• W3154663005 abstract "The global warming caused by increasing emission of carbon dioxide is oneof the most serious environmental problems. Following the 1997 Kyoto Protocol,the European Union has set a goal of 20% reduction of COemission by the year2020. In order to meet this target, a significant reduction of CO release fromfossil fuel fired thermal power plants, will be required. Therefore, removal ofcarbon dioxide from flue gases is a key measure to reduce CO emission.Chemical absorption is the most practical and effective technique and is widelyused in chemical and petrochemical industry and well suited for CO capture forindustrial applications. A suitable solvent for CO absorption must be properlyselected in the capture process, since the solvent affects equipment sizing andoperating costs. MDEA as a solvent has been favored in the past few yearsbecause of its many advantages over other amines. However, the maindisadvantage of this solvent is its slow reaction rate with CO for this reason; anactivator with a very high reaction rate with CO must be added. Potassiumglycinate which has distinguishing feature of fast reaction kinetics present asuitable promoter and can act as an enhancer for MDEA when reacting with CO.Process simulation is an essential tool for the study of chemical processesbecause of its ability to predict process performance with adjustments in keyparameters, hence bypassing expensive and time-consuming testing orexperiments in pilot plants. Many researchers have simulated the CO absorptionfrom power plants and chemical processes through literature.Following the work of previous researchers, in this research a mathematicalmodel of reactive absorption of into promoted MDEA with piperazine atpacked column has been created. Validation of the created mathematical modelhas been done on actual data of absorber in an existing natural gas sweeteningprocess in Thailand called Acid Gas Removal Unit (AGRU).which is also using asolvent MDEA and piperazine as a promoter the obtained error is 3.723%.The second part of this study is developing a simulation model with anamino acid promoter, potassium glycinate, instead of piperazine in the same gasfeed condition and column configurations. the influence of various operatingvariables such as potassium glycinate concentration, solvent feed flow rate, feedtemperature of both gas and liquid stream, and finally the pressure of the absorberon absorptive capability have been examined theoretically" @default.
