How does the composition of the gas entering the absorption tower affect the steam consumption in the regeneration tower?

1. Composition of the gas entering the absorption tower 2. Co-absorption rate of CO2； 3 Requirements for the quality of lean liquid ； 4 Rejection ratio ； 5 Regeneration tower bottom temperature ； 6. Temperature of the rich liquid entering the tower; 7. Number of trays in the regeneration tower. How do these seven factors affect the steam consumption of the regeneration tower?

1. The composition of the gas entering the absorption tower varies; different hydrogen sulfide concentrations result in varying amounts of amine solution being used for absorption, which in turn affects the steam consumption. 2. The co-absorption rate of CO2； It should be the amount of CO2 absorbed by the amine solution. Excessive absorption leads to high steam consumption; quality requirements for the lean liquid ； It should affect the absorption efficiency; 4 reflux ratios ； An excessively high reflux ratio results in high steam consumption. 5 Temperature at the bottom of the regeneration tower ； It should be related to the temperature of the steam, as well as the heat exchange in the reboiler at the bottom of the tower. The higher the temperature of the liquid fed into the tower, the less steam is required. It’s also related to the number of trays in the regeneration tower. . . . . . . . . :L :L
