    Abstract: 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.

    Abstract: A system for generating high pressure steam from dirty water uses a combination of sub-merged plasma arcs and electrical resistive heating. Dirty water from steam assisted gravity drainage, or other dirty water producing process, which needs to be converted into high pressure steam, is fed directly without any pre-treatment, into a plasma fired steam generator, powered by submerged electrodes. The combination of electric arc plasma and resistive heating is created between the submerged electrodes. The heat so generated will boil the water portion of the dirty water feed to generate steam that is collected in a steam space and then removed there from. The solids and other residues (residual sludge) present in the feed water settle down at the bottom of the steam generator and are removed via a blow-down stream. The plasma arcs are used to intermittently remove any scaling or solid deposits that can accumulate on the electrodes.
