Fertiliser and Ammonia

Advanced valve solutions for ammonia production

A robust, shiny metal ammonia storage tank with pipes and equipment is used in the petrochemical refinery for high-pressure iron storage.

Tackling industry challenges

Ammonia serves as a vital component in fertilisers and finds diverse applications across industries. Most ammonia plants are integrated within fertiliser plants. Ammonia acts as a refrigeration coolant, cleaning chemical, and intermediate in petrochemical production. At IMI Critical Engineering we specialise in providing precision-engineered valves crucial for ammonia production.


Specialized safety valves safeguard the ammonia plant by preventing overpressure incidents, ensuring a secure and reliable production process

Empowering process efficiency

Our valves enable regulator level control, compressor recycle, ammonia let down, steam conditioning, and venting. They offer precise control amidst high pressure, high pressure delta, high fluid velocity, extreme temperatures, and corrosive materials. Nitrogen-based fertilisers, the largest category, rely on ammonia.

Nitrogen and hydrogen react under high temperature and pressure to form ammonia, which is then used to produce nitrate fertilisers or mixed with carbon dioxide to create urea. Hence, ammonia plants are typically built alongside fertiliser plants. We address industry challenges by delivering high-quality valves that ensure efficient and reliable ammonia production in demanding conditions.
