Generally, the gaseous feedstock stream is contacted with alkanolamine aqueous solution countercurrently in the acid gas absorber tower. The acid gas will partly be converted to non-volatile ionic species by the basic amine and partly be dissolved physically in the liquid solution. Acid gas removal unit is very important in petrochemical processing plant. There had been great numbers of studies on the solubility of CO2 in methyldiethanolamine (MDEA) aqueous solutions. M. Vahidi used extended Debye- Huckle model to explain on the solubility data of CO2 absorption in MDEA and Piperazine (PZ) at certain concentration, temperature and pressure. The average absolute relative deviation percent (AAD %) reported were 8.11%. Model of solubility of CO2 in MDEA aqueous solution using neural network mo...
