The Ca Mau Gas Processing Plant can produce 600 metric tonnes of liquefied petroleum gas and 35 tonnes of condensate a day, the company said in a statement late on Wednesday.
The facility will process natural gas from offshore southern Vietnam and the joint development area between Vietnam and Malaysia, PetroVietnam Gas said.
The government said in a separate statement the plant will meet around 10 percent of Vietnam's demand for LPG.
