what is biogas
Combustible gas mixture (CH4, CO2, H2S)

Anaerobic fermentation preferred

Upgrading biogas

Increasing calorific value

Stripping CO2 and H2S

Input 250 m3/hr

Outline

Interim presentation MDP

boundary conditions
Simple model, only main parts are discussed

Waste streams are not modeled but are considered

The model starts with untreated biogas

The total input of energy and materials will be investigated

Costs of operating and investment will be estimated and be used to calculate the price per m3 of exit gas

Boundary conditions

chemical absorption pfd
Chemical absorption PFD

Interim presentation MDP

chemical absorption advantages disadvantages
Disadvantage

Scrubber needed to remove CO2

Advantages

Almost complete removal H2S

H2S converted into S

Chemical absorptionAdvantages & Disadvantages

Interim presentation MDP

water scrubbing pfd
Water scrubbing PFD

Interim presentation MDP

water scrubbing advantages disadvantages
Disadvantages

High amounts of H2S cannot be stripped

H2S is corrosive and will damage the scrubber

Advantages

High purity of CH4 can be reached

Removes both gases and particulate matter

Neutralization of corrosive gases

Water scrubbing Advantages & Disadvantages

Interim presentation MDP

pressure swing adsorption pfd
Pressure swing adsorption PFD

Interim presentation MDP

pressure swing adsorption advantages disadvantages
Disadvantage

H2S has to be removed prior to PSA

Advantages

High CH4-enrichment

Low power demand

Low level of emission

Pressure swing adsorption Advantages & Disadvantages

Interim presentation MDP

cryogenic separation pfd
Cryogenic separation PFD

Interim presentation MDP

cryogenic separation advantages disadvantages
Disadvantage

A lot of equipment needed

Advantages

Large quantities with high purity produced

No use of chemicals

Easy scale up

Cryogenic separation Advantages & Disadvantages

Interim presentation MDP

membrane separation pfd
Membrane separation PFD

Interim presentation MDP

membrane separation advantages disadvantages
Disadvantages

Membranes are expensive

Fouling

Advantages

Compact and light in weight

Low maintenance

Low equipment costs

Low energy costs

Membrane separation Advantages & Disadvantages

Interim presentation MDP

comparison
Chemical absorption gives a total removal of H2S but requires a scrubber for CO2 removal.

Water scrubbing is easy and has been proven profitable.

PSA is a rather complicated process but gives good results in practice.

Cryogenic separation will probably be very expensive and only profitable for high biogas streams.

A membrane plant is very easy to operate but could be expensive.
