Ethylene oxide (EO) is widely used for the production of poly glycol ethers and the sterilisation of heat-sensitive tools and equipment.
In recent years, our Trevi R&D division has developed a new scrubbing concept for EO that eliminates the need for the periodic replacement of the acid scrubber liquid. This has multiple advantages: lower operational cost and waste production, higher safety etc.
For small gas flows (4-40 m3/h), a liquid jet gas ejector scrubber can be applied as a scrubbing technique, for example at gas filling stations. A bubble reactor and gas jet liquid ejector scrubber can also be used for specific applications of EO abatement.
A dry scrubber can be applied for the abatement of low concentrations of EO in fairly small gas flows. Our Trevi R&D division has also developed a biological waste gas technique (biofilter) for the abatement of high volumes of low concentrated (< 100 ppmv EO) air flows, as can be seen in aeration rooms at EO steriliser facilities.
