(54) СПОСОБ АВТОМАТИЧЕСКОГО РЕГУЛИРОВАНИЯ ПРОЦЕССА РЕКТИФИКАЦИИ(54) METHOD FOR AUTOMATIC REGULATION OF RECTIFICATION PROCESS
Изобретение относитс к области автоматического регулировани химических и нефтехимических процессов, в частности к способам автоматического регулировани процесса ректификации .The invention relates to the field of automatic regulation of chemical and petrochemical processes, in particular, to methods of automatic regulation of the rectification process.
Известен способ автоматического регулировани процесса ректификации по авт. св. ЛЬ 460879, согласно которому изменение подачи дистилл та и дополнительного потока продукта на орошение осуществл ют в зависимости от состава целевого продукта.There is a method of automatic regulation of the rectification process according to ed. St. LL 460879, according to which the change in the supply of distillate and additional flow of the product to irrigation is carried out depending on the composition of the target product.
Недостатком известного способа вл етс замедленна реакци системы регулировани ректификационной колонны нри изменении состава сырь , что обуславливаетс инерционностью объекта регулировани при управлении по составу целевого продукта.The disadvantage of the known method is the delayed reaction of the distillation column control system at a change in the composition of the feedstock, which is caused by the inertia of the control object when controlling the composition of the target product.
Целью изобретени вл етс интенсификаци процесса ректификации и стабилизации качества целевого продукта.The aim of the invention is to intensify the process of rectification and stabilize the quality of the target product.
Поставленна цель достигаетс тем, что соотношение компонентов орошени измен ют в зависимости то состава сырь .This goal is achieved by changing the ratio of the components of irrigation depending on the composition of the raw material.
На чертеже представлена схема регулировани процесса ректификации.The drawing shows a diagram of the regulation of the rectification process.
Способ осуществл етс следующим образом .The method is carried out as follows.
На верхнюю тарелку колонны 1 подают дистиллат , отбираемый из сборника орошени 2, и дополнительный компонент орошени , расходы которых регулируют клапанами 3 и 4, установленными соответственно на лини х подачи на орошение дистиллата и дополнительного продукта.A distillate taken from the irrigation collector 2 and an additional irrigation component are supplied to the top plate of the column 1, the costs of which are controlled by valves 3 and 4 installed respectively on the lines for supplying the distillate and the additional product to irrigation.
Клапаны получают управл ющее воздействие от регул тора соотношени 5, который св зан с анализатором 6 состава сырь . Измерение расходов продуктов осуществл ют расходомерами 7, 8.The valves receive a control action from the ratio controller 5, which is associated with the raw material composition analyzer 6. The measurement of product flow rates is carried out by flow meters 7, 8.
Данный способ автоматического регулировани процесса ректификации позвол ет ускорить реакцию системы регулировани колонны при изменении состава сырь , тем самым интенсифицировать процесс и получать целевой продукт стабильного качества.This method of automatic regulation of the rectification process allows us to accelerate the response of the column control system when the composition of the raw materials is changed, thereby intensifying the process and obtaining the target product of stable quality.
