How do you separate oil from crude oil?
Crude oil IS oil so you don't separate oil from it. You do refine crude oil, separateing parts of it that are used for a variety of purposes. This is usually done by fractional distillation. You heat the crude oil so that the parts with higher boiling points become vapors, the vapors are taken to condensers at different temperatures so materials with different boiling points are condensed into different channels and moved for furhter processing. Portions that do not convert to vapor have very high boiling points and generally are the larger molecules. These "bottoms" hare broken into lighter chemicals in fractionation columns.
Why does distillation work?
The fractional distillation column has the mixture of substance. The mixture consists of substances which have very less difference in their boiling points . When heat is passed, the substance with lowest boiling point forms vapours. After this every substance of the mixture changes into the vapour. These vapours get collected separately and are then condensed to get separate substances
How do you separate mixture of methanol ethyl acetate and water?
This type of mixture is distilled by extractive distillation method. First, methanoic mixture is separated by feeding the required rate of water in the extractor with the counter-current of these two liquids. Later on GC is done for methanol content in the organic layer and if it comes below the required level, it is taken for rectificaton in the column.
Why nitrogen is separated first in fractional distillation?
Nitrogen is separated first in fractional distillation because it has a lower boiling point (-196°C) compared to other gases like oxygen (-183°C) and argon (-186°C). This allows for efficient separation of nitrogen from air at the early stages of the distillation process.
What is the difference between extractive distillation and azeotropic distillation?
Extractive and azeotropic distillation have the common feature that a substance not normally present in the mixture to be separated is deliberately introduced into the system in order to increase the difference in volatility of the most hard to separate components. Extractive distillation can be defined as distillation in the presence of a substance which is relatively non-volatile compared to the components to be separa- ted, and which, therefore, is charged continuously near the top of the fractionating tower, so that an appreciable concentration is maintained on all plates in the tower below its entry. Azeotropic distillation can be defined as distillation in which the add- ed substance forms an azeotrope with one or more of the components in the feed, and by virtue of this are present on most of the plates in the tower above its entry at an These separation methods find their principal applications in the separation of mixtures whose components boil too close together for the economical use of simple fractionating equipment. These separation methods are particularly applicable when the components to be separated differ in chemical type. The theoretical principles in- volved are well documented, and will not be further considered here. The processes differ in the means used to maintain be desired solvent concentration on the plates of the tower. In extractive distillation the high concentration of solvent is maintained by virtue of its non-volatility, and by the fact that it is charged at a high point in the tower. The solvent is, necessarily, removed from the base of the principal tower. In azeotropic distillation, most of the solvent is taken off from overhead, with rela- tively small amounts (ideally, none) drawn off with the bottoms. Extractive distillation is generally more flexible than azeotropic distillation, a greater variety of solvents and a wider range of operation conditions are available; and the concentration of solvent may be controlled by heat and material balances rather than by the accident of azeotrope composition. Furthermore, since vaporization of the solvent is not required beat loads are usually considerably less. It has been mainly used for the separation of toluene, not benzene. But it is mentioned here for the sake of completeness. The use of azeotroptc distillation as a means of separation of BTX components from other non-aromatic hydrocarbons has been known and employed for some thirty years. Acetone is used as an entrainer to purify benzene from similar-boiling non-aro- matic hydrocarbons. Toluene can be separated by the use of either methanol, or of methyl ethyl ketone. Ethyl benzene may be separated from styrene either by isobuta- nol, of by l-nitro-propane. In a 1966 review paper, further information was made available. Fifty-eight pos- sible entraining agents for separating ethyl benzene (bp. 136.20C) and para-xylene (bp. 138.40C) have been examined. It would appear that 2-methyl butanol is the most suceessful agent, requiring a column with only 48 percent of the number of the- oretical plates required if no entrainet were used. The separation of para-and meta-xylenes (bp. 138. 20C and 139. 2aC respectively ) is much more difficult. Of thirty five entrainers examined the best appears to be 2-met- bylbutanol, but the change of relative volatility is only from l. 020 t0 1. 029, and hence it can be safely concluded that azeotropic distillation for the separation of the para-and meta-xylenes is not an economic proposition. Last, and easiest of the C8 aromatics is the separation of meta-from ortho-xylene ( bp. 139. 20C and 144. 50C respectively ). Twenty-eight entrainers were examined, the best being formic acid, required a column containing only 70 percent of the theo- retical plates required of no entrainer is used. Two commercial processes have been developed for the separation of toluene using azeotropic distillation. One using an aqueous solution of methyl ethyl ketone and wa- ter and the other using methanol. Both processes operate on a narrow boiling range concen-
What is the relation between internal and external reflux ratio in distillation column?
The internal reflux ratio is the ratio of the liquid returned as reflux to the distillate product inside the column, while the external reflux ratio is the ratio of the liquid refluxed back to the column to the distillate product taken out of the column. These ratios are related as the sum of the internal and external reflux ratios is equal to the total reflux ratio, which can affect the separation efficiency and energy consumption in a distillation column.
What is the unsupported length of the column?
Length over which the column has no support is taken as unsupported length of the column

How is buchu taken?
Buchu can be prepared as an infusion, a tincture, or in capsules. An essential oil is produced by steam distillation.
How do you determine vapor velocity on a packed batch distillation column having only pot and top composition and can only vary the cooling water flowrate and the voltage to the heaters to change T?
You can determine the vapor velocity in a packed batch distillation column by conducting experimental trials with different cooling water flow rates and heater voltages to change the temperature. Measure the vapor flow rate at the top of the column while varying these parameters and use the ideal gas law to calculate the velocity based on the vapor density and column cross-sectional area. Ensure to account for the composition changes that result from different operational conditions.

What is the name for the process of the separation of 2 liquids?
You can use a sieve if the solid is in the form of large particles. Otherwise filter paper can work nicely. In addition distillation could be used, where the liquid is evaporated and then condensed in another container, thus leaving the solid behind. If the solid is magnetic then a magnet could be used to pull the solid out from the liquid. Some procedures are: - filtering - decantation - crystallization - centrifugation - freeze-drying - evaporation (distillation) and condensation - fluid-bed drying - spray drying
Does distillation work?
Distillation works because different substances have different vapor pressure (volatility). We usually think of distillation as a way to remove water and other substances from alcohol. Alcohol starts as sour MASH. That is some type of grain or other carbohydrate soaking in water. Bacteria or yeast is added to the mixture. The mess smells sour. That is why it is called sour mash. When it is ready, it is taken to the still. In the still, the stuff is heated to the temperature where alcohol evaporates more than water does. The alcohol boils out quicker. It goes down a long cooling tube where the vapor is condensed. It turns back to liquid. There it is placed into a container for storage or use. The rest of the water may be boiled off and the used sour mash might be sold for cattle feed. Thus distillation works because it removes one liquid with a low boiling point from a liquid with a higher boiling point.
