ISO DIS 22580
Flares for combustion of biogas
|Publication Date:||18 January 2019|
|ICS Code (Biological sources and alternative sources of energy):||27.190|
This international standard applies to the design, manufacture, installation and operation of flares for the combustion of biogas. Test methods and performance requirements are also included.
Biogas systems are amongst others applied at industrial plants like food and beverage industries, waste water treatment plants, waste plants, landfill sites, small scale plants next to agricultural companies and small scale household systems.
Explanation of the scope
Biogas is normally a by-product produced by amongst others modern wastewater treatment plants, food & beverage plants, livestock farms and organic waste. The main ingredients are approximately 50 ~ 65 % of methane and approximately 30 ~ 50 % of carbon dioxide and also contains many other ingredients, such as water vapor, hydrogen sulphide, ammonia, nitrogen, oxygen, siloxanes, and hydrocarbons. Methane is one of the main initiators of the greenhouse effect. Biogas will not only pollute the environment, but also causes serious potential safety hazards. Therefore centralized processing of anaerobic methane is needed. In case the biogas output cannot be used to generate energy or upgraded to biomethane, because of economic reasons or in case the energy production installation does not work properly, the biogas or biomethane is collected and combusted in a flare. The methane percentage of biogas or biomethane to be combusted in a biogas flare can vary from 5 % to (almost) 100 %. Biogas flares have the function of improving workplace safety, increasing the social identification, reducing the odor pollution and reducing the greenhouse effect.
For the utilization of biogas to generate energy (e.g. boilers, power generation, biogas upgrading et cetera) is referred to the Working Draft of a standard under development in TC 255 working group 5 [include the document number later after this is known]. In this draft standard is also mentioned in which cases a flare has to be applied.
