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.

Abstract: An apparatus and a process for the production at high capacity of high purity powders from a wire using a combination of plasma torches and induction heating are disclosed. The process has good productivity by providing a preheating system. A mechanism is included in the apparatus, which allows adjusting the position of the plasma torches and their angle of attack with respect to the wire, permitting to control the particle size distribution.
