A synthetic method has been used to measure the bubble-point pressures of carbon dioxide (CO2) and methane (CH4), for a temperature range 303.15–363.15 K up 14 MPa, in following ionic liquids: 1-ethyl-3-methylimidazolium diethylphosphate [emim][dep], trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl)phosphinate [thtdp][phos], dicyanamide [thtdp][dca], 1-allyl-3-methylimidazolium [amim][dca], 1-butyl-1-methylpyrrolidinium [bmpyrr][dca], 1,2,3-tris(diethylamino)cyclopropenylium...
Gas-liquid membrane contactors that were based on hollow fiber membranes are the example of highly effective hybrid separation processes in field technology. Membranes provide a fixed and well-determined interface for gas/liquid mass transfer without dispensing one phase into another while their structure (hollow fiber) offers very large surface area per apparatus volume resulted compactness modularity equipment. In many cases, stated benefits complemented with high selectivity typical...
In the development of composite gas separation membranes for post-combustion CO2 capture, little attention is focused on optimization membrane supports, which satisfy conditions this technology. The primary requirements to supports are concerned with their high permeance. work, desired characteristics were developed as high-permeance thin film (TFC) defect-free layer from crosslinked highly permeable polymer, poly[1-(trimethylsilyl)-1-propyne] (PTMSP). This insoluble in chloroform and can be...
Abstract The ductility of a calcium carbonate‐filled amorphous copolyester PETG in uniaxial tensite test was examined as fiction other filler volume fraction. A ductile‐to‐quasibrittle transition occurred the fraction increased. This from propragation stable neck through entire gauge length specimen to fracture without propagation. draw stress (lower yield stress) did not depend on content and equal unfilled polymer. It therefore possible use simply model predict dependence strain proposed...
In this work, perspective polymeric materials were developed for membrane contactor applications, e.g., the dissolved oxygen removal from amine CO2 capture solvents. Several blends based on poly[1-trimethylsilyl-1-propyne] (PTMSP) and poly[vinyltrimethylsilane] (PVTMS) studied. The gas water vapor sorption permeability coefficients PTMSP/PVTMS blend membranes at different PVTMS contents (0–100%) obtained under temperatures of 30 60 °C first time. As content increases, O2 permeabilities...
Multiple cracking of a thin platinum film deposited on polyethylene terephtalate, isoprene rubber, and natural rubber substrates under tensile deformation was studied by light scanning electron microscopy. The cover fractures several fragments elongated in the direction perpendicular to loading direction. width fractured depends thickness layer applied stress. A semiempirical equation describing average obtained. Appearance wavy pattern an originally smooth surface composites with rubberlike...
For the development of high efficiency porous supports for composite membrane preparation, polysulfone (PSf) hollow fiber membranes (outer diameter 1.57 mm, inner 1.12 mm) were modified by air plasma using low temperature treatment pilot plant which is easily scalable to industrial level and Piranha etch (H2O2 + H2SO4). Chemical modification affected only surface layers did not cause PSf chemical structure change. The modifications led roughness decrease, great importance further thin film...
Abstract The effect of rigid particles on the fracture mode polymers that yield with necking was analyzed theoretically a model regularly arrayed spherical particles. adhesion between polymer and assumed to be weak, were debond from before necking. A linear decrease in engineering draw stress an increase filler content derived. An leads transition deformation mechanism. depends ability strain‐harden. If strain‐harden is insignificant (strenght) lower than its stress, ductile brittle...
Heat-stable salts (HSS) are well-known degradation products in the acid gas removal technologies with alkanolamines, especially post-combustion CO2 Capture processes. The traditionally applied HSS methods such as purging, filtration, distillation might be economically unattractive large scale plant case. Electrodialysis could an alternative method for solvent reclaiming of electrically charged amine products. This work presents results electrodialysis concept tested under real operation...
Heat-stable salts (HSS) in amine-based solvents may lead to a long-term performance impairment of post-combustion CO2- capture process system. They can cause loss solvent capacity, corrosion, heat exchanger fouling, increased foaming or flooding, etc. The application electrodialysis (ED) be possible cost effective technique for removal HSS from degraded amine solutions. paper presents the results lab-scale ED experiments on synthetic MEA solutions with different content and CO2-loadings....
Heat stable salts (HSS) formed and continuously accumulated in the amine-based solvents due to solvent degradation impurities feed gas can dramatically change efficiency of amine scrubbing process. HSS be removed by using different methods including membrane separation such as electrodialysis (ED).
