Tunable Diode Laser Spectrometers

Ensure minor issues in Vinyl Chloride Production can be identified before becoming serious problems with Yokogawa’s In-Situ Gas Analyzer TDLS8000 and Probe Type Analyzer TDLS8200.

An in-situ TDLS8000 installed on a process leg or bypass stream provides a reliable and high-speed measurement that is representative of the process composition.

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.

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. 

Yokogawa’s Tunable Diode Laser Spectroscopy (TDLS) is the ideal solution for both oxygen and carbon monoxide measurements in process furnaces that have aggressive and corrosive components.

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.

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

Tunable diode laser analyzers optimize combustion through direct measurement of O₂, CO and methane.

SABIC Turns to Yokogawa TDLS Analyzers to Enhance Safety Functions and Production

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.

The EPA rule, 40 CFR 63 Subparts CC and UUU, is forcing refineries to monitor flares. Fortunately, modern analyzer technology makes it possible to meet the requirements, generate the necessary reports, and stay in compliance.
Here’s how to select the right analyzer to meet these demands.
