Overview

Artificial gas analysis dedicated gas chromatograph

Product Details

Introduction:
The gas produced by the dry distillation, vaporization, or cracking of solid fuels such as coal and coke, or liquid fuels such as heavy oil, is collectively referred to as artificial gas. According to the production method, it can generally be divided into dry distillation gas and vaporized gas (generator gas, water gas, semi water gas, etc.). The main components of artificial gas are combustible gases such as alkanes, alkenes, aromatics, carbon monoxide, and hydrogen, and contain small amounts of non combustible gases such as carbon dioxide and nitrogen. The calorific value is 16000 to 24000 kilojoules per cubic meter. This experimental method is based on the different composition of refinery gas samples, using the "three valve four column dual thermal conductivity" analysis method to separate two different carrier gases carrying samples in different chromatographic columns, and then enter the corresponding thermal conductivity detector. According to the different thermal conductivity coefficients of different components, electrical signals of varying sizes are generated, which are processed by a chromatographic workstation to obtain the analysis results of the corresponding components. The entire analysis process is automatically completed. This method fully complies with GB/T10410.1-1989. The artificial gas analyzer is mainly used in coal mines, connected coal plants, etc
