Why put a dryer after the compressor, because that is where the water is.

If you dry the air going into the compressor, you'll have dry air in
the storage tank. The compressor doesn't create water.

If the humidity could be removed before the air was compressed, that would
be true. However, the air dryer, working on compressed air at say
150psi, has 10 times as much air in contact with its cooling fins
as it would with air at atmospheric pressure. These units work more
or less as dehumidfiers. To operate on the input side of a compressor
would just be much less efficient.
