Conclusion last project

Project A Bio digester with enough gas production for the energy demand of Zijldijk Electrical and heat generation and distribution to Zijldijk Compare the different possibilities

Energy demand in Zijldijk 1m 3 of natural gas cost € 0,67 the total consumption cost € kWh of electricity cost € 0,21 the total consumption cost €

Anaerobic digestion

Anaerobic digestion plant Gas holder Mix Digester Manure storage Gas engine

Digestion Controlled biological processes to involve treating organic waste using bacteria in an oxygen-free environment. The anaerobic bacteria produce a methane rich biogas by: Hydrolyze Acidification Methane production This biogas can be used to generate electricity

Diet of the digester

Biogas Natural Gas calorific value 35MJ/m 3 –Methane 80% to 90% Biogas calorific value 20MJ/m 3 –Methane 55% to 80% –Co 2 45% to 20%

Digestate Plants obtain the Nitrogen faster The digestate has an equal mixture Less fertilizer is necessary
