There is an electrical heating sulfur pipeline with a length of 2000 meter in this refinery.
The power supply of the heating system abnomally turned off for 4 days.
The liquid sulfur solidified during this period.
The power supply of the heating system then automatically turned on at the beginning the 5th day.
At the 8th day, the sulfur pipeline rupture at three locations.
As we know, Remelting of sulfur will increase the specific volumn and cause overpressure in the pipeline.
Can any expert in this field teach us how to do the remelting procedure?
The electrical heating system of this sulfur pipeline is skin effect type.
