The TruePeak Tunable Diode Laser Spectrometers operate by measuring the amount of a laser light that is absorbed as it travels through the gas being measured. Involving 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).
Fired heaters are integral to industrial processes, including hydrocarbon processing and power generation. Specifically designed for the reaction of fuel and air to produce extremely high gas temperatures, heaters transfer this energy to potentially highly flammable process fluids via heat exchangers. They consume large quantities of fuel, produce large quantities of emissions and are a potential safety hazard to personnel and plant.
Yokogawa TDLS analyzers help control fired heater combustion with ever greater accuracy and reliability. There are measureable rewards for operating fired heaters at Low Excess Air (LEA) levels. In LEA combustion control, the lowest level of fuel is consumed and the products of combustion are cooled the least by unused excess air.
The cost benefits of these efficiencies are considerable, with just a single percentage saving in fuel enabling savings of tens or even hundreds of thousands of dollars per year. Controlling air levels just above the point at which incomplete combustion starts also enables the "cleanest burn," helping plants meet environmental emissions requirements. This in particular reduces the emission of NOx.
The ammonia (NH3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH3 analyzers that perform measurements indirectly, NH3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement. The TDLS200 Laser Analyzer is the solution to all these problems.
In maintaining and managing industrial plants, monitoring waste water pH/ORP is both a legal obligation and an unavoidable necessity for protecting the environment. Monitoring without an attentive eye can lead to severe consequences.
Considering safety and environmental issues such as combustion efficiency and decreasing NOX and CO in exhaust gas, it has become important to control O2 concentration in garbage incineration processes.
Cement is made by heating calcareous and argillaceous materials to a temperature between 1100 and 1500 °C. As this process uses massive amounts of energy, various energy saving measures are taken, including the measurement of oxygen concentrations in exhaust gases to control combustion.
Reduction of air pollutant emissions is essential to protecting the environment and this is an issue that concerns all industries. Efforts are being made to reduce the emission of harmful substances from municipal refuse incinerators by measuring concentrations of components such as NOx, SO2, CO2, and CO in their exhaust gases.
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.
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.
Spectrometric technology can assess many critical characteristics about products, but it has limits. It can be challenging to determine when the line has been crossed
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.
