The COpure process Technology

This technology provides a unique low cost solution to carbon monoxide recovery. Process improvements have made COPure a highly reliable source of carbon monoxide for downstream manufacture of chemicals and pharmaceuticals. COPure can be considered whenever recovery of high purity carbon monoxide is required. This is especially the case when the feed gas contains significant quantities of nitrogen and/or carbon dioxide, which need not be removed.

The COPure process selectively removes carbon monoxide by complexation/ decomplexation of carbon monoxide in a proprietary solvent containing cuprous aluminum chloride (CuAlC1₄) dissolved in an organic liquid such as toluene.

Essentially the COPure process technology absorbs carbon monoxide and slips carbon dioxide, nitrogen and other gases. Typical product recovery is 98%, and typical purity is 99%. (Higher recoveries and purities are achievable.)

The COPure process may contain various post treatment or pretreatment steps that may include, compression, hydrogenation, dehydration, hydrogen sulfide removal, carbon dioxide removal etc. that are optimized for your process and plant configuration. For example if you were going to perform a Fischer-Tropsch reaction then purification of hydrogen and recombining it with the purified carbon monoxide would be included in the process.
