The Challenge

Greenfield cryogenic gas processing facilities represent some of the most technically demanding construction projects in the midstream sector. The project required building an integrated facility from the ground up, coordinating multiple high-capacity process trains, heavy rotating equipment, and critical electrical systems — all while maintaining an uncompromising safety standard across the field crew, engineering teams, and vendor partners.

Scope of Work

The project encompassed the following key components across five major system categories:

Gas Processing

200 MMSCFD UOP Cryogenic Gas Processing Train
600 GPM Amine Gas Treating
40 GPM TEG Dehydration

Inlet & Separation

5,000 BBL, 260 MMSCFD (6) Finger-Type Slug Catcher
5,000 BPD Two-Tower Condensate Stabilizer with Overhead Compression

Compression & Electrical

(3) 1,600 HP Refrigeration Compressors
(3) 6,000 HP Electric Drive Residue Compressors
New Substation: site prep, equipment installation, power & control wiring, structural steel erection, 360’ ground wells, 4” aluminum bus welding
PDC and MCC Building Handling & Installation

Utilities

Flare System
Liquid Outlet Supply
Fuel Gas System
Instrument Air System

Storage & Environmental

Raw Water, RO Water, TEG, Amine, Condensate, and Slop Storage
Thermal Oxidizer

Spotlight: Substation Construction

One of the most technically complex elements of this project was the construction of a brand-new substation, built from the ground up. Scope included comprehensive site preparation, full equipment installation, power and control wiring, structural steel erection, installation of 360-foot ground wells, and the welding of 4-inch aluminum bus. This electrical backbone was essential to energizing the facility’s large-horsepower electric drive compressors and overall plant operations.

Execution & Safety

Safety and execution quality were the dual pillars of this project from the first day of site preparation through final mechanical completion. Field crews operated under a rigorous safety management framework, coordinating across multiple active work fronts simultaneously. Engineering teams provided continuous technical support to maintain schedule momentum without compromising quality or compliance. Vendor partners were held to the same standards, ensuring that every component was installed to specification.

The result: zero lost-time incidents and delivery on schedule — a benchmark outcome for a project of this complexity.

Results & Outcomes

Schedule	Full mechanical and civil construction completed on schedule.
Safety	Project executed with an uncompromising safety culture across all field crews and vendors.
Capacity	200 MMSCFD UOP cryogenic train operational; 260 MMSCFD slug catcher in service.
Infrastructure	New substation commissioned from the ground up, powering (3) 6,000 HP electric drive compressors.
Reliability	Integrated utilities, storage, and environmental systems provide long-term operational reliability.
Collaboration	Seamless coordination between field crews, engineering teams, and multiple vendor partners.

Conclusion

The completion of this greenfield cryogenic gas processing facility is a defining project for NTACT Operations. It reflects the team’s ability to manage complex, multi-system construction projects with precision, safety, and accountability. From the initial site prep through to final mechanical completion, every phase was driven by a commitment to long-

term reliability for the client.

This project represents a strong collaboration between field crews, engineering teams, and vendors — focused on execution, safety, and delivering an asset built to last.
