Gas and condensate will first arrive via the trunkline into the slugcatcher, where the two products will be separated.

Condensate will then be stabilised (volatile gases removed) before it is stored in large tanks ready for export via oil tankers to refineries in Australia and overseas.

Some gas will be sent to the domestic gas plant, which will process and compress up to 200 terajoules of domestic gas a day for Western Australian markets. This gas will be exported via a pipeline of about 90 kilometres in length to the main Dampier to Bunbury Natural Gas Pipeline.

The bulk of the gas will be sent to the two LNG processing trains where impurities and inert gases will be removed and the natural gas chilled to minus 130 degrees Celsius, at which point it flashes over to a liquid 600 times the density of the natural gas. It is further cooled to minus 161 degrees Celsius and sent to insulated storage tanks to await export overseas via LNG tankers.
