Precise Real-Time Dry Flow Measurements for Landfill Pollution Reporting with Kurz Instruments Flow Meter

Flow Measurements for Landfill Pollution

Landfill gas (LFG) is a natural byproduct of the decomposition of organic materials in landfills. LFG is composed of roughly half methane (the primary component of natural gas), half carbon dioxide (CO2), and a trace of non-methane organic compounds. Over a 100-year cycle, methane is a potent greenhouse gas that traps heat in the atmosphere 28 to 36 times more effectively than CO2. 

Municipal solid waste (MSW) landfills are the third-largest source of human-related methane contamination in the United States, accounting for approximately 15.1% of total emissions in 2018. 

LFG pollution and methane migration into the atmosphere leads to local smog and global climate change.  Instead of escaping into the atmosphere, LFG can be collected, converted, and used as a renewable energy resource. 

LFG is removed from landfills using a network of wells and a blower/flare (or vacuum) system. The gas's ultimate use depends on to practicality of how the extracted gas transports to a central location where it can be processed and treated and then be flared or used in an LFG energy project. 

Many landfills install gas control controls due to regulatory requirements. The federal government enforces legislation that governs the use and maintenance of landfills. These regulations aid in controlling ozone precursors (volatile organic compounds and nitrogen oxides), methane, NMOCs, and odorous compounds from landfill gas emissions, which harms human health and the atmosphere. 

Thermal flow meter technology is perfect for these applications because of its low-pressure drop and ability to calculate very low flow volume. On the other hand, standard thermal flow meters generally do not perform well in condensing gas conditions, and applications such as landfill methane recovery systems cause problems with standard thermal flow meters. 

The unpredictability of moisture levels caused by leachate, rain, temperature, and humidity exacerbates the accuracy issues associated with wet gas flow measurements. A solution is the Kurz WGF flow meter. It is perfect for use in wet gas applications. Kurz allows you to quantify gas flow precisely and provide real-time dry flow measurements for pollution reporting (federal, state, local regulations, greenhouse gases, and the Landfill Methane Rule).

Webinar: Advantages of Ultrasonic Technology for Flare Apps in the Chemical, Petrochemical & Refinery Industries

Webinar

Flare stacks are used on nearly every oil and gas installation as part of the waste gas system and as a regulated vent for high volumes of combustible gases during an upset. The pressure, volume flow, and gas composition in a flare stack can vary significantly over short periods. Since its inception in the 1920s, ultrasonic technology has evolved for various applications, including the calculation of flare gas flow. Ultrasonic flow meters are well suited for reliable process monitoring of flares due to their precise measurement of flow rates ranging from almost zero to more than 120 m/s. Using ultrasonic flow meters ensures that the optimal ratio of O2 and steam to combustion gas is maintained and proper calculation of the actual amount of flared gas.

On April 22, 2021, ultrasonic flow meter manufacturer SICK Sensor Intelligence and industry publication Chemical Engineering are presenting "Advantages of Ultrasonic Technology for Flare Apps in the Chemical, Petrochemical & Refinery Industries."

Please reserve the date and join SICK Sensor Intelligence and Chemical Engineering for this webinar to learn about the latest developments and benefits of using ultrasonic technology for flare applications.

Infrared Pyrometers for Industrial Temperature Measurement

Infrared Pyrometers from Williamson

Temperature is one of the most commonly measured process variables in manufacturing operations. Proper temperature regulation and control are critical to product quality and process productivity.

Many applications use contact devices like thermocouples and RTDs. Still, these devices are too often inaccurate, too slow, difficult to use or require frequent replacement, creating process downtime and reducing productivity. For many applications, infrared pyrometers are the perfect solution because they can accurately and reliably measure a target’s temperature without contact.

Wavelength selection can dramatically reduce or even eliminate errors due to optical obstructions, emissivity variation, background reflections, and misalignment. Williamson offers six different types of infrared temperature measurement technology with various wavelength options, multiple optical configurations, temperature spans, and accessories to ensure each infrared thermometer receives the perfect setup for each application.

Level Measurement - Floating Roof Terminals

Level measurement Floating Roof Terminals

Designed for industrial applications and harsh environments., the LLT100  provides continuous, non-contact level measurement capabilities for process automation and inventory management. 

Terminals are critical for maintaining a steady supply for economies globally. Thus, there is a high emphasis on mitigating asset loss due to inclement weather, cross-contamination, overfilling, and fugitive emissions. The 2016 API Standard 2350 for overfill protection and prevention puts into place a standard for compliance. However, due to aging technology, the options for technology already installed were limited.

Level Measurement
Floating roof technology consisting of pontoons and seal liners. The floating roof is critical to prevent fugitive emissions and protect assets from contamination and the technology to monitor the height and pitch. However, most of this technology requires large targets to be mounted, and there are limited options for redundancy.

As we enter the 4th industrial revolution, predictive maintenance and early warnings will be crucial to automating an aging but critical part of global infrastructure. ABB has released a differentiating technology not reliant on float tape, large reflection surfaces for open path radar, and not dependent on specific gravity or dielectric constant. It can be mounted close to tank walls while eliminating time-consuming echo mapping and false echo suppression.

ABB's LLT100 series laser encompasses these qualities and offers a simple user interface for fast commissioning, and performs reliably without the need for calibration. It's the modern solution to enable terminals to comply with new API standards and add redundancy on mission-critical tasks. ABB has success-fully implemented this on multiple sites with results exceeding customer's expectations.

Precision Turbine Flow Meters Assist in Lower NOx on Gas Turbines

Turbine Flow Meters Assist in Lower NOx

As smaller power sources, gas turbine generators are cost-effective solutions. Packaged as systems, they offer flexibility and simplicity with a capacity of 20 MW to over 1000 MW. The gas turbine engine is proven and reliable technology that allows for relatively rapid installation of a complete package almost anywhere.

Regulatory agencies and manufacturers are examining emissions standards that further restrict the release of pollutants into the atmosphere and are increasingly developing systems to meet ever-tighter standards. In gas turbines, nitrogen oxides (NOx) resulting from the combustion of fuel and air, and any nitrogen component, are the primary pollutants produced. The turbine's firing temperature and the fuel used heavily influence a standard gas turbine's NOx emission.

One method of NOx reduction is water injection, used since the 1970s. Systems inject water vapor directly into the combustor of a  gas turbine, reducing the flame's temperature, which decreases NOx emissions in turn.

By injecting demineralized water directly with the fuel (natural gas, fuel oil, etc.), it achieves a reduction of turbine firing temperature, directly correlating to a decrease in NOx emissions. Demineralized water minimizes scaling and build-up in the nozzles and the combustion chamber. As the generator's load increases, additional water maintains the turbine firing temperature low enough to reduce NOx emissions to about 25ppm. The turbine flow meter measures the supply water flow rate to the nozzle injector manifold to control the feedwater valve position while monitoring the firing temperature. This application requires a very accurate flow meter for a precise control scheme.

The Flow Technology FT Series turbine meter with the LA-5 linearizing electronics and an extended range calibration to give a turndown of 100:1 over the flow range fits the bill.  Available with either meter-mounted or remote-mounted electronics and high temperature amplified pickoffs that eliminate noise generated by the floating (non-grounded) electrical system of the turbine generator. Additionally, the FT Series turbine meter can be placed inside the generator room due to its compact size and durability under extreme conditions.
