Absorption Function

In this subject, a new spatial structure of the membrane contactor is explored and designed from analysis of mass transfer process, resistance theory and flow type. Under laboratory conditions, the experiment uses several methods including fluid mechanics, mass transfer process and the analysis of the fluid flow to achieve CO2 absorption function with the new hollow fiber membrane contactor. This new design of device is tested in conditions of two absorption liquids: MEA, DEA; three absorption concentrations: 6L/h, 8L/h, 10L/h; liquid velocity: 1mol/L, 0.5mol/L and air speed: 1L/min, 0.5L/min, to absorb CO2 from the gas mixture to make sure that if it has good properties. Through these experiments, we could see that the new hollow fiber membrane contactor has an increase in absorption efficiency by 10% on average.
