Plasma torches which use steam as the main plasma forming gas produce a plasma plume with a high concentration of H+ and OH− ions. The steam plasma plume rich in these chemically very reactive species can be used in a wide range of applications starting from coal gasification to hazardous waste treatment [see references 1 to 4 detailed hereinbelow]. Steam plasma torches have been very successful in achieving difficult chemical conversion particularly for the destruction of chlorinated and/or fluorinated hydrocarbons Long and Strong in PyroGenesis!
