Establishment of sulfur seal tank level

When the Klaus sulfur unit is started up, there is no sulfur seal in each sulfur sealing tank; once the sulfur discharge valves are opened, it is easy for the process gas to pass through these tanks and reach the liquid sulfur tank, thereby spreading throughout the area and posing a risk to personnel safety. At present, how do you establish the liquid level in these sulfur sealing tanks during startup, in order to minimize the influence of factors such as human experience?
The conventional approach is to buy sulfur, add it inside, and create a sulfur seal after it melts.
Usually, we buy some sulfur; we have always directly created sulfur seals.
How long does it generally take to melt?
The melting of sulfur depends on the type of steam you use. Within 6 hours. It is also possible to close the jacket valve for liquid sulfur before starting the vehicle, and then gradually open the liquid sulfur valve once it is running, allowing the liquid sulfur level to be established on its own; this is a more convenient approach. Do you need driving directions? I can provide it
Previously, we also used liquid sulfur valves for indirect switching, relying on the liquid sulfur generated by the system to create a sulfur seal; however, we now consider this method to be too risky, and plan to use melted solid sulfur to establish the sulfur seal. I want to know how long it takes to melt solid sulfur particles using heating with a 0.4Mpa steam jacket, for about 100 kilograms of sulfur.
Once you become proficient at it, that’s fine; I’ve operated several sulfur recovery systems in the same way.
Basically, this process relies entirely on experience. I would like to know if there are any methods for monitoring whether a liquid seal has been established in the sulfur-sealing tubes, such as using diaphragm pressure gauges or something similar.
It is safer to use melted sulfur to establish the liquid level. The minimum sulfur seal height is calculated based on the system pressure and the density of liquid sulfur, which is around 1.8; thereafter, the amount of solid sulfur that needs to be added is determined based on the size of the sulfur seal tank. Our experiments show that melting sulfur one day in advance can meet the system’s requirements; this is of course based on factors such as the actual amount of sulfur added, its bulk density, and the heat load.
