Our Plant

Our production facilities

The LPG extraction plant and LNG production plant are located in the Kwinana Industrial Area, south of Perth.

The Air Liquide (WA) Pty Ltd air separation plant is located on the northern end of the site on land sub-leased from Kleenheat Gas.  The Fremantle Ports Kwinana Terminal and the HIsmelt plant are located northwest of the site.

Ready access is available to the Fremantle Ports Kwinana Bulk Berth-2 for LPG ship loading. Vehicle access to the site is available from Donaldson Road.

The LNG Plant design is based on well proven concepts and equipment, using Linde’s process technology with a closed single mixed refrigerant cycle selected as a liquefaction process.

The LNG plant is designed for the production of 175 tonnes per day – equivalent to a natural gas feed of approximately 10,200 kg/h.

The plant includes a 4000 m3 LNG storage tank and LNG truck loading facility.

The facility also features a:

  • pre-treatment section (CO2 removal and dehydration), a
  • liquefaction section (cold box, refrigeration and storage) and
  • loading facilities.

The feed gas to the LNG plant is taken from the lean residue gas stream from the LPG extraction plant.

Our process

The LNG plant’s process consists of the following key components:

  • CO2 Wash Unit: Amine wash column to remove CO2 from the feed gas to the LNG plant. The CO2 is removed to prevent any freezing. An amine stripper column removes the CO2 from the amine to allow the Amine (MDEA) to be recycled to the Amine wash column.
  • Dehydration: Drier columns remove moisture from the feed gas after the CO2 Amine wash column.
  • Cold Box: Liquefaction heat exchangers contained in an insulated cold box to liquefy the treated inlet gas feed to LNG. The natural gas is liquefied by using a number of mixed refrigerant streams at different temperatures, pressures and compositions.
  • Refrigeration System: A two stage compressor system driven by a gas turbine is used to compress the mixed refrigerant streams required for liquefaction. The mixed refrigerant streams are made up of methane, ethane, butane and nitrogen.
  • LNG Storage:  The LNG product is stored in a 4,000 m3 sphere. The LNG sphere is surrounded by a bund designed to contain the full contents of the storage tank.
  • LNG Loading System: The LNG product is loaded to road tankers for transportation and sale.
