Process Gas Chromatographs

What is a Process Gas Chromatography Machine?

Gas Chromatography MachineProcess gas chromatography is used for separating and analyzing chemical compounds in the gas phase of industrial processes. Since the mid-twentieth century, the gas chromatograph has made a name for itself as a do-all analytical instrument with analysis capabilities ranging from percent level to ppm. Traditionally, field gas chromatographs have been used in the hydrocarbon industry, but have expanded to use in a wide range of industries from chemical process to power.

Descripción General:

Environmental pollution caused by volatile organic compounds (VOCs) has become a global environment issue, including issues on effects upon health. This paper introduces a system based on detection and sampling technologies and developed for measuring goes in the global environment. Small amounts of VOCs are measured with a gas chromatograph or photoionization detector (PID). VOCs in water are sampled using a sparging method. A small quantity of VOC constituents of more than 20 different types can be measured with a gas chromatograph using a programmed temperature oven. The PID can detect a ppb level of VOCs that are ionized using a vacuum ultraviolet radiation lamp. We expect these devices will be useful for improving the global Environment.

Descripción General:

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.
