ETW Energietechnik: Biogas Processing Plant Successful in continuous Operation
After half a year of non-stop operation of the first biogas processing plant, ETW is pleased with the successful product launch of its new processing technology.
ETW Energietechnik: Biogas Processing Plant Successful in continuous Operation(firmenpresse) - For four years, biogas has been produced from maize, grass, and whole plant silage at the Laupheim site, about 30 km south of Ulm, Germany. The raw biogas is pro- cessed by Erdgas Südwest GmbH and made available to end customers in the form of biomethane over the own natural gas grid. In 2008, the first biogas processing plant was commissioned at the site. The pressure swing adsorption of Schmack Carbotech processes about 600 standard m3 of raw biogas an hour. This amount is sufficient to continually supply about 2,000 four-person households with electricity.
To respond to the growing demand for biomethane, the operator decided to expand the production capacity. In view of the practical experience from the operation and the knowledge of the advantages of dry pressure swing adsorption, the operator opted for a biomethane system of ETW Energietechnik. One of the main reasons for this deci- sion: The specialists from Moers, Germany, had the best solution for the challenge of integrating the new technology in the existing array.
Before the humid raw biogas enters the adsorption tanks, hydrogen sulphide is remo-ved and water is condensed out. The residual humidity is removed as a side effect of the pressure swing adsorption. The smart control by means of which the adsorption columns are connected ensures that the product gas purity reaches a stable methane content of 98 percent despite varying raw biogas compositions and quantities. Continual quality measurements guarantee short reaction times. Subsequently, the biomethane is forwarded to the feed-in station that serves as the interface to the natural gas grid with a pressure of about 6 bar.
For the first time, the plant in Laupheim generates biomethane with the PSA process control developed by ETW, which differs significantly from the established systems in Germany. The result is an extraordinarily high methane content in the product gas with minimal methane losses and rock-bottom power consumption. Thus, 98 percent of
the supplied methane can be delivered to the natural gas grid. The methane loss of 2 percent is returned to the biological process of the biogas plant via an after-burning unit in the form of useful heat. Together with the recovery of the compression heat, a total heat output of 140 kW at 80 Grad celsius can be separated from the gas processing.
With a power requirement of only 130 kW due to the optimised process technology and no need for additional supplies except active carbon for the desulphurisation, the operator benefits from a highly economic system.
The absence of self-inflicted problems such as heat requirements, fresh water requirements, winter conditioning, corrosion, sediments, channeling, and the handling of chemical substances makes for increased operational reliability and various ecological benefits.
The dry pressure swing adsorption of ETW Energietechnik will greatly stimulate the biomethane market. Especially as biomethane production is the only practicable method of storing renewable energy, it is up to the legislator to clearly define the role of biogas in the energy transition.

Unternehmensinformation / Kurzprofil:
ETW Energietechnik GmbH has been developing and producing energy plants in Moers, Germany, since 1997. The company‘s core business comprises the construction and maintenance of combined heat and power (CHP) plants in the output range of 200 to 2,000 kWel.
In 2011, ETW expanded its service portfolio with biogas processing plants for the generation of biomethane.
The company is a one-stop provider: From the transfer of biogas to the feed- in of power into the grid and the provision of heat, ETW also takes care of the construction, commissioning, and maintenance of CHP plants. Thus, bio natural gas can be used for energy production regardless of the location of the biogas processing, allowing the customers to concentrate on their core activities.
The clientele of ETW Energietechnik GmbH includes large energy suppliers, agricultural plants, municipalities, and industrial businesses of various types and sizes, all of which attach importance to eco-friendly, economic energy generation.
One of the strategic highlights is the implementation of economic, sustainable plant concepts that are planned individually and adapted to the respective requirements. A qualified service team ensures operational reliability and maximum availability of the plants.
Qualified team members, expertise, and years of experience form the basis for mature solutions for the utilisation of regenerative and fossil fuels such as biogas, landfill gas, sewage gas, and other special gases as well as natural gas and mine gas.
As a family-controlled medium-sized business, ETW Energietechnik GmbH is committed to a high level of social responsibility towards customers and employees. Since May 2005, the quality management has been certified according to DIN ISO 9001.
