A new and effective chemical absorption process for removal of Hydrogen Sulphide gas from Acid Gases / Hydrocarbons / Industrial Influent and/or Effluent gases, which is extremely important to deal with due to its corrosive nature, danger to human health (HSE Concern) & bad odour. The process invented is based on the principle of chemical absorption whereby acid gases which includes H2S and CO2 gases are treated with special type of chemicals (a new invention invented by Charuchandra Dewasthale) giving clean gas with less than 3 ppm of H2S in treated gas irrespective of inlet H2S concentration.
