Case Study: N2 Solutions’ Successful Nitrogen Purging at LNG Facility

This case study highlights N2 Solutions' expertise in managing complex nitrogen purging operations within a high-stakes LNG facility, showcasing our ability to deliver reliable results on time and within scope.

Location

Cameron, Louisiana

Pipeline Specifications

Line Size: TBD

Volume: 83 mmscf

Pressure: TBD

Background

LNG facility in the Southwestern coast of the Gulf of Mexico required nitrogen services for purging and preparing various headers and beds within their facility. The scope of work involved purging operations across multiple locations within the facility, each with specific flow rates and temperature requirements. The goal was to ensure the facility's readiness and safety before operational activities commenced.

Scope of Work

The scope of work was extensive and included nitrogen purging of the Mole Sieve, Defrost Header, and Mercury Bed pipelines. Each location required careful planning and execution to meet specific flow rate and temperature requirements over a defined duration. The project was designed to operate continuously over a 28-day period, ensuring that all sections were purged effectively within the scheduled time frame.

The project included purging activities at three critical locations within the facility:

1. Mole Sieve - Purging between 15,000 scfh to 450,000 scfh at approximately 125˚F, with an estimated total consumption of 15 mmscf.

2. Defrost Header - Purging between 15,000 scfh to 600,000 scfh at approximately 125˚F, with an estimated total consumption of 26 mmscf.

3. Mercury Bed - Purging between 15,000 scfh to 450,000 scfh at approximately 125˚F, with an estimated total consumption of 10 mmscf.

The Execution Plan

N2 Solutions developed a detailed execution plan to ensure the project’s success. The plan included maintaining 24/7 operations to meet the demanding schedule, with sufficient resources allocated to cover the extensive purging requirements. Strict safety protocols were implemented, particularly in managing the handling of nitrogen and high-pressure systems. Regular communication with the LNG facility team was also a key component of the plan, ensuring that all operations were aligned with the facility’s requirements.

Achievements

• Successfully purged the Mole Sieve and Defrost Header systems, achieving the required flow rates and temperatures.

• Completed the operations within the projected 28-day timeline without any safety incidents or equipment failures.

• Provided comprehensive documentation and post-operation reports to the LNG facility, ensuring all requirements were met and that the systems were ready for the next phase of operations.
