SCHMIDT’SCHE® PROCESS GAS COOLERS FOR STEAM REFORMING PROCESSES


Process gas coolers are installed at the end of steam reforming processes.The process gas leaving the reformer catalyst tubes and the secondary reformer enters the process gas cooler where saturated steam is produced on the shell side while cooling the gas in the process tubes. Process gas coolers operate in natural circulation and are connected to the steam drum via downcomers and risers where steam and water are separated. Depending on the process requirements, the gas downstream of the process gas cooler is used to superheat steam, preheat boiler feed water/feed or enters the CO-shift converter.

SCHMIDT’SCHE® PROCESS GAS COOLERS

Schmidt’sche® Process Gas Coolers withstand even extreme operation conditions and ensure safe operation of steam reforming plants. ARVOS’ engineers develop highly sophisticated designs that make the process gas coolers resistant to high temperatures and corrosion.

SCHMIDT'SCHE® PROCESS GAS COOLER DESIGN FEATURES ARE:

  • Fire tube design
  • Single-or twin-compartment design
  •  Refractory lined gas inlet chamber
  • Thin, flexible or super flexible tube sheets
  • Inlet tube sheet protected by ferrules and refractory lining
  • Full penetration, crevice-free tube to tube sheet welding to avoid crevice corrosion
  • Two bypass designs to control gas outlet temperature: a conventional “hot” bypass design or an improved “cold” bypass design for operation free of metal dust­ing
