Drill-holes let out the hot oil vapors to be condensed.

This cloud of hot oil vapor is too rich to support combustion.

The oil vapor and product gases pass through a hot cyclone for cleaning before sending to a condenser.

One must also prevent oil vapor from entering the regenerator by high-quality purification traps.

The pool was unusable, so foul were the oil vapors.

As this required a generating station, the lamp was changed from oil vapor to a 500W incandescent bulb.

But the wingtanks were not cleaned after the previous cargo of oil, this producing oil vapor.

As a result, the kerogen in the shale decomposes to yield oil vapor and more gas.

The power source was converted to mineral oil in 1882, and to incandescent oil vapor in 1913.

He also worked on illumination systems, notably a lamp designed to burn oil vapour.
