AIRRANE is a leading pioneer of innovative membrane solution technology for gas separation. From hollow fiber membrane production to the design, manufacturing and servicing of membrane modules and separation system, AIRRANE’s goal is to serve as your one-stop provider of advanced membrane technology for gas separation.
AIRRANE for Biogas:
Biogas has continued to grow as a next-generation energy source; it is a clean, renewable alternative to natural gas for gas grid, power generation, or even motor fuel. Usually obtained from the anaerobic digestion of organic matters at waste processing plants and landfill sites, biogas requires additional refinement to increase the concentration of methane (CH4). AIRRANE’s membrane separation technology offers a cost-effective solution with high methane recovery rate which makes biogas an efficient and affordable source of renewable energy.
Key Applications:
• Food Waste Processing Plant
• Landfill Site
• Waste Water Processing Plant
• Waste Management Facility at Brewery
• Slurry & Manure Processing at Farms
• Crops and Residue from Agricultural Production
Membrane for Biogas:
• Does not require frequent replacement of chemical ingredients
• Can operate in mid-pressure process (under 10 barg)
• Less pressure loss
• Simple operation and low maintenance requirements
• Flexible operation allows for running adjustment
• Possible to install for small-scale operation
• Small foot-print
• Easy up-scaling
Gases which permeate faster and more are collected outside of the hollow fiber as permeates while gases which do not permeate so well and stay inside of the fiber until they reach the other end are separated out as retentates. Depending on the properties of the desired gas, either or both of Bio methane Upgrading Technology permeates and retentates can be used.
The permeation rates of different gases and vapors also vary according to the types of polymers used to make membrane fibers. Carefully controlling the material of membrane varies the sorption-diffusion mechanism through the membrane which determines the permeation rate through it. Oxygen Concentration Membrane
The permeation rate of each gas is determined by its solubility in the membrane material and its diffusion rate. Gases with higher solubility and smaller molecules (fast gases) can pass through the membrane faster than other less soluble gases with generally larger molecules (slow gases).
