Sulphur Condensers
Altex’s Sulphur Condensers are expertly engineered to efficiently recover sulfur from process gas streams while maximizing heat transfer and reliability. Designed for demanding industrial environments, our condensers ensure optimal performance and longevity.
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, ensuring efficient heat recovery.
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.
