The GC-THA online hydrocarbon analysis chromatograph can help you detect and predict in advance at any time, making it an indispensable choice for air separation explosion prevention!
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.
Product Features
- It can continuously monitor the sample of the gas to be tested.
- A fully automatic analysis instrument that can automatically schedule, sample, analyze, and achieve good separation and analysis results, with reliable data.
- It can achieve free switching between automatic and manual injection to obtain more reliable data.
- The instrument is easy to operate, and the injection and sampling time can be set arbitrarily.
- Measurement objects: Trace hydrocarbon content in the main cold liquid oxygen, storage tank liquid oxygen, and air.
- If the customer requires monitoring data, it can be uploaded to the air separation control room operation interface through 4-20mA;
- Supporting cabinets and necessary pre-processing systems;
- Meets the corresponding national standards and requirements.
