Level Measurement for Water in Sewage Pools

Level Measurement for Water in Sewage Pools

This application takes place at a large power plant well known for its "Green Approach" and it's commitment to ensuring a clean and healthy atmosphere in and around the plant. 

The branched sewer system of the power plant requires instant maintenance and control. The plant uses water to operate the turbine. This water and other wastes move to the city’s wastewater treatment plant through the sewage system.

Some of the sewers are dispersed in remote locations around the plant, making it difficult for personal maintenance personnel to approach and repair damage on time. Plant technicians were looking for a solution to control the sewers better and avoid cases where wastewater might overflow. 

The sewage pool readings had to be transmitted to the central DCS because the sewage system connects to a central control room. The plant needed a 24/7 watch and an on-site guard to gain maximum control over those sewers. 

Technicians also stressed that wastewater flooding was inevitable because it takes time for the equipment to handle blockages. This flooding has caused severe damage to the environment. It was essential to control the wastewater level in the sewers to avoid cases such as these from reappearing. 

The Drexelbrook Usonic - The Solution 

After a lengthy examination of several possibilities, the plant decided to install two Drexelbrook USonic systems in its sewage pools. The ability of USonic to produce non-contact, continuous, and accurate readings of the water level in the pools gave the engineers of the plant a clear picture of the pools' status. 

Its compact size and integral construction simplify its installation, offering an efficient solution in no time at all. The USonic had no problem providing 12ft water level readings with a measurement range of up to 30 ft.  It can map obstacles in the pool and memorize interfering signals with its scan distance function. 

The USonic was linked to the central control system via 4-20mA, allowing the plant engineers to control the water level in the sewers constantly. The engineers know that the sewers would maintain the correct water level, and the system would be alerted in an emergency. 

Summary

The two USonic systems installed in the power plant give complete control over the sewers' water level to the plant's engineers. The systems' ability to display continuous level readings around the clock improved maintenance crews handle the sewage system.

To detect sudden blockages and avoid environmental damage on time, they can now save time. The plant received an immediate return on investment due to its compact size and reduced price.

A Free Technical Paper Explaining Refractive Index

Refractive Index

Refractive index measurement is a measurement of the speed of light in a medium. The speed of light (usually denoted by c) is 299 792 458 m/s in a vacuum. In other media, the speed of light is lower, and the refractive index (R.I.) of a medium is how much slower the light's speed is in the medium.

The detection of liquid concentrations by optical means is not new. The law of refraction was mathematically formulated first by Ibn Sahl in 984 but not known in Europe. Instead, its discovery misattribution goes to the Dutch astronomer and mathematician Willebrord Snellius (Snell), who rediscovered the law and published it in 1621. The first laboratory instrument to accurately measure liquids' refractive index was developed by Ernst Abbe in 1874.

This technical paper, courtesy of Vaisala K-Patents, is a technical explanation and understanding of the refractive index.

The Flow Safe F9000 "SurgeFlow" Liquid Surge Relief Valve

Liquid product pipelines must be protected from liquid surges. Surges are caused by pump failure, rapid block valve closing, non-return check valve hard-shutting, emergency shutdown of a tank or loading system, or even a pump coming on or tripping. The magnitude of surge pressures varies, some virtually undetectable to those severe enough to cause significant damage. These propagating waves, either increasing or decreasing rapidly, are commonly known as a transient hydraulic surge of water hammer that can cause severe damage to liquid product pipelines, vessels, flanges, valving, and associated equipment. 

The Flow Safe SurgeFlow series has been developed exclusively for liquid surge protection. These valves are extremely simple and 100% reliable. The dome cavity volume on top of the main valve piston is filled with nitrogen gas to affect the valve's proper set pressure. Dome gas pressure is set according to the characteristic piston seat-to-seal area ratio for the given valve size. This dome load forces the main valve into a closed position using a soft elastomer seat, providing a 100% tight shut-off. When surge pressure is sensed, the SurgeFlow valve piston opens immediately as the liquid fluid force acting under the piston overcomes the force from the dome gas working on the top. The piston continues to lift in proportion to the pressure surge, slightly compressing the dome gas. The closing cycle responds directly to pressure decay in the piping upstream of the SurgeFlow surge relief valve. 

SurgeFlow series valves are designed for accurate and repeatable performance. They will handle both minimum and maximum surge cases when called upon to relieve. Flow Safe suggests all surge relief valves be located nearest the point where maximum pressure can occur in the main pipeline for optimal safety purposes.

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.

Radar Level Measurement: Comparison of 24 GHz and 80 GHz

Radar level transmitters are among the most accurate technology choices for process level and storage tank applications for continuous level measurement under demanding conditions.  These transmitters utilize Frequency Modulated Continuous Wave (FMCW) technology that offers superior signal processing capabilities and more reliable measurement than other techniques. The state-of-the-art signal processing capabilities of these transmitters, along with their frequency range, helps to ensure optimum application coverage.

24 GHz radar transmitters cover a broad range of applications, including liquids & solids. 

80 GHz radar transmitters are especially beneficial for level measurements in narrow tanks with internal obstructions due to their small beam angle.

This video, courtesy of AMETEK Drexelbrook, demonstrates many of the other differences between 24 GHz and 80 GHz models of radar level transmitters.

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.
