MDEA Desulfurization Technology Process
MDEA desulfurization technology process: The natural gas and MDEA solution are convectively contacted by using an absorption tower. At this time, the MDEA solution absorbs most of the hydrogen sulfide, and the purified gas is discharged from the upper part. The H2S-rich solution flowing out of the bottom of the tower is first flashed and depressurized, and then the heat in the solution is recovered through the poor-rich solution heat exchanger and then enters the regeneration tower for regeneration. After the temperature of the lean solution is lowered, it is pressurized by a circulating pump After entering the absorption tower to complete the cycle.
Prospect of MDEA desulfurization technology
At present, the MDEA desulfurization technology also has the following problems: first, the selective adsorption capacity of the MDEA system is not strong; second, how to remove organic sulfur; third, there is a foaming problem in the MDEA system during the production process. Some domestic scholars and professors should start from the perspective of industrial application to solve these problems. Make the natural gas MDEA desulfurization method more perfect. It can further reduce its production cost, improve the economic benefits of the natural gas industry, and contribute to our economic development.
