I've never heard of this being called a "Dean-Stark" but it just looks like a fractional distillation incorporating a reflux condenser. You should be able to scale the concept up to the large scale. Fractional distillation is used all the time in brewing.

Yes it can, use a horizontal reflux drum with the distillation column with a weir on it to convert it into a continuous liquid-liquid decanter and return the appropriate stream as reflux to the top of your distillation column.

Yes. I give an industrial example separating water and turpentine here:

Probably. But, it is usually utilized in "batch" type processes.

You can use this system to drive a reaction by removing water, one batch at a time.

I did it once by making a MS Dean Stark apparatus almost of 2 feet hight, on a chemical pulp containg n-butanol and water. It was very impressive for the purpose.
