VAPORIZATION OF LIQUID HALOGEN BY CONTACT WITH A PREHEATED GAS

摘要

A method is provided for vaporizing a liquid elemental halogen. A heating gas is preheated in the absence of halogen to a preheat temperature which results in a preheated heating gas. The preheated heating gas is directly contacted with a feed of a liquid elemental halogen and heats the feed to a vaporizing temperature sufficient to vaporize at least a portion of the feed to a quantity of an elemental halogen vapor. A gas mixture results which includes the heating gas and the quantity of the elemental halogen vapor.
