Enogex Cox City Fire Rebuild

Enogex Cox City Fire Rebuild

Location: Cox City, Okla.

Client: Enogex

Completion Date: 2011

Burns & McDonnell was contracted by Enogex to provide demolition, engineering, procurement and construction services to rebuild the Cox City Gas Processing plant. Burns & McDonnell provided services to demolish the existing facility and retrofit an existing idle gas processing plant into the location. The goal was to complete the project on an aggressive schedule, and return the unit to service within nine months. The plant processes 125 MMSCFD of wellhead natural gas, utilizing a turbo expander refrigeration process. The facility also utilizes amine to purify the NGL product stream by reducing the CO2 content.

The Enogex gas plant in Cox City, Okla., experienced an explosion and fire which caused extensive damage to the gas processing unit and the electrical infrastructure of the entire facility. Because the unit was not shut down properly and had multiple unknowns due to the explosion, the initial investigation and demolition required the utmost vigilance in safety.

With business at a stand-still, Enogex was pressed for time and losing money. An aggressive schedule demanded that we do it right, we alleviate mistakes and we move fast.

Our engineering team quickly came up to speed to understand and integrate the new unit into the existing facility. The construction team employed daily progress meetings in order to measure and adjust the schedule on the fly.

The project utilized an existing cryogenic plant fabricated by TH Russell to replace the damaged facility. The scope included the investigation of peripheral equipment, systems and instruments for potential reuse within the new facility. The project required the integration of the new skids onto the existing plant site and an evaluation of the unit for operability and performance. The additions of a new amine unit, pipeline pumps, flare and instrument system, and power and control wiring throughout the facility were also evaluated and included.

Burns & McDonnell's engineers, designers and CMs were on-site to assist with commissioning and startup. Twenty-four hours after construction completion, the plant was running at full capacity.
