Ammonia is used as a raw material in the chemical industry. The ammonia produced by Pupuk Kaltim is marketed in liquid form at -33°C with a minimum purity of 99.5% and a mixture (impurity) with up to 0.5% water content.

Ammonia is formed from natural gas as raw material which is reacted with air and water vapor and gradually processed at high temperature and pressure through several catalyst-containing reactors. Pupuk Kaltim has five Ammonia plants, namely Plant 1A, Plant 2, Plant 3, Plant 4, and Plant 5. The total capacity reaches 2.74 million tons of Ammonia per year.

The main raw materials for ammonia product formation in the last 3 years are shown in the following table:

In 2024, the use of air as raw material amounted to 3,101,595,452 Nm3 or 39% of the total raw material requirement for producing ammonia. In the urea fertilizer production process, all raw materials (liquid ammonia and CO₂) are fully consumed, therefore cannot be recycled.
