What's The Difference Between The Seperation Columns?

I do confuse between the right difference:
Distillation Column:
Simple distillation is generally used when the boiling points are significantly different.
Fractionator:
Fractional distillation is used when the boiling points of chemicals in a mixture are close to each-other,
Splitter
To split the product into 2 sreams (1- Light Product)
(2- Heavy Product)
Stabilizer:
To stabilize the product
Stripper:
Steam is injected to be as stripping material to strip to different streams
Could do you give me the right difference, please?
Regards

The term stabilizer is usually used when the purpose is to remove light ends such that the bottoms product is "stable", i.e. it can be stored in an atmospheric tank.
The term stripper is usually used when the purpose is to remove light ends that are undesirable in the bottoms product for other reasons, such as removing H2S from gasoline. Many times, strippers and stabilizers are doing the same job. I've had some say strippers are "stripped with steam or another gas" while stabilizers are reboiled, but many refinery columns are installed with "reboiled side strippers" so that definition doesn't really work.
A splitter is usually a simple distillation column that makes a top and bottom product, whereby the feed has been "split" into two streams. These can be complex mixtures (e.g. a naphtha splitter making light and heavy naphtha) or simple mixtures (e.g. a C3 splitter separating propene from propane).

These are all generally specific names for versions of "distillation columns". Chemical plants often use the term "distillation column" more frequently, while oil refineries use the term "fractionation column". The term distillation is often used when pure components are being separated, while fractionation is used when the product streams are complex mixtures that are "fractions" of the feed.

am very much interested in this stripper and stabilizer are they separation techniques or materials for separating light ends
how are they done or constructed
tell me more i have been cracking used motor oil for diesel fuel and my diesel condensate comes with a darker color and a bad smell and am looking for ways to get a cleaner and smell free diesel fuel

1. For removing color and smell, I believe activated carbon filter would be the right process.
2. Stripper or stabilizer remove the light ends (that may include the gas causing the smell) but the color is normally caused by heavy ends components.
3.I suggest that you install a sand filter followed by an activated carbon filter,

i have tried activated charcoal but my condensate still comes with excess dark color
but i will try using it together with the sand filter
thanks

1. You need to use a good quality activated carbon. Poor quality charcoal may contribute to the black color.
2. Take sample of fluid after the charcoal treatment and filter using fine filter paper, if the fluid becomes clearer, this indicates that the color could be due to carbon particles.
3, Sand filter can remove suspended particles.
