Calculation of the number of trays in a natural gas desulfurization tower
Thread Content
Dear experts, my plant is a natural gas purification facility with a capacity of 250,000 cubic meters per day; currently it is handling only 100,000 cubic meters per day, meaning it is operating at low capacity. Therefore, I want to reduce the number of trays in the absorption tower. How should I calculate by how much the number of trays needs to be reduced? Waiting online

1. Low load does not reduce the number of trays; instead, it causes blockages in the tray holes. 2. 10/25 = 40%, which should be within the normal operational range of the tower.
Apart from low load, the main purpose is to improve selective absorption and reduce the concentration of carbon dioxide in the acid gas.
It’s hard to say; it depends on the amount and concentration of your amine solution, as well as the design parameters of the tower internals. It is recommended to first block the holes in the tray plates to ensure the efficiency of each layer, increasing the number of tray plates to 13–15. It’s also unclear whether there are any requirements regarding the CO2 removal rate; if so, further calculations will be necessary
