United States reserves of residual oil are estimated to be 100 billion barrels.

Therefore his skin didn't give off their residual oils.

In either case, residual oil was seen as a good prospect because it was cheap and readily available.

Fuel oil that contains residual oil left over from distillation.

The problem: the filter contains about a quart of residual oil under pressure, which then overflows.

Special filters are used to clean the air of any residual oil (see "Air purity").

This gets rid of any residual oil.

It was bunker C oil a heavily residual oil which made it more difficult.

Residual oil is oil found in low concentrations naturally or in exhausted oil fields.

A hose can be attached, or if there is room, a container can be placed under the valve to catch the residual oil.

Perchloroethylene is used as a de-greaser to remove residual oil in metal cutting, and as a dry cleaning agent.

The name derives from the brown colouring of the rock forming the cliffs of the headland, caused in part by residual oil deposits.

This cracks the heavy, long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke.

The garment may look clean when you put it away, but after it is stored for some time, the residual oil will oxidize and turn yellow."

Visbreaking unit upgrades heavy residual oils by thermally cracking them into lighter, more valuable reduced viscosity products.

The process thermally cracks the long chain hydrocarbon molecules in the residual oil feed into shorter chain molecules.

The process name of "visbreaker" refers to the fact that the process reduces (i.e., breaks) the viscosity of the residual oil.

Unit 1 & Unit 2 are 800 MW steam electric generating units that use natural gas and low-sulfur residual oil.

The study, in the journal Science, found, for example, that residual oil in stream mouths harmed pink salmon eggs for at least four years after the accident.

At the same time, some of the hot vapors condense into a high-boiling liquid which recycles back into the furnace along with the hot residual oil.

This approach can increase original oil recovery by reducing residual oil saturation by between 7 per cent to 23 per cent additional to primary extraction.

Oils that are used include heavy residual oil (HRO), animal fats, vegetable fats, and synthetic fats.

Often referred to as a gas turbine, a modern combustion turbine operates on a variety of gaseous and liquid fuels ranging from light distillates to residual oil.

"You get less gasoline from the heavier crudes, and more residual oil," said Richard D. Dole, an energy expert at Coopers & Lybrand, the accounting firm.

"If that relief column does not reach the bearing surfaces before the residual oil is burned away," he said, "the engine will suffer not only wear but catastrophic failure.
