n: a test for the composition of gas or two-phase gascondensate streams. The analysis generally shows not only the composition in percentage of each hydrocarbon present through hexanes or heptanes but also the gallons per thousand cubic feet of liquids by component and the heating value of the gas.

n pi: 1. the parts of a hydrocarbon mixture that have the highest boiling point and the highest viscosity (such as fuel oils and waxes). 2. hexanes and heptanes in a natural gas stream.

n: C2H14 a liquid hydrocarbon of the paraffin series.

n: the saturated hydrocarbon compounds of the general formula Cn2n (e.g., ethene or ethylene, C2"4). They are cycloparaffin derivatives of cyclopentane (CS"IO) or cyclohexane (C6"12) found in crude petroleum.
