ABSTRACT:
A hydrocarbon conversion apparatus is dried as a preliminary step of a startup procedure by the circulation of a superheated vapor stream which is formed in one of two reboilers attached to a fractionation column used in the process. Preferably this vapor stream is formed on the tube side of the reboiler, with normal on-stream operation comprising the generation of the vapors fed to the column on the shell side of the reboiler.
