Will the low water vapor ratio conversion process have an impact on low methane levels?
Thread Content
As the title suggests, does anyone who knows about this exist? It is said that in Baofeng, Ningxia, the low water-to-gas ratio shift process used by Ningxia Coal results in excessive total sulfur levels in the low-temperature methanol washing process, with impurities such as thiols present in the shifted gas. Those who know about this, please share the information!
Are you referring to Ningmei’s coal-to-oil project, or its olefin production?
That can’t be possible; it must be due to the quality of the coal? Besides, there are many reasons for the excessive total sulfur level
It seems that the total sulfur content in the purified gas from the methanol plant in Baofeng, Ningxia is above the specified limit; the exact details are not clear
I’ve verified it; it’s Ningmei coal-to-oil
Everyone who’s an expert, come on! Does anyone know anything about this?
Low water-gas ratio conversion has many disadvantages. One of these disadvantages is that during this process, methanation reactions tend to occur; methanation reactions result in the formation of methyl-bound hydrogen, which subsequently leads to the production of methane； At the same time, the generated methyl groups tend to combine with sulfur to form compounds such as thioalcohols and thioethers, which have a significant impact on subsequent low-methane washing processes.
A low water vapor ratio is still not mature; many design institutes have given up on using such designs nowadays.
