Application:
Liquid product vapour pressure and composition control
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
