Biogas water scrubbing
WebScrubbing system consists of the Water scrubber with iron wool packed bed connected to a 500 litre water tank, and two tyre tubes which were used in storing the pre scrubbed (raw) biogas and the scrubbed (purified) biogas. The water scrubber has an inlet for the entry of the raw biogas and a discharge for the exit of the scrubbed biogas. WebJun 1, 2024 · Water scrubbing removes CO 2 from raw biogas but simultaneously it is effective at removing H 2 S thus yielding high purity biomethane with a simple biogas purification plant. However, H 2 S may be released to stripping air requiring additional treatment of large amounts of air containing diluted H 2 S leading to high costs per unit of …
