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: a saturated hydrocarbon of the paraffin series;one of the heavy ends in a gaseous hydrocarbon mixture.

n pi: the lighter hydrocarbon molecules that comprise gasoline, light kerosene, heptane, natural gas, and so forth.

hydrocarbon liquids with lower boiling points that may flash off when pressure is released.
