Sulfur Trap

A method of separating liquid sulfur from a process stream containing liquid sulfur and gases, comprising:

• providing a said sulfur trap comprising:
• a chamber;
• a chamber fluid inlet;
• a chamber gas outlet;
• a chamber liquid outlet;
• and
• a chamber liquid level control system;
• wherein:
• said chamber liquid outlet is disposed below said chamber fluid inlet and said chamber gas outlet;
• said chamber liquid outlet comprises a discharge orifice;
• and
• said chamber liquid level control system comprises:
• a float;
• a fulcrum;
• a nozzle insert;
• and
• a lever comprising a float end and a nozzle insert end;
• wherein:
• said lever is pivotally connected to said fulcrum intermediate said float end and said nozzle insert end;
• said float is attached to said lever float end;
• said nozzle insert is attached to said lever nozzle insert end;
• rise of said float raises said lever float end and lowers said nozzle insert end via pivoting of said lever about said fulcrum;
• fall of said float lowers said lever float end and raises said nozzle insert end via pivoting of said lever about said fulcrum;
• said chamber liquid level control system operates to engage said nozzle insert with said discharge orifice, via upward bias of said nozzle insert toward said discharge orifice, when a level of a liquid within said chamber is below a desired height, to prevent fluid flow out of said chamber liquid outlet via said discharge orifice;
• and
• said chamber liquid level control system operates to disengage said nozzle insert from said discharge orifice, via downward bias of said nozzle insert away from said discharge orifice, when said level of said liquid within said chamber is above a desired height, to allow gravitational flow of at least a portion of said liquid out of said chamber liquid outlet via said discharge orifice;
• and
• introducing a fluid flow of said process stream into said sulfur trap.
