What is the cloud?
oil is predominantly composed of various hydrocarbons in gas, liquids or in solid states. Members of this group are oil and natural gas. One hydrocarbon in oil is paraffin, which is commonly known in food preservation. During the refining process, different temperatures provide different products and the temperature at which the wax begins to appear in fuel or oil, is called a cloud.
raw oil in its natural state is relatively unnecessary. Distillation in the refining process creates a more usable product. Different methods using changes in heat and pressure are used to achieve the desired result. The refinery contains different units such as Coker, cracking and alkylation that produces the levels of practical goods. Some commonly known examples are diesel, petrol, kerosene, gasoline, butane, heating oil, lubricating oil and industrial fuel.
refineries uses all its sources, including heat and air, when oil distillation.Surovina transforms into a gradually more polished product. Even some led someMore products are useful when further refined. The asphalt used in the construction of roads and oil coke, used in the production of dry cells or electrodes, are several examples.
Each of these products has its own cloud. A specific temperature in which this fuel or oil begins to retract from the appearance of the wax crystals. During the process, it is important that the refiner knows what this temperature is for each product. These wax particles can cause damage if they are left in fuel designed for internal combustion engines such as gasoline.
wax that appears in cloud point can be harmful and destructive if it is not discovered in refined fuels. Fuel -fuel filters and fuel injection systems can be clogged from the accumulation of wax. Even in the refinery itself, it may be harassment to Hromlating and blocking pipes and other pieces of equipment that work at temperaturests the cloud point.
American Society for Testing and Materials (ASTM) provides an outline of test objectives to determine the cloud point. Standardized testing allows agreement with the uniformity for those who offer test methods, as well as for refineries that use them. In general, cloud points for all fuel and oil levels are analyzed in transparent layers that are 40 mm thick.
Methods for finding a cloud point vary. Constant cooling speed is one standard method used to determine the cloud point in pure and mixed fuels and oils. This method cools the liquid at a stable speed, such as two stages per minute, which makes it easier to determine the exact temperature at which wax crystals are formed, giving the exact point of the cloud.
