Pure theoretical analysis: Is it better for the temperature of the MDEA lean solution to be higher or lower than the temperature of the feed gas entering the absorption tower? Refers to: absorption rate and purity of CO2 removal.
It is better for the temperature of the MDEA lean solution to be lower than that of the dry gas. This is because the rate at which MDEA absorbs CO2 increases as the temperature decreases, and the purity of the CO2 removed also improves as a result. Furthermore, lower temperatures can also reduce energy consumption and the risk of MDEA decomposition. Therefore, reducing the temperature of the MDEA lean solution can improve the efficiency of the absorption tower and the purity of the CO2 removed. .
In the learning process, it is better for the temperature of the MDEA lean solution to be lower than that of the dry gas. .
If it is too low, the hydrocarbons in natural gas will precipitate, causing the amine solution to foam
Comprehensive consideration is required: temperament composition, operating pressure, outlet specifications
