Liquid CO2 Evaporator
an energy saving solution
Traditionally liquid CO2 is evaporated using either Steam or Natural air or Forced air draft or cooling tower water. Undoubtedly, energy is being lost in these conventional systems. However, this way of evaporating CO2 has begun to change ever since Hypro introduced energy-saving & energy recovery CO2 evaporators in the year 2000. Several Breweries have benefitted from the system installed by “Hypro” and are reaping benefits.

Product Description
02
Functionality
When sufficient liquid CO2 accumulates in the storage tank, it is passed on to the CO2 evaporator depending upon the demand for CO2 in the process plant. Ambient air is supplied to the evaporator for heating the liquid CO2. The vapor CO2 is then supplied to the process plant. Buffer Tank ensures constant pressure of CO2 gas to the Brewery. If the airflow is less than required or vapor CO2 outlet flow is greater than designed for, the safety interlock will close the actuated valve fitted on the buffer tank outlet. This will stop liquid CO2 flow from the storage tank to the evaporator. This is the safety to avoid Liquid CO2 carry-over.

Frequently Asked Questions.
As CO2 cannot exist in a liquid state at atmospheric pressure, CO2 is maintained at a reasonable and constant temperature between -57 dec C to + 31 deg C and pressure of 5.2 bar in the CO2 Cylinders.
Liquefied carbon dioxide has many applications, particularly useful in the beverage industry for carbonating beverages, such as beer and soft drinks.
Hypro provides an improved system and a process for carbon dioxide liquefaction/condensation and CO2 evaporation wherein energy is recovered to maintain the cooling media at a lower temperature.
Power required for CO2 compressors is about 0.045 kwh/kg of CO2 condensed using Hypro System. For conventional schemes, the same is about 0.08 kw. This results in about 40 % power savings as compared to a conventional CO2 liquefaction plant.
