Yokogawa TDSL8000 and CO + CH4 measurements provide reliable information to achieve:
O2 Measurement for Safety and Process Monitoring & Control Yokogawa TDLS8000 02 analyzer achieves:
O2 and HCl measurement at waste incinerators
Since this is a non-contact measurement, the measurement of exhaust gas from waste incinerators, which have a large amount of dust and corrosive components, is not problematic with TDLS™. In addition, since measurement can be performed at high temperatures, measurement and high-speed control can be realized in the vicinity of the combustion section, thereby improving the operating efficiency.
O2 was measured for safety and quality control at chemical plants and steel works.
The TDLS eliminates the problems of maintaining sampled filters, delaying responses, and interfering gases.
O2 and CO were measured to monitor the fire prevention of coal and pulverized coal storage.
Temperature and CO-measurements are essential for detecting the ignition of coal and bag filters in storage tanks.
The reference cell can stably measure low concentrations, which were Display at 0% in other products. High-speed measurement is possible without concern of dust clogging.
Black liquor recovery boiler in paper mill and H2S and HCl measurement in distillation kettle.
The most suitable TDLS for measuring the H2S of the exhaust gas from a soda-recovery boiler is a non-contact, sampling-free, easy-to-maintain OOC that does not require any clogging, in order to monitor the sulfur components, which is the source of the odor, and to prevent explosions. In addition, HCl in the exhaust gas of boilers using waste as fuel is also measured at high speed and accurately.
H2O measurement for various moisture monitoring.
Measure the water content of the drying oven, such as cellophane, gypsum, plywood, paint, and food, from the % level of water to the ppm level of water in the manufacturing process, which is unpleasant.
O2 and CO were measured in an electric furnace.
It is possible to measure the O2 and CO of the exhaust gas generated in the electric furnace and perform melting without waste.
Exhaust gas from high-temperature and high-dust electric furnaces has proven to be an installation method to suppress the effects of the exhaust gas, and can be measured without problems.
This is a basic flow, although it differs depending on the customer's area and plant.

*Please tell us about the status of the plant in order to propose the best specifications for your application.
The items related to the status of the factory are as follows.
Return to the repair shop is unnecessary during maintenance. Parts can be replaced at the site and restored immediately.
* Since the TDLS is equipped with a self-diagnosis function and supports predictive maintenance, sudden stop of the plant can be avoided in principle.
Servicemans from all over the world are responsible for installation and installation.
The Process Insulation Flange protects the TDLS8000 from process gas pressures, heat, dust, and corrosive components from the process gas.
It can be used for protection during direct mounting or bypass mounting.
Use in the following cases.
YC8000 Flow Cell : Used to sample and measure gases at any location.
Calibration cell : Used for offline calibration and validation.
Unit connection cable : Used to connect the sensor control unit and the laser unit.
O-ring : Replace the O-ring when it is removed for periodic inspection, etc.
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.
H2S management of exhaust gas in black liquor recovery boilers is required to meet an environmental regulations.
Industrial Combustion sources such as thermal cracking furnaces and, process heaters play a critical role in the process industry.
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.
O2 measurement in hydrocarbon vapor is used for safety monitoring in vacuum distillation columns in petroleum refining. With conventional paramagnetic oxygen analyzers, O2 concentrations are obtained through an extractive sampling system, which conditions the sample prior to being analyzed.
If water is present after the dry chlorine tower in brine electrolysis plants, the downstream compressor is corroded or the product quality is deteriorated. The moisture level is measured before and after the compressor to prevent the corrosion of the compressor and the deterioration of quality.
O2 measurement is used to safely recover flue gas containing a high concentration of CO from a converter furnace. With conventional paramagnetic oxygen analyzers, O2 concentrations are obtained through a sampling system to recovery flue gas. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement.
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.
