ABSTRACT:
An apparatus process is provided for the destruction of a toxic organic chlorine-containing compound, especially, a chlorine- and arsenic-containing compound. The apparatus includes a main reactor into which is introduced the chlorine-containing compound, e.g., a Lewisite as a mustard gas, an oxidizing agent and a pH controlling agent, the main reactor including a hot heat exchanger and a cold heat exchanger, a source of inert blanketing gas to provide an oxidation product of the organic original chlorine-containing compound. Preferably, after completion of the oxidizing reaction, any residual oxidizing agent is catalytically decomposed. Then, the oxidation product of the original organic chlorine-containing compound, is preferably decomposed in a catalyst containing vessel at an alkaline pH, e.g., to a maximum final pH of about 11 in a liquid knockout vessel which includes a lower liquid discharge and an upper gaseous discharge connected to a vented absorber vessel to provide an inorganic compound, e.g. an inorganic arsenic-containing-compound. Such compound can easily and safely be disposed of.
