Ethylene Oxide, (EO abator) - ETO Catalytic Abatement
LESNI continues to improve their "state of the art" balancer & catalytic abator solution for treating all ethylene oxide toxic vent emissions from the sterilisation process of medical devices.
The Balancer-Catalytic abator system uses the proven technology of catalytic oxidation to offer a safe and controlled purification, but with high destruction efficiency exceeding 99.95 % for all EO vents; from vacuum pump exhaust and all other fugitive exhaust air generated during the sterilisation process from degassing cells and aeration rooms.
The LESNI unique and safe system has two steps:
In the first step a "water balancer" is used to dampen the peaks and expected variations in the incoming quantity of ethylene oxide from the vacuum pumps. So when the incoming concentrations of EO are high, the balancer will serve as an absorber; and when incoming concentrations of EO are low, a unique but controlled stripping of EO will commence, thus providing a constant and continuous VOC load to the catalytic abator in a safe and efficient manner to reduce running cost.
The second step of the plant is the catalytic ABATOR itself, where the EO is converted into CO2 and H2O, this is encouraged at low temperature by the special catalyst used.
The energy needed for preheating the air can be provided through a gas burner, flameless electric or steam heater.
The energy costs are substantially reduced by the incorporation of a recuperative heat exchanger. An automated operator touch panel and plc in the switch control panel will povide remote operation, trending and supervision of the plant once installed.
The ethylene oxide abatement system will be designed to obtain the purification required by the authorities (as low as 0.5mg/m3) with the highest degree of security and efficiency.
