A distillation process produces at least ___ output fractions.

One volatile distillate fraction (the ___ fraction), which has boiled and been separately captured as a vapor condensed to a liquid.

One least volatile residue (the ___ fraction) that has not been separately captured as a condensed vapour.

The residue, concentrated in the least volatile components, is removed at the ___ of the column. The distillate, containing the most volatile components, is obtained at the ___.

The reboiler heats the liquid at the bottom of the column, driving the ___ generated up the column.

Any vapour reaching the top of the column (Overheads) is cooled and condensed in the ___.

A proportion of the overheads is returned to the top of the column as ___.

The ___ section removes the less volatile components from the up-flowing vapour – i.e. it enriches the lighter components.

The ___ section removes the lighter components from the residue.

___ distillation refers to the use of distillation in batches, meaning that a mixture is distilled to separate it into its component fractions before the distillation is again charged with more mixture and the process is repeated.

___ distillation, a form of distillation, is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams.

DEMINERALIZATION / DEIONIZATION - Removal of cations (+ ions) and anions (- ions) from water via ion exchange ___.

___ is a natural process in which water flows from low concentration to high concentration through a semi permeable membrane.

___ is a process that uses high pressure to force water from high concentration to low concentration through a semi permeable membrane.

Ultimately, the factors that affect the performance of a Reverse Osmosis System are:

A reverse osmosis membrane is a ___ membrane that allows the passage of water molecules but not the majority of dissolved salts, organics, bacteria and pyrogens.

Desalination is:
