Pulp and Paper Industry Applications for Level Measurement
Posted on December 2, 2014 by magnetrol
Increasing competitive, regulatory, supply chain and customer demands have driven the need for process improvement in the pulp and paper industry. In our three-week blog series, Magnetrol® reviews the critical impact that level control makes in improving process efficiencies and safety for pulp and paper mills. This week, turpentine and liquor recovery processes are explored. Next week, we cover plant-wide operations including MC pump standpipes, water storage, chemicals and additives, and lubrication and hydraulic oils. You can also read our first blog article about the pulp and paper industry, which features level measurement applications from chipping to papermaking processes.
Application: Vapors from the digester contain turpentine and 85% of it is released during the relief cycle. Recovery of this volatile organic compound (VOC) is undertaken for environmental reasons, to lessen effluent treatment of condensate, to utilize turpentine as a fuel source, or to sell it as a by-product to chemical processors.
Challenges: Two vessels in a typical recovery system require level control of the turpentine/water interface: the decanter, or separator, and the storage tank. The National Fire Protection Association (NFPA) rates turpentine as a “severe fire hazard.” For this reason, the decanter is contained in a dyked area, storage tanks are sometimes located below ground, and controls must be rated explosion-proof.

– Eclipse® Guided Wave Radar Transmitter or Pulsar® Non-Contact Radar for continuous level
– Atlas® Magnetic Level Indicator for visual indication
BLACK, GREEN AND WHITE LIQUOR RECOVERY
Application: Black liquor is the digester waste mixture of spent chemicals and lignin extracted from wood chips. When burned in a recovery boiler, black liquor produces heat for steam and also releases digester chemicals called “smelt.” Mixed with water, smelt becomes green liquor. This is treated with lime in the causticizers to produce white liquor, the digester’s cooking chemical.
Challenges: Stored in varying concentrations, liquors are corrosive solutions with high levels of organic compounds. Liquors can cause chemical burns or damage the lungs if inhaled. Level sensors contend with the chemicals’ harshness, variable density and dielectric, agitation, foaming, and media stickiness. Tank controls should activate the appropriate alarms or emergency shutdown systems.

GE Predictivity™ Solutions Join ecomagination Portfolio
It has been three years since Marc Andreessen, co-founder of the venture capital firm Andreessen Horowitz, wrote his influential essay, Why Software Is Eating the World. Since that time, the impact of software in industrial applications has grown substantially. GE’s Industrial Internet is playing an important role in advancing the use of software in this arena. However, in addition to eating the world, it has now become clear that software can play an important role in helping to save the world from growing resource scarcity.
The fact is, a great global resource challenge is now upon us. The demand for natural resources is outstripping available supplies in many regions around the world. Regional resource imbalances are occurring for energy, water, food, and materials. These imbalances are driving up commodity prices and creating resource stresses that have social, political, and economic implications.
This challenge is poised to become even greater in the years ahead. Expected increases in gross domestic product (GDP) and population levels over the next 15 years will translate into even stronger levels of resource demand. Our analysis indicates that in the absence of additional improvements in the intensity of resource use per dollar of GDP, both materials extraction and energy consumption will increase by 80% by 2030.
Ecomagination is GE’s commitment to developing technologies that reduce our consumption of natural resources, while creating economic benefit for our customers. Established in 2005, GE’s ecomagination program has been at the forefront of resource productivity solutions for a decade. Now, with the addition of the Predictivity solutions to the ecomagination portfolio, GE has an even greater potential to play a key role in responding to the global resource challenge.
The integration of efficient hardware with Internet-enabled software is the new frontier of natural resource productivity. This approach provides an avenue to achieve resource productivity improvements above and beyond those that can be achieved through hardware advances alone. In a recently published white paper on this topic, we call this Digital Resource Productivity, and we believe that productivity improvements can be doubled over the next 15 years by integrating software and hardware to optimize resource use.
It would appear our customers agree. In a recent survey conducted jointly by GE and Accenture and captured in the Industrial Internet Insights Report for 2015, the ability to “improve environmental safety and emissions” was chosen as one of the top three priorities for the use of big data analytics in the next 1-3 years.
Some examples of how the powerful combination of big machines and big data can have real world positive influences include:
Power FlexEfficiency: Uses data sensors and data science to produce up to 10% greater turbine power output
Wind PowerUp: Produces up to 5% additional power for wind farms
Flight Efficiency Services: Results in reductions of up to 1,600 lbs CO2 emission per flight and gains of up to 2% fuel efficiency using flight and operational data
Trip Optimizer: Produces up to 10% emissions reduction and up to 10% energy savings with a sophisticated optimization solution for rail
Water & Process Technologies InSight™: Enables industrial companies to reuse municipal wastewater instead of fresh water to meet the demand for cooling
At GE, we are excited about the opportunity to play a role in helping to confront the global resource challenge. Today we are embarking upon a new frontier of digital resource productivity by expanding ecomagination to encompass GE’s Predictivity suite of solutions. Join us as we help transform the future of global resource productivity.

Improving Solar Power Efficiency Through Level and Flow Control
SEPTEMBER 2, 2014 / MAGNETROL
Solar technologies use the sun’s energy to provide electricity, hot water, process heat and cooling. According to the U.S. Energy Information Administration, solar power presently provides less than 1% of U.S. energy needs, but this is expected to increase with the development of more efficient solar technologies. One way to enhance solar power efficiency is through the use of level and flow instrumentation to drive process improvement.
TYPES OF SOLAR COLLECTORS
Different solar collectors meet different energy needs. Passive solar designs capture the sun’s heat to provide space heating and light. Photovoltaic cells convert sunlight directly to electricity. Concentrating solar power systems focus sunlight with mirrors to create a high-intensity heat source, which then produces steam or mechanical power to run a generator that creates electricity. Flat-plate collectors absorb the sun’s heat directly into water or other fluids to provide hot water or space heating.
SOLAR LEVEL AND FLOW APPLICATIONS
Heat Transfer Fluid Storage: Large-scale solar collectors for electric power generation require a heat transfer fluid (water, thermal oils, or ionic liquids) to absorb the sun’s heat for generating steam. Arrays of mirrored panels convert the sun’s energy into +750° F (+399° C) thermal energy that’s hot enough to create steam for turbines. The mirrors focus sunlight onto pipes of heat transfer fluid that run along the mirror’s centerline. The fluid then boils water to produce steam. Thermal fluids also help provide hot water and heat. Thermal fluids are typically stored in pressurized tanks that require level monitoring.
Recommended Continuous Level Technologies: Displacer Controller, Guided Wave Radar
Recommended Point Level Technologies: External Cage Float
Hot Water Storage: High-temperature solar water heaters provide energy-efficient hot water and heat for large industrial facilities. Thermal storage in buffer tanks provides interfaces between collector subsystems and energy-using systems. The preferred solar storage vessel is a vertical cylindrical tank designed for the maximum pressure of the supply water source, which may be as high as 150 psi.
Recommended Continuous Level Technologies: Displacer Controller
, Guided Wave Radar
Recommended Point Level Technologies: External Cage Float
Pump Protection: Flow switches protect pumps from damage due to leaks or if a valve is accidentally closed downstream. A flow switch will actuate an alarm and shut down the pump when flow drops below the minimum rate.
Flow Alarm: Thermal Dispersion Flow Switch for High/Low Alarm, or Flow Switch
LEVEL AND FLOW INSTRUMENTATION FOR SOLAR POWER EFFICIENCY

Increasingly, industrial process operators are recognizing the advantages of the direct measurement of mass flow rate for monitoring gases. The following article discusses the difference between volumetric flow and mass flow measurement for gas control applications, and is excerpted from the Magnetrol® Thermal Dispersion Mass Flow Measurement Handbook.
An Introduction to and Benefits of Thermal Dispersion Mass Flow Measurement
Accurate mass flow measurement of gas is difficult to obtain. The main reason is that gas is a compressible fluid. This means that the volume of a fixed mass of gas depends upon the pressure and temperature it is subject to
Consider a balloon containing one actual cubic foot of gas at room temperature (70° F) and atmospheric pressure. An increase in the room temperature causes the balloon to expand. An increase in the pressure surrounding the balloon results in a decrease in volume. Although the volume of the balloon changes with variations in pressure and temperature, the mass of the gas inside the balloon has remained the same. This illustrates how pressure and temperature affect the actual volume
There are many well-established methods of measuring the actual volumetric flow rate. However, the measured flow rate will vary with changes in temperature and pressure. For virtually all industrial process operations, the user wants to measure the mass flow rate instead of the actual flow rate. Chemical reactions work on the basis of mass relationships of ingredients. Combustion is based upon the mass flow rate of the air and the fuel. Gas consumption in a facility is based upon mass flow rate. To accurately measure mass flow, the actual flow rate must be adjusted to correct for any change in temperature and pressure.
Thermal mass flow technology is a method of gas flow measurement that does not require correction for changes in process temperature or pressure. Thermal mass flow technology also has a benefit of measurement at low velocities and greater turndown capabilities than those obtainable with other flow measurement devices. Turndown is the flow range for which the device is accurate (maximum flow / minimum flow).
What is Mass Flow Rate?
Mass Flow is the measurement of the flow rate without consideration of the process conditions. Mass flow is equivalent to the actual flow rate multiplied by the density. M = Q x ρ, where Q is the actual flow and ρ is the density. As the pressure and temperature change, the volume and density change, however the mass remains the same.
To obtain standardization of gas flow measurement, Standard conditions of Temperature and Pressure (STP conditions) are utilized. Gas flow measured at STP conditions is corrected from the actual process conditions to standard conditions (more information about standard versus actual process conditions can be found in our Thermal Dispersion Mass Flow Measurement Handbook).
The simplest way of measuring mass flow of gas is in units of cubic feet per minute or cubic meters per hour, corrected to STP conditions. This is referred to as SCFM (standard cubic feet per minute) or the metric equivalent of Nm3/h (normal cubic meters per hour). The density of a gas at standard conditions is known, thus providing a relationship between SCFM and pounds per hour or between Nm3/h and kg/h.
The conversion between the volume at actual conditions and the volume at standard conditions is based on the ideal gas law — actual volume increases in direct proportion to an increase in absolute temperature, and decreases in direct portion to an increase in absolute pressure. Consider the balloon example — as the temperature increases, the volume expands; as the pressure increases, the volume shrinks.
Absolute pressure of zero psia (pounds per square inch at absolute conditions) is a perfect vacuum. One atmosphere of pressure is defined as 14.69 psia or zero psig. The conversion between psia and psig is easy: PSIA = PSIG + 14.69. If you have a pressure gauge calibrated for psig, it will read zero at sea level and only measure gauge pressure above atmospheric pressure. The following chart will help clarify this.
Absolute zero is defined as the temperature where molecular motion stops. It is defined as 0 K (Kelvin) which is -273.16° C or 0° R (Rankine) which is -459.67° F. To convert between actual temperature and absolute temperature, simply add 460 to the temperature in degrees Fahrenheit or 273 to the temperature in Celsius.
Once we establish a set of conditions as a standard temperature and pressure (STP conditions), we can convert between the flow rate at actual conditions and the flow rate at standard conditions.
The subscript (a) refers to actual conditions; the subscript (s) refers to standard conditions.
Unfortunately, not all STP conditions are universal. Many users consider one atmosphere and 70° F as STP. Some industries use one atmosphere and 60° F as standard; others use one atmosphere and 32° F as standard. The metric equivalent is Normal conditions which are based on a pressure of one bar (14.5 psia) and 0° C.
The important issue is that Standard Conditions are not Standard and a mass flow meter needs to be able to permit the user to select the desired STP condition. An error of approximately 8% will occur if there is a difference in STP conditions between 70° F and 32° F.
Once a set of standard conditions is identified, the density of that gas at these conditions is known. Therefore, it is a simple matter to convert from SCFM to mass in pounds per hour:
In this formula, the density in pounds per cubic foot is the density at the specified STP conditions.

Foam Measurement and Liquid Level Instrumentation: A Magnetrol Applications Study
Process media susceptible to foaming are particularly challenging to accurate liquid level measurement. Foam’s lower density, as compared to a foam-free liquid, will absorb or deflect a substantial portion of the return signal, diminishing the all-important reflectivity required by non-contact measurement technologies. Depending on the degree of foaming, a foamed medium can also turn aggressively sticky and completely lose all flowability.
A Magnetrol® prepared foods customer in Europe is well aware of the high demands that foam measurement places on liquid level instrumentation technology. The company’s chocolate mousse product is intentionally infused with air to give it the light and airy texture that is the signature of this dessert. The very name “mousse” is the French word for “foam.”
The mousse filling system, with its multiple storage containers, measures chocolate mousse levels at various stages of foaming. Each of these stages varies greatly as the system controls the dosing, foaming and other processes. A total of five measurements are required to produce the liquid, with several additional steps to create the ready-made mousse.
But a continuous, reliable and repeatable measurement for the application had evaded the food processor. Competitive solutions faltered, including guided wave and through-air radar devices, as strong buildup took down capacitance and the lack of fluidity eliminated float technology. It always came down to signal loss, measurement errors and massive production waste, either by over- or underfilling the reservoirs.
Finally, the MAGNETROL Eclipse® guided wave radar transmitter with a hygienic single rod probe gave the customer a solution to this tricky measurement application. With just a single sensitivity adjustment to the transmitter, the entire measuring range produced results that eliminated any need for high- and low-level switches. Even the built-in tank agitator did not challenge the performance of the ECLIPSE device. After the customer screened the measuring capability of the ECLIPSE model within an experimental facility, the plant manager gave the thumbs-up to install the transmitter in all five tanks.
At another prepared foods facility in Europe, it was the level (with foam) measurement of a yogurt filling system that was causing headaches. This company requires a continuous, reliable and repeatable level measurement in the filling system for its low-fat yogurt. Feeding the filling machine on the production line are three different tanks, each one requiring its own level sensor.
Derived from the Turkish word for “curdled,” yogurt is a thickened dairy product produced by bacterial fermentation of milk. Making the yogurt product creates significant foaming in the feed tanks, an issue that a level instrumentation competitor said could be solved using capacitance and guided wave radar devices in tandem. But when these devices were applied, measurements failed by indicating either zero level or 100% level.
When Magnetrol proposed an ECLIPSE guided wave radar transmitter, a comparison test was requested. The two feed tanks were equipped with ECLIPSE units and the third tank was equipped with a competitor’s capacitance sensor. Because ECLIPSE was manufactured with the competitor’s standard process connection—a SMS nut—it was very easy to change between the two different level devices.
During the six-hour test, the two installed ECLIPSE units worked without a single failure. During the clean-in-place cycle and the product changeover, the ECLIPSE models again performed flawlessly. The customer replaced the competitor’s capacitance sensor on the third tank with one more ECLIPSE transmitter. Today, all the yogurt tanks at the facility are functioning at optimal levels, using ECLIPSE guided wave radar technology.
