Flow control solutions for petrochemical

At IMI Critical Engineering, we provide bespoke, custom-engineered valves for petrochemical applications like delayed coking, PDH, FCC, ethylene, fertiliser, and ammonia production. Our specialised designs optimise plant performance and safety, leveraging decades of expertise across various refining and chemical processes.

The IMI Critical engineer inspects power plant flow control systems for performance and safety, and recommends the best solutions for optimal efficiency.

Custom-engineered valves for petrochemical applications

We offer custom-engineered valves for critical applications in the petrochemical sector. Leveraging our decades of experience in the refining, chemical, fertiliser, ethylene, and ammonia industries, we have developed world-leading valve technologies designed to optimise plant performance and safety.

Our valve solutions excel in delayed coking, Catofin® (propane dehydrogenation), ethylene, and fluid catalytic cracking (FCC), meeting the specifications of process licensors such as UOP, Lummus, CB&I, and Exxon.

 

Drawing upon extensive expertise spanning decades, we have developed world-leading valve technologies meticulously designed to enhance plant performance and safety.

Chemicals

Chemical production relies on chemistry and engineering to create products like vitamins, oxygen, cosmetics, and raw materials. To maintain purity, clean production lines are essential. IMI Critical valves endure high pressure, temperature, and corrosion in chemical production, while being made in contamination-free clean rooms, especially crucial for oxygen production.

Fertiliser & ammonia

Ammonia is crucial for fertilisers and various industries. IMI Critical supplies valves for ammonia production, ensuring precise control under extreme conditions. Nitrogen-based fertilisers are vital for plants, and ammonia is produced by combining nitrogen from air with hydrogen. It is used to make nitrate fertilisers or mixed with carbon dioxide to create urea. Therefore, ammonia plants are commonly integrated into fertiliser production facilities.

Ethylene

Ethylene is a crucial building block for everyday goods. IMI Critical is the leading supplier of severe service valves for ethylene production, including furnace isolation valves and a state-of-the-art double disc through conduit (DDTC) gate valve design. We also provide control, bypass, anti-surge, steam control, and isolation valves, with a substantial global presence in ethylene plants.
