Case Study 1: NGL Recovery Debottlenecking

Challenge Faced

Value Delivered 

  • Operating issues in amine, mole sieve dehydration, condensate stabilizer, and demethanizer units

  • Client wanted to increase plant capacity above nameplate capacity

  • Increased plant capacity from 250 to 400 MMscfd (60% increase to the existing nameplate capacity) with $0.80/scf

  • Debottlenecked operating issues of existing process units

Case Study 2: Operation Excellence for NGL Fractionation

Challenge Faced

Value Delivered 

  • High NGL feed quality variation

  • Client wanted:

    • to increase further throughput

    • to save energy

    • to handle various feedstock impurities

    • to reduce production cost

  • Increased NGL fractionation throughput and efficiency

  • Minimized equipment downtime

  • Minimized operating cost (Processing fee)

Case Study 3: Operational Improvement for a NGL Recovery Plant

Challenge Faced

Value Delivered 

  • Client wanted to increase the NGL facility performance (more profit)

  • Client wanted to save energy

  • Client wanted to further throughput

  • Operating issues at pretreatment units (AGRU and mole sieve dehydration)

  • Increased NGL plant throughput and efficiency

  • Identified and debottlenecked pretreatment operating issues, feeding on-spec stream to liquidation

  • Resolved the CO2 freezing through cold boxes

  • Reduced the refrigeration system load

Case Study 4: Change of Operation Mode for a NGL Recovery Plant

Challenge Faced

Value Delivered 

  • Client wanted to increase the gas plant performance (more profit)

  • Client wanted to save energy:

    • ​No ethane demand

    • Deep ethane recovery system

  • Changed the mode of operation successfully with on-spec residue gas and NGL

  • Resolved the CO2 freezing in top of the demethanizer

  • Reduced the refrigeration system load
