and shall it be vertical/horizontal? where shall I put alcohol in shell or tube? I do have a 110 C temp difference do I have to use a floating head?
any are suitable, depending on rates and the overall equipment. If you plan to do just a stripper, the HX is a reboiler. Typically the heating or cooling medium (if it is clean) is on the shell side. Typically the HX is vertical, but that is often to save space - ought to be flooded, too, so if it's easier to keep it flooded in horizontal, then go that way. You have a lot of options; it's more a function of the overall design and access. How are you going to have a 110° temp difference? this must be pretty sizeable HX for one, and alcohol boils at a low temperature (82° for IPA). You're going to have feed at -30°? That makes no sense. You also wouldn't use steam at 190°C, that would be a terrible waste. All you need is steam at 1 atm (100°C) to effect the stripping.
I don't agree that the cooling or heating medium is on the shell side. Typically these are on the shell side. That is specially true when boiling or evaporating a liquid. You want to have an extra large shell to permit the separation of the vapor from the boiling liquid. In the case of a cooling medium (usually water) you want to be able to clean the heat transfer area and that is easier to do if the cooling medium is on the tube side. As to the floating head. Most of the time the designer would rather build a U-tube bundle if possible in a kettle type design. That eliminates problems with a floating head that can leak and have other problems. This would be a BKU TEMA configuration. It would also be a horizontal design because that best for easy access for maintenance.
