While Anergy are able to construct the plant there are a number of things required for a project to successfully get off the ground. To assist with this, Anergy has developed this information guide so that developers are able to put together all the elements of a successful project.
Bulk and Dry Solid Densities |
Particle Size Distribution |
Form and Flowability |
Amount of Free Moisture |
Combustion Characteristics, including heating value |
Composition: Proximate and Ultimate |
The composition of the feedstock is usually reported as proximate and ultimate analyses. |
Moisture Moisture: Material is dried in an oven at 120 to 150°C, driving off any moisture as steam. |
Volatiles Volatiles: Material is heated to temperatures on the order of 500 to 900°C in an inert atmosphere such as nitrogen. Organic species volatilise and are removed from the sample. |
Fixed Carbon Fixed Carbon: The remaining solid material is heated in excess air or oxygen, causing combustion of the remaining carbon material to carbon dioxide.
|
Ash Ash: The remaining solid material, typically comprising silica and inorganic oxides. |
Different biomass materials can have widely differing proximate compositions. As shown on the ternary diagram, Anergy’s High Temperature Pyrolysis process can comfortably handle a vast array of different materials.
ElectricityElectrical Generation from the generators. |
Gate FeesA fee paid to take delivery of a waste product. |
Char/BiocharDepending on the feedstock there may be a value in the char product produced as a by-product of the HTP process. |
ActivatedCertain chars can be post-treated in order to manufacture an activated carbon which has many commercial applications. |
Heat/SteamSome industrial consumers may be willing to pay for heat collected from the exhaust of the engines or kilns. |
Government IncentivesIn certain jurisdictions then extra payments can be received from the government for either the production of renewable energy or from the reduction of waste. |
LabourThe biggest cost of running an Anergy HTP plant is the man-power to operate it. Operating hours and plant configuration can dictate the number of people required for this. |
Parasitic LoadThe plant requires some of the electricity that it produces in order to run the plant. This needs to be subtracted from the gross power output. |
FuelWhile Anergy HTP plants normally run off their own gas they do require a fuel for start-up. This fuel is typically diesel, natural gas or LPG but alternative fuels can be used as well. |
Maintenance & Spare PartsAll plants require spare parts and specialised service in order to keep operating. |
TransportationCost of transporting feed to the site and char away from the site. |
ConsumablesAll plants use certain quantities of consumables and these need to be assessed and valued. |
FeedstockSome feedstocks such as virgin biomass need to be purchased. |
Water Purchase/DisposalDepending on the plant set-up the plant could be a net user or consumer of water. Excess water needs to be treated and disposed of while a water shortage will need to be sourced. |
Char DisposalIn some cases, where there is no secondary market for the char then it will need to be disposed of to landfill. |
ComplianceDepending on the jurisdiction and operating permits there will be certain reporting requirements to legislative bodies. These carry certain costs and will need to be maintained. |
Additionally, however, Anergy is also able to provide Anaerobic Digestion for projects with a suitable environment and feedstock. Also, there are a number of different configurations of Anergy plants to handle various types of feeds and also to generate different products.
The Anergy Activation module can be added to suitable plants which can upgrade the char product produced to commercially saleable activated carbon.
Also, Anergy plants can be manufactured as containerised or fixed plant options depending on the needs of the location, feedstock and the scale of the plant.
Our applications engineers can work with you to recommend the best configuration for your plant given your plant profile and your budget.
Environmental analysis may need to be carried out taking into account:
Additionally, there may be processes required before the plant is able to be connected to a centralised grid which can involve a level of design.
These constraints and processes are very much driven by the local jurisdiction. Anergy is happy to provide generic information on these considerations. For more involved processes and depending on the data required then Anergy can be employed to give the technical components required for these areas of analysis. Typically, this should be done in conjunction with a local consultant to the project who is familiar with the particulars of the permitting.
