Method for starting up a system for treating waste by hydrothermal oxidation

摘要

A method for starting up a system for oxidating organic bodies. The system includes a tubular body wherein an aqueous body is injected into the inlet thereof at a pressure P 1 the tubular body having a first zone extending the inlet thereof, a second zone into which an oxidating compound can be injected into the output thereof. The inventive method includes the following steps: a first amount of thermal energy Q 1 is provided in the first zone, the amount of thermal energy being able to raise the temperature of the liquid flowing through the tubular body from an initial temperature to a higher temperature T 1 ; and a determined amount of a combustible mixture which can react at the intermediate temperature T 1 in order to provide an amount of thermal energy Q 2 bringing the temperature of the liquid to a reaction temperature T 2 is injected.
