Evonik's SEPURAN® Green gas separation membranes help Germany's largest biogas plant produce bio-LNG

● Relevant biogas treatment parks can produce 9,000 tons of bio-liquefied natural gas (Bio-LNG) per year

● Adoption of carbon neutral fuels will advance the decarbonisation of the heavy cargo transport industry

● Evonik SEPURAN® Green gas separation membrane patented bonding process can improve production efficiency

German biogas technology company EnviTec Biogas AG uses Evonik SEPURAN® Green gas separation membrane technology for efficient biogas purification in its bio-liquefied natural gas (Bio-LNG) production
.
SEPURAN® Green is another typical application for the on-site production of renewable energy
.
EnviTec currently operates Germany's largest biogas processing park in Güstrow, Germany
.
From autumn 2022, the plant will supply 9,000 tons of biomethane per year
.
As a climate-neutral fuel, biomethane can be used in heavy-duty transportation
.

Purified products: liquefied biomethane and liquid carbon dioxide

In the future, the plant is designed to process about 500GWh of biogas and convert 150,000 tons of agricultural waste into high-purity biomethane
.
In addition, the carbon dioxide separated from the biogas can be used or stored as a natural feedstock after liquefaction
.

EnviTec has undertaken a multi-million euro renovation of its 31-hectare campus
.
SEPURAN® Green is used for the upgrade of bio-LNG production facilities
.
“We used a three-stage process developed exclusively by Evonik to connect the membranes for the most efficient biogas purification and to replace the outdated pressurized water scrubbing technology
,” said Olaf von Lehmden, CEO of EnviTec Biogas AG.
Chuang has cooperated for more than ten years, and has carried out biogas treatment projects of different scales around the world, accumulating more than 60 successful cases
.
"

Since the launch of SEPURAN® Green in 2011, Evonik and its partners have continuously optimized membrane technology and raised the quality standard of biogas treatment processes
.
In addition, Evonik is developing product applications for the on-site supply of biomethane, thereby contributing to the fight against climate change
.

Biomethane - mature technology for on-site supply

Biogas can be easily purified and refined into biomethane and used on-site as a climate-friendly fuel in the form of liquid (bio-LNG), shortening fuel transportation distances and reducing transportation costs, thus enabling green energy on-site Production and consumption nearby
.
In addition, such projects can also create more local employment opportunities
.

The transportation industry is striving to achieve climate neutrality goals
.
Compared with other alternative fuels, the use of biomethane as a fuel for transportation has accumulated many success stories and has a significant impact on the decarbonization of the freight industry
.

As a climate-friendly fuel, the environmental benefits of biomethane are clear
.
For example, bio-liquefied methane fuel vehicles have the following advantages:

● Compared with diesel and gasoline vehicles, CO2 emissions are reduced by about 90%,

● Particulate matter (PM) emissions are reduced by about 99%,

● Nitrogen oxide emissions are reduced by about 90%,

● Compared with diesel vehicles, the noise is reduced by about 50%
