Description
ного режима трубчатой печи пиролиза углеводородов. Углеводородное сырье по трубопроводу 1 поступает в первую конвективн ce fUHro 2 и вторую конвективную секцию 3, где .подогреваетс уход щими дымовыми газами и переходит в радиантную секцию 4, где идет пиролиз углеводородов. Тепло дл реакции пиролиза подаетс через горелки 5, установленные по восемь р дов с каждой стороны. Подача топливного газа на горелки 5 осуществл етс исполнительным механизмом 6 в зависимости о температуры пирогаза на выходе из радиантной секции змее.вика по сигналу датчика 7 температуры. Количество сырь , поступающего в змеевик, регулируетс с помощью регу л тора 8 расхода. Регулирование температуры сырь на входе в радиантную секодию змеевика осуществл ют подачей части неподогретого сырь во вторую конвективную секцию 3 через исполнительный механизм 9 по сигналу от датчика 10 температуры , измер ющего температуру в начале радиантной секции змеевика. Таким образом, регулирование температуры сырь на входе в радмантную секцию змеевика позвол ет оптимизировать врем контакта и соответственно увеличить выход целевого продукта, В таблице приведены результаты хроматографического анализа продуктов пиролиза при реализации предлагаемого способа управлени и при обычном управлении .mode of a tubular furnace for the pyrolysis of hydrocarbons. The hydrocarbon feedstock through pipeline 1 enters the first convective ce fUHro 2 and the second convective section 3, where it is heated by flue gases and goes to the radiant section 4, where the pyrolysis of hydrocarbons takes place. Heat for the pyrolysis reaction is supplied through the burners 5, installed in eight rows on each side. The supply of fuel gas to the burner 5 is carried out by the actuator 6, depending on the pyrogas temperature at the exit from the radiant section of the snake. The amount of raw material entering the coil is controlled by the flow controller 8. The temperature of the raw material at the inlet to the coil's radiant secody is controlled by supplying a portion of the unheated raw material to the second convective section 3 through the actuator 9 according to a signal from the temperature sensor 10, which measures the temperature at the beginning of the coil's radiant section. Thus, controlling the temperature of the raw material at the entrance to the radiant section of the coil allows you to optimize the contact time and accordingly increase the yield of the target product. The table shows the results of chromatographic analysis of pyrolysis products during the implementation of the proposed control method and with conventional control.
