Thermal Flowmeters for Wastewater Applications

Kurz Flowmeter for Wastewater Applications

Wastewater treatment plants ( WWTPs) or publicly owned treatment plants (POTWs) must operate 24/7 to satisfy domestic, industrial, and storm drain sources. Sewage treatment includes eliminating pollutants from wastewater and sewage (human waste, animal waste, soaps, and detergents) to create a safe fluid waste stream that can be reintroduced safely into the ecosystem and a solid waste appropriate for reuse (usually as fertilizer). The primary applications for flow meters in wastewater treatment settings measure blower air to each pool in the aeration basin and measure digester gas flow.

Kurz Flowmeter on Digester
The aeration basin is an array of treatment pools containing aerobic bacteria that break down the pools' sewage. A blower adds the necessary dissolved oxygen (DO) to the aerobic bacteria in the aeration basin. Too little oxygen destroys the bacteria, and too much oxygen is expensive; running the aeration blower accounts for up to 60% of all wastewater power consumed.

Digester sewage is called "sludge." When bacteria is added to the digester, the sludge breaks down and releases gas. This digester gas is collected, compressed, it's excess moisture gets removed, and is then cleaned in a scrubber. The cleaned gas is sent to engines or fuel cells for power generation, boiler water heating (for steam or hot water), and excess gas burns off at the flare. Many extensive sewage treatment facilities use digester biogas to operate the plant, minimizing their grid power consumption.

Developing accurate flow rate data allows wastewater treatment facilities to more precisely manage digester production levels, enabling tighter controls on methane levels and flaring. Kurz Instruments provides a handy overview of where thermal flowmeters are applied and provide optimal performance.

Thermal Flow Meters for Pulp & Paper Applications

Thermal Flow Meters for Pulp & Paper Applications
Trees used in paper-making go through processing in a de-barker and a chipper, where they reduce to approximately one-inch wood chips. The wood chips are pressure cooked in a digester and become pulp, refined, turned into slush, and screened. Screening drains away liquid, and the resulting pulp is then pressed and dried into the paper. Several steps within the pulp and paper-making process create emissions that must be monitored and reported.

Creating paper pulp relies on a careful balance of low-velocity air flows among the various processes. For example, the recovery boiler following the digester modulates to follow the digester load changes. Additionally, a recovery boiler uses the black liquor's chemical reaction to generate heat for the boiler. It has three airflow systems requiring tight control to create stable air flows.

Kurz Instruments provides a good application note explaining the areas where thermal flow meter uses appear in the pulp and paper production process. You can download the application note below.

Ball Valves Used for Black Liquor in Pulping Kraft Process

Black liquor valves

Many toxic, corrosive, and reactive chemicals are used in pulp and paper mills in chemical pulping. This incredibly hostile environment requires well-engineered automatic valve systems and durable valve actuators, spring units, and positioners. 

Suppose you understand how paper is made and what chemicals are usually used in the atmosphere. In that case, you can instantly understand why special consideration is required for valve and actuator selection.

In the early stage of paper production, digesters combine high heat and a heavy alkaline liquid called "white liquor" to convert wood chips into a pulp during separation from wood chips. White liquor (mainly sodium hydroxide and sodium sulfide), process water, heat, and pressure are used to separate wood chips into lignin and cellulose fibers. The white liquor breaks down the lignin (the substance that binds the wood fiber together) in wood chips. The resulting combination of water and spent white liquor produces "black liquor." This liquid pulp residue mixture made up of lignin and hemicellulose, and inorganic compounds such as sodium hydroxide and sodium sulfide is toxic. Another by-product of this process is Hydrogen Sulfide, a toxic, corrosive, and flammable gas. 

Effects on Ball Valves

In piping and ball valves, managing these process chemicals and by-products is difficult. Pipe diameters range from 2"-10", but the most common sizes are 4", 6" and 8." Usually, these processes are ANSI / ASME Class 150 and ANSI / ASME Class 300, the most common end connection being 150 # and 300 #. Process temperatures are usually high, between 250 ° F and 350 ° F. The valve body and end connection materials are generally 316 stainless steel, but you'll also find carbon steel requested. Applications can include manual lever, gear operators, pneumatic actuators, and electrical actuators in valve assemblies.

The most concerning issue is the sticky molasses-like liquor builds upon the ball valve face and contaminates the back seat spaces, inducing strong internal clearance forces, resulting in valve lock-up over long static periods. A superior ball valve seat design from A-T Controls addresses the viscous material problem.  

A-T Controls developed a solution for this extreme pulp and paper service and black liquor service with notable improvements to their FMS series. This valve incorporates a "scraper seat" feature that eliminates the molasses-like residue baked on the ball's face and eliminates valve lock-up. The addition of Aflas ® o-rings seal the seat cavity from media build-up, and a Venturi hole in the ball is also provided.

Typical black liquor ball valve from A-T Controls:

  • Series: A-T Controls FMS
  • Sizes: ½" -8"
  • Rating: ANSI/ASME Class 150/Class 300 with 150# and 300# flanges, API 607.
  • Ball and Seats: Tungsten Carbide coated metal scraper seats (Aflas® o-rings and Venturi Ball for black liquor service.) 

Please consult a Piping Specialties Applications Engineer for material selection for your black liquor application. This information is a guideline, and customers are solely responsible for construction materials, preparation of the valves for service, and lubricants being compatible with their black liquor application.

Refractometer Application in Kraft (Sulphate) Pulp Process: Digester Washing Zone and Blowline

Refractometer Black Liquor

Introduction

The first operation in the Kraft pulping process involves the extraction of cellulose from wood by dissolving the lignin that binds the fibers together. This is done in a strongly alkaline solution.

This process is known as cooking. After the wood pulp is obtained, it is washed and bleached to obtain the fibrous product.

To optimize the pulp chemical consumption and water usage, the black liquor concentrations have to be measured before and after washing.

Application

Incoming wood is debarked and chipped to an optimal size to minimize fibre damage, and to maximize the impregnation with the cooking liquor. The chips and the cooking liquor are fed into a large vessel known as digester. The pulping reaction takes place under pressure and at a high temperature.

After cooking, the pulp passes through a blow line to the blow tank and then to a washing section. The diffuser washers separate the black liquor from the fibers by washing them with a washing liquor or water. The products from the fiber line are a clean pulp, and a diluted black liquor known as weak liquor.

The washed pulp is then screened before it is sent to the bleaching plant, and the weak black liquor passes from the washing section to the chemical recovery process.

Instrumentation and installation

The K-Patents SAFE-DRIVE Refractometer PR-23-SD measures in real-time the Total Dissolved Solids (TDS) content in black liquor.

K-Patents PR-23-SD
The K-Patents refractometer is installed in-line in different points after the digester. TDS measurement
in the blow pulp suspension after the digester enables monitoring of the diffuser operation. Together with other measurements (e.g. filtrate and flush liquor) this provides the mill with the ability to control the performance of the washing zone in the digester. In addition, TDS measurement in the blow line allows the performance of the digester to be monitored, ensuring that it yields the correct concentration. The combination of these measurements facilitates continuous calculation of the mass balances of the digester.

The refractometer’s measurement is unaffected by bubbles, particles, consistency, flow, ion changes, pH, temperature, pressure, color or turbulent flow. The measurement surface is periodically cleaned using an integrated and automatic prism cleaning system.

The K-Patents PR-23-SD 

Black liquor concentration measurement with the SAFE-DRIVE process refractometer helps to increase washing efficiency, obtain a consistent pulp quality, reduce bleaching chemical consumption and environmental load, and increase evaporation efficiency.

An Innovative and Unique Solution for Measuring Dry Gas Flow in Wet Gas Environments

Kurz Wet Flow

The Problem - Reading Dry Gas Flow in a Wet Gas Environment


Irrespective of any single manufacturer's claim, daily and seasonal temperature changes in wet gas environments cause erratic high flow readings in standard thermal flow meters. With standard thermal flow meters, as the flow flow temperature decreases, more water condenses out of the gas causing the standard thermal flow meter to misread the water contacting the sensor as dense air. Within an active condensing gas flow, the low overheat (less than 50°C) of standard flow meter products make them incapable of accurately reading the dry gas flow within a wet gas environment.

Kurz Instruments Develops a Practical Implementation of the Leidenfrost Effect to Overcome the Problem


Leidenfrost Effect
The Leidenfrost Effect, named after 18th Century scientist Johann Gottlob Leidenfrost, is a phenomena that happens when liquid contacts a surface significantly hotter than the liquid’s boiling point.  A vapor layer is created between the liquid and the surface that keeps the liquid suspended, delaying the rate of evaporation. 

Kurz Instrument developed an innovative solution. By maintaining a high signal-to-noise ratio and a high sensor overheat, mist particles vaporize on impact with the heated sensor. Thus, by employing the Leidenfrost Effect, the leading edge of larger droplets vaporize to steam, which diverts the remaining water around and away from the heated sensor. The unique design of the WGF allows it to accurately monitor the dry gas component in a wet gas flow regardless of changing condensation levels.

The Kurz WGF flow meter for condensing gas environments includes features that allow them to outperform all other currently available thermal mass flow meters. Kurz was the first thermal mass flow meter manufacturer offering accurate and reliable condensing gas flow measurements. Their unique design centers around a high 300°C sensor overheat capability. The design also provides sensor overheat protection at zero flow through the incorporation of a unique temperature control and power limiting design. As a result, the Kurz WGF is not affected by water droplets in the flow stream. This unique technology establishes Kurz flow meters with WGF technology as the only thermal flow devices suitable for biogas and condensing gas environments found in digesters, landfills, animal feeding operations, mining, and wet stacks.

Process Refractometers Improve Production and Quality of Phosphoric Acid Production

Phosphoric Acid Production
Phosphoric acid is an important product used in industrial applications such as the manufacture of agricultural phosphate fertilizers, detergents, pesticides, metal coating, etc. Due to its non-toxic and mildly acidic nature, phosphoric acid is also used in other applications including food flavoring, soft drinks, pharmaceuticals, dental products, cosmetics, and skin care products.

Phosphoric acid is produced by mining the naturally occurring phosphate rock and processing it via a wet process or a thermal process. The concentration of the acids during the wet process can be measured inline with the process refractometers, such as those manufactured by K-Patents.

To learn more about where and how these refractometers are used in wet process phosphoric acid production, visit the PSI Controls web page.

Process Control Case Study: Refinery Explosion and Fire


A case study of the 2018 Husky Energy refinery explosion in Superior, WI. This animated video recaps all the events and circumstances leading up to an explosion starting in the Fluid Catalyst Cracker (FCC). The key factor was an eroded sliding gate valve that allowed a protective layer of reactor catalyst to disappear. This allowed air and hydrocarbon to blend, forming a combustible mixture, and setting the stage for a chain reaction of events. This video, courtesy of the Chemical Safety Board (csv.gov) is an excellent educational reference and should be viewed by engineering, maintenance, and plant management personnel everywhere.

Markets and Applications for Thermal Flow Meters

Thermal Flow MeterInsertion, in-line, multipoint & portable thermal flow meters are used for monitoring and measuring industrial gas flows for stacks, ducts, flares, emissions, biogas, chemical processes, condensing gases, and pressurized gases. They provide the dependability required for most challenging industry requirements and are perfect for applications that call for reliability, exacting accuracy, cost-effectiveness. Below are the primary industries and their associated applications where thermal flow meters are found.

Coal Power

The increasingly stringent environmental and pollution requirements in the U.S. have resulted in a declining use of coal. However, coal remains the most common fuel source for generating power (mostly in specific industry applications), and more than 90% of the coal mined in the U.S. is used for generating power.

Coal Power Metering Applications Include:

  • Hot and cold pulverizer Air
  • Primary Air
  • Fuel air flow   
  • Secondary or underfire Air   
  • Tertiary or overfire Air
  • Baghouse airflow
  • Exhaust/emissions flow

Incinerators

Incineration (also called gasification, pyrolysis, plasma arc, and waste‐to‐energy) is the thermal treatment of disposed waste materials, converting it to ash, flue gas, and heat. Incineration reduces the original waste mass by up to 85% and the volume up to 95%. Flue gases are cleaned or burned before the final emissions are released into the atmosphere.

Specific Incinerator Installations:

  • Monitoring primary and secondary air to the furnace
  • Measuring combustion air to a boiler
  • Monitoring stack flue gas
  • Measuring and monitoring emissions

Landfills

Landfill gas falls into five basic monitoring categories: soil gas, near surface gas, emissions, ambient air, and facility air. Soil gas, emissions, and facility air are environments suited for thermal mass flow devices. Thermal technology is excellent for measuring extremely low flows and is known for having very low pressure drop.

Standard thermal flow meters do not work well in condensing gas environments, such as those found in landfill methane recovery systems. The unpredictable moisture levels caused by leachate, rain, temperature, and humidity add to the accuracy issues related to wet gas flow measurements.

Specific Landfill Installations:

  • Measuring emissions
  • Air monitoring spot checks across cells
  • Measuring gas conversion utilized in electricity generation
  • Supporting fuel cell management
  • Post‐combustion emissions

Metal Industries

This category includes primary and secondary industrial metal sources such as smelters, foundries, metal refineries, steel mills, and metal recyclers.

Specific Installations in Metal Industries:

  • Measuring furnace air
  • Measuring combustion air to blast furnace
  • Natural gas, combination air to blast furnace and reheat furnace
  • Monitoring exhaust, stack, and emission gases
  • Baghouse flow
  • Argon or chlorine gas flow, SNIF process in Basic Oxygen Furnace (BOF) area
  • EPA Method 14 stack flow (aluminum only)
  • Nitrogen blanketing
  • Continuous caster pneumatic systems
  • Coater line exhaust flow

Petroleum & Petrochemicals

The petrochemical industry creates products from petroleum that includes oil and gas. But petroleum is also used to create ethylene, propylene, benzene, toluene, and xylene — all of which provide the building blocks for solvents, dyes, detergents, fertilizers, adhesives, rubbers, plastics, resins, synthetic fibers, lubricants, and gels.

Specific Installations in Petroleum & Petrochemicals:

  • Measuring combustion air to a boiler
  • Measuring gas to flares
  • Monitoring stack flue gas
  • Measuring emissions (CEM)
  • Measuring combustion fuel‐to‐air ratios
  • Monitoring low‐pressure hydrocarbon storage vessel vent lines
  • Monitoring high‐pressure distillation column off‐gases
  • Monitoring very‐low flow for stuck open relief valves alarms
  • Monitoring knockout drum relief valve switch to the flare

Pulp & Paper

Creating paper pulp relies on a careful balance of low velocity air flows among the various processes. For example, the recovery boiler following the digester must be modulated to follow changes in the digester load. Other imbalances can create excessive amounts of pollutant gases, reduce chemical recovery efficiency, reduce the boiler’s steam production, create extra soot to coat boiler tubes, or cause excess corrosion problems for boiler components.

Specific Installations in Pulp & Paper:

  • Measuring combustion air to a boiler
  • Measuring primary/secondary/tertiary air to a recovery boiler
  • Monitoring stack flue gas
  • Measuring stack emissions
  • Monitoring digester gases and aeration air
  • Measuring inlet combustion air to gas turbine generator sets
  • Controlling tight fuel‐to‐air tolerances, such as with natural gas
  • Measuring turbine exhaust gases
  • Measuring overfire and underfire air

Wastewater

The primary applications in the wastewater environment are measuring blower air to each pool in the aeration basin and measuring digester gas flow. Operating the aeration blower accounts for up to 60 percent of all power consumed at a wastewater site, and proper air management can lead to massive savings in energy usage and equipment efficiency. Monitoring the health of the digester can provide indicators that minimize disruptions and leaks.

Flow Metering Applications in Wastewater Include:

  • Header (blower) air flow
  • Individual pool air flow in the aeration basin
  • Digester gas production
  • Precombustion engine fuel flow
  • Air/fuel to boiler or engine
  • Flare gas flow

FMCW (Frequency Modulated Continuous Wave) Open Air Radar Level Measurement

Non-contact level measurement using radar transmitters for the continuous, contactless level measurement of liquids, pastes, granulates, powders and other solids in a wide variety of industries.


Frequency Modulated Continuous Wave

OPERATING PRINCIPLE
  • The radar principle used is FMCW (Frequency Modulated Continuous Wave). The FMCW radar emits a high frequency signal whose frequency increases linearly during the measurement phase (called the frequency sweep). 
  • The signal is emitted via an antenna, reflected off the product surface and received with a time delay, t. 
  • Time delay, t=2d/c, where d is the distance to the product surface and c is the speed of light in the gas above the product. 
  • For further signal processing the difference Δf is calculated from the actual transmitted frequency and the received frequency. 
  • The difference is directly proportional to the distance.
  • A large frequency difference corresponds to a large distance and vice versa. 
  • The frequency difference f is transformed via a Fast Fourier Transformation (FFT) into a frequency spectrum and then the distance is calculated from the spectrum.
  • The level results from the difference between the tank height and the measured distance.
