Determining the content of oil vapor in compressed gases

Compressed gas at the exit of compressors contains mineral oils in the form of vapors and extremely fine particles forming an oily spray or a finely dispersed aerosol. When working out the specifications for cleaning the compressed gas, its oil content in the form of aerosol and as vapors should be known. This paper presents a method worked out at the ''Energokhimmash'' Special Designs Bureau for determining the content of oil vapors and the concentration of oil aerosol in gases at the exit of different types of compressors.
