Methyldiethanolamine, also known as N-methyl diethanolamine and more commonly as MDEA, is the organic compound with the formula CH 3 N(C 2 H 4 OH) 2. It is a colorless liquid with an ammonia odor. It is miscible with water, ethanol and benzene.

The sweetening chemical selected for the Forestburg Plant was methyldiethanolamine (MDEA). This was chosen due to its capability to remove H2S and leave a portion of the CO in the residue gas. At the time of plant 2 commissioning it was one of the first operating MDEA facilities in Western Canada.

2023年11月1日 · 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.

2021年12月15日 · We propose a modified process configuration for an MDEA-based CO 2 capture unit for low-carbon H 2 production via steam methane reforming of natural gas. The optimal set of operating conditions that minimizes the energy consumption of the process while maximizing the CO 2 capture rate are found by solving a multi-objective optimization problem.

Figure 1 shows a simplified process flow diagram (PFD) of a typical methyl diethanolamine (MDEA)-based acid gas removal (AGR) process. It shows the typical process arrangement of chemical absorption processes, with acid gas in countercurrent flow with solvent in the trayed absorber column.

The use of MDEA and mixtures of amines for bulk CO 2 removal is explored using three cases with CO 2 levels ranging from about 3-15%. MDEA is compared to MEA, DEA, and DGA for a base set of conditions for bulk CO 2 removal. The effect of the most important operating parameters on the performance of a unit using MDEA based solvent is also explored.
