Title:
HYDROGEN CHLORIDE OXIDATION APPARATUS AND HYDROGEN CHLORIDE OXIDATION PROCESS
Document Type and Number:
WIPO Patent Application WO/2007/097408
Kind Code:
A1
Abstract:
Disclosed is a hydrogen chloride oxidation apparatus for producing chlorine by
oxidizing hydrogen chloride through a catalytic gas phase reaction in the presence
of a catalyst by using hydrogen chloride and oxygen as raw materials. This hydrogen
chloride oxidation apparatus is characterized by comprising a mixing portion
for mixing the raw material gases, and a transfer piping for transferring the
mixed raw material gases from the mixing portion to a reactor wherein the catalytic gas
phase reaction is performed. This hydrogen chloride oxidation apparatus is
also characterized in that a gas contact surface of the mixing portion and/or a
part of a gas contact surface of the transfer piping is made of or covered with tantalum
or a tantalum-tungsten alloy. Also disclosed is a hydrogen chloride oxidation
process using such a hydrogen chloride oxidation apparatus.
