FIELD: treatment plants.
SUBSTANCE: invention relates to systems of cleaning and disinfection of ballast water from biological contaminants on oil and gas sea platforms, ships, oil tankers and can be used in oil industry at development of oil deposits located at Sea shelf. Liquid waste (ballast water) are fed into a container for storage of liquid waste 1. After filling of container 1 through pipelines 10 liquid waste into complex process equipment at disinfection of ballast water by electrochemical method 2. For power supply system of process equipment for disinfection of ballast water by electrochemical process 2 energy is supplied from the accumulator battery unit 7 with the help of electric cables 9. For constant charging of accumulator battery unit 7 is electric energy, which is generated in the installation based on organic Rankine cycle 3 operated from associated gas combustion heat in oil pan 4 transmitted through intermediate circuit 6 with diathermal oil from the boiler 4 to the Rankine unit 3.
EFFECT: technical result-increase of energy and economic efficiency of cleaning liquid waste of oil and gas platforms due to generation of electrical energy using a cheap type of fuel, produced directly on oil and gas platform-associated petroleum gas.
