NATURAL GAS GATHERING

Designing for Future Plug-and-Play

LOCATION: USA
MARKET: Natural Gas Gathering

THE CHALLENGE

Additional gas production in the basin required our client to build a new compressor station, doubling the client’s compression capacity in the area from 120 MMscfd to 240 MMscfd. Due to the increasing CO₂ content of the gas in the basin, the new station needed to include future Amine gas treatment in addition to gas dehydration. Functionality for gas blending from other high-pressure inlet sources with the sales gas was required to meet CO₂ content and sales gas specifications in the short term. The client also wanted functionality to be able to combine low-pressure and high-pressure liquid products through a single sales pipeline.

Developing a Plan to Meet Client Expectations:

• Leveraged the client’s previous compressor station design from CANUSA EPC
• Identified operational improvements for the new station

Sourced New Equipment:

• Low Pressure Inlet Slug Catcher
• Heater Treater
• High Pressure 3 Phase Separator
• Pipeline Pumps
• Motor Control Center Building

Execute Value Engineering to Support the Project Schedule:

• Redesigned layout for Glycol Heater Package
• Sized VRU package for expansion
• Specified switchgear and MCC equipment to remove from the critical path
• Reduced the height of the slug catcher package to lower site construction costs

THE RESULTS:

Provided Construction Package with Designs for Future Expansion

• Future site compressor additions require no additional mechanical design
• Design allows for additional inlets and Amine unit

Operations Improvements

• Consolidated low-pressure inlets to allow for a single slug catcher vessel
• Addressed issues with high-pressure drains
• Improved isolation, access, and piping for compressor packages
