Pipeline construction is a central aspect with biogas plants

Biogas plants have been continuing to grow in importance for several years in terms of the generation of renewable energy, and they represent a widespread possibility for the production of biological methane. Thermal energy is required for the fermentation the biomass; this is supplied by means of pipelines. A variety of media pipelines convey raw material and products to the corresponding users, and this is where the company Keil Anlagenbau has been able to step in and offer its assistance and support with its longstanding experience in the field.

 

We are very pleased to have received three orders from the company BioConstruct GmbH, a company for planning and installation of projects regarding renewable energy with its registered office in Melle, Germany, to install the entire piping system of three biogas plants in England with the total capacity of 1,5 MW. The facilities will function i.a. as methane gas feed-in plants and supply the total of 3.000 m³ methane in the general gas network. The business relationship with the company in Melle has continued for 10 years. At the beginning, this cooperation was limited to the switch cabinets that were to be integrated into the plants, but now the company Keil Anlagenbau also supplies the entire mechanical part including piping.

The installation started with heating pipes at the inner walls of the fermenter with a diameter of 21 m and a height of 9 m. The next step was to install the supply lines connecting all fermenters with each other, establishing a complex pipeline system. Last, the gas pipes were connected, to supply the gas network and the block heating stations with methane.

The great amount of welding work was a special challenge for the company Keil Anlagenbau because it was required for such an extensive project and it had to take place under adverse weather conditions, partly during heavy rainfall. Of course, in such a situation, a tent was provided for, so the welding work could be carried out in the open air. 

The special aspect of the projects can be found in the piping plans that were prepared by the company BioConstruct GmbH and prefabricated in our workshop in Bohmte-Hunteburg, Germany. During the planning stage, pipelines with diameters of DN 50 up to DN 300 made of various materials from stainless steel, plastics to black steel were considered.

The close proximity of both companies in the Osnabrück administrative district allows for short-term meetings, and/or inquiries that can be discussed personally on short notice in case of urgency.
