A flashback protection apparatus and method for suppressing deflagration of a deflagration-susceptible gas in a flow system in which the deflagration-susceptible gas is flowed. The method of the invention comprises monitoring the combustible gas to detect deflagration therein, and upon detection of a deflagration event producing a propagating flame front, opposedly directing at the propagating flame front a pressurized non-flammable gas in a sufficient volume and at a sufficient velocity to provide a non-flammable gas flow having a momentum at least opposedly equal to momentum of the propagating flame front and the associated accelerated combustible gas undergoing deflagration.

Flashback protection apparatus and method for suppressing deflagration

A device for oxidizing gaseous materials, comprising a combustion chamber, wherein the device and the combustion chamber both have a top and a bottom, the device further having a gas outlet and being adapted to operate in conjunction with means applying negative pressure to the outlet, means for introducing process gas and a source of fuel into the top of the combustion chamber, means for effecting heat exchange between oxygen-containing gas and the combustion chamber to preheat the oxygen-containing gas, means for introducing the preheated gas into the top of the combustion chamber, means for mixing the preheated gas with the process gas and fuel so that the mixture can burn in the combustion chamber to form an exhaust gas, means for permitting the gas to exit from the bottom of the combustion chamber, means for diluting the exhaust with air to form a flue gas, and means for directing the flue gas from the bottom of the combustion chamber out of the outlet of the device. The heat exchanger may concentrically surround the combustion chamber, and the preheated oxygen-carrying gas may swirl in a first direction as it enters the combustion chamber, there to be mixed with process gas and fuel swirling in the opposite direction. Means may be provided for removing particulate materials from the combustion chamber. Also disclosed is a method for incinerating materials in a gas stream using the disclosed incinerator.

Incinerator for complete oxidation of impurities in a gas stream

A system for containing and detoxifying a gaseous stream, comprising a storage housing containing one or more sources of toxic gas, means for applying negative pressure to the storage housing to continuously exhaust a gaseous stream therefrom, and a treatment housing interposed in the gaseous stream, the treatment housing containing one or more layers of solid sorbent material capable of removing the toxic gas from the stream, wherein a flow of treated gas that exits the treatment unit may be safely released to the environment.

Device for preventing accidental releases of hazardous gases

An apparatus and process for adsorbing volatile organic compounds, or VOCs, and efficiently regenerating adsorbent material in an emission control system. Flue gas, emitted from a combustion unit burning an outside fuel and desorbed VOCs, is humidified and cooled with a set of water injectors. The resultant humidified flue gas is directed through the adsorbent material, which is rapidly superheated without pressurization. A method for controlling the regeneration cycle of the emission control system includes at least three sensor configurations including a breakthrough sensor, a desorbed gas sensor and a flue gas temperature sensor.
