Natural gas is predicted to be a potential energy source in the future. However, the presence of carbon dioxide in it causes corrosion of transportation pipeline and reduction of calorific value.  Various separation technology such as adsorption, abs... see more

The use of biogas derived from palm oil mill effluent is important to combat climate change as it helps us to reduce the emission of greenhouse gases especially methane. Sime Darby built the first biogas plant at West Oil Mill, Carey Island in 2009 to ini... see more

The separation of ammonium bisulfate (ABS) from ammonium sulfate (AS) in aqueous solutions by monovalent ion selective membranes was studied. Optimised usage of these chemicals is both an important and challenging step towards a more efficient CO2 mineral... see more

The selective separation of CO2 from gas mixtures representative of flue gas generated in waste incineration systems is studied on two activated carbons obtained from pine sawdust and compared to a commercial activated carbon. Dynamic adsorption experimen... see more

Energy supply has been one of the world’s main problems. Thus, the development of new energy and renewable energy resources can be a promising solution. As one of the promising energies from biomass is bio-methane obtained from biogas purification. Membra... see more

Mixed Matrix Membranes (MMMs) which consist of 0.3 wt.% Zeolite-Carbon Composite (ZCC) dispersed in BTDA-TDI/MDI (P84 co-polyimide) have been prepared through phase inversion method by using N-methyl-2-pyrrolidone (NMP) as a solvent. Membranes were charac... see more

Hollow fiber membrane configuration is way forward in membrane development since it possesses higher packing density and effective surface area per unit module compared to other configuration. Since majority of mixed matrix membrane (MMM) for gas separati... see more

Due to its specific micropore structure, carbon molecular sieve (CMS) can provide more selective properties than conventional activated carbon in adsorbing molecule from a gaseous mixture. In this research, preparation of CMS for CO2/CH4 separation has be... see more

Removal of CO2 from natural gas and combustion exhaust gas have been studied by employing membrane permeation process. In these studies, polysulfone, polyimide and polydimethylsiloxane membranes are used to elucidate the influence of flexibility and rigid... see more
