How the PGC Gas Cooler Works

The most commonly used PGC gas cooler is the transverse tube (cross-flow) type, featuring:

• A vertical rectangular housing, typically around 30 meters tall

• Multiple horizontal cooling pipes, installed at a 3° angle for efficient drainage

• A two-stage cooling system, with:

  • Upper section using cooling water at 25–32°C

  • Lower section using water at 18–25°C

• Hot gas enters from the top, flows downward outside the tubes

• Cooling water flows inside the tubes, absorbing heat in counterflow

• An ammonia water spray at the top helps dissolve condensed crystals, preventing clogging and fouling

The result is a stable outlet gas temperature that meets technical requirements for downstream processing.
