Claims (3)

1. Способ получения низкосернистого нефтяного кокса на установке замедленного коксования, включающий приготовление исходного первичного сырья из смеси остатков нефтехимии и/или нефтепереработки и светлой фракции жидких продуктов замедленного коксования, получение вторичного сырья, нагрев последнего в печи до температуры коксования, последующую подачу через узел смешения в реактор коксования с получением кокса и дистиллятных продуктов коксования, отличающийся тем, что вторичное сырье получают в смесителе путем смешения исходного первичного сырья с частью кубового остатка ректификационной колонны - тяжелокипящей фракцией дистиллята коксования при температуре не выше 300°C, а в качестве светлой фракции жидких продуктов замедленного коксования используют смесь легкого и тяжелого газойлей коксования в количестве до 10%.1. A method of producing low-sulfur petroleum coke in a delayed coking unit, comprising preparing the initial primary raw material from a mixture of petrochemical and / or refining residues and the light fraction of the delayed coking liquid products, obtaining secondary raw materials, heating the latter in the furnace to the coking temperature, followed by feeding through the mixing unit in a coking reactor to produce coke and distillate coking products, characterized in that the secondary raw materials are obtained in a mixer by mixing the source between primary raw material with a portion of the bottoms distillation column - tyazhelokipyaschey coker distillate fraction at the temperature not higher than 300 ° C, as well as light fractions delayed coker liquid products, a mixture of light and heavy coker gas oil in an amount up to 10%. 2. Способ по п. 1, отличающийся тем, что часть кубового остатка ректификационной колонны - тяжелокипящей фракции дистиллята коксования подают в узел смешения после печи.2. The method according to p. 1, characterized in that a part of the bottom residue of the distillation column - heavy boiling fraction of coking distillate is fed to the mixing unit after the furnace. 3. Способ по п. 1, отличающийся тем, что в узел смешения после печи подают тяжелую смолу пиролиза.3. The method according to p. 1, characterized in that in the mixing unit after the furnace serves heavy pyrolysis resin.
