Abstract
AbstractThis chapter focuses on the energy saving and CO2 mitigation in the industry’s activities in the usage of fossil oil, low-carbon and renewable energy. It covers the topics of CO2 production, capture and storage in the energy industries. It also discusses CO2 application in the chemical industries. Ten industrial operation case studies are used in the chapter which have covered different aspects in the CO2 Generation, CO2 Capture, Delivery, Storage and Application. The operations are supported with detailed process simulations, and the results are presented for reference by readers. These cases are: Nature gas CO2 capture via acid gas enrichment—Case study 1; Cascade sour nature gas CO2 capture—Case study 2; Acid Gas Enrichment and CO2 Capture—Case Study 3; Syngas CO2 Capture with single absorber using DEPG solvent—Case study 4; Syngas CO2 Capture with dual absorber using DEPG solvent—Case study 5; Flue gas CO2 Capture using DEA solvent—Case study 6; Flue gas CO2 capture using oxygen instead of combustion air—Case Study 7; CO2 dehydration and compression—Case study 8; Flue gas CO2 Capture, compression and dehydration—Case study 9; Flue gas Cryogenic CO2 Capture—Case Study 10. A newly developed CO2 Capture Process by Cryogenics is discussed in the chapter. The innovative process will not require a contact liquid. There is no solid formation at the upstream of CO2-de-sublimation, this eliminates the concern in the sold CO2 transferring.KeywordsCO2 captureCO2 utilizationCascade CO2 captureAcid-gas enrichmentCryogenicFlue gasNatural gasSyngas
