Description
Изобретение относитс к управле™ нию технологическими-процессами и может быть использовано в криогенной техйике.The invention relates to the control of technological processes and can be used in cryogenic technology.
Известен способ регулировани процесса разделени воздуха в криогенной установке путем стабилизации количества исходного сырь , поступающего на разделение, и коррекции количества сырь по качеству и коли- честву продуктов разделени 1.There is a method for regulating the process of air separation in a cryogenic plant by stabilizing the amount of feedstock entering the separation and adjusting the amount of raw materials for the quality and quantity of separation products 1.
Однако осуществление дйнного способа необеспечивает заданные концентрацию и расход газообразного кислорода при одновременном получении жидких продуктов разделени , также дл реализации данного способа в установка разделени воздуха необходимо , примен ть турбокомпрессоры с регулируемой в широких пределах (Производительностью, которые не эффективны и не экономичны в эксплуатации на данных установках.However, the implementation of a single method does not provide the specified concentration and flow of oxygen gas while simultaneously obtaining liquid separation products, it is also necessary to use widely adjustable turbo compressors for the implementation of this method in an air separation unit (Performance that is not efficient and not economical to operate on data installations.
Наиболее близким по технической сущности к изобретению вл етс спсгсоб регулировани процесса разделени воздуха в криогенной установке путем изменени холодопроизводительности детандера рт расхода жидких продуктов разделени в зависимостиThe closest in technical essence to the invention is to regulate the process of air separation in a cryogenic plant by changing the cooling capacity of the expander of the flow rate of the liquid separation products depending
от уровн жидкости в нижней ректификационной колонне при поддержании посто нного уровн в верхней колонне .2 .from the liquid level in the lower distillation column while maintaining a constant level in the upper column .2.
Недостатком данного способа вл етс поддержание посто нного максимального уровн жидкости в разделительных аппаратах при всех режимах, что снижает эффективность работы The disadvantage of this method is to maintain a constant maximum liquid level in the separation apparatus under all modes, which reduces the efficiency of operation.
10 установки в режийе, отличном от режима с минимальной тепловой нагрузкой , и ведет к увеличению энергозат .рат на разделение воздуха.10 installations in a mode different from the regime with a minimum thermal load, and leads to an increase in energy consumption for air separation.
Цель изобретени - уменьшение пр15 херь и .сокращение знергозатрат на разделение воздуха за счет повышени точности регулировани .The purpose of the invention is to reduce the production pressure and reduce the cost of air separation by increasing the control accuracy.
Поставленна цель достигаетс тем, что холодопроизводительность де20 тандера измен ют в зависимости от расхода, газообразных продуктов разделени воздуха, а расход жидких Щ)Одуктов разделени измен ют в зависимости от величины теплового дебалан25 са. При этом, величину теплового дебаланса .определ ют по приращению холодопроизводительности детандера или по разности между количеством вырабатываемого холода и суммарным This goal is achieved by the fact that the cooling capacity of the de Thander varies depending on the flow rate, the gaseous products of the air separation, and the flow rate of the liquid U) of the separation products varies depending on the magnitude of the thermal balance. In this case, the magnitude of the thermal unbalance is determined by the increment in the cooling capacity of the expander or by the difference between the amount of cold produced and the total
