TGAST Case Study

CompAir supplies the compressed air system at the Terengganu Gas Terminal (TGAST) in Malaysia

Gardner Denver won the EPC contract for supplying the compressed air system for Petronas’ Terengganu Gas Terminal (TGAST) in 2014 from Samsung Engineering Co. LTD, who had been awarded the multi-disciplined project management. Samsung entrusted Gardner Denver with the supply of air compressors, air dryer and nitrogen generation packages. TGAST is a state-of-the-art facility, which has the capacity to process up to 700 million standard cubic feet per day (mmscfd) of gas from the North Malay Basin, offshore Terengganu.

Compressed Air Station description

Our team carried out the plant design as a first step. The scope of supply included the design, fabrication, inspection, transportion, testing and commissioning of the compressed air equipment and plant systems including all accessories and elements necessary for its operation. The compressed air station consists of 3 oil-free screw compressors, 2 air dryer and 2 nitrogen generation packages, filters and accessories. The equipment was installed in a common skid including air dryer and nitrogen generation packages, except for the air receivers. In addition, we provided a master control panel, which manages the entire compressed air system equipment.

Unique design

The unique design of the oil-free compressors included the two-stage oil-free screw compressor range which was designed with a focus on operational safety in demanding applications. The innovative clear construction delivered state-of-the-art performance, in-depth control and outstanding reliability. CompAir's own designed and manufactured airends work at constant low temperature levels and reduce the compressor’s lifecycle costs.

Nitrogen generators - the perfect solution

The nitrogen generation plant utilises a Pressure Swing Adsorption (PSA) system, consisting of two adsorption towers filled with a carbon molecular sieve. Compressed and purified air is passed through the towers with oxygen being adsorbed to leave a nitrogen enriched gas – oxygen concentration can be reduced to the client’s own purity level requirements.

Compared to outsourced supplies, on-site nitrogen generation offers greater flexibility and has a significant impact on time and costs.

• Enhanced safety without the need to store or handle high pressure cylinders • Reduced downtime due to an on-demand supply • Cost savings following payback of up to 90% • High purity nitrogen at consistent flow and pressure
• Compact space saving design
• Flexible modular design
• Low cost of ownership
• Proven high reliability
   

The benefits of the air dryer package

• Robust and reliable, industry proven design
• Suitable for all industries and applications. Some adsorption dryer regeneration methods prevent their use in certain industries/applications
• Lower capital investment and reduced complexity compared to other adsorption dryer regeneration methods
• Lower maintenance costs in comparison to other adsorption dryer regeneration methods – no heat, heaters or heat related issues
