Nov 1, 2023 · Drawing inspiration from the advantages of MDEA in CO 2 capture, a promising technique is proposed for sequestering more CO 2 in cement-based materials. This study presents the novel idea of utilizing buildings and infrastructures made of cement-based materials with MDEA as “synthetic trees” that can collect CO 2 from the environment.

In the past 10 years, numerous plants have been built or converted to methyldiethanolamine (MDEA) to take advantage of its selective absorption capability. In selective absorption, the H2S is selectively absorbed from the gas leaving large amounts of CO2 in the gas.

Oct 1, 2024 · Study on the absorption and desorption performance of MDEA compound solution. Effect of multiple accelerators on desorption efficiency. Evaluation of performance under low-temperature desorption conditions. Propose optimized ratios at specific concentrations. The global climate change problem has brought much attention to CO 2 capture technology.

Dec 15, 2021 · We propose a modified version of the standard MDEA-based CO 2 capture process flowsheet, and we optimize the operating conditions by solving a multi-objective optimization problem to minimize energy consumption while maximizing the CO 2 capture rate.

Jan 29, 2021 · Porous hollow fibres made of polyvinylidene fluoride were employed as membrane contactor for carbon dioxide (CO 2) absorption in a gas–liquid mode with methyldiethanolamine (MDEA) based...

Jul 13, 2020 · In the present study, calorimetric measurements were conducted to determine CO 2 behavior in aqueous solutions of 30 and 50 wt % N-methyl diethanolamine (MDEA) and 40 + 10 wt % MDEA–piperazine (PZ) at 323.15 and 353.15 K at pressures from 0.5 to 4 MPa.

Jun 28, 2016 · In the present study, results from three different CO 2 capture experimental scales (laboratory, pilot unit, and a larger pilot unit), using aqueous amine solutions of methyldiethanolamine (MDEA) 20 wt %, are compared in terms of loading capacity.

In this study, blended solutions of methyldiethanolamine (MDEA) with piperazine (PZ) are used due to its higher CO2 capacity, low vapor pressure, thermal stability and less significant corrosive nature [5, 7]. MDEA is a tertiary amine and has a low reaction rate to CO2.

Oct 15, 2020 · A piperazine (PZ)-promoted methyldiethanolamine (MDEA) solution for a carbon dioxide (CO 2) removal process from the flue gas of a large-scale coal power plant has been simulated. An Aspen Plus ® was used to perform the simulation process.

Aug 5, 2010 · In this study, we use the Electrolyte Nonrandom Two-Liquid activity coefficient model to develop a rigorous and thermodynamically consistent representation for the MDEA−H 2 O−CO 2 system.
