Petrochemical producer PT Trans-Pacific Petrochemical Indotama (TPPI) has begun work to expand its sole refinery in Tuban, East Java, in cutting Indonesia’s petrochemical imports. TPPI, a subsidiary of state-owned oil and gas giant Pertamina, plans to raise its output capacity by 30 percent to 780,000 t/y. The refinery can produce either gasoline or paraxylene. The producer expects to finish designing the facility by September 2020 and finish building five storage tanks, which are key infrastructure, by December 2021. The expansion project will cost USD 180 million.
