Liquid Air WA Pty Ltd proposes to establish an Air Separation Unit to produce liquid oxygen, nitrogen and argon, and gaseous oxygen and nitrogen at Lot 129 Leath Road, Naval Base, immediately north of Wesfarmers Ltd's LPG extraction plant, and adjacent to Mason Road.

The proposed plant would supply oxygen and nitrogen to the Cooljarloo Joint Venture (CJV) pigment plant, and the local merchant market.

The pigment plant will require up to 35,000 tonnes per annum (t/a) of oxygen and 30,000 t/a of nitrogen. Argon and additional liquid oxygen would be produced for the local domestic market. The Air Separation Unit has been designed with sufficient capacity and area to expand, so as to be capable of supplying additional major industry in the Kwinana area.
