Abstract: The invention relates to a method and apparatus for recovering power from the gaseous stream produced by an oxidation reaction. Specifically, the invention is based on heating the gaseous stream from the oxidation reaction to a temperature of at least 800 °C and recovering energy through a gas turbine. The compressor stage of the gas turbine compresses the oxidant feed to the reactor thereby at least partially offsetting the cost of providing the high temperature and pressure reaction conditions in the reactor. The invention also provides improved control of the power recovery system by optimising the efficiency of the gas turbine by feeding gas to the gaseous stream to modulate the flow of gas to the turbine relative to the compressor discharge flow in order to compensate for the consumption of oxidant in the reactor.

Abstract: La invención se refiere a un método y aparato para recuperar energía de la corriente gaseosa producida por una reacción de oxidación. De manera específica, la invención se basa en el calentamiento de la corriente gaseosa de la reacción de oxidación a una temperatura de al menos 800°C y recuperar la energía a través de una turbina de gas. La etapa de compresor de la turbina de gas comprime el oxidante alimentado al reactor por lo que compensa al menos parcialmente el costo de proporcionar las condiciones de reacción de alta temperatura y de alta presión en el reactor. La invención también proporciona control mejorado del sistema de recuperación de energía al optimizar la eficiencia de la turbina de gas al alimentar gas a la corriente gaseosa para modular el flujo de gas a la turbina con relación al flujo de descarga del compresor a fin de compensar el consumo de oxidante en el reactor.
