Economical landfill gas treatment

28.11.2014

On-site regeneration of activated carbon for gas treatment

Landfill gas sourced from landfill sites and sewage treatment plants can also be burned in combined heat and power plants and used for energy purposes in place of conventional natural gas.

To prevent premature wear to turbines and motors, however, the gas must first be cleansed of undesirable impurities such as organic silicon compounds. The BINE Projektinfo brochure “Clean use of landfill gas” (11/2014) presents a method by which the adsorption agent is regenerated on-site.

Consequently, the activated carbon must be exchanged less frequently. The objective is to reduce costs and to make the process of gas purification more efficient.

Adsorption with activated carbon and subsequent regeneration is the most common procedure followed in gas purification. Siloxa Engineering AG together with Fraunhofer UMSICHT have developed an on-site regeneration method for activated carbon through adsorptive purification.

The procedure has undergone testing in field trials at the Vereinigte Ville landfill site in Erftstadt-Liblar near Cologne. In order to additionally reduce the load of polar organic compounds such as trimethylsilanol, the researchers recommend a process of pre-purification by means of seepage water washing.

The research group developed a theoretical procedural concept for a gas purification plant with a throughput of 1,000 Nm³ per hour: For this concept, the research team also produced an operating costs analysis for an average silicon load present in the landfill gas.

Based on this information, the researchers’ calculations determined there to be a considerable advantage in the new method in terms of specific operating costs over a conventional adsorption system involving the exchange of activated carbons. Further tests are needed under boundary application-like conditions to develop the market viability of the on-site method.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
