A new liquefaction system that’s better for the environment and community.

It’s in the works at CNG’s Rocky Hill, Connecticut, liquefaction plant where we served as the owner’s engineer to upgrade the plant’s liquefaction system. The upgraded liquefaction system will have a 4,300Hp motor driven nitrogen recycle compressor to replace an aging natural gas turbine.

Building upon five years of providing engineering services — and no safety incidents — at Rocky Hill and its sister plant, Milford, the liquefaction upgrade is the latest project at CNG. We’ve assisted them through the bidding and selection process to bring the right engineer-procure-construct contractor on board. HDR’s technical oversight has helped to keep the project on track for completion in 2018. 

When the new system goes live, the local community will benefit from lower emissions and more efficient operations at the plant.
