Supercritical oxidation system using a cooled-wall shell

Supercritical oxidation system using a cooled-wall shell Provides low cost reactors 8 for high pressure oxidation systems because it is not necessary for the pressurized shell 15 to withstand the oxidizing environment and because the shell 15 is at a lower temperature than the oxidation process. For this the said shell 15 is cooled internally by its own feed 1 from the system or by a fluid which is external to the process, and therefore requires less thickness, the cooling in both cases having a pressure similar to that of the oxidation. The oxidation takes place within a reaction chamber 17 which does not require great mechanical strength because its walls are at similar internal and external pressures, the said chamber 17 being within the reactor 8. Within the reactor 8 there is also an internal heat exchanger 16 which increases the energy efficiency of the system. SISTEMA DE OXIDACION SUPERCRITICA MEDIANTE CARCASA DE PARED REFRIGERADA. PROPORCIONA, PARA PROCESOS DE OXIDACION A PRESION ELEVADA, UNOS REACTORES (8) DE MENOR COSTE POR NO SER NECESARIO QUE SU CARCASA PRESURIZADA (15) SOPORTE EL AMBIENTE DE OXIDACION Y POR ENCONTRARSE ESTA CARCASA (15) A MENOR TEMPERATURA QUE LA DEL PROCESO DE OXIDACION. PARA ELLO, DICHA CARCASA (15) ESTA REFRIGERADA INTERIORMENTE, REQUIRIENDO ASI MENOR ESPESOR, MEDIANTE LA PROPIA ALIMENTACION (1) DEL SISTEMA O MEDIANTE UN FLUIDO AJENO AL PROCESO; PRESENTANDO EN AMBOS CASOS DICHA REFRIGERACION UNA PRESION SIMILAR A LA DE OXIDACION. LA OXIDACION SE PRODUCE DENTRO DE UNA CAMARA DE REACCION (17) QUE NO REQUIERE GRAN RESISTENCIA MECANICA POR ENCONTRARSE SUS PAREDES A UNAS PRESIONES INTERNAS Y EXTERNAS SIMILARES, AL ESTAR DICHA CAMARA (17) EN EL INTERIOR DEL REACTOR (8). DENTRO DEL REACTOR (8) HAY ADEMAS UN INTERCAMBIADOR DE CALOR INTERNO (16) QUE AUMENTA EL RENDIMIENTO ENERGETICO DEL SISTEMA.
