Postcombustion CO2 capture with aqueous monoethanolamine (MEA) scrubbing is one of the most promising and wellproven techniques for reducing CO2 emissions into the atmosphere. However, this process has a critical problem: the high reboiler heat energy requirement for solvent regeneration at the stripper reboiler. To reduce the reboiler heat requirement, this paper suggests a new stripper ...

WhatsApp: +86 18203695377Abstract. ASPEN Plus simulations have been created for a CO 2 capture process based on adsorption by monoethanolamine (MEA). Three separate simulations were developed, one each for the flue gas scrubbing, recovery, and purification sections of the process. Although intended to work together, each simulation can be used and executed independently.
WhatsApp: +86 18203695377Amine scrubbing has been used to separate carbon dioxide (CO 2) from natural gas and hydrogen since is a robust technology and is ready to be tested and used on a larger scale for CO 2 capture from coalfired power plants. The minimum work requirement to separate CO 2 from coalfired flue gas and compress CO 2 to 150 bar is megawatthours per metric ton of CO 2.

WhatsApp: +86 18203695377SO 2 is formed during the combustion of coal. The amount of SO 2 produced depends on the sulfur content of the coal burned in a boiler. FGD scrubbers remove the SO 2 from a boiler's postcombustion exhaust (flue gas) by passing it through an alkaline solution. This process is also effective in removing acid gases, such as hydrochloric acid.
WhatsApp: +86 18203695377Wet limestone scrubbing has high capital and operati ng cost due to the handling of liquid reagent and waste. Nonetheless, it is the preferred process for coalfired electric utility power plants burning coal due to the low cost of limestone and SO 2 control efficiencies from 90% up to 98% (Schnelle, 2002).
