New ETW SmartCycle biomethane plant in operation in France
IN April 2018, energy plant constructor ETW Energietechnik from Germany installed its first biogas processing plant in Scherwiller, France on a Rytec plant.
The plant has been in continuous operation since mid-April.
This is a compact model of the biogas treatment system ETW SmartCycle PSA developed by ETW.
With a processing capac- ity of 230 to 385 standard cubic metres of biogas per hour, this plant model has been specially developed for the French market.
Plant manufacturer Ry- tec from Baden-Baden is responsible for the entire project development and the installed fermentation line.
Biomethane on the ad- vance

France Marco Weiss said France is currently one of the most important mar- kets for biomethane plants in Europe.
“Biomethane is current- ly gaining ground in the neighbouring country,” he said.
“Energy experts assume that by 2030 France will be able to cover one-third of its gas requirements with biomethane.
“An essential prerequi- site for the implementa- tion, however, is the ap- plication of efficient and practice-proven process- ing technologies.
“In the recent past we had a strong demand for compact plants in the performance class up to about 500 standard cubic meters of biogas per hour.
“Together with our French partner GASEO, we have decided to in- tegrate our ETW Smart-
Cycle technology, already proven on larger systems, into a compact, flexible and energy-efficient con- tainer concept.
“In addition, this tech- nology will enable us to establish ourselves in many other markets with similar development po- tential.”
The compact design re- duces space requirements and assembly times on the construction site.
Flexible operation, self- regenerating process
Moreover, the flexible operation of the plant al- lows the operator to adapt directly to biogas produc- tion without having to ac- cept losses in biomethane quality.
The ‘smart’ process control reacts fully auto- matically even to large- volume flow fluctuations and changing raw gas qualities.
This means there is no loss in yield or quality of the biomethane produced.
The self-regenerating, dry gas treatment process has been continuously es- tablished in the industrial gas sector since the 1980s due to its extremely high availability.
With this property, the process is predestined for use in France.
ETW sales manager for Biomethane Plants Dr Oliver Jende said, “This is where biogas qual- ity is less predictable because large amounts of residues and waste end up in biogas plants.” “While in other systems an increased risk of ef- ficiency losses and plant downtimes can be expect- ed due to the presence of contaminants in the bio- gas, we can handle these conditions on the basis of our ETW SmartCycle
PSA technology.”
Low lifecycle costs
A high-quality industry standard paired with the special process advan- tages of the ETW Smart- Cycle PSA process, such as the lowest energy con- sumption of all treatment processes, results in the lowest lifecycle costs of all biogas upgrading pro- cesses available on the market.
“With more than 150,000 operating hours, our PPE processing sys- tems have a total availa- bility of over 99 percent,” Dr Jende said.
Plant operator Bernard Winterhalter is also op- timistic about the future.
With the support of Ry- tec, he has been work- ing intensively on various processing methods since 2016.
“At that time it quickly became clear to us that
we needed a dry process – simply because of the reduced operating costs compared to wet alterna- tives,” Winterhalter said.
“Therefore, only the membrane and PSA tech- nologies were available as options.
“However, it was just as important to the operator to minimise risks caused by possible impurities in such a way that the op- erator could ultimately choose substrates freely.
“Therefore, the PSA process convinced us not only because it systemati- cally regenerates, but also because the molecular sieve, due to its very high mass, is significantly less susceptible to impurities.” Second plant under con- struction
And so it is no coinci- dence that ETW Energie- technik and GASEO are currently building the sec- ond plant for the French market at Arcis-sur-Aube in the northeastern French department of Aube.
Here, the treatment ca- pacity will be 870 stand- ard cubic metres of biogas per hour from a waste fer- mentation plant.
The biomethane plant will be installed before the end of this year. Company profile
ETW Energietechnik GmbH has been develop- ing and producing energy plants in Moers, Germany since 1997.
The company’s core
business comprises the construction and mainte- nance of combined heat and power plants in the output range of 400 to 4600 kWel, as well as highly efficient biogas upgrading plants that produce pure biomethane out of raw biogas using a high-end PSA technology.
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, com- missioning and mainte- nance of CHP and biogas upgrading plants.
The clientele of ETW Energietechnik GmbH in- cludes large energy sup- pliers, agricultural plants, municipalities and indus- trial businesses of vari- ous types and sizes, all of which attach importance to eco-friendly, economic energy generation.
One of the strategic highlights is the imple- mentation of economic, sustainable plant concepts that are planned individu- ally and adapted to the respective requirements.
A qualified service team ensures operational reliability and maximum availability of the plants.
The medium-sized, fam- ily owned enterprise em- ploys a staff of 80 and is managed by its founder Helmut Weiss and his two sons Marco and Carsten.
