WebThe lower the reboiler duty, the lower the reflux ratio will be and thus the tower must have more trays. Typically, for a stripper with 20 trays the reboiler duties will be as follows: MEA system —1000-1200 Btu/lbs (280-330 MJ/m 3) lean solution. DEA system —900-1000 Btu/lbs (250-280 MJ/m 3) lean solution.
