The most common method of recovering sulphur from natural
gas is the Claus process. To simulate the Claus process, I use Sulsim.
This simulator enables one to design multistage Claus Processes to meet
the various requirements needed to meet environmental specifications.
Shown here are simple two-stage Claus plants for 1 to 10 Tons
of Sulphur removal. Plants, up to 20 tons, can be skid mounted packages.
Larger plants, or plants requiring a higher level of sulphur removal,
are normally grass roots facilities.
