 2.4 million tons of standard coal, and emits 12 million tons of CO2 and more than 900,000 tons of dust every year. It is the best way to save the energy, reduce the emission and transform the waste to treasure by reasonably utilizing CO. Application of PSA-CO technology to the calcium carbide industry Purification of CO by the PSA-CO technology may obtain the 99% high-purity CO and synthesize the high value-added chemical products, such as MEG, methyl carbonate, acetic acid, methanol, TDI and DMF. Economic Benefit More than 75% of the tail gas of calcium carbide furnace is CO. Purification of CO by the PSA technology and synthesis of ...
