Abstract
Aspects of this disclosure enhance elimination problems that freezing sulfur creates with gas-liquid parallel plate separators by integrally heating the parallel plate gas-liquid separator assembly. Through integral heating the duration of time that the separator apparatus remains above the freezing temperature of elemental sulfur is prolonged, thereby, allowing the opportunity for residual liquid sulfur to drain from the parallel plate assembly during upsets in unit operations and after a sulfur recovery unit shutdown event, thereby reducing or eliminating the operation and maintenance problems that may occur with existing separator designs.
Claims20
A heated entrained sulfur removal element, comprising:
- a support frame, comprising opposing end plates;
- a thermally conductive plate located between said opposing end plates and coupled to said support frame;
- at least one heating element that extends through said thermally conductive plate and said opposing end plates, said heating element having connectors located on ends thereof configured to couple said ends of said heating element to a heating source;
- and
- at least one tie rod that extends through said opposing end plates and said thermally conductive plate and binds said thermally conductive plate to said support frame.
A sulfur recovery system, comprising:
- a sulfur recovery unit combustion and thermal reactor connectable to a sulfur gas feed line;
- a waste heat recovery unit coupled to said sulfur recovery unit combustion and thermal reactor;
- a first sulfur condenser heat exchanger coupled to said waste heat recovery unit and further being coupled to a first heating media supply and a first heating media return and a process gas heater coupled to a catalytic reactor;
- a second sulfur condenser heat exchanger coupled to said catalytic reactor and to a second heating media and a second heating return and further being coupled to a sulfur tail gas unit;
- a heated entrained sulfur removal element coupled to at least one of said first sulfur condenser heat exchanger or said second sulfur condenser heat exchanger, comprising;
- a support frame, comprising opposing end plates;
- a thermally conductive plate located between said opposing end plates and coupled to said support frame;
- and
- at least one heating element that extends through said thermally conductive plate and said opposing end plates, said heating element having connectors located on ends thereof configured to couple said ends of said heating element to a heating source.
