2020/10/14 · Permeate flux of SP-2 is lower than that of PTFE, mainly due to the higher thickness of SP-2 membrane compared with PTFE membrane. It is well established in the literature that the higher thickness has a beneficial effect on the heat loss (Alkhudhiri et al. 2012 ) through the membrane and detrimental effect on the permeate flux due to the higher imposed mass transfer resistance (Shirazi et

2021/6/28 · Scientists of Tomsk Polytechnic University were able to obtain polytetrafluoroethylene (PTFE) membranes using electrospinning. PTFE is known to be the most stable existent polymer. According to the scientists, it is a simple, affordable and easily scalable method, which will allow obtaining chemically stable membranes in industrial-scale production. The membranes can be used in petrochemical

Membrane processes have wide industrial ap This handbook reviews the published litera plications covering many existing and emerging ture, presents an in-depth description of com uses in the

Poly (vinyl alcohol) (PVA) PVA is a non-toxic, biodegradable, hydrophilic, and inexpensive polymer used to produce hybrid membranes in a fuel cell, wastewater treatment, gas separation, and pervaporation. Usually, PVA is obtained from full or partial hydrolysis of poly (vinyl acetate) (PVAc) ( Fig. 16) [66], [67].

The use of membrane contactor in industrial processes is wide, and lately it started to be used in CO 2 capture process mainly for gas purification or to reduce the emission. Use of the membrane contactor provides high contact surface area so the size of the absorber unit significantly decreases, which is an important factor for commercialization. The research has been caried out regarding the
