Filtration and membrane separation are popular methods in gas separation since they are cost and energy efficient.Despite to air filters,there are comparatively few studies on dry gas filters,particularly at indus-trial scale.In fact,major unsolved challenges such as high efficiency,low pressure drop,long-term sta-bility,high-thermal and chemical stability and advanced physiochemical properties,are still remained.The aim of this review is to scrutinize the advanced scientific and technological practices(such as selec-tion of appropriate polymeric materials and additives,nanotechnology,modification techniques and preparation methods)towards design and fabrication of an efficient filter media for solid particles removal from the natural gas flow.Recent progresses in solid particle separation mechanisms,modeling and simulation techniques and the effect of membrane fabrication methods on its performance,strategies for modification of filter media,current challenges and future perspective are discussed.
