What is the appropriate temperature for liquid sulfur?
It is usually heated with steam at 0.3 MPa; the actual temperature of liquid sulfur is around 140 degrees Celsius, and it will condense if the temperature drops below 121 degrees.
130–160°C is appropriate; beyond this range, the fluidity of liquid sulfur deteriorates.
135-145 is the optimal range; too high a value can lead to ignition over time, while too low a value can cause gradual solidification in certain areas.
130 to 160 is the most suitable
130-160, 0.3 MPa steam tracing is just right
We keep it between 130 and 150 here; there should be no major issues. It’s mainly set based on the viscosity-temperature properties of liquid sulfur!
The viscosity of liquid sulfur varies with temperature； 119-190 has high viscosity, 190-232 has better stability; the higher the temperature above 232, the better the fluidity
The normal storage temperature for liquid sulfur is around 150°C, as this is when its viscosity is at its lowest. At temperatures above 150°C and below 320°C, liquid sulfur has very high viscosity. When the temperature is above 320°C, its viscosity drops back to around that of 150°C.
Liquid sulfur pipelines are generally heated using steam at 0.3 MPa; the optimal temperature range is around 140–160 degrees Celsius. If the temperature is too low, the sulfur tends to solidify and block the pipes. The viscosity is highest at around 190°C, resulting in poor fluidity.
We control the steam heat supply to maintain the liquid sulfur temperature between 130 and 135 degrees, ensuring good fluidity of the liquid sulfur while saving energy.
