Total sulfur in propylene
Thread Content
The total sulfur content in the propylene that has been purified through catalysis is around 20 ppm, while it remains at 10 ppm in the propylene obtained from the gas separation process. I would like to know what the reasons for this are. Additionally, how can the desulfurization system for liquefied gas be adjusted?
Propylene can only be separated through gas separation; catalytic processes produce liquefied gas that contains propylene. Therefore, the claim that \"the total sulfur content in propylene obtained through catalytic refining is around 20 ppm\" is incorrect
Around 20 is considered high; my previous readings were always below 1. Now they’re two or three, and there’s no hydrogen sulfide either – it’s difficult to get control of the situation. It is said to be hydroxysulfur
The total sulfur content in our liquefied gas is around 20 PPm, while that in the propylene produced is 1 PPm; no efforts are made to control the total sulfur content in the propylene

Carbonyl sulfide can be removed by adsorption using adsorbents.
