Abstract
Processes for treating acid gas streams in a process for producing renewable transportation fuel are described. The H2S in the acid gas stream may be removed using one or more of adsorption processes, amine processes, scrubbing processes, and/or a neutralization processes. The acid gas stream with a reduced level of sulfur is thermally oxidized, and NOx is removed from the thermally oxidized stream.
Claims20
A process for treating an acid gas stream in a process for producing renewable transportation fuel comprising:
- removing H2S from the acid gas stream to form a second acid gas stream having a level of H2S lower than a level of H2S in the acid gas stream, wherein the H2S is removed using an adsorption process, an amine process, a scrubbing process, or a neutralization process;
- thermally oxidizing the second acid gas stream from the process for producing renewable transportation fuel in a thermal oxidation section comprising a thermal oxidizer to form a thermally oxidized stream;
- removing NOx from the thermally oxidized stream to form a treated outlet stream;
- and
- venting the treated outlet stream to the atmosphere.
A process for treating an acid gas stream in a process for producing renewable transportation fuel comprising:
- thermally oxidizing the acid gas stream from the process for producing renewable transportation fuel in a thermal oxidation section comprising a thermal oxidizer to form a thermally oxidized gas stream;
- removing H2S from the thermally oxidized gas stream to form a SOx treated gas stream having a level of H2S lower than a level of H2S in the acid gas stream;
- removing NOx from the SOx treated stream to form a NOx treated outlet stream having a level of NOx lower than a level of NOx in the SOx treated stream;
- and
- venting the NOx treated outlet stream to the atmosphere.
