FERTILIZER APPLICATIONS

Ammonia plants can increase profits by upgrading their centrifugal compressor labyrinth seals. A simple change from stationary aluminum labyrinth seals to composite labyrinth seals will increase compressor efficiency and throughput. Many ammonia plants have already made this upgrade in their syngas, air, and ammonia compressor trains with excellent results.

Boulden also designs, manufactures, and repairs custom-engineered bearings. For machines where tilt-pad bearings are running hot or experiencing wear, we can supply drop-in replacement bearings to reduce operating temperature, increase load capacity, and reduce wear. We can design and manufacture custom oil housing seals to eliminate oil leaks. We can also help you assemble custom spare parts kit boxes for your critical machines to make turnaround planning easier.

With our material solutions, you can upgrade pumps in critical services like Benfield Solution and boiler feed water. Our materials can withstand ammonia, nitric acid, amines, and can be considered for nearly any kind of product lubricated or non-lubricated bearing or bushing in your plant.
