GB/T 28125.1-2011 Determination of Hazardous Substances in Air Separation Process Part 1: Determination of Hydrocarbons
This part specifies the method for the determination of liquid oxygen, liquid air, air at the suction port and hydrocarbons in the liquid oxygen tank in the air separation process. This section applies to online monitoring and offline detection of total hydrocarbons and C1~C4 hydrocarbons in oxygen or air.
The C1~C4 hydrocarbons determined in this section include: methane, ethane, ethylene, acetylene, propane, propylene, n-butane, isobutane, and 1,3-butadiene.
This section recommends but is not limited to the determination of these components. During the specific monitoring, the surrounding environment of the air separation plant should be reasonably analyzed, and the monitoring of other organic components in the air and oxygen that may endanger the safe operation of the air separation plant should be increased.
