n: C6H6 colourless, volatile, flammable toxic liquid aromatic hydrocarbon used as a solvent and as a motor fuel.

an aromatic (cyclic or ring structure) compound, present in very minor quantities in many crude oils.

the nonvolatile portion of a coating.

a soft coal, intermediate in coal development, containing 15 to 20% volatiles.

natural gas condensate, usually C2 to C8+. The C5-C8 components condense to a very volatile liquid when the temperature decreases near the wellhead.

n: a light hydrocarbon liquid obtained by condensation of hydrocarbon vapours. It consists of varying proportions of butane, propane, pentane, and heavier fractions, with little or no methane or ethane.

the part of the hydrocarbon stream that is a vapor in the formation and condenses to a liquid after being cooled. Normally the volatile condensate has a composition of C5 to C8 and an API gravity of >40.

n: the process of driving off gas or vapor from liquids or solids, usually by heating, and condensing the vapor back to liquid to purify, fractionate, or form new products.

n: Process of first vaporizing a liquid and then condensing the vapor into a liquid (the distillate),leaving behind nonvolatile solid substances of a drilling fluid. The distillate is the water and/or oil content of a fluid.

n: a lightweight covering of either metal or plastic material designed to float on the surface of the liquid in a tank. Alternatively, it may be supported by a float system so that it is just above the free liquid surface. Used to minimise the evaporation of volatile products in a tank.

n: instrument used to distill oil, water, and other volatile materials in a mud to determine oil, water, and total solids contents in volume-percent.

n: an instrument used to distill oil,water and other volatile material in a mud to determin oil, water and total solids contents in volume-percent.

n: a volatile, flammable liquid hydrocarbon distilled from petroleum and used as a solvent or a fuel.

an aromatic solvent with highly-variable quality. Often has a described carbon range in the C7 to C10 area.
