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. WebApr 30, 2013 · The boil-up rate,V, without reflux is: V = Q/λ (21) At total reflux, the reboiler heat duty is: Q = V (λ + Ht (22) where H is the liquid specific heat andtsub is condenser subcool in °C. The batch time, θbatch, at constant reflux ratio is given by: θbatch = [ (R +1)/V] (S0 – S1) = λ/V (23) TYPICAL AGITATOR CONSTANTS Table 1.
