In a commercial-grade hydrochloric acid (HCl) production process, a synthesis unit utilizes a 2000°C top-fired combustion chamber made from impervious graphite (steel-jacketed) to process hydrogen and chlorine. The unabsorbed HCl gases are subsequently directed to a Tail Gas Tower (TGT), where the majority of HCl traces are absorbed. The remaining vent gas, which contains trace amounts of HCl (<5 ppbv) and water vapor, is then vented out of the system.

Challenge:

The customer encountered difficulty in installing a flowmeter for measuring the vent gas, which contains:

Trace amounts of HCl (<5 ppbv).

Water vapor.

Very low gas velocity.

The customer reported that no existing flow measurement solution was capable of handling these specific conditions effectively, particularly due to the corrosive nature of HCl and the low velocity of the vent gas.

Proposed Solution:

After thorough analysis of the customer's requirements and challenges, the expert proposes a customized flow measurement solution that incorporates a HALAR-coated sensor probe.

HALAR coating (perfluoroalkoxy) offers several advantages:

Chemical Resistance: HALAR is known for its excellent resistance to a wide range of chemicals, including hydrochloric acid. This makes it an ideal choice for the sensor probe exposed to the corrosive vent gases.

Water Vapor Compatibility: The coating also performs well in environments containing water vapor, preventing issues such as condensation or corrosion in the measurement system.

Durability: The HALAR coating enhances the longevity and durability of the sensor probe, especially in the harsh conditions of the vent gas stream.

The wetted parts of the flowmeter, which come into direct contact with the vent gas, will be coated with HALAR to ensure they can withstand the corrosive effects of HCl and water vapor. This customized solution will allow for accurate flow measurement, even at very low gas velocities, while also ensuring the longevity of the equipment.

The HALAR-coated sensor probe provides a practical and durable solution to the flow measurement challenge in the vent gas stream, offering accurate results while withstanding the harsh chemical and environmental conditions. This customized approach ensures reliable operation, even in a challenging industrial setting where traditional flowmeters would not perform adequately.https://leomi.in/vent-process-gas-flow-measurement-in-chemical-industry/

Why Is The Actual Mass Flow Rate Important In Gas Flow Measurement?

Measurement of gas mass flow under process circumstances is never easy. To do it, there aren't many flow methods available, such thermal mass calorimetry and coriolis flow.Gas mass stays constant but gas volume changes in response to changes in temperature and pressure, according to Charles & Boyle's law. This is the primary justification for why it's crucial to determine actual mass flow rate during procedures.

First, let's examine the distinction between Standard and Actual Flow Rates.

STANDARD FLOW RATES:

Standard flow rate is a flow rate of gas at specific pressure and temperature conditions. It is dependent on pressure and temperature conditions. It is termed as Standard volumetric (Sm3/hr or SCFM) or Standard Mass flow rate (Kg/hr at specific standard conditions).

There are different standards conditions used internationally such as :

ISO2533 (1.01325bara @ 15°C );

DIN 1343 ( 1.01325bar @ 0°C);

Standard (1.01325bar @ 20°C) etc. (above with 0% relative humidity conditions generally or sometime varying conditions )

ACTUAL FLOW RATES

Actual Flow rate is a flow rate of gas at different pressure and temperature conditions, It is independent of pressure and temperature conditions. It is termed as Actual Volumetric ( Am3/hr or ACFM ) or Actual Mass Flow Rate (Kg/hr at actual process conditions)

IMPORTANCE OF ACTUAL MASS FLOW RATE MEASUREMENT

As per Charles Law states that at constant pressure ideal gas volume increases with increase in temperature or gasses expands when heated.

And Bolye’s Law asserts that at a fixed temperature ideal gas volume is inversely proportional to pressure imposed on the gas. It suggests at constant temperature volume increases when pressure falls and gas volume decreases when pressure increases.

According to the aforementioned laws, measuring the volumetric gas flow rate results in a significant measurement inaccuracy because the volume of the gas changes as temperature and pressure do.

In order to accurately monitor and regulate the process conditions, we must ascertain the real mass flow rate of gas.

The Leomi 587 Insertion Thermal Mass Flow Meter for Actual Mass / Volume Flow Rate measurement was created with the process industry's actual need for precise and genuine measurement when improving process conditions in mind.

Why is the Actual Mass Flow Rate Important in Gas Flow Measurement?

Gas mass flow measurement is always a challenge in process conditions. There are very few flow technologies available for achieving it such

HOW TO MEASURE COMPRESSED AIR FLOW ACCURATELY & EFFICIENTLY?

In many industrial applications, compressed air flow is essential for running pneumatic tools and machinery and carrying out necessary tasks during processes or manufacturing. Since compressed air is frequently one of the more expensive energy sources used in a facility, controlling its utilization can be difficult. Precisely measuring the compressed air flow rate is essential to controlling the use of compressed air.

WHY ACCURATE MEASUREMENT OF COMPRESSED AIR IS IMPORTANT?

For industrial facilities, precise compressed air flow measurement is crucial in a number of ways.

Optimizing compressed air system performance: By keeping an eye on the flow rate, facilities can spot and fix leaks, modify compressor settings, and utilize less air than is necessary. Since compressed air is frequently one of the more expensive energy used in a facility, this can lead to significant cost savings.

Increasing Process and Equipment Efficiency: For instance, meticulous control over the compressed air flow rate is necessary in a paint spray booth to guarantee uniform paint application. Paint will not be applied evenly and with poor atomization if the flow rate is too low. Paint will be over-atomized at an excessive flow rate, wasting paint and raising expenses.

Compliance with Industry Standards: In order to comply with industry standards and laws, such as ISO 50001 for energy management and OSHA rules for worker safety, accurate flow measurement is also required.

Leak Detection and Reduction: Accurate flow measurement makes it possible to monitor compressed air usage in real time, and a higher turndown ratio makes it easier to find and fix leaks in compressed air systems, which lowers expenses and energy usage.

Energy Management: Precise flow measurement is necessary to monitor compressed air system energy consumption and manage energy effectively, which helps facilities reach cost and energy efficiency goals.

WHAT IS INSERTION THERMAL MASS FLOWMETER?

One of the most trustworthy and accurate methods for determining the flowrate of compressed air these days is to use insertion thermal mass flowmeters. The flow of actual gases, including compressed air, is measured by these meters using the thermal dispersion concept. According to King's Law, a thermal sensor with two PT-100 sensors—one for a heater and another for a reference—installed in a compressed air pipeline maintains a constant difference temperature. The cooling impact of the heater sensor is directly proportional to the air mass flow rate, and this relationship holds true for heater power consumption as well. The power consumption of the heater is directly correlated with the rate of change in mass flow rate. Thermal mass flowmeters inserted into the body have a greater turndown ratio, NO pressure drop, and excellent accuracy.

CONCLUSION

All things considered, precise measurement of compressed air flow is necessary to maximize the performance of compressed air systems, increase productivity, and guarantee the security of industrial processes. With their great precision and zero pressure drop, insertion thermal mass flowmeters are the perfect tool for monitoring compressed air flow. For industrial establishments looking to lower energy costs and consumption, increase equipment and process efficiency, and guarantee operational safety, they are the perfect answer.

ADVANCEMENT IN AIR & PROCESS GAS FLOW MONITORING IN CEMENT PLANTS FOR PROCESS OPTIMIZATION

One of the essential foundational industries for the growth of infrastructure and building is the cement industry; in 2021, the globe produced about 4.4 billion tons of cement. China is the world’s largest cement producer, with over 55% of the global capacity; India comes in second, with over 7% of the global capacity.

Following the COVID-19 epidemic, there was an abrupt increase in demand for both urban and rural infrastructure expansions worldwide, primarily in developing nations. Long-term demand for cement products will result from initiatives like India’s Smart City project, which will push current cement plants to greatly upgrade their technological capabilities in order to optimize energy and cost.

Among all industrial sectors, the cement industry is one of the ones that uses the most energy. Between 40% and 60% of industrial expenses are attributed to energy use. In addition, the cement sector accounts for 5% to 8% of global emissions of CO2 produced by humans. Today’s cement plant operators will prioritize efficiency and optimization due to the rising demand, which will primarily rely on the precise and repeatable measurement of several process parameters like temperature, pressure, flow rate and level, etc.

In the cement industry, process gas flows are typically calculated using temperature and pressure in relation to the speed and power consumption of fans and blowers. However, this is an assumption that creates significant uncertainty regarding the real gas flow rate and energy consumption of prime mover, such as fans and blowers.

The following processes require the best possible control over air and process gas flow monitoring in order to improve cement quality overall, efficiency, and cost optimization:

1. PREHEATER PROCESS EXHAUST GAS FLOW RATE MEASUREMENT:

Before the raw mix is put into the rotary kiln in a cement production facility, it is heated in cyclone preheaters, which also remove water and carbon dioxide from the mixture. The stability of the calcining temperature and the quality of the cement clinker in the kiln are directly impacted by the caliber of the preheater in a cement plant. The ID Fan downstream can be fine-tuned for optimal management of the O2 content of the kiln off gas by measuring the exhaust gas flow rate in the downcomer.

The measurement of exhaust gas flow is often difficult because of the duct’s enormous diameter, the high concentration of dust, and the high temperatures (between 350 and 400 degrees Celsius). Velocity is typically measured momentarily using a Pitot tube with large uncertainty for cross-checking, which hinders effective process management.

2. CLINKER COOLER AIR FAN FLOW RATE MEASUREMENT:

A crucial component of the clinker manufacturing line, the clinker cooler provides hot air for the rotary kiln and preheater system as well as aids in cooling and transporting the hot clinkers that are discharged from the kiln. It is essential for decreasing the amount of coal and power used, raising the temperature of secondary and tertiary air, and enhancing the rate of heat recovery since it is the first piece of equipment where high-temperature clinker releases heat.

Two ways that a good clinker cooler can assist cement plants in reducing energy consumption are by increasing the cooling efficiency and lowering the power consumption of the clinker cooler itself, and by increasing the heat recovery rate, which can lower the amount of coal used in the rotary kiln and preheating systems. In order to achieve cooling efficiency and energy savings with a higher cooling rate concerning feed rate adjustment, clinker cooler grate air fan effective management is essential. For a clinker cooler to operate as efficiently as possible, continuous cooling air flow rate measurement is crucial.

Because of the high concentration of clinker dust and high abrasion rate, measuring a cooler air fan is a difficult operation. Strong flow sensors that are resistant to severe abrasion are required. This application’s flow solution is currently restricted, and its life expectancy is only 1–6 months.

3. AQC BOILER & PHP PROCESS GAS OUTLET FLOW MEASUREMENT:

The heat produced by the rotary kiln preheater (PH) and the hot gases from the AQC exhaust are used to create power in waste heat recovery (WHR) power plants, which are situated in cement factories. Waste heat recovery systems (WHRS) use steam turbines to recover heat energy from hot waste gas that is sent to boilers for power generation (in this case, electricity) and after quenching chambers (in this case, clinker cooler and preheater boilers in rotary kilns. Usually, this waste heat can be used for power generation applications to meet the cement plant’s 20–30% power need, which results in a significant reduction in the overall cost of production.

Effective management of pH and AQC A flow measurement device that is appropriate for high temperatures and abrasion resistance design is required by the boiler in order to ensure an accurate and dependable gas flow rate at the intake or output.

4. PRIMARY AIR FAN FLOW MEASUREMENT IN POWER GENERATION BOILERS:

In addition to AQC & PH Waste heat recovery boilers, a captive coal power plant is erected in the cement plant to provide additional electricity needs. It’s critical to keep an eye on the boiler’s primary airflow in order to maintain the ideal stoichiometric air-to-fuel ratio and achieve effective combustion. It is necessary to have a primary air flow measurement that is accurate, dependable, and low-maintenance. It should also have a minimal pressure drop.

5. PROCESS & FLUE GAS FLOW MEASUREMENT IN EXHAUST STACK:

For the purpose of maintaining control over emission criteria, the pollution control authority must monitor the exhaust process flue gas from the boiler and clinker cooler. In order to achieve high thermal efficiency, enhance ESP performance, minimize emissions of dangerous pollutants, and provide helpful information on optimizing mass balance, this requires accurate and dependable flow measurement technologies.

6. COMPRESSED AIR MEASUREMENT FOR UTILITY CONTROL AND CONSERVATION:

AN ACCURATE AIR & GAS FLOW MEASUREMENT IN CEMENT PRODUCTION HELPS IN:

Reducing Blower (ID/FD Fan) power consumption i.e., energy saving

Controlling the accurate and repeatable operation of kiln & improving clinker production quality

Improves energy efficiency of Clinker cooler fan & energy conservation

MAJOR CHALLENGES IN EXISTING FLOW MEASUREMENT SOLUTIONS FOR THE ABOVE APPLICATIONS:

High-pressure drop means energy loss

Lower turn-down ratio implies limited operational range and leakage insensitive.

Lower accuracy & measurement resolution implies limited efficiency & performance analysis

Clogging and high wear factor

High cost of installation & needs frequent maintenance.

OVERCOMING ABOVE CHALLENGES BY ADVANCE PROVEN CALORIMETRIC (HEAT DISSIPATION) TECHNOLOGY:

The technology of Insertion Thermal Mass (Heat Dissipation) Flow Meters is advancing these days to overcome the drawbacks of the traditional pitot tube or annbar differential pressure-based flow measurement methods now in use.

NSERTION THERMAL MASS FLOWMETER:

WORKING PRINCIPLE:

The fundamental principle of thermal dispersion from a heated element to the ambient medium (such as air or gases) underlies the operation of thermal mass (calorimetric) flow meters. The velocity, density (temperature and pressure), and properties of the medium all have an impact on this. The mass flow and temperature differential, ∆T, determine how much energy is required.

ADVANTAGES OF INSERTION THERMAL MASS FLOW METERING TECHNOLOGY AGAINST CONVENTIONAL FLOW METERING:

Pipe sizes suitable 15mm to 10 metres

Easy Installation, orientation & rugged design with customized sensor material design

Working temperature upto 40⁰⁰C & 16barg or higher can be achieved

Better accuracy < ±2%RD of mass flow rate

Highest turn down ratio 100:1 or better, too sensitive throughout flow ranges.

No pressure drop saves energy (pressure) loss

Versatile & Cleanable sensors (auto-purging) design

Can be used with too low upstream straight length with special installation procedure

Low cost of ownership against other flow technology

CONCLUSION:

The main components of a cement plant are large ducts with blowers (FD & ID Fans). Conventional flow measurement uses differential pressure sensors as primary elements, such as average pitot tubes, orifices, and aerofoils, which are prone to clogging, insensitive to changes in flow velocity, and result in significant pressure drops with lower accuracy. It has now been shown that using differential pressure sensors against the latest development in heat dissipation technique — insertion thermal mass flow — is generally uneconomical when compared to inserting thermal mass flow (heat dissipation technique) metering.

Current research is being done to develop more materials that are compatible with hot gas that has high abrasion and heavy dust concentration. These materials will meet the majority of application needs in cement plants, with the exception of a few that have temperature restrictions up to 500°C. Conventional technologies continue to dominate the industry, with operating temperatures remaining above 50⁰⁰C. I hope this will assist operators of cement plants in seeing the advantages of utilizing modern technologies in place of traditional flow measurement.
