EO/ETO Scrubber System
After ethylene oxide (EO/ETO) sterilization, the residual gas may not be exhausted freely depending on the exact environmental regulations of different countries and regions.
A scrubber system, which we also call a residual gas treatment system, will be needed to work with your sterilizer and aeration system on professional post-processing. This will ensure the final exhausted air from the scrubber system has been well treated and meets the emission requirements of your local environmental regulations.
Features of Our Scrubber
- Our team will offer professional services of consultation and design based on your particular project demands and local emission requirements.
- The scrubber system is for a multi-stage processing structure. The materials and components are made of acid & alkali resistant and anti-corrosion materials.
- Be capable of simultaneous treatment of EO gas discharged from multiple sterilizers and aeration systems.
Working Principle of Scubber
Sulfuric acid acts as a catalyst to form an acidic environment and promote ETO and water to fully react, and generate ethylene glycol. It is a multi-stage reaction, which is carried out in the multi-stage columns. The fully neutralized gas is discharged through a chimney. The discharged gas meets your local requirements of applicable environmental regulations.
Ethylene glycol is a non-hazardous chemical substance that is stable and safe. It can be recycled after neutralized with an appropriate amount of alkali, and there is no pollution. Ethylene oxide reacts with water under the catalytic influence of sulfuric acid to produce ethylene glycol as a by-product, and the chemical formula of the reaction process is as follows:
H2SO4 (catalyst)
C2H4O + H2O—————————————HOCH2CH2OH
