Petronas Methanol (Labuan) Sdn. Bhd. (PMLSB) is a subsidiary of Petronas. It was formed in 1992 when Petronas bought the methanol plant from Sabah Gas Industries. The plant was commissioned under Sabah Gas Industries in 1984 to produce Grade AA methanol using Lurgi's low-pressure combined technology. The plant is located in the Malaysian island of Labuan.
The main production units are:
- Unit 100: Steam reforming
- Unit 200: Methanol synthesis
- Unit 300: Distillation
In 2005, works began on a new methanol plant. Using Lurgi's MegaMethanol technology, the plant has a nameplate capacity of 5000 mtpd, more than double that of the existing plant.
