Ethylene Oxide and Propylene Oxide removal

page: Home > Applications > EO and PO removal

EO (Ethylene Oxide: C2H4O) en PO (Propylene Oxide: C3H6O) are extremely flammable and toxic components. Both on short as well as on long term, they act as carcinogens and mutagens. Because of these effects on mankind and the environment, very strict emission standards apply in many countries.

Use

EO and PO are important basic components in a multitude of organic syntheses, for example the production of glycols and higher alcohols. These glycols are used for the production of automotive anti-freeze, cellophane, polyester resins, synthetic fibers and rubbers, and hydraulic fluids.

Ethylene Oxide is also used as a sterilizing agent for medical equipment in hospitals and in the farmaceutical industry, Propylene Oxide is sometimes used in the starch industry for improving freezing applications.

Slow Reaction

Chemical reactions with these components take very long, even when a catalyst is used. A lot of other factors determine the efficiency of this reaction process, so technical know-how is required in order to design a reliable solution.

Efficiency

Using proprietary construction elements, patented technology, and an elaborate knowledge of chemical reaction mechanisms, BETE EO and PO scrubbers realize poluent concentrations below 1 mg/Nm³ (less than 1 ppm).

As a result, about 50 BETE EO and PO gas scrubbers are operational worldwide.
