Tunable Diode Laser Spectrometers

What are Tunable Diode Laser Spectrometers (TDLS)?

Tunable Diode Laser SpectrometerOptimize combustion, increase throughput, reduce emissions, and increase safety

The TruePeak Tunable Diode Laser Spectrometers (TDLS) operate by measuring the amount of laser light that is absorbed as it travels through the gas being measured. The TDLS line offers measurements for process gas, flue gas, impurity analysis, custody transfer, safety, with in-situ and extractive methods supported. By utilizing no sensor contact with the process and no moving parts, it leads to a high mean time between failures (MTBF) and hence a low long-term cost of ownership (LTCO).

  • In-Situ Gas Analyzer TDLS8000

    Yokogawa’s new TDLS8000 houses all of the industry’s leading features in one robust device. The platform design is for in situ measurements which negates the need for sample extraction and conditioning.

  • Probe Type Gas Analyzer TDLS8100

    Yokogawa’s new TDLS8100 continues to house all of the industry’s leading features from the TDLS8000, but now only requiring a single-flange installation. An in-situ measurement with a probe removes the requirement for sample extraction and conditioning and can be used in a variety of aggressive process conditions.

In-Situ Measurement Allows for Quick Analyzer Response 

Tunable diode laser spectrometers (TDLS) allow for real-time gas analysis that leads to increased efficiency, safety, throughput, quality, and environmental compliance. The non-contacting sensor allows measurements in the most severe conditions, such as high temperature, high pressure, corrosive/abrasive conditions, and high dust loading. This in-situ analyzer eliminates the need for sample handling and extraction and reduces the need for routine maintenance and calibration.

>>> Application Notes

 

Improved OPEX and Safety


The TDLS8000 is attracting considerable attention from many refinery and petrochemical plants because it requires little maintenance and can measure the concentrations of O2 and CO/CH4 in the radiant section of large-scale combustion furnaces and process heaters in near real-time. This allows an unprecedented opportunity to optimize combustion efficiency leading to increased throughput, reduced emissions, and increased overall asset safety.

Overview:

Electrolysis plants create hydrogen and chlorine from a brine solution. Chlorine gas generated from the anolyte of the electrolysis tank generally contains between 0.5 to 2.0 vol% H2O. The sample is then cooled and filtered to remove brine, subsequently coming out as wet chlorine gas. The wet gas is sent to a drying tower where it is treated with sulfuric acid to get moisture down to the ppm level.

Tomando en cuenta las cuestiones ambientales y de seguridad tales como la eficiencia de combustión y la disminución de NOX y CO en los gases de escape, se ha vuelto importante para controlar la concentración de O2 en los procesos de incineración de basura.

Yokogawa Technical Report
Overview:

In recent years, shale gas extraction technology has made rapid progress, inducing a shale gas revolution mainly in the USA. Thus, the need for analysis of hydrocarbon gases, including natural gas, is expected to grow rapidly. Traditionally gas chromatography has been used for the analysis of hydrocarbon gases; it can accurately measure the concentration of each hydrocarbon component in a sample of natural gas.

Overview:

Combustion furnaces such as heating furnaces and boilers in plants include various sizes and types, and serve as energy sources, that is, they are cores in all production activities. Because a large amount of fuel such as gas or fuel oil is consumed in plants, their combustion efficiency directly affects the performance and running cost of the plants.

Overview:

With fired heaters, users hope to get greater efficiency and reduced emissions but often are disappointed. Given the number of fired heaters operating every day and their importance in the process industries, any improvements realized across the board will have huge impacts. More units can reach their potential with some simple changes in work practices and technology upgrades.
