Background technique
Fields, the application ranges such as the commonly used petroleum of instrument air, chemical industry, automobile, metallurgy are very extensive.Main function is
For pneumatic actuator, positive draft device provides gas source, guarantees the trouble-free operation of equipment and process flow.
A small amount of vapor is only allowed to exist in instrument air, if once these vapor cryogenic condensations (condensing), meeting
So that pipeline and instrument is got rusty, reduces instrumentation reliability, can also jeopardize control system when serious.Therefore, in instrument air
The control of moisture content should be not condense as principle.Close dew temperature limit requirements, should be according to air supply system working environment minimum temperature
Depending on.SH/T 3020-2013 " petrochemical industry instrument supplies design specification " regulation instrument air is under operation (online) pressure
Dew point, should be 10 DEG C at least lower than device location history last year (season) extreme minimum temperature, that is to say, that purified dry gas
Dew point should be 10 DEG C lower than environment temperature lower limit value.There are many drying means of gas, and there are commonly chemical method, Mechanical Method and absorption methods
Deng the method for being adsorbed by drying being mostly used at present, but the conventional method pressure leak source that is adsorbed by drying is generally -10 DEG C, it cannot be guaranteed that high and cold
The normal use in area is easy to produce ice and blocks up phenomenon, influences equipment normal operation, and need to regularly replace adsorbent.
Presence of the oil content in instrument air is very serious on the influence of the normal operation of instrument.In control instrument gas source
Oil content mainly from air compressor machine lubricating oil, so, to reduce the oil content content in gas source, also very using efficient oil removing apparatus
It is necessary.General provision oil content should control 8ppm (W) below.
