Biogas Burner

  • Biogas generated from palm oil mills can be to good use as fuel for boilers or heating tunnels for rubber or coconut copra.
  • GSE burners are equipped with the following 7 components:
    • Burner
    • Gas Train
    • U-Seal
    • Moisture separator
    • Gas Blower
    • Combustion Air Blower
    • PLC Control System
  • With the PLC System and HMI real time process is available for process engineers to monitor

Biogas Scrubber

  • Our Bio Scrubbers are made of fibre glass and can be customized based on different capacities. We offer full turnkey solutions.
  • The media used in the Bio Scrubber is polyethylene (PE) –Flower Type
  • The Bio Scrubber operates on a counter current flow where the biogas enters at the bottom of the scrubber and flows upwards against the flow of water from the top of the scrubber.
  • In this counter flow, the hydrogen sulphite levels can be reduced to as low as 150ppm

Biogas Enclosed Flares

  • We supply Biogas Enclosed Flares on a turnkey basis.
  • Enclosed flares provide a more controlled combustion process by containing the flame within the combustion chamber.
  • This design improves safety, reduces noise and lowers emissions
  • Concealed flame reduces visibility concerns
  • Suitable for populated or environmentally sensitive areas

Compressed Bio-Methane Gas

CBG

  • Our Compressed Bio-Methane plants uses the membrane technology.
  • Membrane module is made of stainless steel cylinder containing hollow fibre membrane cartridge inside.
  • Biogas (feed) comprising methane, carbon dioxide, nitrogen, oxygen and moisture enters the membrane module and the biogas is upgraded from 52% methane levels to about 95% methane level called “retentate”.
  • Carbon dioxide and other gasses called “permeate gas” are removed.
  • Incoming Hydrogen Sulphite of 200ppm max can be reduced to as low as 23 ppm in the CBG.
  • The CBG will be compressed and stored in pressurised cylinders and can be used in vehicles or domestic use.
