Scrubber for reduction of ethylene oxide

A complete scrubber installation consisting of three vertical columns, including integrated liquid buffers, which is specially configured for a process gas flow with a nominal throughput of 30 - 150 Nm3/h.

First and second stage acid scrubber (H2SO4)

The contaminated gas enters via a side entry at the bottom and then passes through a packed bed of random packings where washing water with dissolved sulfuric acid (H2SO4) is distributed by means of a sprayer to be able to wash out EO and PO.

Alkaline scrubber (NaOH)

The contaminated gas enters the third stage via a side entry at the bottom and also passes through a packed bed of random packings bodies. However, washing water containing dissolved caustic soda (NaOH) is distributed over this.
