Process Engineering

Recognized Process Expertise

GLE was built on a solid foundation of excellence in process engineering, a tradition which we proudly continue today. Our impressive group of process engineers is unrivalled, and capable of handling nearly all oil and gas processes, and many industrial processes. In addition to our broad experience, we have slowly developed into the top acid gas injection firm in the world, with several dozen completed acid gas injection projects.

Over the years, we have built a multitude of facilities, published many technical papers, and developed proprietary processes. Since 1987, GLE’s process team has completed such typical tasks as:

• Conceptual Design, Pre-FEED and FEED Studies
• Process Flow Diagrams (PFDs)
• Piping and Instrumentation Diagrams (P&IDs)
• Process and Flare Studies
• Equipment and Vessel Sizing, Design and Selection
• HAZID, HAZOP, LOPA and other Safety Studies
• Facility Troubleshooting and De-Bottlenecking
• Operator Training
• Start-up and Commissioning Support
• Process Confirmation and Due Diligence Checks
