Tunnel gap gas cooler

Tunnel gap gas cooler

Tunnel cracked gas coolers ensure the rapid cooling of cracked gas in ethylene plants.

They each consist of a cooler with a steam drum and the associated riser and downpipe and can be integrated vertically or horizontally into the respective systems.

We supply our tunnel coolers for any desired throughput and heat output.

advantages

  • Large volume of water, a stable jacket around all pipes
  • Thin, stiffened tube sheet at the gas inlet - low material temperatures, low stresses
  • Special tube/tubesheet weld - no sharp edges, full penetration
  • High directional water velocity over the inlet tubesheet - no deposits
  • Any high operating pressure on the water side
  • Just one or two downcomers and risers per cooler
  • 0.5 Mo material - no post-weld heat treatment required
  • Even gas distribution to the bundled tubes thanks to the special inlet hood shape
  • Erosion protection shield optional - protection of the entrance floor from erosion
  • Targeted draining of the cooler during operation possible
  • Easiest maintenance
