“…The carrier is expected to interact with one component of the gaseous stream (usually the olefin), increasing the apparent solubility and permeability of the compound in the membrane material [8,110]. Usually, the carrier contains a metal atom with free valences that make possible the electronic interaction with the electronic cloud of the carbon double bond of olefins [8,[111][112][113]. It is important to notice that the number of studies involving separations of mixtures of paraffins with other gases is expressive.…”

Bibliometric studies allow to collect, organize and process information that can be used to guide the development of research and innovation and to provide basis for decision-making. Paraffin/olefin separations constitute an important industrial issue because cryogenic separation methods are frequently needed in industrial sites and are very expensive. As a consequence, the use of membrane separation processes has been extensively encouraged and has become an attractive alternative for commercial separation processes, as this may lead to reduction of production costs, equipment size, energy consumption and waste generation. For these reasons, a bibliometric survey of paraffin/olefin membrane separation processes is carried out in the present study in order to evaluate the maturity of the technology for this specific application. Although different studies have proposed the use of distinct alternatives for olefin/paraffin separations, the present work makes clear that consensus has yet to be reached among researchers and technicians regarding the specific membranes and operation conditions that will make these processes scalable for large-scale commercial applications.

“…The average pore size, thickness of the selective layer and pore size distribution depend on the spinning dope composition and HF preparation conditions [6,7]. Recently, Polysulfone (PSf) has been widely investigated as a base polymers for the modi cation of HF Membranes in order to give some special functions to micro ltration (MF) and ultra ltration (UF) membranes [8][9][10][11].…”

The aim of the present work is to investigate the effect of post treatment of Polysulfone (PSf) hollow fiber membrane prepared by dry/wet spinning on the characteristics and performance of treated membranes. Also, the effect of coating of selected post-treated hollow fiber (HF) membrane on characteristics and performance is investigated. The Polysulfone hollow fiber membranes were prepared under controlled conditions. The post-treatments of HF membranes included treatment by soaking in magnesium sulphate 0.1%, water at 80 oC, sodium hypochlorite (0.1% ) and ethanol/isopropanol (0.1%). The last post-treated hollow fiber membranes were coated to form a thin polyamide layer via interfacial polymerization at controlled conditions. HF membranes were characterized by SEM, AFM, contact angle, porosity, and mechanical properties. The membrane performance with respect to water permeability under pressure up to 3 bar was investigated. The results of the investigation referred to the merits of each of post-treatment with respect to membrane hydrophobicity, membrane surface roughness and mechanical properties as will as water permeability. Further, the coating of post treated membrane produced membranes with low water permeability which could be suitable for membrane separation applications such as UF and NF. Testing of membrane rejection and water flux for different solutes and different conditions is recommended for future work.

“…The 2019 review contains studies on the influence of the nature and composition of the internal coagulant, its temperature, and the contact time of the casting polymer solution with it [10]. The latest review of 2020 contains research on the development of casting methods of HF membranes that are safe for humans and the environment [11] Polysulfone (PSf) is one of the most common polymers for the manufacture of HF membranes for micro-, ultrafiltration, gas separation, and membrane contactors [12][13][14]. In scientific works on the formation of HF membranes from this polymer, the influence of the molecular weight and concentration of the matrix polymer, the solvent used, the type of pore-forming agent, its molecular weight and concentration, the nature and composition of the coagulant on their transport and separation properties has been studied in detail [15][16][17][18].…”

This article describes a new technique for the preparation of hollow fiber (HF) membrane samples using an automatic manipulator unit. The manipulator uses a syringe needle to form a HF of a given geometry. The needle in automatic mode is sequentially immersed, first into the polymer solution and then into the coagulation bath. The possibility of using a manipulator to obtain HF samples was studied on the known polysulfone (PSf)/N-methylpyrrolidone (NMP)/pore-forming additive system. A series of HF membrane samples were made within 29 h from twelve 1 mL PSf casting solutions. This was 15 times faster than obtaining samples of HF membranes at the multifunctional research laboratory facility. From the point of view of the consumption of the components of the casting solution, the use of the manipulator was 30 times more economical, and the consumption of water for precipitation and washing was 8000 times less. The developed method made it possible to study samples of HF by scanning electron microscopy (SEM), ultrafiltration, and evaluate its mechanical properties without spinning the membranes. Using the new technique, the optimal composition of the casting solution for the wet spinning of HF PSf membranes was selected during two weeks. Thus, the manipulator makes it possible to significantly reduce the time of the new membrane preparation, reduce the volume of used polymer, and thus makes it promising to study expensive or new membrane materials.
