What is Biomass ?

Biomass is carbon based. In the context of biomass for energy this is often

used to mean plant based material, but biomass can equally apply to both

animal and vegetable derived material.

Biomass Basics

• Biomass Categories:

• Virgin woods: from forestry, arboricultural activities or from wood processing

• Energy crops: high yield crops grown specifically for energy applications

• Agricultural residues: residues from agricultural harvesting or processing

• Food waste; from food/drink manufacturing, preparation/processing, and post consumer waste

• Industrial waste and co-products: from manufacturing and industrial processes

12

Basic Carbon Background

• Plant Material (biomass): The carbon used to construct biomass is absorbed from the

atmosphere as carbon dioxide by plant life, using energy from the sun.

• Fossil Fuels: Fossil fuels such as coal, oil and gas are derived from biological material,

however material that absorbed carbon dioxide-CO2 from the atmosphere many millions of

years ago.

• Plant Material (biomass) vs. Fossil Fuels: the difference between biomass and fossil fuels is

one of time scale.

• Biomass: Takes carbon out of the atmosphere while it is growing and returns if as it is

consumed.

• Composting and Anaerobic Digestion are conversion technologies that consume carbon

• Composting: Biological decomposition of carbon done in the presence of air (oxygen

present)- no renewable biogas as a by product; not an energy producer

• Anaerobic Digestion: Composting without air (oxygen)- renewable biogas (methane-CH4)

as a product; is an energy producer

13

14

Anaerobic Digestion

It is the natural process that converts biomass to energy under oxygen free

conditions. The two most important considerations in converting the biomass

to renewable biogas are the input materials and the environment of the

bacteria (bugs) within the digester.

* Be careful of biological inhibitors that may be part of input

materials

* Approximately 60% of volatile matter consumed

* NPK unaffected and pass through

* Trace Metals unaffected and pass through

Renewable Biogas

Advantages

• Clear net posit ive carbon footprint

• Suitable for the development of

decentralized energy supply

• Digestion residues suitable for

premium fert ilizer

• Peak load capability

• Base load capability

• Power generation unrelated to

weather condit ions

• Generation of electricity

• Generation of heat and cooling

• Conversion to natural gas

Storable and AvailableMult ifunctional

OutputHighly Eff icient

• Highest energy recovery amongst

all biomass project types

• Use of the w hole crop in comparison

to other bio fuels

• Variety of feed stocks can be

processed (e.g. organic fuels)

EnviThan – Gas-upgrading with high-selective Membrane

35

• Membrane – a thin separation layer through which substances can penetrate in a limited

way

• Retentate – a by the membrane held back fluid (e.g. CH4)

• Permeate – a fluid that entered through a membrane (e.g. CO2)

• Selectivity – preferentially react or sort, it means separation of fluids

• Permeability – permeability or the flow through a membrane

• Separation-capacity – is a combination of selectivity and permeance and describes the

efficiency of a membrane

• Partial pressure difference – the pressure difference of the partial pressure of a gas on the

retentate (interior of hollow-fiber) and the permeate side (space outside the hollow-fiber) is

the driving force for the permeation

• Methane loss < 0.5 % possible, but about 0.8 % will be set for RTO

• Methane concentration over 97 % in the retentate possible

• Power consumption approx. 0.2 kWh/Nm³ raw-biogas

• Raw-biogas must be free of hydrogen-sulfide, ammonia, particulates, condensable material

and oil

• There is no need for water and the gas-upgrading works free of waste-water, apart from a

small amount of condensate from the cooling-process

• Output pressure is slightly below to the working pressure 11 bar absolute

• Modular structure of the gas-upgrading

• Small footprint

• No additional drying necessary

• It is possible to take heat back from the system (e.g. for the digester)

• Start-up time at full load in just a few minutes

• Partly-load operation is no problem, good controllability through pressure and volume-flow

• Low operational & maintenance costs

• No chemical- and heat-consumption needed

• Operating-pressure 11 bar absolute, operation temperature approx. 25 up to 28 °C
