Overview
Compressor oils are lubricants used in mechanical devices where the purpose is to reduce the volume and increase the pressure of gases for use in a variety of applications. This document gives general guidance for the sampling and gas chromatographic analysis of compressor oil in biomethane or compressed natural gas (compressed gas p > 18 MPa). The compressor oil mass fraction is determined by sampling on coalescing filters under defined operational conditions (the two first cubic meters of gas referring to standard conditions, delivered at a refuelling station). The compressor oil content is expressed as mass fraction. The scope of this method is from 3 mg/kg - 30 mg/kg. The responsible national standardization committee is Working Committee NA 032-03-08 AA "Biogas" ("Biogas") at DIN Standards Committee Gas Technology (NAGas).
