METHOD FOR THE NEUTRALIZATION OF WATER WASTE CONTAINING HYDROCARBONS Russian patent published in 2022 - IPC C02F1/72 C02F101/32 

FIELD: chemical technology.

SUBSTANCE: method relates to the field of chemical technology, namely to methods for the disposal of industrial water waste of a wide range. The method for neutralization of water waste containing hydrocarbons includes compressing industrial water waste with a pump and supplying it to a heat exchanger at a pressure above the critical one for clean water. The compressed oxidant is supplied to the heat exchanger by means of a compressor at a pressure above the critical pressure for pure water. In continuous mode, waste and oxidant are mixed and preheated to a temperature of 250-350°C in a heat exchanger. In a continuous mode, a mixture of waste and an oxidizer is fed from a heat exchanger into a reactor with induction heating, and the oxidation process is carried out in a supercritical water medium at a temperature above the critical temperature for pure water. Purified water is discharged continuously. As it accumulates, inorganic components precipitated to the bottom of the reactor are removed.

EFFECT: increased efficiency of neutralization of water wastes containing hydrocarbons.
