Oil mist may form when high pressure fuel oil, lubricating oil, hydraulic oil, or other oil is sprayed through a narrow crack, or when leaked oil connects with a high temperature surface, vaporizes, and comes in contact with low air temperature. This happens while the fluids interact with the moving parts during machining. [1]
Oil mist is an atomized amount of oil carried or suspended in a volume of pressurized dry air. The oil mist, actually a ratio of one volume of oil suspended or carried in 200,000 volumes of clean, dry air, moves in a piping system (header). The point of origin is usually a mixing valve (the oil mist generator), connected to this header. Branch ...

Vietnam's oil reserves are in the range of 270–500 million tons. Oil production rose rapidly to 403,300 barrels per day (64,120 m 3 /d) in 2004, but output is believed to have peaked and is expected to decline gradually. In 2003, mining and quarrying accounted for 9.4% of GDP, and the sector employed 0.7% of the workforce.
Mineral oil is organic. However, it is classified as "mineral oil" instead of as "organic oil" because its organic origin is remote (and was unknown at the time of its discovery), and because it is obtained in the vicinity of rocks, underground traps, and sands. Mineral oil also refers to several specific distillates of crude oil. [citation needed]
The Vietnam National Petroleum Corporation was initially created in January 1956 under the name Vietnam National Petroleum Corporation, set up by decree of the minister of commerce.
