ABSTRACT:
Heat exchange means and method for a continuous wet oxidation apparatus for treating organic waste sewage employing a reactor within which the sewage is treated in the presence of heat, includes handling the influent by means providing a continuous hydraulic circuit for the passage of waste sewage to the reactor, such influent means comprising in series a holding tank communicating downstream with a high pressure pump acting to drive the influent through a low pressure heat exchanger a high pressure heat exchanger and then through an inlet into the reactor, and means for handling effluent from the reactor providing a continuous hydraulic circuit for the passage of treated liquid from the reactor and having in series an outlet and passage from the reactor to conduct hot effluent through the high pressure heat exchanger from which the passage leads to a throttling device and thence to and through the low pressure heat exchanger to a second throttling device and therefrom to a disposal point. The influent waste sewage conducted from the holding tank to the reactor is preheated by heat from the effluent liquid in two stages, comprising a first stage at low pressure and a second stage at high pressure.
