Product Description

VALODOR: Gas Odorisation System

Prodeval offers VALODOR, a gas odorisation system. Biomethane is odorised using the by-pass method, by running the gas through a tank containing a liquid odorant. Ensured by the difference in pressure both upstream and downstream of the apparatus, the biomethane flow rate does not necessitate a pump and therefore there is no energy cost involved. The final concentration of THT injected in the biomethane is regulated continuously by an automated system.
