Transurethral resection of the prostate (TURP) is generally a safe procedure. However, as with all types of surgery, it is associated with potential risks. The main risks are described below.
The petrol crude is a mixture of many different types of hydrocarbons mixed together. The process of fractional distillation is used to separate these different ingredients of petroleum crude during the manufacture of petrol and other fuels derived from petroleum crude.he refining is done by separating all the different fuels and chemicals by fractional distillation in an oil refinery. Fractional distillation involves heating the crude petroleum, so that at different temperatures the different fuels and chemicals will vaporise and be collected in a pure state.
Fractional distillation. This is good for separating two or more liquids from each other. For example, ethanol (alcohol) can be separated from a mixture of ethanol and water by fractional distillation. This method works because the two liquids have different boiling points.vaporation. This is good for separating a soluble solid from a liquid (a soluble substance does dissolve, to form a solution). For example copper sulphate crystals can be separated from copper sulphate solution using evaporation.
