Oil vacuum can refer to a device used to extract oil from equipment for repair, a vacuum chamber for distilling petroleum products, or a fictional device used in a scam. The type of oil vacuum is determined by the context.
An “oil vacuum” can be one of several things, depending on the context in which the term is mentioned. In all cases, the use of this term implies the use of vacuum technology in conjunction with petroleum products to accomplish some sort of desired function.
Several companies make oil vacuums designed to be used to extract oil from equipment so it can be repaired. An example would be an oil change for a car, lawn mower, or similar piece of equipment. Using an oil vacuum cleaner removes as much of the old oil as possible. The vacuum can have a filtration function that allows people to extract the oil, filter it, and then return it when it’s done with service, or it can be designed to pump the oil into a drum for disposal.
Another type of oil vacuum is a vacuum designed for the distillation of petroleum products. In this case, the vacuum is actually a very large chamber that is capable of creating a vacuum, thereby lowering the pressure and reducing the boiling point. When oil is placed in the vacuum chamber, the higher boiling point components vaporize away, allowing for the distillation of various useful components within the crude oil or partially processed oil. This type of oil vacuum is highly specialized equipment that may need to be custom designed for a specific refinery.
The third type of oil vacuum is a fictional device that is employed in a scam. The terms of the scam a lot, but in general, people are welcome to invest in a company that is “developing oil vacuum technology” that will somehow revolutionize the oil industry by extracting normally unrecoverable oil. These systems don’t exist, although some oil companies have actually developed technology designed to increase the amount of recoverable oil in materials such as oil shale and oil sands.
The type of oil vacuum under discussion is usually clear from the context of the conversation. In the case of the first example, oil voids can be seen in repair shops and other facilities where equipment maintenance is handled, and people who work on their own equipment can purchase lightweight models for their own use. In the second case, the oil voids are expensive and complex pieces of refinery equipment, while in the third case, the oil void exists only in the imagination.
