Refining gas and natural gas desulfurization
Thread Content
Do domestic refineries use diisopropanolamine for refining gas desulfurization? Has this method been eliminated?
I heard that there are only a few companies that still retain this kind of craftsmanship, but I don’t know exactly which ones.
MDEA is commonly used, which is stable, effective, good in analytical performance, low in energy consumption, less corrosive but prone to foaming.
I heard that TIPA was used in the past, but now almost everyone has changed the process to MDET. It seems that this is a trend.
Most of the solvents used for desulfurization now are MDEA. The effect is relatively good. The so-called high quality and low price. 1#swj_014
