Startup demonstration of a FALCO electric catalytic oxidizer for industrial vapor treatment. FALCO catalytic oxidizers are frequently used to destroy hydrocarbon vapors from process exhaust streams.
System is started on dilution air and catalyst is heated to reactive temperature. Once at temperature, vapor introduction is enabled, allowing vapors to pass through the catalyst where they are destroyed. A heat exchanger recovers discharge heat to preheat inlet flow. Process vapors often provide sufficient recovered combustion heat so electric heat is minimal. Temperature controllers regulate inlet concentration by adjusting dilution blower speed. Speed is increased during high mass flow of hydrocarbon vapors, and decreased to save energy during low mass flow or standby.
