Condensate stabilisation simplified block flow diagram encompassing all three options (multistage flash only, distillation column only, combined flash + distillation column 

A generic technology description is provide, encompassing three possible designs:

• Multi-stage flash only: in the multi-stage flash variant, all four stages are used and no distillation column follows. A direct-fired or hot oil feed heater upstream of the final flash vessel raises condensate temperature to 120–160°C to ensure adequate stripping to meet the RVP specification.
• Distillation column only: in the pure distillation variant, the flash stage is omitted entirely and raw condensate from the slug catcher proceeds directly to feed preheating and the stabiliser column.
• Combined flash + distillation column: in the combined variant, only the 1st Flash (HP) stage is used to remove bulk C₁–C₂, after which the pre-flashed condensate proceeds to the stabiliser column. This reduces column diameter and reboiler duty by 20–35% compared to the pure distillation variant.
