Intensified deaeration by means of Rotating Packed Beds

Metal piping and equipment corrosion related to the presence of oxygen is a severe problem in the industry. It may lead to longer down times or a replacement of the equipment, as a consequence additional maintenance effort increases the production costs.
Commonly used equipment types for the deaeration in the chemical industry are (bulky) vacuum tower de-gasifiers or forced draft degasifiers.
However, acquiring the necessary low oxygen concentrations is challenging.
Application of Rotating Packed Beds (RPBs) allows for a high removal rate of oxygen for less than <50 ppb
Equipment size reduction by a factor of 6 to 9, due to the increased volumetric gas-liquid mass transfer rates.
