Accurate dosing of corrosion inhibitors

Cori-Flow

In industrial applications, especially in the chemical, process and oil and gas industry, corrosion can be a real challenge. These types of industries are coping with demanding environmental and process conditions in production and operation. Prevention or control of corrosion by inhibiting often proves to be an economic solution.

A corrosion inhibitor system will add small concentrations of (bio)chemicals into the process. The effectiveness of an inhibitor system greatly depends on the correct injection amount, and can be influenced by the environmental and process conditions; so accuracy is crucial here.

Using a low flow control system containing a Bronkhorst (mini) CORI-FLOW mass flow meter can help you dose amounts of corrosion inhibitors more accurately. High accuracy and high turndown ratio is achieved based on pure mass flow measurement with this flow meter. It can directly control valves and pumps by on-board PID control and can be further optimised with PLC and HMI control extending both performance and flexibility.

Bronkhorst’s Coriolis dosing system approach enables real-time monitoring, control and logging of injection rates. This allows online checking of flow rates and instantaneous re-setting of the required flow rate. Asset management and preventive maintenance is supported with several active diagnostics.

Flow meters and controllers in the food industry

In the food industry there are many applications in which gases or liquids need to be measured or controlled. For example, these applications include the aeration process or the dosage of additives, like flavors and colourants. Indirectly, surface treatment applications like the sterilization of packaging is of high importance as well. Bronkhorst has published many stories regarding the omnifarious and demanding food industry and I would like to share some of these stories with you.

There is a huge variation in candy available on the market, each brand with its own taste, texture and appearance. Erwin Broekman had the opportunity to visit Haas-Mondomix, a machine builder that is specialized in equipment for the food industry. With ultrasonic volume flow meters, Haas-Mondomix measures the amount of additives – flavourings, colourings and acids – that are added to the main stream of the production process.

In the chocolate confectionery industry, there’s an ever increasing number of variations in flavours as well. Due to this enormous growth, mass flow meters and controllers find their way into the confectionery industry. Coriolis flow meters in combination with a pump are an ideal solution for dosing flavors and functional ingredients. Read more about dosing flavor into chocolate.

Aeration within the production process of delicacies like ice cream and cake

Ice cream is made by freezing and simultaneously blending air into a brewage of fat, sugar and milk solids. Air makes up anywhere from 30% to 50% of the total volume of ice cream, so aeration is crucial during production. A side effect of adding air to ice cream is that it tends to melt more quickly. Thus, for attaining an optimal structure of the ice cream, it’s important to have a stable inlet air flow in the production process with a constant cream/air ratio. This can be achieved by using a mass flow controller.

Aeration is also a crucial process in the production of whipped cream. This is done at Hansa Industrie-Mixer, a worldwide company that operates in the field of mixing machines and foam generators for the food and non-food industry. Hans-Georg Frenzel, technical director at this company, explains how mass flow controllers are important in the production of cake in his blog.

Steralisation of food packaging to reduce food waste

However, all that food production does have a downside; food waste. Globally food is lost or wasted at different points in the supply chain. One of the ways to reduce food waste is to improve the sterilization of the packaging that food is placed in, to reduce spoilage and increase shelf life. This is the point where Controlled Evaporation Mixing (CEM) systems come in the picture. James Walton explains Bronkhorst’s share in the extension of the shelf life.

FLUIDAT-database-780x340

Bronkhorst High-Tech BV, the Netherlands, has expanded its database of gas and liquid properties with 1000 fluids to over 1800 fluids. This comprehensive database, called FLUIDAT®, is used by the company for configuration and extremely accurate calibration of its extensive portfolio of flow meters and controllers, and for calculating pressure differences, valve seats, etc.. The most complete, most accurate database in its kind is also available as a free, online calculation tool for Bronkhorst customers who, for example, want to determine conversion factors when they want to use their flow meter for a gas (or gas mixture) other than that for which the instrument is calibrated. This online calculation tool, Fluidat on the Net (www.fluidat.com), is also very valuable for physicists who need to calculate fluid properties or need to consult the vapour pressure curve.

EL-FLOW® Prestige, Bronkhorst’s high-performance gas mass flow meters and controllers, are standard equipped with the data of 100 unique gases from the FLUIDAT database, offering the user unsurpassed flexibility in varying gas type with optimum accuracy. With the embedded gas data, the EL-FLOW Prestige calculates real-time the gas conversion based on the actual gas properties. The free and easy-to-use software tool FlowTune® enables the user to change the instrument’s configuration swiftly via his computer.

Bronkhorst CEM Systems for NASA Research

From BronkhorstUSA.com:

The National Aeronautics and Space Administration (NASA) recently redesigned the system used to test the new space suit Portable Life Support System (PLSS) that is under development. In order to test the PLSS a simulated human metabolic load must be applied to the various sub-systems and so NASA needed to simulate the human production of CO2 and water vapor with its associated heat load.

Working closely with NASA engineers to fully understand the application requirements, Bronkhorst learned that accurate, stable control of water vapor was critical to efficient and repeatable testing and therefore successful development of the PLSS.

The recommended Bronkhorst solution was a CEM system to properly control the mass of water being vaporized as well as the amount of CO2 in the vapor. NASA has three CEM systems connected to an outlet manifold. Each CEM system consists of a liquid mass flow controller (H2O), a gas mass flow controller (CO2), a Controlled Evaporator Mixer, and a readout/control unit. The three connected CEM systems are collectively referred to as the Human Metabolic Simulator (HMS).

The Bronkhorst HMS equipment is controlled via analog (0-5 Vdc) signals through the Bronkhorst readout/control units (1 per CEM system) which in turn are connected to the NASA main test system running NASA’s customized LabVIEW software.

This setup allows NASA to simulate those aspects of human metabolic output up to a rate of ~3500 BTU/hr, or a bit over 1000 Watts, by injecting the CO2/water vapor mix into a simulated spacesuit volume containing a manikin (“Manny”) which is wearing a Liquid Cooling and Ventilation Garment (LCVG). The LCVG removes sensible heat to keep the human core temp in nominal range, and also provides some latent heat removal via condensation of human-generated water vapor on the surface of the cooling tubes.

To complete the human metabolic load simulation, NASA has placed controllable heaters on the CO2/H2O vapor deliver lines to prevent condensation and to add super-heat as needed. Additionally, they have controllable electric heaters on the manikin body to simulate sensible heat generation by a human being working at various levels of effort. There is also a Bronkhorst Mass Flow Controller to remove gas from the suit at rates that simulate metabolic consumption of suit gas as well as suit leakage.
