    H2S corrosion at >420 °C, materials of construction

    The reactors are short distillation columns, so cannot be made from refractory lining. Carbon steel would probably corrode rapidly and would need to be replaced every 3 to 5 years (or less??) I think probably SS310 or something similar, but I have no real idea. Just curious about what steel is...

    H2S corrosion at >420 °C, materials of construction

    thread124-422341 I read the above old thread and looked into the links for the Unitel and JGC H2S processes and found out that H2 is reacted with molten sulfur at >420 °C. I am curious to know what type of steel is used for the reactor, because I can't imagine normal stainless steels are...

    Discharge pressure of a liquid ring compressor?

    Thanks for your advice. But maybe I didn't make myself clear enough. As I mentioned before, I want to compress a gas from about 10 bar to 25 bar. I thought maybe I can use a liquid ring compressor to achieve this, because there's an issue with regards to the leakage of the process gas. From what...

    Discharge pressure of a liquid ring compressor?

    I know that a LRC can compress a stream up to 15 bar, but is this the differential pressure or the absolute discharge pressure? I’m asking because I would like to compress a gas stream from 10 bar to 25 bar. Would appreciate any feedback.

    Sulfur Aerosol - Formation and Elimination?

    Hello, I would like to know if the someone has experience of sulfur aerosols. I'm looking to regenerate a catalyst (340 °C) whereby sulfur is formed (ca. 3 wt% in gas). If I were to quench the hot gas with water, I assume sulfur aerosol will be formed. Does anyone know to what extent? How best...
