DEAERATOR PERFORMANCE TESTING

Is the plant deaerator system achieving maximum performance or is the plant using excessive amounts of sulfite chemicals to reduce oxygen content in the boiler feedwater system? The deaerator performance is a critical part of the steam and condensate system to prevent corrosion in the steam system. The deaerator operation provides a high-quality water for the boiler system, non-condensable gases removal and elimination, and ensuring a high steam quality for process applications. The deaerator performance is measured in units or parts per billion. Seven parts (7 ppb) per billion is the international standard, therefore the deaerator operating without sulfite being added for 48 hours needs to be operating at seven parts per billion dissolved oxygen level.
