IISc, Bangalore

Indian Institute of Science, Bangalore is one of the most prestigious institute in India which devotes their knowledge and expertise in Research and development. The Combustion, Gasification and Propulsion Laboratory (CGPL) at the Indian Institute of Science (IISc) , is involved in innovative research and developmental activity in the field of Bio‐resource in addition to frontier work in Aerospace propulsion. Besides fundamental studies, this laboratory has developed techniques of gasifying a wide range of biomass including agro‐residues. These techniques have been perfected into small independent power plants, which could serve thermal or electricity needs of industry or rural society. These technologies include H2S Scrubbing, Biomass Gasification, etc.

  • H2S is converted to solid Sulphur, which has commercial value.
  • No gaseous or Liquid emissions
  • Low H2S content in the cleaned gas (< 100 ppm v/v basis) irrespective of the inlet hydrogen sulphide concentration.
  • The system is capable of handling fluctuations in H2S concentration and biogas flow rate.
  • This process is highly selective for H2S with little CO2 being removed.
  • The system operates ambient temperature and pressure.
  • Easy start up and shut down.
  • Online removal of sulphur generated prevents choking/clogging of regenerator.
  • The chemical used is regenerated implying low running costs compared to other systems.
  • Tailor made for individual gas flow rates and inlet hydrogen sulphide concentration.
