Process gas chromatography is used for separating and analyzing chemical compounds in the gas phase of industrial processes. Gas chromatograph instruments vaporize and distribute samples between a stationary and mobile phase, whereby a chemically inert gas carries molecules through a heated column.
Yokogawa gas chromatographs provide reliable and precise process analysis, with touch screen operation for effortless results. All chromatograph settings, displays, and data are truly segragated for easy understanding and maintenance. Since 1959, Yokogawa has supplied GC solutions to the oil & gas, refining and petrochemical industries around the world. Over the past 50 years, the GC products of Yokogawa have continued to evolve to meet the ever changing needs of the process industry.
The GC8000 has a built-in 12-inch color touchscreen display that dramatically simplifies operations. At the touch of the screen, the technician can access all of the analytical parameters and measurement results; displayed in easy-to-understand graphical color screens.
High volumes of volatile organic compounds (VOCs), typified by trichloroethylene and tetrachloroethylene, have long been used in various industrial fields for their high degrees of industrial usefulness. On the other hand, there is a growing awareness of environment preservation today, and of the fact that we face serious environmental pollution due to such harmful VOCs.
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.
Loek van Eijck, Yokogawa, The Netherlands, questions whether rapid analysis of gases and liquids can be better achieved through use of a gas chromatograph or near infrared analyser. Conventionally, the liquid and gas components such as those broken down by naphtha crackers have been measured by a process gas chromatograph (PGC), with the subsequent measurement values then being used for control purposes.
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.
To ensure peak performance, efficient GC maintenance is very important, especially now that many end users face a decline in supporting technical resources. In this webinar, we will show you how to optimize a GC maintenance plan.
You will learn:
- How to select the right sample system for your GC
- Installation considerations for optimal GC performance
- Best practices for maintaining a GC
