Abstract
Abstract A method of incinerating a stream of combustible vent gas wherein the vent gas is intimately mixed with a stream of combustion air and the resulting air-gas mixture is combusted so that the stream of vent gas is converted to inert products of combustion. The products of combustion are quenched and released to the atmosphere.

Claim 1
Independent Claim
201 words
A METHOD OF INCINERATING A STREAM OF NATURAL GAS COMPRISING THE STEPS OF: CONDUCTING SAID STREAM OF NATURAL GAS TO A COMBUSTION CHAMBER, CONDUCTING A STREAM OF COMBUSTION AIR TO SAID COMBUSTION CHAMBER, INTIMATELY MIXING SAID STREAM OF NATURAL GAS WITH SAID STREAM OF COMBUSTION AIR WITHIN SAID COMBUSTION CHAMBER, VARYING THE QUANTITY OF COMBUSTION AIR CONDUCTED TO SAID COMBUSTION CHAMBER IN DIRECT PREDETERMINED PROPORTION TO VARIATIONS IN THE QUANTITY OF NATURAL GAS CONDUCTED THERETO SO THAT WHEN SAID STREAM OF COMBUSTION AIR IS MIXED WITH SAID STREAM OF NATURAL GAS A SUBSTANTIALLY STOICHIOMETRIC MIXTURE RESULTS, COMBUSTING THE RESULTANT COMBUSTION AIR-NATURAL GAS MIXTURE WITHIN SAID COMBUSTION CHAMBER SO THAT THE MIXTURE IS CONVERTED TO A STREAM OF INERT PRODUCTS OF COMBUSTION, CONDUCTING THE STREAM OF INERT COMBUSTION PRODUCTS TO A MIXING CHAMBER, CONDUCTING A STREAM OF QUENCHING MEDIUM TO SAID MIXING CHAMBER, INTIMATELY MIXING SAID STREAM OF COMBUSTION PRODUCTS WITH SAID STREAM OF QUENCHING MEDIUM, VARYING THE QUANTITY OF QUENCHING MEDIUM CONDUCTED TO SAID MIXING CHAMBER IN DIRECT PROPORTION TO VARIATIONS IN THE TEMPERATURE OF SAID MIXTURE OF COMBUSTION PRODUCTS AND QUENCHING MEDIUM SO THAT SAID MIXTURE ATTAINS A DESIRED TEMPERATURE, AND RELEASING SAID COMBUSTION PRODUCTS-QUENCHING MEDIUM MIXTURE TO THE ATMOSPHERE.
Claim 2
Independent Claim

A METHOD OF INCINERATING A STREAM OF NATURAL GAS COMPRISING THE STEPS OF: CONDUCTING SAID STREAM OF NATURAL GAS TO A COMBUSTION CHAMBER, CONDUCTING A STREAM OF COMBUSTION AIR TO SAID COMBUSTION CHAMBER, INTIMATELY MIXING SAID STREAM OF NATURAL GAS WITH SAID STREAM OF COMBUSTION AIR WITHIN SAID COMBUSTION CHAMBER, VARYING THE QUANTITY OF COMBUSTION AIR CONDUCTED TO SAID COMBUSTION CHAMBER IN DIRECT PREDETERMINED PROPORTION TO VARIATIONS IN THE QUANTITY OF NATURAL GAS CONDUCTED THERETO SO THAT WHEN SAID STREAM OF COMBUSTION AIR IS MIXED WITH SAID STREAM OF NATURAL GAS A SUBSTANTIALLY STOICHIOMETRIC MIXTURE RESULTS, COMBUSTING THE RESULTANT COMBUSTION AIR-NATURAL GAS MIXTURE WITHIN SAID COMBUSTION CHAMBER SO THAT THE MIXTURE IS CONVERTED TO A STREAM OF INERT PRODUCTS OF COMBUSTION, CONDUCTING THE STREAM OF INERT COMBUSTION PRODUCTS TO A MIXING CHAMBER, CONDUCTING A STREAM OF QUENCHING MEDIUM TO SAID MIXING CHAMBER, INTIMATELY MIXING SAID STREAM OF COMBUSTION PRODUCTS WITH SAID STREAM OF QUENCHING MEDIUM, VARYING THE QUANTITY OF QUENCHING MEDIUM CONDUCTED TO SAID MIXING CHAMBER IN DIRECT PROPORTION TO VARIATIONS IN THE TEMPERATURE OF SAID MIXTURE OF COMBUSTION PRODUCTS AND QUENCHING MEDIUM SO THAT SAID MIXTURE ATTAINS A DESIRED TEMPERATURE, AND RELEASING SAID COMBUSTION PRODUCTS-QUENCHING MEDIUM MIXTURE TO THE ATMOSPHERE.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein the quenching medium conducted to said mixing chamber is a stream of air.
Claim 4
Dependent Claim
24 words
The method of claim 1 wherein the quenching medium conducted to said mixing chamber is a stream of a mixture of water and air.
Claim 5
Dependent Claim
38 words
The method of claim 1 wherein the step of varying the quantity of quenching medium conducted to said mixing chamber is carried out so that the temperature of the resulting combustion products-quenching medium mixture is less than 1000*F.
