Implication

Study demonstrates gas composition improvement in biogas purification using bittern and alkaline solutions, suggesting effective reduction of pollutants.

Key Points

  • Purification increased CH4 content above 80%, significantly enhancing biogas quality.
  • Magnesium and sulfate precipitation confirmed during CO2 absorption process.
  • Analysis conducted in a bubble column using titration and gas composition techniques.
  • Stepwise absorption method proved more effective than single absorbent use.
