Gas condensate stabilization unit

Gas condensate stabilization unit

The main purpose of condensate stabilization units (CSU) is to provide the required values of saturated vapor pressure by distillation of light fractions.

Stabilization of gas condensate by degassing or separation is based on a decrease in the solubility of low-boiling hydrocarbons in condensates with an increase in temperature and a decrease in pressure. When using stabilization units, the condensate yield is greater, and the amount of waste gases is less than when using staged degassing.

Three methods are used to stabilize gas condensate:

  1. Stepwise weathering (separation, degassing)
  2. Rectification in stabilization columns
  3. Combination of separation and rectification

To stabilize the condensate, 1-, 2- and 3-stage degassing schemes can be used.
