Gas chromatography is one of the most widely used techniques for analyzing hydrocarbon mixtures. Some of the advantages of chromatography include a wide dynamic range of measurement (from ppm levels up to 100 percent), the detection of a wide variety of gas components, and the repeatability of measurements. Gas chromatographs are used in many applications, including product quality and process control, heating and energy measurement, as well as trace contaminant and environmental monitoring in many industries such as refining, power generation, gas processing, chemical and petrochemical.
Emerson’s Rosemount gas chromatographs (GCs) are equipped with the user-friendly MON software, giving operators the ability to easily configure, operate and manage the analyzer locally or remotely. It also provides analytics and greater insights into the process and the GC performance. Among the many features of the MON software is the ability to communicate across the enterprise network, securely store critical data, and generate detailed reports such as:
Any gas chromatograph is only as good as the quality of the sample it measures. So every sample system for Emerson’s gas chromatographs is custom engineered for the specific requirements of the application. Common features include:
The 6 or 10 port valves used in Emerson’s Rosemount gas chromatograph provide exceptional durability and low maintenance due to the unique double-sided diaphragm actuation, which eliminates the need for springs, o-rings and lubrication. Minimal movement of the internal components in the valve contributes to the rapid actuation of the valve which is ideal for applications using micro-packed and capillary columns. Other design features include:
Whether you need to network multiple process gas chromatographs throughout the plant or simply link a single analyzer to the DCS system, Emerson’s Rosemount gas chromatographs can be configured to handle most any communication scenario, including:
A gas chromatograph is a reliable method for identifying the compositional analysis of biomethane and monitoring its quality, calorific value and Wobbe index.
