A method of providing a mixture of lean and rich gas of a desired composition by means of a jet compressor system comprising two or more jet compressors comprising: (1) adjusting the jet compressor system being used to mix the lean and rich gas to provide a leaner gas mixture than the desired composition; (2) then adding a predetermined amount of rich gas to the leaner gas mixture to attempt to obtain the desired composition; and (3) varying the amount of rich gas added to the leaner gas in response to the measurement of gas properties in the jet compressor system to thereby more nearly obtain a gas of the desired composition. Preferably the lean gas comprises air, blast furnace gas, or BOF gas, and the rich gas comprises methane, natural gas, propane, or butane.
Method of providing a mixture of lean gas and rich gas of a desired composition by means of a jet compressor system comprising two or more jet compressors, and wherein each such jet compressor operates by passing said rich gas at high pressure through a nozzle into the throat of a venturi section to thereby produce suction which draws said lean gas at a lower pressure into said venturi section to thereby dilute said rich gas to a predetermined composition, comprising:
