Oxygen analysis – How to choose an oxygen analyzer?

How to choose the right process oxygen analyzer for your application? When selecting a gas analyzer for oxygen analysis, you may not be sure which one is the best for your requirements or process. Choosing the right oxygen analyzer for your specific application goes beyond specifications which don’t show the complete picture. Oxygen measurement performance for your process sample or what is necessary for uninterrupted all year operation are just some examples of criteria which can’t be found on the datasheet. Therefore, it’s crucial to understand the functionality and performance of the instrument from a complete process view.

Oxygen and combustibles in short

Oxygen is the most important gas of our planet; as useful to many industries as it is to nature itself. It converts combustibles into an energy source. It is used in the synthesis of countless chemicals. Its oxidizing power can also be a threat to catalysts and industrial assets. One needs to know the right oxygen concentration.

Types of oxygen and combustion gas analyzers

Zirconia oxygen analysis

Zirconium oxide is a trusted, industry-proven sensing technology for fast and accurate oxygen analysis in a wide range of applications, particularly combustion processes. Capable of measuring oxygen at percentage or parts-per-million levels, zirconium oxide sensors can be used in both extractive and insitu probe instruments, providing solutions for a wide range of industries.

Paramagnetic oxygen analysis

Paramagnetic oxygen analyzers measures the concentration of oxygen based on the fact that a magnet attracts gaseous oxygen. Whereas zirconia oxygen analyzers cannot measure oxygen in flammable gas mixtures, the paramagnetic oxygen analyzer can measure oxygen concentration in flammable gas mixtures.

Range of combustion and oxygen measurement applications

Biomass boilers

Biomass boilers provide the power and steam needed for many industrial processes. Efficient burner control ensures reduced fuel costs and lower emissions, and depends upon optimizing the combustion reaction between oxygen (from air) and the fuel used. An ideal ratio between the two ensures safe and efficient operation with minimal greenhouse gas emissions.

Combustion control

The key to combustion efficiency is to find the optimum ratio between air and fuel in the combustion reaction. This requires, at the minimum, accurate monitoring of oxygen, and also benefits from additional measurements: combustibles (for process optimization) and methane/hydrocarbon (for safety).

Industrial boilers

Boilers are required to provide the power and steam needed for many industrial processes. Efficient burner control ensures reduced fuel costs and lower emissions, and depends upon optimizing the combustion reaction between oxygen (from air) and the fuel used. An ideal ratio between the two ensures safe and efficient operation with minimal emissions.

Fired heaters

Fired heaters are direct-fired heat exchangers that use safe, efficient, and controlled combustion to raise the temperature of feed flowing through coils throughout the heater. They rely on efficient combustion to reduce fuel consumption, minimize emissions and ensure process safety. Depending on the use, these are called furnaces, or process heaters, and are critical to hydrocarbon processing.

Thermal oxidizers

Thermal oxidizers are specifically designed for air pollution control, receiving many of the waste streams from the production plant.  Variability in the waste compositions requires constant adjustment of the burner air-fuel ratio, and the swift monitoring of oxygen levels ensures proper destruction removal efficiencies of all emissions.

Kilns

Combustion control is important in a kiln, but can prove challenging due to the high temperatures, high variability in fuel sources, and high levels of dust and particulate matter. Efficient control of the combustion processes in cement and lime production can help reduce the fuel costs involved in creating the significant amounts of energy required, and also lower emissions.

Continuous emissions monitoring

CEM systems constantly analyze gases to measure the released pollutants, demonstrating compliance. Equipment must provide stable, and accurate results that are not subject to cross-interference from other pollutants.

Oxygen monitoring

During the regeneration cycle, coke deposits are removed from the catalyst by oxidation. Measuring the oxygen content at this stage is critical to minimize thermal damage, maximize the catalyst lifespan and optimize process efficiency.

Product quality

By accurately and reliably regulating the air-to-fuel ratio in the final stage of the glass fiber process, the tensile strength, density, weight and insulation quality of the fiber can be controlled.

Oxygen concentration in dryers

Inert environments are often required for pharmaceutical production to control the organic solvent vapors released during drying. Monitoring the oxygen levels within the dryer safeguards against the risk of explosion.

Process oxygen monitoring

High-quality coke depends on the absence of oxygen in the coke oven. Changing oxygen levels need to be monitored and detected with a rapid speed of response.

Trace oxygen monitoring

Oxygen, from the air, is a key impurity in many cryogenic gases. To ensure product quality, it is important to monitor very low levels of oxygen within the gas stream.

Fiberglass is made from melted glass which is spun at high speed to create fibers. Specific measurements are needed to ensure product quality.

Ametek PreMix 2000 air fuel ration oxygen analyzer for premix burners

Ametek PreMix 2000 air fuel ration gas analyzer for premix burners
Ametek PreMix 2000 air fuel ration oxygen analyzer for premix burners

The PreMix 2000 analyzer accurately and continuously measures the proportions of oxygen (O2), and fuel in pre-mix gases, operating in either excess fuel or excess air conditions. The analyzer is fed a small sample of the air/fuel mixture, burns it and then measures the net O2
or net excess fuel content of the mixture.

Operation

Most of the sample gas entering the analyzer passes through the bypass flow meter, which ensures a fast response and keeps the sample inlet purged of dead volume. A small portion of the sample flows through the sample flow meter and flashback arrestor to the furnace.
An igniter at the inlet of the furnace enables the fuel mixture to burn. The products of combustion then flow past the zirconium oxide cell, where they are measured.

Control unit

The PreMix 2000 uses the Series 2000 control unit. This state-of-the-art microprocessor control unit provides software selectable calibration options, and extensive analog and digital I/O capabilities, including a bi-directional RS-485 communications port.

Some combustion processes, e.g. process heaters, steam boilers or heating furnaces the air required to achieve optimal system efficiency can easily fluctuate. And the economic optimum of the process fluctuates within a relatively narrow range.

Both elevated NOx or SOx emission due to excess supply of air (O2 excess), as well as energy loss within the system due to incomplete combustion (lack of O2 ) require measuring the oxygen level in the flue gas of the combustion process.
