CLEAN-BGAS UPGR is a technology focused on biogas upgrading for biomethane Membrane separation: Based on the principle of the permeability of the 

Biogasupgrading by membrane 800 Nm3h Gasgrid injection. Membrane separation is one of the classical methods for gas upgrading. The membrane process is based on using permeable membranes to separate methane and CO 2. The first generation membranes required higher pressures (40 bar) and the efficiency was low.

Biogas contains carbon dioxide in the range of 35–45 vol %. Upgrading biogas to biomethane is primarily based on carbon dioxide removal. Biomethane is essentially purified biogas that contains at least 95 vol % methane and it can be either used as fuel for vehicles running on compressed natural gas (CNG) or injected into the natural gas grid. Nowadays, various techniques are used for CO2 We use SEPURAN® Green modules from Evonik Industries for the membrane separation process in our gas upgrading plants. These hollow-fibre membranes purify the raw biogas generated in the biogas plants from 50 to over 97 percent by volume – a very high figure compared with other technologies. BIOGAS UPGRADING AND UTILISATION 5 Biogas can be used for all applications designed for natural gas.

As biogas passes through a dense polymeric membrane, CO 2 is prevented from through-flow and removed, while CH 4 passes through. Membrane-based gas permeation systems consume only electrical power, but do not require any chemicals or water. Membrane separations are particularly appealing for biogas upgrading due to their lower energy consumption, good selec- tivity, easily engineered modules, and therefore lower costs.

Here we review biogas upgrading by membrane separation. We discuss gas permeation, membrane materials, membrane modules, process configurations and commercial biogas plants. Polymeric materials appear as most adequate for membranes aimed to upgrade biogas. Concerning membrane modules, hollow fibers are the cheapest (1.5–9 €/m 2). Multistage configurations provide high methane recovery, of 99%, and purity, of 95–99%, compared to single-stage configurations. After the pre-treatment of the biogas, the biogas is compressed to the necessary pressure for upgrading by membranes.

System operates at high pressure; CO 2 is easily recoverable near eliminating methane slip (loss) The system is simple, innovative and modular; The delivery pressure of biomethane is from 10-20 bar with a biogas input flow rate from 50-3,000 Nm 3 /h; Selective Solvent Biogas-Upgrading Plants Biogas Upgrading Using PRISM Membrane Separators Biogas is produced when organic materials decay. and release methane and carbon dioxide Controlled processes, like anaerobic digesters or collection lagoons, collect this biogas which is purified to remove the CO₂ and other inert gases leaving a purified stream of bio-methane. 2018-01-11 membrane configuration (extremely low methane slip, less than 1% possible) Ideal for small to medium plants from10 to 1.400 NCMH, easily scalable Excellent energy efficiency for upgrading (<0.2 kWel/Nm3 crude biogas, <0.4 kWel/Nm3 biomethane) Ease of maintenance Main advantages: BGX – Membrane … 2020-06-07 2015-02-17 2020-12-04 Membrane Biogas Upgrading Biogas is a combustible gas mixture that is produced by the fermentation of biomass. The typical fermentation substrate is sewage sludge, organic waste or food waste, manure, agricultural waste (such as cover crops, crop residues etc.), as well as specially cultivated energy plants (renewable raw materials). Evonik has developed a new membrane technology for upgrading biogas into biomethane.

Upgrading is key Clean gas is efficient gas. The biogas composition has a low heating coefficient because large volumes of carbon dioxide and water vapor interfere with the combustion process. A series of Air Products PB Membrane separators are used to upgrade the biogas into a The next step is to split the hydrogen molecules (H2) biogas upgrading.
