Abstract
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.
Claims21
A method for treating gas storage cabinet exhaust containing a mixture of air and hazardous gas, said method comprising the steps of:
- continuously applying negative pressure to a gas storage cabinet containing a source of hazardous gas to remove air and any leaking hazardous gas as gas cabinet exhaust from said cabinet;
- continuously directing the gas cabinet exhaust through a treatment unit having at least a first plenum and through at least one layer of sorbent material housed in the first plenum, thereby removing any hazardous gas from said gas stream.
A method for treating vented gas storage cabinet exhaust containing the accidental release of hazardous gas from compressed cylinders stored in a gas storage cabinet, said method comprising the steps of:
- enclosing at least one source of hazardous gas in the vented gas storage cabinet;
- continuously applying negative pressure to the vented gas storage cabinet so as to draw ambient air from outside said gas storage cabinet into said cabinet;
- mixing the ambient air with any hazardous gas which accidentally leaks from the cylinder so as to form a mixture of air and hazardous gas;
- directing the mixture away from the gas cabinet and towards a treatment unit;
- and
- directing a first portion of the mixture into a first plenum of the treatment unit and across a first layer of sorbent material capable of chemically interacting with the hazardous material so as to produce a first treated effluent.
