APPLICATION: WO 2000-US15569 5 Jun 2000. DOCUMENT TYPE: Patent CA Section: 59 (Air Pollution and Industrial Hygiene) Section cross-reference(s): 49 A process for producing chlorine comprises the steps of oxidizing hydrogen chloride in the presence of a catalyst in an oxidn. reactor, passing the product gas together with the catalyst removed from the oxidn. reactor to a high velocity transporter at 150-250° to remove the residual HCl from the product gas, removing the catalyst from the product and recycling the removed catalyst back to the oxidn. reactor. .
