A device and method for recuperating a gas turbine engine comprises a compressor [10] being configured to receive a coolant fluid stream, to compress the coolant fluid stream and to discharge the compressed coolant fluid stream to a turbine [14] in fluid communication with the compressor [10]. The compressed coolant fluid stream undergoing thermal exchange within the turbine [14], exit the turbine [14] thereafter. A source of a working fluid stream [44] is in fluid communication with the turbine [14]. The working fluid stream [44] is fluidly isolated from a portion of the coolant fluid stream and undergoing thermodynamic expansion through the turbine [14] to extract energy therefrom. Where desired, the entire coolant fluid stream is fluidly isolated from the working fluid stream [44]. At least a portion of the coolant fluid stream is channeled downstream of the turbine [14] to supply a preheated process fluid stream to another process.
