Model: GC2010B Trace Hydrocarbon Analyzer
Air separation method is currently a main solution for industrial production of oxygen, nitrogen and argon. However, due to air pollution, the raw materials containing hydrocarbon enters into air separation equipment, which directly threats the safe production. If concentrations of hydrocarbon exceeds the limits, the air separation equipment will explode consequently. Therefore, it is very important to know the compounds and concentrations of hydrocarbon to properly evaluate and control production process.
1 Application
GC2010B trace hydrocarbon analyzer is an enhancement type based on model GC2010A. It automatically and continuously analyzes trace hydrocarbon compounds and concentrations in liquefied oxygen, liquefied air during air separation process. Real-time monitors variation of concentrations of C1 - C4. Provides important data for safety operation of air separation equipment. It is also used in petrochemical industry, steel industry, gas industry and refinery plant to measure hydrocarbons. GC2010B is equipped a small sample worker which can absorb hydrocarbons by changing of temperature. These hydrocarbons are desorbed in heating oven, and then injected into analyzer for measurement. This process can increase measurement sensitivity (The minimum detection concentration of C2H2 can reach 0.001ppm by this method.).
