Condensate Stabilizer

Compass Model No.: Process Equipment – Refluxed Stabilizer

Application: Liquid product vapour pressure and composition control

Customer Objective:

  • Control top and bottom product vapour pressure and key component content to allow tank and bullet storage.
  • Offload existing de-ethanizer to allow more plant throughput.
  • Sweeten inlet liquid.

Design Challenges: Generate discrete product specifications at both tower top and bottom while condensing using air cooler. Eliminate hydrate formation on inlet level control.

Compass Solution: Reboiler and reflux system, cooling air temperature controlled condenser, inlet heater and feed/bottoms exchanger.

Inlet Flowrate Capacity: 2500 bbl/d (397 m3/d)

Product Flowrates: 

  • 257 bbl/d (41 m3/d) Propane/butane mix
  • 796 bbl/d (127 m3/d) Pentanes plus
