Scrubber for Ethanol removal

Scrubber for Ethanol removalScrubber for Ethanol removalOne three-stage countercurrent scrubber installation (horizontal construction, outdoor arrangement), including three separate internally installed liquid buffers for the three washing sections of the scrubber, which is specially configured for a process gas flow with a maximum throughput of 1,950 Am3/h. The three separate washing sections are required to achieve a high ethanol removal efficiency from the gas flow. The installation is equipped with pumps, instrumentation and fittings.

The cleaned water-saturated gas is sampled via a probe mounted after the last washing section. The saturated airflow is drawn in through heated pipes to prevent condensation in the system. The molecules in the gas are exposed to infrared radiation. The ethanol molecules absorb some of the radiation. The absorption of the radiation is directly proportional to the concentration. The analyzer which is used is a infrared type.
