Abstract
A process is provided for thoroughly destroying dilute gaseous waste materials produced in an industrial manufacturing process by blending the same with a hydrogen-containing enrichment fuel stream. The resulting blend includes a sufficient amount of hydrogen such that at least 80% of the dilute gaseous waste material is converted to carbon dioxide and water vapor upon combustion at a flare.
Claims14
In a process for burning dilute gaseous waste materials in a flare, wherein said dilute gaseous waste materials require enrichment with a fuel source in order to convert at least 80% of the dilute gaseous waste material to carbon dioxide and water vapor upon combustion, the improvement comprises the steps of:
- a) providing a dilute gaseous waste material stream,
- b) providing a hydrogen-containing gas stream;
- c) forming a flare gas mixture by blending said hydrogen-containing gas stream with said dilute gaseous waste material stream in such relative proportions that the concentration of hydrogen in the flare gas mixture is sufficient to convert at least 80% of the dilute gaseous waste material to carbon dioxide and water vapor upon combustion;
- d) feeding the flare gas mixture to a flare;
- and
- e) combusting the flare gas mixture.
An improved process for burning gaseous waste materials in a flare, said process comprising the steps of providing a fuel stream and a gaseous waste stream, mixing said streams to form a flare gas mixture, and feeding the flare gas mixture to a flare, wherein the improvement comprises providing as said fuel stream a gas stream containing a sufficient concentration of hydrogen to convert at least 80% of the gaseous waste material to carbon dioxide and water vapor upon combustion.
An improved process of the type including a reactor process and a flare process, said flare process including the steps of mixing a fuel gas with a waste gas to form a flare gas and burning the flare gas, wherein said reactor process includes the step of employing said fuel gas in a chemical reaction, and wherein the improvement comprises reducing the quantity of fuel gas mixed with the waste gas by a first amount, increasing the quantity of fuel gas employed in the chemical reaction by a second amount less than or equal to said first amount, and mixing with said waste gas a substitute fuel gas containing a sufficient quantity of hydrogen to sustain combustion.
