BOC Gases Specialty Gases Plant

BOC Gases – Project Excalibur

Gas Blending, Processing & Abatement Systems

Triplenine Group delivered a complex gas handling and processing solution for BOC Gases’ Project Excalibur, involving the installation of integrated gas blending, cylinder preparation, disposal and abatement systems.

The project required the coordination of multiple gas types, hazardous classifications and high-integrity piping systems within a live industrial environment.

Project Highlights

• 450+ Individual Process Lines Installed

• 4,000 Metres of Tube & Pipework (¼” to 1½”)

• 100% Orbital Welded Joints, including high-pressure oxygen lines using wire feed orbital welding

• 28 Tradesmen On Site

• 6-Month Delivery Program

Scope of Works

Gas Blending Systems

Installation of multiple gas blending booths designed to handle oxidiser, flammable, corrosive and hydrocarbon gases. These systems incorporated multi-line manifolds, precision control and integration with downstream processes.

Cylinder Preparation Systems

Delivery of dedicated cylinder preparation stations for various gas types, including purge, evacuation and preparation panels to ensure safe handling and contamination control.

Gas Disposal Systems

Construction of controlled gas disposal booths to safely vent and manage flammable, toxic and corrosive gases, fully integrated with the site’s abatement systems.

Abatement & Scrubbing Systems

Integration of chemical scrubbing systems using caustic and acid solutions (NaOH / H₂SO₄) to neutralise hazardous gas streams prior to discharge.

Vacuum & Evacuation Systems

Installation of vacuum pump systems across preparation and blending areas to enable effective purging, evacuation and safe system operation.

Raw Material Storage & Distribution

Development of gas storage manifolds and distribution networks supporting oxidiser, flammable and high-purity gas supply across the facility.

Gas Analysis Systems

Integration of on-line analysers for cylinder preparation and high-purity gas verification, ensuring product quality and compliance.

Outcome

Project Excalibur delivered a fully integrated gas processing system that improved safety, enabled precise gas blending and ensured compliant handling and disposal of hazardous gases.

The use of full orbital welding across all systems provided a high level of consistency, cleanliness and integrity—critical for high-pressure oxygen and specialty gas applications.
