Series 820 Decarbonator

decarbonator-820The Heil Series 820 Decarbonator is specifically designed to efficiently desorb or remove contaminants such as CO2, VOCs, H2S, etc. from the incoming liquid stream coming from water treatment,  process streams, landfill remediation, etc..

Although desorption (stripping) is the functional opposite of absorption (scrubbing), the same essential type of equipment is used.  The contaminated water is introduced at the top of a packed column, while fresh air, void of any contamination, is introduced at the bottom of the column.  Traveling a torturous route through the packing extends the contact time between the air and the liquid, as well as, increasing the intimacy of gas/liquid contact.  As the air and water move through the column countercurrently to one another, the contaminant diffuses from the water to the air.  The water leaving the bottom of the column is cleansed of contaminants. 

The type of contaminant in the liquid stream, along with the desired removal efficiency will determine the bed depth, packing size, fresh air rate and chemical requirement, if necessary.

Prior to leaving the scrubber, the contaminant air passes through a mist eliminator (Heilex EB 4-Bend Mist Eliminator Blades or mesh pad) to remove entrained droplets.

Series 820 Applications

Heil Series 820 Decarbonator are ideally suited for service in a wide variety of applications in industries such as chemical, mining and water treatment.    In addition, the Series 820 Decarbonator has been used successfully for the control of CO2 in water treatment projects.

Series 820 Features

Principal features of the Series 810 Degasifiers are:

Principal features of the Series 820 Decarbonator are:

High Efficiency – Proper sizing of the unit, selection of packing and packing depth, irrigation rate and chemical feed can result in efficiencies of 99% or better.  Standard units contain 10, 15 to 20 ft of packing.  Units are custom designed to the specific requirements of each individual application.

Low Initial Cost – Pre-engineered standard designs are available from 16 gpm to 2,250 gpm.

Low Operating Cost – Pressure drops through the decarbonator at conventional gas/liquid ratios used for stripping are 0.15” wc/ft of packing depth or less.

Versatile – The Series 820 Decarbonator is designed to handle a wide variety of applications from decarbonating a water treatment stream, stripping VOCs, or degasifying a contaminated liquid.  Units can be staged in series to achieve maximum efficiencies even on the most difficult applications.

Extended service life – The Series 820 Decarbonator has been designed with maximum corrosion resistance as a primary consideration.  The wide selection of corrosion resistant materials feature Rigidon FRP (Fiber Reinforced Polymer) as a standard material with thermoplastic, dual laminate (thermoplastic with FRP overlay), stainless steel and other alloy construction available.

Series 820 Equipment Selection 

The key factor in selecting the right countercurrent scrubber for a given application are liquid rates to be decontaminated, type of contaminate(s) present, quantity of contaminant present and the required removal efficiency.

Heil’s engineers will gladly assist in the selection of a decarbonator, as well as sizing and selection of accessory items, such as feed pumps, fans, chemical feed systems, etc. to make a complete decarbonator system.

Heil’s engineers will then provide a specific quotation on the appropriate decarbonator.
