Abstract

C02 removal using amines is well understood because of it has been widely used for acid gas removal. One way to reduce the cost of amine is by recovered and recirculated back into the process stream. Few methods have been developed to optimize the recovery of the amine. The used of membrane to remove amine from the effluent water is still devoid. Therefore, this unprecedented study will highlight the feasibility of using membrane process to separate amine from effluent water prior to discharge. It is found that the reverse osmosis method gives better performance and more reliable results than the ultra filtration membrane for amine removal from water, with salt rejection more than 90%. This is due to the smaller pore size of theRO membrane, which is less than lnm to lOnm while the UF membrane can only reject contaminants no smaller than 0.01 jam with lOnmto 100 nmpore size. Other factors affecting the membrane performance are feedwater pressure, concentration, temperature, pH, concentration polarization, and the membrane recovery. However, in this project, the parameter that had been studied in this experiment is the effect of the feed pressure and the feed concentration. From the result for the separation of amines from water, reverse osmosis give better performance in increasing the pressure as well as the feed concentration in order to get more amines at the rententate side.
