FIELD: methods of a pyrolysis of hydrocarbon raw.
SUBSTANCE: the invention is pertaining to the processes of a pyrolysis of hydrocarbon raw with a recycling of the waste condensation moisture and may be used at production of a steam of a dilution from the waste water condensate. Conduct a pyrolysis of hydrocarbon raw. The polluted condensate expose to 3-stage physical and chemical treatment. Purification of the condensate from dispersible impurities is conducted by their settling with the help of mineral coagulants on the basis of hydrolyzed salts of iron and aluminum in a combination with additives of flocculants and alkali. Then the condensation moisture is exposed to adsorption purification from of light hydrocarbons using a direct steam. Conduct afterpurification from the dissolved hydrocarbons by filtrating through active coals. At the stage of production of the steam a steam generator boiler water is added with dozed phosphates with concentration of 0.2-2 mg/l and carry out blowing of the water within the limits of 2-5 %. The technical result of the invention is decreased material inputs, increased efficiency of water purification, averting of a coking up of the equipment.
EFFECT: the invention ensures decreased material inputs, increased efficiency of water purification, averting of a coking up of the equipment.
