The cation exchange chromatographic separation of pyridine, monoethanol amine (MEA) and triethanol amine (TEA) have been explored from source to receiving phase through a fiber supported solid membrane (FSSM). The FSSM were prepared by chemical modification of cellulose fibers with introducing the carboxylic acid ion exchanging groups. The experimental values explored were concentration of pyri...

Abstract. Natural gases containing impurities, namely carbon dioxide (CO2), heavy hydrocarbons, hydrogen sulfide (H2S), and water vapour, need treatment for removing acidic (CO2 H2S) to reduce corrosion enhance the heat capacity of gas. This gas is commercially known as "sour", typically, sour any that contains significant levels sulfide. The presence can affect natural quality, which also lead...

A 30% aqueous solution of waste methyldiethanolamine (MDEA) can be regenerated, reused in gas treatment, and its residue used as a secondary raw material another area production. (HOCH 2 CH ) NСH 3 is separated from water by vacuum-extraction method. MDEA destroyed part remain the column. In laboratory conditions, it was shown that degree purification destruction products this method 60 to 78%....

In this work, a mathematical model is established to describe the removal of CO2 from gaseous mixtures including CH4 and CO2 in a polypropylene hollow fiber membrane contactor in the presence of conventional absorbents such as monoethanolamine (MEA), methyldiethanolamine (MDEA), and a blend of them. Modeling was performed in axial and radial directions under the fully-wet condition for counterc...

Chemical absorption of CO2 into aqueous amine solutions using a nonstirred bubble column was experimentally investigated. The performance four different primary and secondary amines including monoethanolamine (MEA), piperazine (PZ), 2-piperidineethanol (2PE), homopiperazine (HPZ) were compared. effects initial concentration amine, the inlet mole fraction CO2, solution temperature on rate loadin...

density, viscosity and refractive index of pure, binary and ternary mixtures of diethanolamine (dea) and methyl diethanolamine (mdea) with water have been measured at different temperatures from 288.15 k to 323.15 k at atmospheric pressure. also, this study presents the effects of mixture composition and temperature upon these thermo- physical properties. to measure the density and refractive i...

the equilibrium solubility data of co2 in the various aqueous blends of triisopropanolamine (tipa) + monoethanolamine (mea) with the total alkanolamine concentration of 2 mole / dm3 were measured at the temperatures of 30, 40, 50, 60 and 70 oc and co2 partial pressures below 100 kpa. the experiments were done in an atmospheric gas absorption system and the amount of absorbed co2 was measured wi...
