CO2 recovery for enhanced production of urea and methnaol

摘要

Anthropogenic carbon dioxide emissions are excessive and no realistic remedy for reducing them is in sight. Carbon, however, is a value product abundantly available from these anthropogenic emissions. A holistic carbon management approach allows identification of the best potentials for an economic correlation between carbon dioxide sources and carbon utilisation sinks. Urea production is one of the most lucrative applications of carbon dioxide recovery from flue gases. In this article we report on the status and operating experience of two carbon dioxide recovery processes: MHI's KM CDR Process~(TM) and Alstom's Chilled Ammonia Process.
