It doesn’t matter how you spell it, sulphur or sulfur, we’ll make it condense!
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.
Modern sulphur trains typically have five (5) sulphur condensers with four (4) reheater exchangers in between stages.
Altex designs and fabricate Sulphur Condensers to ASME VIII-Div.1 and ASME I Codes, utilizing UHX or FEA for tubesheet design.
Waste Heat Boilers
Big and Ugly.
Waste Heat Boilers are a critical component in Waste Heat Recovery Systems and must be suitable to resist inlet gas temperatures exceeding 2600°F. Refractory lining and tubesheet design are critical in ensuring metal temperatures and stresses do not exceed Code and design limits.
Altex designs and fabricate Waste Heat Boilers to ASME VIII-Div.1 and ASME I Codes. FEA can be used in some cases for non-UHX tubesheet design, complicated geometries, and extreme temperature gradients.
