The easiest is to wash the gas with water. Carbon dioxyde is very soluble (878 cm3/l at 20°C), unlike methane (34 cm3/l). This water carrying CO2 can be used for agriculture irrigation, or for algeas farming such as spirulina.

  • At the digestor exit, after the valve, create a gas circuit bringing the gas in a bubbler-reservoir.
