Aspen absorber design
Thread Content
I want to design an absorption tower to absorb CO2. The composition of the inlet gas is approximately 20.2% CO2, 0.5% N2, and 0.3% H2, with a feed rate of 8,000 Nm3/h. The absorption liquid used is an MDEA solution, and the amine property methods are applied; however, the results show that absorption and separation are not possible! I don’t know what’s going wrong. Can anyone help me solve this? Thank you!
The intake pressure is 8 atm (absolute), and the intake temperature is 30 degrees
Chemical absorption! Add the chemical reaction section!
