Special container for biogas plants
Containers manufactured by CHS Spezialcontainer – Shelter and Engineering GmbH for use as pump stations and control centres for biogas plants from WELTEC BIOPOWER GmbH have a long history of success. A biogas plant always consists of several components: one or more fermenters (the distinct feature of a biogas plant, in which the biomass is fermented), control systems (which control the introduction of biomass and forward the generated electric power and heat) and pumps (which are needed to transport the biomass and introduce water as well as for cleaning purposes).
This type of system converts renewable raw materials, such as maize, grass, organic waste, sewage, and animal waste into energy. During the process of power generation, a corresponding biomass (also called the substrate) is fed into the fermenter. The substrate is fermented and continuously stirred by a stirring unit inside of the fermenter. The methane produced during fermentation is then directly converted into electrical energy and heat in the integrated combined heating and power plant, which is basically an internal combustion engine that drives a generator. Alternatively, the methane can be processed further and delivered to filling stations or fed into the public gas grid. The material left over after fermentation is called the 'digestate'. However, this is by no means a waste product! The digestate can be used in agriculture as an environmentally friendly and effective fertiliser.
Our converted 40-foot containers have insulated walls as well as a partition wall with an integrated multi-purpose door. A side door provides access from the exterior to the control cabinet room, which houses the control electronics of the biogas plant. Next to this is the pump room, which contains mounting rails and numerous floor openings for installing pumps. Some of these floor openings are equipped with removable covers. This facilitates future enlargement and expansion of the biogas plant.
For one of our large-scale projects, we converted several 40-foot containers to allow the installation of heat exchangers. CHS Spezialcontainer converted these containers to include numerous openings in the side walls as well as in some of the roof structures. This enabled our clients to install the heat exchangers with a high level of precision.
