Deaeration & CIP Systems

Vacuum Deaeration

The Bevcorp vacuum deaerator is the most common form of deaeration used in meter-based blenders to achieve the lowest dissolved O2 value possible. The deaerator is a “Vacuum/Recirculation” type oxygen removal system with CO2 injection.

Advantages:

  • Can supply from .75 to 1.2 ppm O2 content, depending upon water temperature
  • Contains an atomizing diffuser in the water inlet to the deaerator allowing the water to give up most of the entrained gasses
  • The elimination of entrained gasses from the water facilitates CO2 absorption in the mixed product
  • Smaller footprint
  • Less installation cost
  • Deaerator and discharge piping are cleaned during CIP
  • Historical data trending and reporting

Membrane Deaeration

Membrane technology is a highly efficient way to remove oxygen from water when temperatures are below 45° F and its performance exceeds conventional vacuum deaeration.

Membrane contactors are capable of either removing or adding gasses to fluids. Membrane contactors contain thousands of micro-porous polypropylene fibers, knitted into an array and wound around a distribution tube. These are hydrophobic, so that gases flow freely while water will not pass through.

Advantages:

  • Oxygen removal is targeted at .75 ppm or less at maximum flow rates
  • Targeted oxygen removal is available at 34° F
  • Membrane modules are located within the existing blender frame without additional spacing required (results in a smaller footprint)
  • Typically reduced installation cost, with no additional electrical or process piping required

CIP/Deaerator Integration:

The Vacuum Deaerator has the capability of optional CIP functionality built into the same skid package. The existing vacuum tank becomes the CIP reservoir. The result on a conventional CIP system is a lower overall hardware cost limited to the heat exchanger with controls, the return and outlet temperature and chemical strength instrumentation. The operator interface is PC-driven with historical data collection and reporting.

  • CIP functions are built into the vacuum deaerator skid by permitting the existing vacuum tank to become the CIP reservoir.
  • Utilizes existing footprint, electrical and process piping connections and distribution pumps
  • PC-driven operator interface with historical data collection and reporting
  • Deaerator and discharge piping are cleaned during CIP
  • Smaller footprint
  • Lower installation cost

Audits

Bevcorp process engineers can audit your systems to identify equipment capabilities and deficiencies in blending units, service utilities and refrigeration systems.
