Abstract
A reactor system can include a reactor, including: a first inlet for a first stream including a liquid sulfur including a dissolved hydrogen sulfide, a polysulfide, or a combination thereof. A second inlet can be for a second stream, wherein the second stream can be an oxygen-containing gas with no more than about 2%, by weight nitrogen. A packing can be in contact with a catalyst.
Claims20
A reactor system, comprising:
- a reactor, comprising:
- a first inlet for a first stream including a liquid sulfur comprising a dissolved hydrogen sulfide, a polysulfide, or a combination thereof;
- a second inlet for a second stream;
- the second stream, wherein the second stream is an oxygen-containing gas with about 0.0001% to about 2%, by weight, nitrogen;
- a packing in contact with a catalyst;
- a sulfur recovery zone;
- a tail gas treatment zone;
- and
- a carbon dioxide conditioning zone,
- wherein the reactor is configured to generate an off-gas stream passed to the sulfur recovery zone,
- wherein the sulfur recovery zone is configured to generate a tail gas stream passed to the tail gas treatment zone,
- wherein the tail gas treatment zone is configured to generate a treated tail gas stream comprising carbon dioxide and water passed to the carbon dioxide conditioning zone to produce a stream comprising carbon dioxide,
- wherein the stream comprising carbon dioxide provided to the second inlet, and
- wherein the second stream comprises a stream comprising carbon dioxide from the carbon dioxide conditioning zone and a stream comprising oxygen from the sulfur recovery zone.

A system for degassing a liquid sulfur, comprising:
- a zone configured to receive a stream comprising oxygen and a stream comprising an acid gas to produce a stream comprising a liquid sulfur;
- a reactor system comprising a first inlet for a first stream including the liquid sulfur comprising a dissolved hydrogen sulfide, a polysulfide, or a combination thereof, and a second inlet for a second stream of an oxygen-containing gas with about 0.0001% to about 2%, by weight, nitrogen;
- a carbon dioxide conditioning zone configured to receive a treated tail gas stream,
- wherein the reactor system is configured to generate an off-gas stream passed to the zone,
- wherein the zone is configured to generate a tail gas stream passed to a tail gas treatment zone,
- wherein the tail gas treatment zone is configured to generate the treated tail gas stream comprising carbon dioxide and water passed to the carbon dioxide conditioning zone to produce a stream comprising carbon dioxide, and
- wherein the stream comprising carbon dioxide provided to the second inlet.
