Application of PSA-COtechnology in 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 the high value-added chemical product such as MEG largely reduce the raw material cost of the high-purity CO. The new-type purification device of PIONEER not only utilizes the high value-added tail gas of calcium carbide furnace, but also gives a new idea for the development of the technology of synthesis gas-to-MEG.
Successful Case
Xinjiang Tianye Group adopts the unique PSA technology of PIONEER to separate the high-purity CO from the tail gas of calcium carbide furnace to synthesize MEG. As the first industrial device synthesizing MEG by the tail gas of calcium carbide furnace in China, it completely solves the problem of tail gas reclamation. Besides, it not only promotes the emission reduction but also largely reduces the raw material cost of high-purity CO which saves a lot gas generation expenses.
