Abstract
Группа изобретений относится к области нефтепереработки, в частности к получению нефтяного кокса замедленным коксованием с содержанием летучих веществ более 15 и менее 25% для использования в качестве коксующей добавки в шихту коксования углей. Способ заключается в том, что исходное сырьё после нагрева подают в выносную секцию ректификационной колонны для смешивания с тяжелым газойлем в качестве рециркулята и формирования вторичного сырья, которое нагревают в реакционно-нагревательной печи и подают в камеру коксования, где образуются коксующая добавка и парожидкостные продукты коксования. Последние фракционируют в ректификационной колонне с образованием газа, бензина, лёгкого и тяжёлого газойлей и кубового остатка коксования. По первому варианту во вторичное сырье перед подачей в камеру коксования добавляют оксид и/или гидроксид кальция в качестве модификатора, который предварительно смешивают с тяжелым газойлем в соотношении (25-35):(65-75). По второму варианту в кубовый остаток добавляют оксид и/или гидроксид кальция в качестве модификатора, предварительно смешанного с тяжелым газойлем в соотношении (25-35):(65-75), после чего кубовый остаток либо смешивают перед подачей в камеру коксования со вторичным сырьем, либо подают непосредственно в камеру коксования. Содержание модификатора, подаваемого в камеру коксования, в обоих вариантах составляет 0,5-10,0 мас.% на исходное сырье.The group of inventions relates to the field of oil refining, in particular to the production of petroleum coke by delayed coking with a volatile content of more than 15 and less than 25% for use as a coking additive in the charge of coking coal. The method consists in that the feedstock after heating is fed to the remote section of the distillation column for mixing with heavy gas oil as recirculate and forming secondary raw materials, which are heated in a reaction-heating furnace and fed into the coking chamber, where coking additive and vapor-liquid products of coking are formed . The latter are fractionated in a distillation column with the formation of gas, gasoline, light and heavy gas oils, and the bottom residue of coking. In the first embodiment, oxide and / or calcium hydroxide are added to the secondary feedstock before being fed into the coking chamber as a modifier, which is pre-mixed with heavy gas oil in the ratio (25-35) :( 65-75). According to the second variant, oxide and / or calcium hydroxide is added to the bottoms as a modifier pre-mixed with heavy gas oil in the ratio (25-35) :( 65-75), after which the bottoms are either mixed before being fed into the coking chamber with secondary raw materials , or served directly into the coking chamber. The content of the modifier supplied to the coking chamber, in both embodiments, is 0.5-10.0 wt.% On the feedstock.
