Abstract

A method of dehalogenating a particulate composition in a calciner having a heating zone and a cooling zone is presented in which a dehalogenating atmosphere flows through the calciner, including a constricted zone in the calciner, countercurrent to the movement of the composition through the calciner. The constricted zone is formed by positioning a baffle means in the calciner and the baffle means in one embodiment is preferably positioned in the cooling zone of the calciner with a face of the baffle means being located near, and preferably approximately at, the junction of the heating zone with the cooling zone. The flow of the dehalogenating atmosphere through the constricted zone substantially minimizes diffusion into the cooling zone of the gaseous impurities removed from the particulate compounds in the heating zone. Various embodiments of a baffle means and mounting means for positioning the baffle means in a calciner are also presented.
