CO2 Removal Solutions

The availability of methane as a green energy source points to the need for upgradation. Biogas Upgradation or enrichment in general terms is increasing the concentration of Biogas in the gas stream. The technology can be applied to cater for any demands such as heat generation in boilers, Bottling or grid injection. Methane loss and Purity along with cost are the major criteria for assessing the suitability of technology.

Biogas Upgrading Membrane System

Selective barriers are used in membrane technology to separate gases with the help of pressure differential. The viable pressure ratios are decided as a part of optimization by the OEM. The skilful engineering with ultra-selective polymeric membranes and the qualitative control system design is another advantage when choosing J&F Biogas for upgradation systems. We make sure the system caters to the demands of the client.

The desulphurized biogas passes through the containerised membrane modules post-dehumidification and conditioning. The separation guarantees a recovery of more than 97 – 99 % depending upon the stages of the membrane used. A relatively compact set-up with high efficiency and ease of operation is a commitment of J&F Biogas.

Features:

  • Operating Pressure range between 8 – 20 barg
  • Modular and compact system
  • Methane recovery between 97 – 99.5% and Purity as per IS standard to 99%
  • The Flow handling ranges from 50 – 3000 Nm3/hr

Pressure or Vacuum Pressure
swing adsorption

Vacuum pressure swing adsorption and pressure swing adsorption popularly known as VPSA and PSA eliminates carbon dioxide (CO2) in Biogas. The pressure-based technology provided by J&F Biogas is a practical and cost-efficient way to separate and extract CO2. The basis of VPSA and PSA is the adsorption and desorption of gases at different pressures.

The target gas such as CO2 is specifically adsorbed at designed pressure using absorption materials ie. zeolites. The molecular sieve zeolites used have excellent selectivity for Carbon dioxide. Once the pressure is released the gas gets desorbed. The technology has been widely recognised in the biogas sector over decades.

Features:
  • Operating Pressure range between 0.2 – 0.3 barg for VPSA
  • Skid mounted system
  • Methane recovery between 97 -99 % and Purity as per IS standard to 99%
  • Flowrates starting from 20 Nm3/hr
  • Lesser maintenance cost and Power consumption
  • Fully Automatic system

Solvent-Based
Biogas Upgradation

Selective absorption of gas by solvents from waste gas streams has been used popularly for gas separations. The solvents require designated pressure to dissolve solute gases. Once absorbed the process is reversed in a stripping set-up. The technology upgrades the biogas stream by removing CO2. The system can also be used where low-pressure injections are employed. A desired purity of around 99 % can be obtained in such systems.

Features:
  • High CH4 and CO2 purity
  • Low-Pressure Operation
  • Lesser Expenditure depending upon the solvent used
