What Is a PGC?

A Primary Gas Cooler (PGC) is a critical piece of equipment used to cool high-temperature raw coke oven gas before it enters the next stages of purification. This process protects downstream equipment, facilitates tar and ammonia recovery, and enhances overall system safety and efficiency.

The most widely used structure is the transverse tube type, featuring:

• A tall vertical housing (typically ~30 meters)

• Horizontal cooling pipes installed with a 3° downward slope

• Two-section water cooling system:

  • 25–32°C water in the upper section

  • 18–25°C water in the lower section

• Ammonia water sprayed from the top to dissolve condensed crystals and prevent clogging

• Gas enters from the top and exits from the bottom, in countercurrent to the cooling water

PGCs are essential in maintaining stable gas outlet temperatures and ensuring compliance with environmental and operational standards.
