Digester Plant Design

Design Parameters (1)

•Proven technique/technology (simple and robuste)

•Operation during day-time and year around

• 4 operators

•100.000 t/a biomass

•4 digester tanks

•1 2e digester

•16 milj nm3/a biogas 10 milj nm3/a green gas

• Subsidy for Production of sustainable energy: SDE-

subsidie op 9 milj nm3

• Digestate: processed to organic fertilizer

14

Design Parameters (2)

•Proven technique/technology (simple and robuste)

• Low E-energy consumption

• Low heat losses

• No additives unless …..

• Take enough time, look around en make up

your mind, because it’s your money:

15

16

Digestion: revenu’s

•SDE green gas

• Commodity price for natural gas

• subsidy

•Green Gas Certificates (Vertogas)

• Supply chain feedstock and origin

• Traceability

• Mass balance = energy value

17

Biomass 100 % vegetable origine !

•Restproduct from Processing of Sugar Beet

• Beet tails –leafs

• Pressed pulp: surpluss production

•Divers:

• Potato industry

• Food industry

18

Feedstock Digester divers

Quality Requirements Feedstock

•Fertilizer Legislation

• Digetate: Fertilizer yes/no

•SDE: sustainability:

• Categorie overige vergisting

•Vertogas: • Biomass balance

• Biomass energy to the grid

•NTA 8080

•Gas Quality Green Gas

(fe Wobbe-control only by CO2)

Digestate

26

Digestate (1)

Per module 100.000 ton/a

• 80.000 ton liquid fraction

• 10.000 ton cake

• Centrate

• Water purification

• Concentrate (NPK; 12,5,5)

Composition of Digetate:

• Fiber (organic matter)

• K, Na, P,N

Digestate treatment

27

Dekanter Centrifugal

evaporator

• Operation Until now: (1)

•Feedstock: purchasing certified products: (professional

suppliers)

•Operation;

• Staff is ok

• Biology no problem

• Maintanance: 2.5%

•Digestate:

• Higher costs: flocculant and maintanance dekanter

(=feedstock)

• Market: constant quality

28

Design Parameters (2)

•Proven technique/technology (simple and robuste)

• Low E-energy consumption

• Low heat losses

• No additives unless …..

• Take enough time, look around en make up your mind,

because it’s your money:

29

• Operation Until now: (2)

• Green Gas:

• Advancing insights Grid Opererators

• New spec’s (fi Wobbe) extra investment

• Feed-in fee (interpretation of code; one direction)

• High costs on Gatekeeper (GC)

• Learning curve on Gasupgrading (2 years)

• Neighbours:

• local residents are becoming increasingly critical

• Despite of informing people,

• Biogas sector reputation

• NIMBY

• The Alternative which not excisting is favorit

30

Other;

•Biogasinstallations on industrial area?

• Scale

• No “neighbours”

•Which scale is optimal?

•Gas or E?

•CO2 as product?

•BioLNG?
