Distillation is a method in chemistry to separate substances from a mixture according to their level of vitality. some examples of distillation are alcohol distillery, distilled water, production of gasoline, paraffin, kerosene etc.
The two most elementary forms of distillation are a continuous http://www.answers.com/topic/equilibrium-flash-vaporization and a simple http://www.answers.com/topic/batch-distillation. In a continuous equilibrium distillation, a continuously flowing liquid feed is heated or reduced in pressure (flashed) so as to cause partial vaporization. The vapor and liquid disengage while flowing through an open drum, and the products emerge as vapor and liquid streams. The vapor product can be condensed to form a liquid distillate. It is also possible to use a vapor feed, subjected to cooling and thereby http://www.answers.com/topic/partial-condensation, again followed by http://www.answers.com/topic/disengagement of the resultant vapor and liquid in an open drum. In a simple batch distillation, an entire batch of liquid is initially charged to a vessel and is then heated, typically by http://www.answers.com/topic/condensation of steam inside a metal http://www.answers.com/topic/coil within the vessel. Vapor is thereby continuously generated, and may be condensed to form a liquid distillate, which is collected. In the batch distillation, increments of vapor are formed in equilibrium with all liquid compositions ranging from the original to the final, whereas the continuous equilibrium distillation gives vapor in equilibrium with only the final liquid composition. Since the distillate consists primarily of the more volatile components and the feed liquid contains more of these substances than does the final liquid, the simple batch distillation gives a more http://www.answers.com/topic/enrichment distillate than does the continuous equilibrium distillation.
The advantages and disadvantages of distillation are quite vast. On advantage of distillation is that the water is pure and will not conduct electricity.
fractional distillation
caustic soda is used to eliminate Mercaptans from hydrocarbons (GPL, Kerosene, ...).it is used also as an injection the desalter (crude distillation unit) to raise PH (reduce corrosion).
Use of water in a refinery is makeup for boiler feed. The chief uses of steam are for stripping, steam distillation, and vacuum distillation. The steam comes in contact with the products in these operations, and generally the steam condensate is so highly contaminated that it cannot be reused for boiler feed or for other purposes. Steam is also used for process heating, for pumping, and, in some refineries, for generating electric power
The key difference between fractional and simple distillation is that fractional distillation is used when the components in the mixture have closer boiling points, while simple distillation is used when the components in the mixture have a large difference in their boiling points
Simple and steam distillation are similar in that they use boiling to separate organic components. Simple distillation boils them off at their boiling points, then condenses them. Steam distillation uses water mixed with the compounds to lower their boiling points and avoid decomposing them by heat.
Whether it is better to use fractional or simple distillation depends on the liquids being separated and on the boiling points of the liquids. When there is a great difference between the boiling points of the liquids, simple distillation may be a better option. Likewise, if there is a small difference in boiling points, then fractional distillation is used.

Crude oil is a complex mixture of hydrocarbons with varying boiling points. Simple distillation can only separate compounds with significantly different boiling points, while the components of crude oil have boiling points that are too close together for effective separation. Fractional distillation, which uses repeated distillation steps, is utilized to separate the components of crude oil effectively.
The basic setup for a simple distillation process includes a distillation flask, a distillation column, a condenser, a receiving flask, and a heat source. The mixture to be separated is heated in the distillation flask, and the vapors rise through the column where they condense in the condenser and are collected in the receiving flask.
You would use simple distillation when the two products you are trying to separate have large difference in boiling points. Fractional distillation is needed when the two products have very close boiling points (like Hexane and toluene). In petroleum refining, the word "fractionation", not "fractional distillation" is used, often interchangeably with "distillation". When we have a crude mixture of different compounds which have very minor difference in their boiling points and cannot be separated simple distillation, then fractional distillation is used. Differenciation of components of petroleum is done by this process
Fictional distillation is a conceptual process used in simulation and modeling to simplify the representation of complex distillation systems, often focusing on key components and behaviors without capturing all physical interactions. In contrast, simple distillation is a physical separation technique that utilizes differences in boiling points to separate components from a liquid mixture through heating and condensing. While fictional distillation aids in understanding and designing systems, simple distillation is an actual laboratory or industrial process.
Simple distillation is used to separate liquids with significantly different boiling points, while fractional distillation is used for liquids with closer boiling points. Vacuum distillation is used at lower pressures to lower the boiling points of substances.
To determine the boiling point using simple distillation, one can heat a liquid mixture in a distillation apparatus and collect the vapor that is produced. The temperature at which the vapor condenses back into a liquid is the boiling point of the substance. This can be measured using a thermometer placed in the distillation apparatus.
Yes.Because simple distillation is a separating of a mixture through heating.it is only applied to separate volatile liquid from the nonvolatile ones.The gas created by the distillation is collected through condensation to form a liquid again.Thank you '_'
The most simple method is distillation.
