摘要

A waste slip-stream is generated from the reclaiming process of monoethanolamine (MEA) based Post-Combustion Capture (PCC).It mainly consists of MEA itself,ammonium,heat-stable salts (HSS),carbamate polymers,and water.In this study,the waste quantity and nature are characterized for Fluor's Econamine FGSM coal-fired CO_2 capture base case.Waste management options,including reuse,recycling,treatment,and disposal,are investigated due to the need for a more environmentally sound handling.Regulations,economic potential,and associated costs are also evaluated.The technical,economic,and regulation assessment suggests waste reuse for NO_x scrubbing.Moreover,a high thermal condition is deemed as an effective technique for waste destruction,leading to considerations of waste recycling into a coal burner or incineration.As a means of treatment,three secondary-biological processes covering Complete-Mix Activated Sludge (CMAS),oxidation ditch,and trickling filter are designed to meet the wastewater standards in the United Arab Emirates (UAE).From the economic point of view,the value of waste as a NO_x scrubbing agent is 6 561 600-7 348 992 USD/year.The secondary-biological treatment cost is 0.017-0.02 USD/ton of CO_2,while the cost of an on-site incinerator is 0.031 USD/ton of CO_2 captured.In conclusion,secondary biological treatment is found to be the most economical option.
