Rectifier:
rec·ti·fi·er –noun
1. a person or thing that rectifies.
2. Electricity. an apparatus in which current flows more readily in one direction than the other, for changing an alternating current into a direct current.
3. the apparatus that in distillation separates the most volatile material by condensing it; condenser.

A rectifier converts alternating current to direct current, i.e. the negative part is rectified to become non-negative. An example of a rectifier is a diode.

If you have a sinusoidal ac signal a rectifier can limit the peak values of that particular signal in order to come up with a "flatter" output or a lesser value (or whatever). The main function of a rectifier is to aid in producing a dc (direct current) output from an ac (sinusoidal) input. A good example for this is your mobile phone charger in which it converts 220V ac to 12V dc (for example) in order to charge the battery of your mobile phone.

In the 1880's there was a war of currents between Edison and Tesla over the advantages and disadvantages of a.c and D.C current for power distribution. A.C eventually won the day and a.c is now the standard. But D.C under Edison was very popular then and was considered the 'correct' one to use.
However there is a hangover from that time. As there was so much rivalry over the 2 types of currents at that time, a.c. current is still to this day required to be 'rectified'...or 'repaired' to make it better ...if you will....into D.C as a.c was deemed unsuitable in those days.
So you can see that even now when we make a.c. into D.C....we are rectifying the 'faulty' a.c. current.
As an aside to this issue, the standard notation for the 2 currents is lower case for a.c and UPPER CASE for D.C....D.C is still considered the better one....
A good question...we commonly refer to a diode as a Rectifier.

It's an elecytrical circuit that takes an alternating current and turns it into a direct current.

A rectifier is a circuit that removes the spikes in the input voltage. Hence the name rectifier.Hope this helps..let me know

If you're talking about distillation, it's the bottom half of the column (well, the part under the inlet anyway). The purpose of this section is to remove any traces of the light component from the bottoms stream.
