ABOUT US In 2010, NeoZeo AB was founded based on innovation at Stockholm University in Sweden. NeoZeo focuses on technological innovations in sector of sorbents for biogas upgrading to high quality biomethane. Based on its team’ vast research and engineering experience using novel sorbents for gas separation applications, NeoZeo utilises a combination of vacuum pressure swing adsorption (VPSA) technology and unique sorbents for biogas upgrading. Relying on best technological advances, the company developed its own compact biogas upgrading module for small- and medium-scale biogas flow rates. The flow rates from around 10 to 200 Nm3/hour are commonly produced from organic waste at farms, food waste companies and wastewater treatment plants. For more information or further inquiries about our biogas upgrading modules, please refer to the following contact details below.

OUR PRODUCT NeoZeo designs and manufactures biogas upgrading modules for production of high-value biomethane, with a focus on upgrading small- and medium- scale biogas flows (10-200 Nm³/hour). For bigger flows of biogas, NeoZeo offer having a few of the standard upgrading modules, which can be stacked together, reducing the total footprint. Another alternative is a skid-design made specifically for client’s project requirements. For more information, please feel free to contact us. An example of our biogas upgrading module is shown in Page 5 as a schematic 3D CAD drawing. The module has a 40-foot standard sea container size. The grey items within the container are components of the module. The module dimensions and sizes are listed below.

BIOMETHANE PRODUCTION PROCESS Raw biogas produced in an anaerobic digestion plant should undergo a local pre-treatment. Pre-treatment steps include the removal of hydrogen sulphide gas (H₂S) down to < 100 ppm concentration level and the cooling of the biogas down to optimum temperature and simultaneous removal of moisture from biogas saturated with water vapour. The biogas is then fed into the biogas upgrading module. Traces of H₂S (< 100 ppm) are removed with the activated carbon filter and the biogas is pressurized to 6-12 bar by a biogas (low-pressure) compressor. The biogas is further chilled, dried, puritied and collected in the receiver before it is supplied into the Upgrading Unit.

www.neozeo.com

The Upgrading Unit consists of several stainless steel (SS) columns, which are filled with NeoZeo’s novel and effective sorbent that separates carbon dioxide gas (CO₂) from the biogas, resulting in high quality biomethane.

During the biogas separation step, the sorbent is gradually saturated with carbon dioxide (CO₂) in one SS column. Then, the sorbent is regenerated with vacuum pump to be ready for next portion of biogas. The produced biomethane is collected at outlet of the Unit in the second biomethane receiver and ready for high-pressure compression. Biogas and biomethane quality is continuously monitored by gas analyser, which measures methane (CH₄), carbon dioxide (CO₂), oxygen (O₂) and H₂S concentrations.

The last step in the process diagram involves compression of the produced biomethane gas to high pressure of around 250-300 bar using a biomethane (high-pressure) compressor. This allows the produced biomethane to be stored in either stationary or mobile high-pressure storage units. The biomethane compressor and the storage units are located outside of the NeoZeo’s biogas upgrading module.

BIOMETHANE WEB PLATFORM

The Biomethane Web Platform project will aim to create a biomethane information and sales Web-Platform for biomethane producers together with an integrated User Application for biomethane end-users. This will allow the trading biomethane online in simple and cost efficient way. Additionally, the web-platform will help to increase decentralized biomethane production and distribution as well as further simplify, support and encourage the use of biomethane as renewable vehicle fuel in Sweden. The web-platform will bring together local biomethane producers (e.g. small and medium farms, waste management and water treatment companies), biomethane end-users (e.g. local taxi companies, municipal biogas bus fleets, municipal waste collection cars and trucks and private Natural Gas Vehicle car owners).
