PROBLEM TO BE SOLVED: To lower running cost by continuously detoxicating an oily organic chlorine compound in stably reaction conditions and lessening thermal loss. SOLUTION: A mixed liquid of an oily organic chlorine compound and sodium ethoxide is heated and stirred in a primary reaction tank 22 to produce a primary grease-like reaction medium, a hydrothermal solvent is supplied to a secondary reaction tank 42 constituted of a high temperature and high pressure reaction container 54 and an inside reaction cylinder 56 to keep the inside at high temperature and high pressure, the primary reaction medium and a decomposition promotion agent are jetted to the inside of the secondary reaction tank 42 to evaporate the resultant mixture, contact reaction of the hydrothermal solvent, the primary reaction medium, and the decomposition promoting agent is thus carried out to separate sodium chloride and a secondary reaction medium, sodium chloride is scraped by a rotary scraper and discharged by discharging means 66, 68, the secondary reaction medium is cooled by a condenser 96 and separated into a decomposed oil and an alkaline solution by a separation tank 100. Consequently, the oily organic chlorine compound is efficiently detoxicated, the thermal loss is lowered, the energy consumption and the running cost are suppressed, and the load of maintenance and control is lessened. |
