Изобретение относитс к устройствам автоматического регулировани процесса экстрактивной ректификации , Б-частности процесса экстрактивной ректификации при переработке отходов производств винилацетата и его производных и может быть использовано в химической и нефтехимической промьгашенности.The invention relates to devices for the automatic regulation of the process of extractive distillation, B-partly the process of extractive distillation in the processing of waste production of vinyl acetate and its derivatives, and can be used in the chemical and petrochemical industry.
Известно устройство дл автоматического регулировани процессом ректификации, содержащее регул тор температуры, соединенный с клапанами подачи сырь в несколько точек колонны 1.A device for automatic control of the rectification process is known, which contains a temperature controller connected to the feed valves in several points of the column 1.
Наиболее близким по технической сущности к изобретению вл етс устройство дл автоматического регулировани процесса экстрактивной колонны, содержащее датчики расходов сырь , растворител , теплоносител , датчик состава сырь , регул торы расходов растворител и теплоноси-тел , вычислительный, корректирующий , согласующий блоки, динамический фильтр и клапаны подачи растворител и теплоносител 2.The closest in technical essence to the invention is a device for automatic control of the extractive column process, containing sensors for raw material consumption, solvent, coolant, sensor for raw material composition, solvent and heat flow regulators, computational, corrective, matching blocks, dynamic filter and valves supply of solvent and coolant 2.
Однако из-за неустойчивой работы колонны известное устройство не обеспечивает высокого качества продуктов.However, due to the unstable operation of the column, the known device does not provide high quality products.
Цель изобретени - повышение качества продуктов за счет обеспечени устойчивой работы колонны.The purpose of the invention is to improve the quality of products by ensuring the stable operation of the column.
