RE: Sulfur Trap
Normal function is to adsorb the sulphur specie to the metal which could be e.g. Zn,Ni,Cu.
For lighter feedstocks high temperature (300-400°C)adsorption (ZnO) is usually used like the ones in a H2 plant. Get into contact with a licensor for H2 plants and they can help you.
FOr sulphur traps for Isomerisation units or cat.reformers usually NiO or CuO based materails are used. These can operate at a lower temperature e.g. 130 °C, companies like UOP can assist you with these kind of sulhur traps.
RE: Sulfur Trap
This sulfur trap is needed for a Sulfur Recovery Unit where liquid sulfur will be removed through a Sulfur Trap and then passes to the Sulfur Storage Tank
Any suggestions
Thanks & Regards

RE: Sulfur Trap
GPSA recommends that a Seal Leg be designed to withstand the air blower maximum discharge pressure plus an additional 6" to 12" safety factor for transients, with a minimum Seal Leg depth being 13 ft.
Typically, the process side of SRUs are designed for a pressure of 15 psig. Using the density of liquid sulphur at process tmeperature, this is equivalent to a seal leg depth of ~11.5 ft.
To determine the pressure rating of your seal leg, look at the mechanical drawings to get the depth. Convert the depth to psi using the density of liquid sulphur at process temperature.
Hope this helps, Brian
