2. Propane enrichment of Biomethane to make it suitable for
Injecting into the gas grid is an expensive process and
detracts from the ‘green’ credentials of the Biomethane.
Blending of Biomethane with pipeline gas
is an accepted means of reducing or eliminating the need
to enrich with Propane.
Variations of the following two methods of blending gas
are currently available:
3. ROV
In Pipeline Blending
Sample for GS(M)R
(excluding Wobbe)
Sample for
Wobbe only
Minimum
20
Diameters
*All potential gas feed paths may require analysis points (up and down stream)
*Expensive (land, excavation, communications etc.)
*Risk of large volume of non compliant gas to grid
4. ROV
ROV
Sample for GS(M)R
excluding Wobbe
Sample for
Wobbe only
Offline blending
*Essentially a full off take
and an entry connection (double metering etc.)
*means of motivating gas flow around loop required (compressor?)
*Means of controlling blend ratio required
5. A Tee Blender is a proprietary item that has
all of the advantages of offline blending
without the associated complications
6. ROV
Sample for GS(M)R
excluding Wobbe
Sample for
Wobbe only
Tee Blender
*Minimal non compliant gas to grid
*Inherent flow motivation around loop
*Blending proportional to flow
*Maintenance same as pipework
*No power supply
*No moving parts
*More efficient mixing (20D could be reduced)
