Abstract
A system for treating flammable effluent gas is provided. The system includes an exhaust conduit to carry the flammable effluent gas to an abatement unit, a control system coupled to the abatement unit to determine an operating parameter of the abatement unit, a bypass valve coupled to the exhaust conduit which is an operative responsive to the monitoring system, and a source of second gas to be mixed with the effluent gas diverted from the abatement unit when the bypass valve is operating in a bypass mode to provide a mixed gas having a flammability lower than the effluent gas. Methods of the invention as well as numerous other aspects are provided.
