Biomethane The sustainable alternative RENEWABLE FUEL WITH POSITIVE CHARACTERISTICS FROM BIOGAS TO BIOMETHANE STOREABLE & TRANSPORTABLE Biogas is produced naturally through the anaerobic digestion of organic waste and residues. The biogas produced, also called raw gas, is first subjected to pre-treatment which removes impurities from the biogas input before it enters the compressor and separation membranes. It includes gas drying, activated carbon filter and pre-compression. Biomethane can be fed into the natural gas grid and be transported through it. This makes it possible to use it far away...

agriPure® The system for biogas upgrading YOUR BENEFITS AT A GLANCE A PERFECT SYSTEM The innovative and sustainable agriPure® biogas upgrading plant was originally developed by agriKomp in 2015. The biogas upgrading process converts biogas produced by anaerobic digestion into biomethane using special membranes. There are several pre-treatment steps to clean and condition the biogas. The biogas is then compressed before entering the membranes which are used to separate the methane (CH4) and carbon dioxide (CO2) gases at a molecular level. After this upgrading process, the product biomethane can...

agriPure® Pre-treatment and housing Pre-treatment Activated carbon Filter Compression Volume flow Biogas Biogas Pre-compression Heat recovery Retentate Biogas plant Heating container 1. COOLING / CONDENSATE REMOVAL HOUSING (CONTAINER) The raw gas (biogas) from the biogas plant will be fed into the pre-treatment. First step is the cooling of the biogas and separation of condensate. The gas is cooled and dried before entering the desulphurization unit. This extends the life of the activated carbon and of the compressor, which are high cost components. Desulphurisation, as the 3rd step of the pre-treatment...

Gas purification and membrane separation MEMBRANE MODULES As a highly efficient solution for biogas purification, agriKomp uses EVONIK Sepuran® Green membrane modules. Gas separation membranes operate according to the principle of selective permeation by a membrane surface. Selective permeation The difference in size and solubility of biogas molecules leads to different permeation rates through the membranes. While carbon dioxide or water passes through the membranes at a fast rate, methane is retained (slow diffusion rate). The three-stage purification technology allows purifying performance...

agriPure® Further important components FURTHER COMPONENTS HEATING SYSTEM HEAT RECOVERY SYSTEM The upgrading plant control system is substantially automated, ensuring safe and convenient operation. Operator intervention is minimal and generally limited to routine daily inspections and attention to any notifications of operational disturbance. All essential components and sub-controllers are linked with the main plant control and diagnostics and system maintenance activities are possible via remote access. The agriPure® heating system is a ‘plug and play’ containerised boiler system with integrated...

Case Study The 1st biomethane plant with CO2 recovery in France THE PROJECT Four agricultural farms have come together near Nantes to found the operational company SAS Métha Treil: two livestock farms and two vegetable farms. For the implementation, SAS contracted agriKomp, which realised all processes of biogas production, pre-treatment and upgrading to biomethane in a complete solution. "Having a single supplier for the design and construction of the plant guaranteed us a single interface and avoided finger-pointing between the installers of the different works in case of disputes," comments...
