20170210625 · 2017-07-27 ·

A method of continuous hydrothermal carbonization of sludge containing organic matter involves a step of hydrothermal reaction carried out in a reactor, and at least one cooling step in which the sludge having undergone the hydrothermal reaction step is cooled. The hydrothermal reaction step includes: a step of injection of sludge in which the sludge is injected into the reactor by a first inlet; a step of injection of steam in which steam is injected into the reactor by a second inlet, the second inlet being distinct from the first inlet; a step of circulation, in which a mixture consisting of the sludge and the steam injected into the reactor is placed in circulation within the reactor; a step of continuous extraction of at least a portion of the mixture contained in the reactor by a sludge outlet. Also disclosed is a device for carrying out such a method.

Method and system for producing energy from waste

A method and system for the conversion of waste into energy in a sealed system where combustion does not take place and the operating pressure prior to the inlet of the steam or power generating equipment is maintained below atmospheric pressure. Destruction of the RDF (refuse derived fuel) is accomplished by subjecting the RDF to a high temperature environment under controlled conditions in a purpose designed and built reactor. The high temperature environment, <5000 C., is achieved through the use of one or more non-transferred plasma torches for generation of plasma gas. The plasma gas exiting the torch and provides the thermal energy for the continual gasification of metallurgic coke configured as a carbon bed in the lower part of the reactor, which acts as a thermal catalyst and this provides the thermal energy for the gasification process.
