Indhold
The course will give the student a thorough insight into the production of biogas, including:
-
processes for the pre-treatment and bioconversion with a view to producing biogas from waste products, animal manure and agricultural crops
-
the degradation potential and energy yields of waste products and animal manure
-
basic understanding of anaerobic processes, process kinetics, inhibition, models, etc.
-
pre-treatment technologies including physical/mechanical (maceration, thermic), chemical (alkaline or acid hydrolysis), biological (silaging, addition of bacterial cultures or enzymes)
-
different reactor types, such as batch, CSTR, UASB, etc.
-
environmental balances using different biomasses.
Faglige forudsætninger

Læringsmål
On completion of the course the student should be able to:
-
explain the differences between operating methods of different reactor types, like CSTR (completely stirred tank reactor), UASB (upflow anaerobic sludge bed), batch etc.
-
describe a number of pre-treatment techniques and how they work
-
quantify the energy production from a given amount of biomass as it relates to chemical composition
-
explain the different biological processes and process kinetics of biogas production
-
utilise simple models to simulate the anaerobic process
-
discuss the essential parameters that inhibit the process (ammonia, sulphur compounds, heavy metals, etc)
-
calculate the dimensions of a biogas plant based on information on raw materials, raw material composition, retention time, temperature, etc. and reflect on methane yield
-
reflect on the technologies used for purification and upgrading of biogas for motor fuel and/or the natural gas grid
-
analyse the different options available in energy conversion, such as combined heat and power, motor fuel and fuel cells
-
calculate the impact on the greenhouse gas balance of the utilization of biogas technology
Bedømmelse
One written report and presentation to be approved prior to exam. 4-hour written exam with all means of aid including a PC without internet connection. The report and written exam counts equal.
External examiner, the Danish 7-point grade scale.
