The emission requirements for catalysts for use in the biogas sector have increased significantly in recent years. Biogas as a fuel presents a particular challenge for catalysts, and the hydrogen sulfide content in particular must be reduced with the aid of reliable gas treatment. Even low concentrations of hydrogen sulfide can poison the catalyst and thus significantly shorten its service life.
All Emission Partner catalysts are designed to safely comply with 20 mg/Nm³ of formaldehyde, and in combination with an emission measurement organized by us through an accredited measurement institute, we guarantee you a passed emission measurement.
You have questions…
…on the subject of oxidation catalysts for your biogas CHP or on the subject of emission measurements?
Then get in touch with us, we will be happy to help you.
In order to receive the emission reduction bonus, plant operators must now fall below a formaldehyde limit value of less than 20 mg per standard cubic metre and carry out an accredited emission measurement every year. This emission requirement determines the catalyst technology for biogas engines in Germany, a high formaldehyde conversion with long service life and robustness against impurities in the biogas at the same time.
CATALYST FOR ELEKTRO HAGL MOTORS
This catalyst is flanged directly into the exhaust pipe downstream of the turbocharger and has a baffle plate that significantly improves the gas inflow onto the catalyst surface.
This catalyst is inserted directly into the heat exchanger at the hot gas inlet side. The flexible lamella spring brim reliably prevents gas slippage past the catalyst.
Catalysts from Emission Partner for your SCHNELL engine are available directly from SCHNELL. The catalytic converter can be replaced in less than an hour thanks to the exchange system. The formaldehyde limit value is undershot for at least two years.
Catalysts for 2G agenitor engines
Agenitor engines are characterized by high electrical efficiency combined with high formaldehyde emissions. The additional installation in the heat exchanger head requires very high demands on the tightness of the catalyst to the heat exchanger inner wall and on the conversion performance. Emission Partner has developed a special catalyst for these engines with a flexible lamella spring brim for reliable sealing against exhaust gas slippage and with a particularly long catalyst matrix. The catalyst is available for the engines agenitor 206/306/406/406/208/212 and 312. All catalysts comply with the strict formaldehyde limit of 20 mg/Nm³.
CATALYSTS FOR MDE/MTU, engines series 400
MDE units are cogeneration units derived from MAN engines with relatively low raw emissions and a large catalytic converter flanged to the exhaust gas heat exchanger. Due to its construction, this design has no slip compared to the AWT plug-in unit. These engines can also be operated without gas treatment using sulphur-resistant catalytic converters specially developed by Emission Partner.
CATALYSTS FOR JENBACHER
Jenbacher engines, especially the Jenbacher 312, are very popular with German biogas producers due to their reliability. These engines are characterized by relatively high formaldehyde raw emissions, which pose a special challenge to the catalysts. Depending on the location of the installation, Emission Partner has developed its own catalyst line that reliably complies with the strict German formaldehyde requirement over several consecutive measurements
CATALYSTS FOR MWM
Due to the many CHP manufacturers (SEVA, Pro2, ETW, Dreyer and Bosse) who have installed MWM engines for biogas operation, there is no uniform catalyst for these engines (mostly TCG 2016 V12/V16). Because the conversion requirements have increased, it is advisable to install a catalyst chamber with two thin catalyst discs, which can be individually cleaned and replaced as required.
New Flex cogeneration units must already be equipped today with an SCR retrofit solution
From 01.01.2023, the 44th BImSchV requires nitrogen oxide emissions to be reduced to 0.1 gr/Nm³ for all new biogas engines, which go into operation after 20.01.2018. For operators who want to make their biogas plant more flexible, this means that they must in any case provide for the operation an SCR exhaust gas treatment unit for their new Flex CHP plant.
Emission Partner has developed a compact SCR exhaust gas system in cooperation with its partners Adam and enkotherm, especially for container CHP plants, which can be mounted on all common Flex CHP power classes.
