Energy-saving gas condensate stabilization technology

Process Description
Feedstock – pressure reduced unstable condensate is fed into film-type column 1 above heat and mass transfer elements unit 2. Flash gas is removed from column overhead, and condensate is removed from bottom, which is supplied through heater 3 as refrigerant to heat and mass transfer elements unit 2. The cooled commercial condensate is discharged from the unit.

Process features

• An increase in condensate gas output by 5-7% compared to technology of stepwise degassing
• Reduction of stabilization gas consumption
• Elimination of low-pressure gas formation
• Reduction of capital investments and operating costs

Technical Specification

• No performance limitations
• Temperature of unstable gas condensate: from minus 30 °C to minus 60 °C
• Pressure 2.0–5.5 MPa
• Stable gas condensate output is up to 99.9% of the potential
