Air Liquide 4.0 Expansion

Project Summary

In 2008, Air Liquide expanded its global relationship with REC Group, the world’s number one producer of silicon materials for the solar photovoltaic industry, at their Moses Lake, Washington facility to supply carrier gases to a new polysilicon manufacturing plant.  Since 2005, IMCO has maintained a presence at REC Moses Lake and has performed various infrastructure phases of construction for the new manufacturing plant.  This proved to give IMCO a cutting edge in helping Air Liquide build their process facilities and integrate them into the existing refineries all while keeping the plant active.
