ABSTRACT:
A compact, tiered sulfur recovery unit having a burner, a combustion chamber, a reaction chamber, a waste heat boiler and a steam drum. The waste heat boiler is mounted above the reaction chamber, and the steam drum is mounted above the waste heat boiler, resulting in a three-tiered, compact design, requiring only a single platform for space. The reaction chamber comprises a horizontal body and an upright plenum. The reaction chamber includes an inlet for receipt of acid gas (H2S). One end of the horizontal body of the reaction chamber is fluidly attached to the combustion chamber, while the other end of the horizontal body of the reaction chamber is fluidly attached to a lower end of the upright plenum of the reaction chamber. An upper end of the upright plenum of the reaction chamber is fluidly attached to the waste heat boiler. The waste heat boiler includes an outlet for the release of SO2for downstream sulfur blowdown to produce additional elemental sulfur. The waste heat boiler is fluidly attached to the steam drum.
