Sulphur Condensers
It doesn’t matter how you spell it, sulphur or sulfur, we’ll make it condense!
Modern sulphur trains typically have five (5) sulphur condensers with four (4) reheater exchangers in between stages.
The Claus Process
Sulphur Condensers are a special category of shell & tube heat exchangers and are used in Sulphur Recovery Units (SRU) in refinery or gas plants.The Claus Process (Reaction) occurs to strip out and convert hydrogen-sulphide into elemental sulphur, greatly reducing the environmental, safety, and material hazards associated with H2S.
Altex designs and fabricate Sulphur Condensers to ASME VIII-Div.1 and ASME I Codes, utilizing UHX or FEA for tubesheet design.
Scope of Supply:
- Thermal and hydraulic guarantees
- Mechanical guarantee
- Finite Element Analysis (FEA)
- Sulphur drains
- Demisters
- Spargers
- Refractory – brick and castable
- Tube ferrules
- Insulation
Construction:
- Carbon Steel with SA-179 or SA-192 tubes typically.
- Weld-overlay and cladding available
- Strength-welded tube-tubesheet joints
- Inner-bore welded tube-tubesheet joints (cold side of tubesheet, can be radiographed)
- UHX or ASME I flexible “knuckle” style tubesheets
- 1% slope typical
Engineering & Design:
- ASME Section I and Section VIII-Div.1
- Typically, non-code tubeside
