Heat exchanger for propane dehydrogenation (PDH) units using UOP technology, engineered to operate under large temperature differences, fatigue loading and stress‑corrosion conditions.
Information
Service conditions: large temperature gradients, cyclic (fatigue) loads, environments prone to stress‑corrosion.
Construction: butt welding on tubes to tube‑sheet joints to maintain integrity under critical conditions.
Function
Heat transfer between process streams in PDH units
Temperature control of propane feed and product streams
Energy recovery and integration with reactor/separation units
Capacity Range
Applicable to PDH projects up to 450,000 tpy (project dependent)
Custom designs available for other capacities
Driving Sources
Steam
Thermal oil / hot oil
Process gases and flue gases
