Are you familiar with carbonation? Perhaps not all of you know this word and yet you see the results of carbonation almost every day; it provides the bubbles in your cola or mineral water :) In this process flow meters play an important role. The flow meter measures and controls the amount of carbon dioxide (CO2) to be dissolved in the carbonated drinks during the carbonation process.
Guillaume WURGER, company manager of Actemium Strasbourg Plant Solutions, explained me all about their carbonator as this is one of their flagship activities and how they use flow meters in the process.
Carbonation is a chemical process, the saturation of a liquid with carbon dioxide. This thermodynamic phenomenon can be explained by Henry's law. This essential law of physics stipulates that at a constant temperature, the quantity of gas dissolved in a liquid is proportional to the pressure exerted by this gas on the liquid.
In case of carbonation, the goal is to obtain a certain concentration of CO2 in a liquid. It is essential to consider the specific pressure and temperature conditions which must be respected, depending on the type of product. This balance must be perfectly controlled throughout the process and this is the point where flow instruments come into the picture.
Actemium Strasbourg Plant Solutions is a VINCI Energies company and specialises in process solutions, like mixing skids, gas injection systems and pasteurisation. Carbonation is one their core activities.
“Ten years ago, our taste for innovation led us to develop a carbonator which we patented and which enables our customers to produce carbonated drinks. We have taken up the user's problem with traditional solutions: CO2 injection efficiency, a bulky system and energy-consuming process. With this equipment, the challenge is to:
The dissolution of the CO2 in mineral water - or other soft drinks – ensures the carbonic acid to appear, which gives the beverage a ‘fizz’. The pressure and temperature conditions in the process are essential to regulate the amount of gas to be dissolved.
In our case, we work in line with high pressure conditions for a controlled period of time, which guarantees that 100% of the injected gas is dissolved. A perfect yield, as we only inject the quantity of gas we need! To precisely control the CO2 gas injection, we use Bronkhorst GAS mass flow controllers, from the IN-FLOW High-FLOW range.
To solve the problem of the inconvenient and consuming CO2 tanks you need a solution capable to inject gas in-line and continuously. But without a tank, you have no buffer volume available: which means your gas injection system must be able to deal with variations in the liquid flow line, changes in flow rates and start/stop functions. These are challenges you must face in a continuous process like this!
To achieve this, we created a recirculation loop in our system. The flow will be controlled by the system's internal pump and the recirculation depends on the needs of the downstream bottling machine. This way we do not use a tank, so we can get as close as possible to the bottling machine. The Bronkhorst IN-FLOW High FLOW mass flow controllers are ideally suited for this application. Their technology based on a thermal principle makes them insensitive to pressure variations and they regulate the flow rate with the help of the instrument's internal PID loop. The low response time also allows them to compensate for process variations, without impacting on the accuracy of the amount of CO2 added into the beverage.
In the traditional system, the flow sensor, control loop in the PLC and control valve were all separately installed. The Bronkhorst solutions provides us a 3-in-1 solution with a very low reaction time, a higher control resolution than the PLCs on the market and with a compact electric actuator. Besides that, the flow instruments are equipped with industrial communication protocols that allow access to the control parameters of the devices.
Actemium uses the Profinet network, which has improved the speed of transmission, the accuracy of the signals and the fact that it is possible to monitor the parameters present in the instrument. With these features, Actemium ensures that it supplies quality equipment to its customers and meets their needs.
