The Ultimate Guide to Fractional Distillation Unit


What is Fractional Distillation?

A process used to purify solvents, additives, natural ingredients, gasoline, biodiesel, crude oil and other materials is Fractional Distillation.

The fractional distillation unit separates different components by their boiling points. The more efficient the column is for distillation, the better the separation.

Fractionation may be performed either in a conventional column for packed distillation or in a column for rotating band distillation.

Heating bath heat and vaporizing the vessel content. Vapors join the column packed and are fractionated. Low boiling liquid vapors join the condenser, are concentrated and deposited into the twin receivers. By breaching the vacuum, the distillate from the final receiver may be extracted.

The package is complete with a spherical reservoir, drain valve, a pocket thermometer, a heating pad, a product cooler, packing column, liquid inlet, coil condenser, and the twin receivers.


The Fractional Distillation Process

The basic steps to the Fractional Distillation Process are as follows:

  • Connect heat to a liquid mixture of two or more principal ingredients, such as a mixture of water and ethanol. 
  • Components with the lower boiling points will begin to vaporize and rise through the column as the liquid heats. Ethanol would first boil off in the water / ethanol example (BP 78 ° C, compared to water (BP 100 ° C). The growing vapor will therefore also contain some of the other substances' molecules. The higher it grows in the tube, the purer the vapor becomes, as heavier molecules condense and becomes liquid again.
  • When vapor rises in the column of distillation, heavier molecules condense back into liquid and "pour" back downwards. Vapor will rise at any given point in a fractionating column, liquid will fall, and molecules will mix. Naturally, columns have such "stages;" a stage is a column region with a certain amount of molecules of each form of material ( i.e., a general percentage of water and ethanol). Columns are constructed by determining the minimum number of necessary stages to be tall enough to achieve a certain percentage separation.
  • Vapor reaching the top of the column (distillate) is gathered through an industrial condenser (a large chiller), which refrigerates the vapor back into a liquid and pipes it into the tank or storage. 
  • The remaining substances in the column continue the distillation cycle, until the desired purity is reached. Some columns are a (most common) continuous cycle, where new base solutions are continuously added. Others are batch systems, where when a desired separation is reached the base is removed. For certain processes the solution is recirculated many times to ensure proper separation of substances.

The basic process of distillation is what's mentioned above. Sometimes in industry a distillation column is called a fractional distillation column. Columns which separate only two substances can be called columns which fractionate. Typically a fractional distillation unit at several points inside the column produces many different products. Mixtures may be pulled at various stages as liquids grow, and get condensed.

An easy example to think about is crude oil distillation, as the How Stuff Works explains. When the crude oil rises in a column, the column pushes out heavy oils lower. Diesel and gasoline climb higher, and are further pushed up the pole. Each of these substances originates from the same "source solution" but includes different percentages of the components contained in the material.

Advantages of Fractional Distillation

  1. Easy implementation:

    One of the greatest advantages of fractional distillation is its easy to use. So long as you are setting up a fully functioning and well-designed program, you should leave it to do the job as it is. You just need to periodically test the device to ensure it works correctly, figure out if it needs upgrades, and fix whatever needs to be fixed. Using microprocessors, modern fractional distillation setups are automated which make the process even easier.

  2. High efficiency:

    Innumerable experiments and actual processes have proven to be effective in fractional distillation. In reality, it's commonly used to produce the goods that modern society needs in many industrial settings. Fractional distillation being highly efficient, particularly for systems using stacked distillation columns which is known to produce more output at lower cost.

  3. Production of Fuel:

    Fractional distillation unit is used to refine crude oil and manufacture diesel, kerosene, gasoline, naphtha and bitumen (used for roofs and roads). Keeping this in mind, it is convenient to infer that fractional distillation has done plenty to advance and modernize human life.

  4. Ability of handling any waste streams:

    Since Fractional Distillation Equipment are customized to the customer's specific specifications, the precise ratios, compounds and concentrations are taken into account to ensure the best possible quality of the finished product. This is capable of recycling the alcohols, solvents, oil & gas, as well as other chemicals and compound combinations.

  5. Flexibility and Compatibility of working with any industry size:

    It is important to know how much waste you generate which would entail recycling while considering a custom-made piece of equipment. Many Fractional Distillation units can work either in a batch (waste is added as produced) or via a continuous (automated) feed method. These can also be built to handle the feed sizes from as low as 1 gallon per hour to as huge as 500 gallons per hour.
