| titleOfInvention | Membrane contactor, method of preparing the same and method for separating acid gas using the same |
| abstract | The present invention is a membrane contactor comprising a membrane and an absorbent, wherein the membrane comprises a polymer membrane containing a polymer; And a surface modification layer formed on the surface of the polymer film and comprising Compound 1, wherein the absorbent is an amine compound; And glycine, sarcosine, piperazine, 2-(1-piperazinyl)-ethylamine (2-(1-piperazinyl)-ethylamine, PZEA), aminomethyl propanol , AMP), potassium carbonate (Potassium carbonate, K 2 CO 3 ), trisodium phosphate (TSP), and an additive containing at least one selected from the group consisting of tetraethylenepentamine (TEPA); including And, it relates to a membrane contactor for use in acid gas separation. The present invention has the effect of improving durability due to low wetting phenomenon, increasing CO 2 absorption efficiency, improving water repellency, minimizing damage to the membrane, and improving long-term stability of the membrane contactor. |
