“…Dynes and R.M. Barrer [ 48 , 49 ], using a constant-volume variable-pressure apparatus [ 50 , 51 , 52 ] schematically shown in Figure 1 . The setup is equipped with a typical permeation test cell made of AISI316 stainless steel with PTFE sealing, where the permeate side is connected to a pump station HiCube 80 Eco (Pfeiffer Vacuum, Aslar, Germany) providing vacuum up to 1 × 10 −5 Pa.…”

“…Drugim kierunkiem rozwijania technologii membranowej dla uzyskania wysokiego stopnia koncentracji helu jest jej połączenie z kolejnym stopniem w dwóch lub trzech etapach recyklingu (Seok et al, 1986;Hale i Lokhandwala, 2005;Scholes i Ghosh, 2016;Wang et al, 2019) lub z inną technologią separacyjną (np. : PSA, TSA, Krio) (Doshi et al, 1989;Laguntsov et al, 2015;Alders et al, 2017;Atlaskin et al, 2019). Trzecim kierunkiem możliwości pozyskania helu jest opcja, w której wykorzystywany jest gaz do produkcji LNG.…”

“…The membrane gas separation method, which takes the membrane fiber medium as the separation interface, is a new type of gas absorption process with good application prospects. It has the advantages of low-energy consumption, compact structure, simple operation, and strong selectivity, and effectively overcomes the disadvantages of flooding, channeling, and foaming in traditional wet absorption equipment by non-contact between gas and liquid [8]. In recent years, a series of experiments of membrane absorption have been carried out to separate the acid gases of hydrogen sulfide (H 2 S), SO 2 , NOx.…”

“…Kartohardjono et al [14] and Wang et al [15] carried out an investigation on the characteristics of NOx removal by membrane absorption. Among these studies, the transfer of gas molecules through a membrane mainly depends on the concentration difference and the pressure difference of gas in the two sides of the membrane [16], which is accompanied by high gas driving force and large unit gas membrane area for achieving a high gas separation efficiency [8].…”
