How should sulfur vapor in the liquid sulfur tank be handled?
Thread Content
There is a large amount of steam in the liquid sulfur tank at our facility, which is released through the vent openings, causing significant environmental pollution. I’m not sure how others handle this situation; please give me some advice.
Liquid sulfur tanks usually contain some steam, but the amount is not large; this can be used to determine whether there is a leak in the jacket steam. By using its extractor, the air volume above the liquid sulfur tank can be reduced.
With such high temperatures in the liquid sulfur tank, it’s impossible to have no steam at all. But what explains the large amount of steam mentioned by the poster? It can’t be sulfur vapor, because the temperature in the liquid sulfur tank is only about 20°C higher than the freezing point of sulfur; whereas if it were water vapor, we have encountered such situations before. Although the temperature of water vapor is slightly higher than that of liquid sulfur, over time the vapor will condense into water at the top of the liquid sulfur tank and then return to the surface of the liquid sulfur, causing solidification on its surface. If the leak is not repaired as soon as possible, the area of solidified liquid sulfur will continue to increase.
Install an ejector and lead it to the burning furnace.
Such a large amount of steam could be due to a leak in the heating pipeline of the liquid sulfur tank. Normally, a steam ejector can be used to inject the steam from the sulfur tank into the incinerator for combustion.
I was wondering, are the air pumps you use good? The air pump in our office doesn’t work well. Could you introduce your air extraction process?
Install a steam ejector to draw the sulfur vapor and hydrogen sulfide from the liquid sulfur tank into the flue gas incinerator for combustion.

Pneumatic sampler, H2S concentration around 200PPM
The air extractor in our unit doesn’t seem to work very well. What is the diameter of the tubing used in your air extractors?
The gas pumps for sulfur plants aren’t very reliable. There’s a lot of steam coming out; there’s no doubt that there’s a leak, and it can’t be the heating pipe beneath the liquid sulfur. We have carried out several inspections over the past two years, and through actual observation, the heat tracing pipes submerged in liquid sulfur show almost no corrosion; the actual areas where corrosion occurred were the pipes near the inlet of the gas extractor, where corrosion led to perforations. I have photos here; those who are interested can communicate.
