PT Pupuk Kalimantan Timur (Pupuk Kaltim) says that it has begun work on a revamp to its number 2 ammonia plant. The plant, which was originally constructed in 1984, has a capacity of around 1,500 t/d of ammonia. The revamp, which is being carried out internally by Pupuk Kaltim, aims to improve energy efficiency at the ageing plant and reduce carbon emissions, according to the company. The revamp is expected to extend the plant’s operational life, improve production reliability, and support Indonesia’s long-term fertilizer supply amid rising domestic demand.
