Questions regarding the liquid sulfur tank cover plate
Thread Content
I’d like to ask everyone how you design the covers for liquid sulfur tanks. The challenge we face is that the pipelines need to pass through the cover plates. If ordinary sleeves are used, could hydrogen sulfide leak out? If the sleeves are welded to the process pipelines, the high temperature from those pipelines will be transmitted to the concrete cover plates, whereas concrete cover plates can only withstand temperatures of around 70 degrees Celsius at most, so this is not acceptable. So, how do the sailors here handle this? Could you share some experience with pictures?
The inflow and outflow of steam and condensate water occur through pre-installed conduit pipes. The inlet and outlet of the other jacket pipes are through metal covers. A normal liquid sulfur tank is maintained at a slight negative pressure using a steam ejector.
Isn’t the liquid sulfur tank in a slightly negative pressure environment? A metal cover can be used, and no hydrogen sulfide will be released
