摘要：
Several flowsheets for processing flue gases from thermal power plants to commercial-quality methanol, differing in the steps of producing the feedstock for the methanol synthesis, were considered. The dependence of the methanol yield, energy efficiency, and carbon footprint of the technology as a whole (from the step of & Scy;& Ocy;(2) capture from flue gases to the step of methanol extraction) on the composition of flue gases (& Scy;& Ocy;(2) concentration) and temperature of their flow was studied. The option of processing flue gases with high initial flow temperature using the flowsheet involving high-temperature steps of & Scy;& Ocy;(2) separation and electrolysis was considered. Taking into account the recovery of the heat from flows and steam generation, this flowsheet has high efficiency.
