Steam plasma arc hydrolysis of ozone depleting substances

摘要

A two step process for the destruction of a precursor material using a steam plasma in a three zone reactor wherein the precursor material is hydrolyzed as a first step in the high temperature zone of the reactor, followed by a second step of medium temperature oxidation of the reactant stream in the combustion zone of the reactor where combustion oxygen or air is injected and immediate quenching of the resulting gas stream to avoid the formation of unwanted by-products. A related apparatus includes a non transferred direct current steam plasma torch, an externally cooled three zone steam plasma reactor means for introducing the precursor material into the plasma plume of the plasma torch, means for introducing the combustion air or oxygen into the combustion zone, means for exiting the reactant mixture from the reactor and means for quenching the reactant mixture located at the exit end of the reactor.

1. An apparatus for carrying out a two step process for the destruction of a precursor material using a reactor, wherein the precursor material is hydrolyzed as a first step in a high temperature zone of the reactor, followed by a second step of medium temperature oxidation of the reactant stream in a combustion zone of the reactor where combustion oxygen or air is injected and immediate quenching of the resulting gas stream to avoid the formation of unwanted by-products, the apparatus comprising:
the reactor having three zones, means for introducing the precursor material in the form of gas vortex or fine liquid spray or solid particles into the reactor, means for introducing the combustion air or oxygen into a combustion zone of the reactor, means for exiting the reactant mixture from the reactor and means for quenching the reactant mixture located at the exit end of the reactor.
