TUNABLE DIODE LASER GAS ANALYSIS ISSUE: 42 COMPACT, FAST-RESPONSE MEASUREMENTS Discover the SERVOTOUGH Laser 3 Plus range REDUCING NOx EMISSIONS TDL sensing solutions for ammonia slip Combustion control and process efficiency

GAS ANALYSIS TECHNOLOGY WITH LASER PRECISION Welcome to Issue 42 of our Expert Solutions (ES) magazine, which focuses on Servomex’s innovative Tunable Diode Laser (TDL) sensing technology, related products, and the applications where TDL analyzers are most effective. TDL sensing is highly specific to the gas of interest, and can be optimized to measure a range of gases. It powers the revolutionary SERVOTOUGH Laser 3 Plus range, with models designed for combustion monitoring, process control, and environmental measurements of ammonia. In this issue, we look at each of these analyzers, and highlight...

PRODUCT FOCUS MEASURING OXYGEN FOR SAFETY, EFFICIENCY, AND CONTROL FAST, ACCURATE PROCESS CONTROL MEASUREMENTS Oxygen (O2) is one of the most prevalent gases on the planet, making up approximately 21% of the Earth’s atmosphere, and is essential to human life. This makes it vital to many medical gas applications, but it is also widely measured in industry, with applications within the production of metals, plastics and power generation. The extensive range of oxide compounds used in many processes means that there are many applications where O2 measurements are crucial for process control, safety,...

TECHNOLOGY FOCUS SENSING TECHNOLOGY FOR FAST-RESPONSE MEASUREMENTS Tunable Diode Laser (TDL) technology offers a fast-response, accurate measurement that is highly specific to the gas of interest. TDL sensors use a single-line “monochromatic” spectroscopy technique that provides highly stable calibration, a continuous, fast, in-situ measurement, and the avoidance of cross-interference from other gases. The TDL system consists of a laser light source, transmitting optics, an optically accessible absorbing medium, receiving optics, and detector. The signal information is held in the gas absorption...

PRODUCT FOCUS Monitoring carbon monoxide (CO) levels is a key factor in optimizing combustion efficiency. In addition, a fuel-rich environment contains high levels of both CO and methane (CH4). This is a constant risk and potential source of explosion, carbon monoxide and methane analysis is an essential safety monitoring requirement. Low-NOx burners are highly effective at reducing unwanted emissions, but run a cooler, larger, more complex fame that is less stable than older burners. This flame instability has led to the need to improve flame-out detection Changes to the ambient conditions,...

APPLICATION FOCUS Process heaters are designed to burn a fuel source in the presence of oxygen, generating heat for use elsewhere in a process. They consume large quantities of fuel, produce unwanted emissions, and are a potential safety hazard for personnel and plant alike. These properties make process efficiency a key concern. The key to combustion control, and reducing harmful emissions, is to optimize the air-to-fuel ratio within process heaters. Using excess fuel - referred to as fuel-rich conditions - is inefficient, costly, and unsafe, while using excess air is safer, but more inefficient....

PRODUCT FOCUS MEASURING AMMONIA FOR EFFICIENCY AND EMISSIONS REDUCTION Ammonia (NH3) is a colorless gas with a pungent odor, and is highly soluble in water. It is widely used in various industrial processes due to its unique properties and versatility. In power plants and various other combustion processes, the removal of waste NOx is typically achieved by DeNOx processes, where NH3 is injected into the flue gas flow from combustion, reacting with NOx to form water (H2O) and nitrogen (N2). Unreacted NH3 is commonly referred to as ammonia slip, and is generally held to <2 parts per million (ppm)...

APPLICATION FOCUS Reducing emissions of oxides of nitrogen (NOx) is a key objective for meeting environmental legislation, and an area of growing importance for power generation and hydrocarbon processing markets. It is important to effectively control NOx to meet legislative requirements and avoid fines; in addition, effective management has important benefits for the effectiveness and efficiency of a combustion process. In power plants and various other combustion processes, the removal of waste NOx - referred to as a DeNOx process - is typically achieved by selective catalytic reduction (SCR)...
