Biogas Refinement

Raw biogas is humid and warm and with only 50-54 Vol% methane it has only the half calorific value of natural gas, but 100 to 300 ppm hydrogen sulphide. The HAASE BiogasUpgrader increases the methane percentage inside the gas to 90-98 Vol% (adjustable values) and eliminates at the same time sulphur and water vapour. The processed biogas can be applied as motorcar fuel (biogas petrol station Jameln, Rathenow) or for power generation by CHP at another location or feed in the local natural gas net (Ronnenberg, Rathenow).

The procedure works with an organic cleaning dilution. The cleaning dilution bonds carbon dioxide, hydrogen sulphide and water vapour by means of pressure and at low temperatures. The gases are desorbed by relaxation and heating.

The technical and economical advantages of the BiogasUpgrader compared to other standard procedures are:

High availability  Little emissions Optimal energy balance

Two aspects for the energy balance: The organic cleaning dilution is regenerated and circulated. The produced heat quantity is sufficient for satisfying the heat-basic load requirement of a biogas plant nearby. Thus biogas plant and BiogasUpgrader operate together as ideal 'energetic symbiosis'.

The methane emissions of the BiogasUpgrader fall below 2 Vol%. Furthermore it is possible to realise a 'zero-methane-concept' by retrofitting a HAASE VocsiBox^®. This is an important aspect for climate protection, as methane is 21 times more harmful to climate than carbon dioxide.

The high availability of the BiogasUpgrader is proven: The BiogasUpgrader in Jameln has been in operation since June 2006 and operated more than 17,000 operational hours within this two years.

The first German biogas petrol station was officially established by the Raiffeisen-Genossenschaft Jameln (Wendland) on 22 June 2006. There the HAASE BiogasUpgrader upgrades the biogas from the local biogas plant to motorcar fuel (biomethane). 100m³/h biogas are diverged from the biogas plant in Jameln (operated by renewables and manure) for the production of fuel.

The feed-in of bio-natural-gas to the local natural gas net is most meaningful solution for many locations and will gain in importance in future. Experts consider net supply of biogas as key technology for the biogas sector. Therefore HAASE Energietechnik offers the plant technology.

The BiogasUpgrader in Ronnenberg ordered by enercity (Stadtwerke Hannover) has successfully been feeding 650m³/h biomethane in the natural gas net of the Stadtwerke since March 2008. The biogas plant Ronnenberg offer approx. 2.4 million m³ biogas for preparation and feed-in. This is sufficient for supplying about 1,400 households with heat. The order was placed in the frame of a EU tender. (Further information please find in the download area on the right and under News on this website.)

4.7 million m³ bio-natural-gas will be feed in the NBB natural gas net in Rathenow (Brandenburg). The order for the biogas preparation plant was placed by GreenGas Produktionsanlage Rathenow & Co. KG. The construction phase on site will start in December 2008. The BioagsUpgrader Rathenow will produce hourly approx. 520m³ bio-natural-gas from approx. 1,130m³ raw biogas. This complies with the energy requirement of 2,000 single-family houses for thermal heat and hot water.

The bio-natural-gas will be fed in the public net of the gas net operator NBB by a 2.2km long transmission line. More than half will be filled into tanks of environmentally friendly natural gas cars in Berlin and Brandenburg, which fuel at 15 natural gas stations of the GASAG Berliner Gaswerke AG and the EMB Erdgas Mark Brandenburg GmbH. The rest is supplied amongst others to the Stadtwerke Hennigsdorf for power generation in a CHP on the planned BioCampus.
