Abstract
1. Способ получения коксующей добавки замедленным коксованием, включающий нагрев исходного сырья, смешивание исходного сырья с рециркулятом в емкости с формированием вторичного сырья, нагрев вторичного сырья и подачу его в камеру коксования, коксование с образованием целевого продукта и дистиллятных продуктов, которые подают в ректификационную колонну для разделения на газ, бензин, легкий и тяжелый газойли коксования и кубовый остаток, отличающийся тем, что нагрев вторичного сырья осуществляют до температуры 455-485°C, причем для различных видов исходного сырья предварительно экспериментально устанавливают зависимость содержания летучих веществ в средней пробе коксующей добавки от температуры вторичного сырья на входе в камеру коксования, затем в зависимости от плотности исходного сырья по установленной графической зависимости подбирают температуру вторичного сырья на входе в камеру коксования.2. Способ по п.1, отличающийся тем, что в качестве рециркулята используют тяжелый газойль коксования, при этом коэффициент рециркуляции составляет не более 1,2.3. Способ по п.1, отличающийся тем, что кубовый остаток подают в камеру коксования либо непосредственно в камеру коксования либо - в смеси со вторичным сырьем.4. Способ получения коксующей добавки замедленным коксованием, включающий нагрев исходного сырья, подачу нагретого исходного сырья в нижнюю часть ректификационной колонны для смешивания исходного сырья с высококипящими фракциями продуктов коксования с образованием вторичного сырья, а также газа, бензина, легкого и тяжелого газойлей коксования, нагрев вторичного сырья и подачу его в камеру коксования,1. A method of producing a coking additive by delayed coking, including heating the feedstock, mixing the feedstock with recycle in a container to form secondary feedstock, heating the secondary feedstock and feeding it into the coking chamber, coking with the formation of the target product and distillate products that are fed to the distillation column for separation into gas, gasoline, light and heavy coking gas oils and bottoms, characterized in that the secondary raw materials are heated to a temperature of 455-485 ° C, and for different feedstocks previously experimentally establish the dependence of the volatile substances in the sample medium coking additives from the secondary feed temperature at the inlet of the coking chamber, then depending on the density of the feedstock installed graphics selected according recycled inlet temperature koksovaniya.2 chamber. The method according to claim 1, characterized in that a heavy coking gas oil is used as a recirculate, wherein the recirculation coefficient is not more than 1.2.3. The method according to claim 1, characterized in that the bottom residue is fed into the coking chamber either directly into the coking chamber or in a mixture with secondary raw materials. A method of producing a coking additive by delayed coking, including heating the feedstock, supplying heated feedstock to the bottom of the distillation column to mix the feedstock with high boiling fractions of coking products to form secondary feedstock, as well as gas, gasoline, light and heavy coking gas oil, heating the secondary feedstock and feeding it into the coking chamber,
