To achieve the CO2 emission control as urgent task of Carbon Peak and Neutrality, desorption experiments were performed with a new tri-solvent MEA-EAE(2-(ethylamino)ethanol)-DEEA(N, N-diethylethanolamine) five solid acid catalysts: blended catalysts γ-Al2O3/H-ZSM-5 = 2:1, H-Beta (Hβ), H-mordenite, HND-8, HND-580 H2SO4 replacement. A series sets in typical recirculation process by means both hea...

CO2 removal by the blended amine solution of piperazine (PZ) and methyldiethanolamine (MDEA) with various molar concentration ratios in a rotating packed bed (RPB) was modelled using MATLAB linked to Aspen Plus. All required correlations for RPB addition mass energy balances were written while demanded physical transport properties extracted from The similar operating conditions compositions re...

The elimination of impurities from natural gas (water, CO2, H2S, mercaptans) is an obligation: in Europe, a max. 20 mg/Sm3 total sulfur (at 15°C and 1 atm) allowed, as well 2.5 vol% CO2. It maximizes the calorific value delivered limits chemical risks (corrosion, toxicity) associated with this transition fuel to cleaner energy sources. Acid separation commonly performed by reactive gas-liquid a...

It is well known that small amount Piperazine (PZ) enhance the CO2 absorption properties of tertiary amine aqueous solution. Because the tert-amine has the lower heat of reaction, the blended amine solution, tert-amine with PZ, is attractive for low energy absorbent. There are some reports about the investigation of the mechanism of the blended amine solution, however, there still a difficulty ...

Carbon capture technologies have been recognized as a potential alternative to alleviate global warming. and storage (CCS) is preferred over carbon conversion utilization (CCU) due its lower operating costs higher CO2 reduction capability. Nevertheless, has the be more economical if value-added products are produced. This highlights importance of assessing routes alternatives in management. rev...

the object of this work is solubility correlation and prediction of co2 and h2s in various aqueous alkanolamines using the electrolyte cubic square-well equation of state (ecsw eos) [haghtalab, a.,mazloumi, s. h., (2009a), fluid phase equilib.,285,96-104]. the eeos systematically is applied to describe the solubility of acid gases in various alkanolamine solutions, including mdea, mea, dea, amp...

A reaction calorimeter was used to study the rate and heat effects during CO2 absorption into aqueous solutions of N-methyldiethanolamine (MDEA). The experiments were carried out at constant pressure of 0.1 MPa and 0.3 MPa over a range of temperature from 293 K to 333 K. The amine content changed from 10 to 30 mass %. The experimental equipment and procedure were described with the emphasis on ...

The present research provides data on the density (ρ), viscosity (η) and ability to absorb carbon dioxide of systems containing amine, molecular solvent (MS) choline chloride (ChCl), with investigation physical properties both neat amine/MS/ChCl mixtures their samples after complete CO2 saturation. effect mixture composition was studied by varying amine from primary (monoethanolamine, MEA) seco...
