Methanol plant

Motunui is the location of the Motunui methanol plant, the largest in the world at the time of construction.[1] It was opened in 1986 to convert natural gas to methanol and the methanol to synthetic petrol using a process developed by Mobil. The plant was one of the Think Big projects of the Third National Government. The process became uneconomic in the late 1990s as a result of falling oil prices, so the synthetic petrol part of the plant was decommissioned, with the production of synthetic petrol ceasing in April 1999.[2] The plant instead produced methanol for export. Production of methanol ceased in 2004 as the approaching depletion of the Maui gas field raised gas prices.[3]

In 2005, an unmanned production station for the new offshore Pohokura oil/gas field was constructed immediately west of the Motunui plant. This began commercial production in September 2006.[4] In 2008, methanol train No.2 was recommissioned followed by train No.1 in 2012.[5]

Currently owned and operated by Methanex, the plant's two trains have a total annual production capacity of 2.4 million tonnes of methanol.[5]
