De-noxification systems are used to reduce the nitrous oxide emissions from the discharge of electrical power generators. The units consist of high volume, low pressure blowers and a pressure controlled liquid ammonia stream. The stream is injected into the waste gas upstream of a catalyst to obtain government regulated discharge levels. Fil Sep has fabricated skids for power generation facilities throughout the India. All of the skid’s low pressure blowers were run in our factory to verify vibration and power consumption. Fil Sep has also provided high temperature insulation for process gas piping, blowers, and valving.
