Thermal oxidizer performs well in preliminary tests

By | July 08, 2008
California-based Pro-Environmental Inc. said preliminary tests conducted by a third party showed excellent performance by a regenerative thermal oxidizer (RTO) that the company designed and built for Otter Tail Ag Enterprises LLC, a 55 MMgy ethanol plant in Fergus Falls, Minn. Pro-Environmental reported the three-canister RTO downstream of the rotary dryer showed nitrogen oxide emissions that amounted to 20 percent of permit levels, and volatile organic compound emissions at almost zero. The air-pollution-control installation still has to undergo formal testing by the Minnesota Pollution Control Agency. Otter Tail Ag Enterprises began production in March.
