Advantages
Based on multivariate simulations of amine carbon dioxide extraction processes, the optimal concentrations of components for different biogas sources were selected, which reduces the amount of circulating absorbent and heat load of the desorber reboiler (regenerator) by 1.5-2.5 times compared to traditional monoethane solutions.
The calculations were confirmed in a laboratory using monoethanolamine and an operat-ing pressure of 0.11-0.2 MPa and did not differ from the calculated by no more than 3%.
