Sulfur-bearing residue treatment system

A process for stripping organics from a sulfur-bearing residue stream comprising:

• a) conveying a liquid, organics-containing, sulfur-bearing residue stream to a stripping zone,
• b) stripping the liquid, organics-containing, sulfur-bearing residue stream, in the stripping zone, to form a vapor stream containing organics and a liquid residue stream,
• c) conveying the liquid residue stream to a lower flash zone, and
• d) indirectly heating the contents of the lower flash zone to flash vaporize the contents of the lower flash zone into a lower flash zone vapor stream and a lower flash zone liquid residue stream.

A process for stripping organics from a sulfur-bearing residue stream comprising:

• (a) conveying a liquid, organics-containing, sulfur-bearing residue stream to a stripping zone;
• (b) in the stripping zone, stripping the liquid, organics-containing, sulfur-bearing residue stream to form a vapor stream containing organics and a liquid residue stream;
• (c) conveying the liquid residue stream to a lower flash zone;
• (d) in the lower flash zone, flash vaporizing the liquid residue stream into a lower flash zone vapor stream and a lower flash zone liquid residue stream;
• (e) withdrawing the lower flash zone liquid residue stream from the lower flash zone and separating the lower flash zone liquid residue stream into a first portion and a second portion;
• and
• (f) indirectly heating the first portion of the lower flash zone liquid residue stream and returning the heated first portion of the lower flash zone liquid residue stream to the lower flash zone.
