Special gas chromatograph for trace hydrocarbon analysis in air separation

Introduction and Method Description of Gas Chromatography for Trace Hydrocarbon Analysis in Air Separation:

GC-9280The online air separation trace hydrocarbon analyzer is a specially designed analysis instrument based on chromatographic principlesinstrumentUsed for the analysis of trace hydrocarbons in Huai state oxygen in the main condenser of air separation equipment, it is a rare detection equipment for large, medium, and small air separation equipment manufacturers.

Air separation is currently the main method for industrial production of oxygen, nitrogen, and argon. Due to air pollution, hydrocarbons contained in the raw air enter the oxygen concentrator system, directly threatening safety production, and the situation is quite serious. In recent years, there have been hundreds or thousands of explosions in large, medium, and small air separation equipment both domestically and internationally due to excessive hydrocarbon content, resulting in astonishing direct and indirect losses. If detected at any time, the content of hydrocarbons can be predicted in advance, and measures can be taken early to prevent explosions. Trace hydrocarbon analyzer can help you detect and predict in advance at any time, making it an indispensable choice for air separation explosion prevention!

Special gas chromatograph for trace hydrocarbon analysis in air separationIt can continuously and automatically analyze trace hydrocarbons in liquid oxygen, liquid air, and suction air in air separation processes, and monitor explosive components C in real-timeThe changes in the content of 1-C4 provide important reference data for the safe operation of the main condenser in air separation equipment. It can also be used as a process controller for detecting hydrocarbons in industries such as petrochemicals, steel, and gas.

The trace hydrocarbon chromatographic analyzer is an automatic analyzer, and the pipeline extending from the air separation tower is connected to the instrument. The instrument is controlled by a microcontroller automation program to drive an automatic six way valve for sampling and injection. As long as the analysis conditions and program settings are set, it can automatically detect hydrocarbons in liquid oxygen without human supervision, and can also print out the experiment report directly to the experimenter.

Instrument features:

1. It can continuously monitor 1~32Sample of gas to be tested on the road.

2. It can automatically schedule, sample, analyze, print reports, achieve good separation and analysis results, and provide reliable data. It is a truly unmanned fully automatic analysis instrument.

3. It can achieve free switching between automatic and manual injection to obtain more reliable data.
