The Northern Gas Pipeline Project involves the construction of a 622 km, 12 in. gas transmission pipeline between Tennant Creek in the Northern Territory and Mount Isa in Queensland.

In order to meet the East Coast Market sales gas specifications, the start of line compressor station will be designed with the ability to treat gas from various Northern Territory sources. For this project, SUEZ will be responsible for the design and manufacture of a complete gas treatment system including cryogenic nitrogen removal technologies for the Phillip Creek compressor station.

The SUEZ gas treatment system incorporates innovative nitrogen removal technology not currently installed in the Australian domestic natural gas market in addition to filtration, sweetening (CO2 removal) via an amine system, dehydration using a molecular sieve and a guard-bed for the nitrogen removal unit.
