FIELD: power industry.
SUBSTANCE: invention refers to the method of controlled recovery of oxidation reaction energy, during which a gas flow is generated, and reaction is performed in oxidation reactor of continuous operation, to which gaseous oxidiser is delivered. Method includes: (a) heating of gas flow to temperature of at least 800°C; (b) direction of gas flow to the stage of internal combustion turbine with open cycle, which is provided with a turbine wheel connected to compressor, which compresses gaseous oxidiser delivered to reactor; (c) control of pressure at turbine stage; (d) support of pressure at turbine stage in the range over minimum value, corresponding to power demand of compressor for compression of gaseous oxidiser delivered to oxidation reactor, and below maximum value determined by the limits of gas turbine by power or pressure by means of gas addition to gas flow; (e) provision of expansion device or auxiliary compressor after gas turbine compressor along the process flow at inlet of gaseous oxidiser to oxidation reactor. Also this invention refers to precursor oxidation method thus obtaining aromatic carboxylic acid or its esters.
EFFECT: using this invention allows effective functioning of turbine.
