Innovative US Static Mixing Device Chosen Over International Competitors for New Gas Terminal in Germany

Westfall's high shear, low headloss Static Mixer was chosen for German natural gas pipeline because of its proven durability and extensive proof of performance.

Westfall Manufacturing of Bristol, RI is a small company in a small state whose patented Static Mixers are chosen for big international jobs.

Their most recent award comes from German engineers who have connected two North Sea natural gas pipelines for a new Gassco terminal in Emden, Germany.

Westfall’s Low Headloss Static Mixer, Model 3050, was selected to blend the gases of varying densities, compositions, temperatures and flow rates after they entered the single pipeline to the Gassco storage tanks.

Gassco is the Norwegian state owned company that operates the pipelines and transportation of natural gas from the Norwegian continental shelf to continental Europe and Great Britain. 

Since the gas has to travel 600km in underwater pipelines, minimizing headloss is critically important. Project engineers in the US and Germany did extensive CFD and FEA analyses on Westfall’s Low Headloss model 3050 and other mixers before awarding the job to Westfall.

The Westfall mixer was selected because of its mixing and headloss efficiency, ease of installation, and because the CFD and FEA analyses projected a service life for the device of more than 30 years.  

The Low Headloss 3050 mixer can be made with a choice of 3 stages of mixing vanes welded at precise locations inside a pipe. The more vane stages, the better the mixing but the greater the headloss. German engineers evaluated all 3 versions and chose the 2-stage model, which yielded a CoV of .026 and a K-value of 1.13.

According to Bob Glanville, Westfall CEO, the mixer has been installed and the new Gassco terminal in Emden, Germany is undergoing final testing before starting full operation scheduled for July 2016.
