What is PD CEN/TR 17238 - Proposed limit values for contaminants in biomethane based on health assessment criteria about?
PD CEN/TR 17238 explains an approach for the assessment of limit values for contaminants that may be found in biomethane. Limit values are generally required as an adjunct to a biomethane specification (such as parts 1 and 2 of EN 16723, or an equivalent National specification) or as part of a Network Entry Agreement for injection of biomethane into gas networks.
The methodology as specified in PD CEN/TR 17238, when employed will permit derivation of limit values based solely on consideration of the potential for impact on human health and does not consider other impacts, such as integrity and operation of plant and pipelines used to convey biomethane or appliances involved in its combustion or other regulations like CLP regulation. Where a consideration of such impacts would result in proposing lower limit values than those based on health impacts, then the lowest limit values should generally be proposed.
Who is PD CEN/TR 17238 - Proposed limit values for contaminants in biomethane based on health assessment criteria for?
PD CEN/TR 17238 - proposed limit values for contaminants in biomethane based on health assessment criteria is useful for:
- Petroleum industry
- Health risk assessment authorities
- Environmental impact assessment agencies
Why should you use PD CEN/TR 17238 - Proposed limit values for contaminants in biomethane based on health assessment criteria?
Biomethane can be produced from biological (fermentation, digestion …) and thermochemical processes and it is essential that it is appropriate to be used as a blending component to natural gas.
PD CEN/TR 17238 aims for the development of a set of quality specifications for biomethane to be used as a fuel for vehicle engines and to be injected in natural gas pipelines (network).
One of the aims of European policy in the field of energy is to increase the security of energy supply in the EU as well as to contribute to reducing the emission of greenhouse gases accepted by the EU at Kyoto. In this context, PD CEN/TR 17238 gives special focus to the development and use of energy from renewable sources and their impact on heath.
PD CEN/TR 17238 provides general guidance on the assessment and selection of HCVs which allows you to determine Health Criteria Values (HCVs) obtained for each contaminant in biomethane.
