2. Absorption with non-isothermal systems ∵ Heat with the solution→E=f(h)→T=f(h) We need to make heat balance overall tower → temperature profile→ determine E=f(h) →ye=f(x,E) 3. Relationships between ky or k and concentrations of y and x for gas phase and liquid p hase So the calculations for absorption from rich gases are those from poor gases
