Efek polietilen glikol pada membran berbahan dasar polisulfon untuk pemisahan gas co2 dan gh4

Abdul Rizal Habibi, The Effect Of Polyethylene Glycol On Membrane Based On Polysulfon For CO2 And CH4 Separation. Under Dr.Adiwar and Nurhasni,M.Si observation. Indonesia is one of the top nations in producing natural gases. The quality of natural gas noticeable so people can benefit them properly. The natural gases taken from earth. Consist of many compound. One of these is CO2. Many researches have tried to separate CO2 from natural gas using membrane is one of the methode. Membrane technology has been developed because friendly environment, low cost and simple process are the advantages of using membrane. The research aims to separated CH4 and CO2 with high purity using membrane asymmetric consisted of polysulfon and polyethylen glycol. Process of membrane construction use polymer immersion presipitation process. Membrane preparation makes through several varies: membrane with PEG and membrane without PEG, variation of time of coagulation: 4; 8; 16; 24; and 32 minute. Variation of storage: beneath water, beneath iso propanol, and in desicator. Variation of polysulfon concentration in membrane: 20; 22.5; 25; 27.5 and 30%. Variation of PEG-molecule�s weight: 600; 1000; 2000; 4000; 6000 and 10000. in last membrane saving with step-by-step polarization. Then the membrane tested with permeation cell. The operation on it is conducted by pressure 10-100 psi. the permeation from each gases will be found and recultivated to get value of selectivity Of the observation optimal membrane comes up : membrane with 10% PEG 4000, 25% polysulfon and 75% N-metil-2-pirrolidon, time of coagulation 16 minute, and under water storage. The membrane has got value selectivity reaching 18.3-66.05. Keyword: carbon dioxide, asymmetric membrane, polysulfon, polyethylene glyco
