Distillation Column Cooling

Process enhancement solutions delivering yields that impress

Aggreko Process Services helps refineries increase production rates and profitability by debottlenecking overheads condensers during the hot summer months. We’ve been able to restore columns overheads cooling capacities to winterlike conditions by installing temporary cooling solutions.


Some of the issues we’ve been able to address are:

  • Throughput loss
  • Product cut point giveaway
  • Excessive loss of propane to fuel gas
  • Insufficient sulfur removal from fuel gas in amine treating units
  • Inadequate column overhead pressure control
  • Increases in main fractionator column pressure that increase back-pressure to feed preheat furnaces or reactors
  • Overloaded wet gas compressors
  • Downstream gas plant column flooding

Our solutions can be designed and installed safely in weeks, without intrusive hot-taps, interruption in column operation, or need for an outage.
