Removal Of Vocs From Waste Gas Streams By A Hollow Fiber Permeator, Varinder Pal Malik
Theses
Removal of various VOCs from air/nitrogen feed streams using a novel hollow fiber membrane was studied. Hollow Fiber Module (HFM) used had composite silicone membranes wherein an ultrathin (~ 1μm), nonporous silicone rubber membrane layer had been plasma polymerized on a porous (porosity: 0.4) polypropylene substrate. VOCs studied were toluene, methanol, acetone, methylene chloride and hexane. Primary focus was on single VOCs, although separation of VOC mixtures was also briefly studied. HFM was found to be extremely effective in removing various VOCs from feed streams. Removal of 90-99 % of various VOCs was achieved at low feed flow rates and …
