Geneva Nitrogen

Orem, Utah

Year Completed: 2011

Scope: Geneva Nitrogen is a unique facility in that it uses ammonia refrigeration systems to chill ammonia. They can store millions of pounds of ammonia at any given time. In 2011, LA Roser provided a new shell-and-tube heat exchanger to chill a small part of their process. This particular chiller presented a challenge, in that the heat exchanger had to replace an existing one, and still remain on the skid package originally installed.

Louis A. Roser Company designed a refrigeration system to lower the pressure of rail car tankers reduce the offloading time. An all-stainless steel ammonia refrigeration system was integrated into their existing processes and reduced rail car unloading time by 50%.

Linde Gas

Ohio; Price, Utah; Grand Junction, Colorado

Year Completed: 2012/On-going

Scope: Linde Gas has utilized LA Roser for many aspects of their system, including service work and controls upgrades. In 2012, the facility in Lima, Ohio upgraded the compressor controls from a manual, analog system to a more current, user-friendly digital control system. This greatly enhanced the compressors, allowing them to all communicate together, and ensure the system is not over-working.

This greatly enhanced the compressor performance, allowing the controls and compressor to work together efficiently.

ATK/Thiokol

Magna, Utah

Year Completed: 2008/2009/2011

Scope: ATK is a major name in space and science, providing NASA with the solid-state rocket fuel for the space program. They use an ammonia refrigeration system to chill a brine solution, which is used in another part of their processing. In 2008 and 2009, LA Roser began upgrades to their system, including replacing the original upright compressors with the advanced screw compressors used now. In 2009 and 2011, ATK worked with LA Roser to upgrade the old, very large, shell-and-tube heat exchangers to the new, efficient plate-and-frame chillers. These only take up a small fraction of the space for the same capacity.
