Liquid processing involves several steps to ensure the quality and consistency is right. To ensure the appropriate removal of unnecessary gases from a liquid can be painstaking and expensive unless a company uses the right equipment. While the addition of chemicals can prove to be expensive, a more cost-effective alternative is installing a deaerator. Spray deaeration systems are one type readily available for beverage producers.
Types of Deaeration Systems
Some divide deaeration systems into three basic types:
1. Vacuum
2. Spray
3. Tray
However, another approach is to consider them as one of the two major types. These are:
1. Vacuum Deaerator (Degasifier): This type of spray deaeration system typically finds use for the removal of non-condensable gases such as oxygen, CO2 and N2 from a stream of liquid – often boiler-feed water.
2. Membrane Deaerator: In this system, fluid flows transversely from one side of a membrane surface. On the other side is a vacuum. This sucks out the gas allowing the liquid to continue
Both types of the above deaerators ensure the extraction of undesirable gases using a vacuum without the removal of the essential fluids.
Desirable Qualities
When looking at deaeration systems, it is important to consider the specific needs of your operation. This should help you decide what type is preferable. In general, however, the desirable qualities of such equipment include:
* Superior removal rate of the gases
* Durability
* Autonomist or, at least very little operational involvement
* Requires little space, i.e., compact
* Low maintenance requirements
* Cost-effective
These characteristics are essential when considering the purchase of any type of deaerator for your operation.
Spray Deaeration
When it comes to removing certain gases from liquids, chemicals can perform the task effectively. However, a more affordable solution is to install a spray deaeration system. Combining a spray system with the vacuum option effectively, efficiently and affordably ensures the extraction of unwanted gases.
