Description

A system to measure C2+ light hydrocarbons (CnHm, n≧2) in methane-rich gases is reported. Until now, measurement of trace C2+ light hydrocarbons by gas chromatography (GC) has been difficult, because C2+ hydrocarbons could not be separated well from methane. In this system, C2+ hydrocarbon concentration column (stainless hollow pipe) is equipped between GC injection and GC column. With the C2+ hydrocarbon concentration column, only C2+ hydrocarbons are concentrated and methane is removed. After the removal of methane, precise measurement of C2+ hydrocarbons by GC becomes possible.
