Reactor evacuation method and system for dehydrogenation reactor

Abstract

The present disclosure provides a method for evacuating a high temperature reactor requiring vacuum pressure during one or more steps of the reaction process, including directing a reduction gas stream from the reactor to a quench system in fluid communication with the reactor, the quench system comprising one or more enclosures wherein the reduction gas stream directly contacts a liquid cooling medium, wherein the liquid cooling medium is water; withdrawing a cooled gas stream from the quench system; and directing the cooled gas stream to a vacuum pump in fluid communication with the quench system and the reactor to reduce the pressure within the reactor to a vacuum pressure. A system for evacuating a high temperature reactor is also provided, including a high temperature reactor combined with a quench system and a vacuum pump as described above.
