Description
СПОСОБ РАЗДЕЛЕНИЯ МНОГОКОМПОНЕНТНЫХ СМЕСЕЙ НА ФРАКЦИИ METHOD FOR SEPARATION OF MULTICOMPONENT MIXTURES IN FRACTION
ОПИСАНИЕ DESCRIPTION
Изобретение относится к способам разделения многокомпонентных смесей, и может быть использовано в пищевой, химической, нефтехимической, фармацевтической отраслях промышленности, а также в других областях техники, где возникает необходимость в разделении многокомпонентных смесей на фракции. The invention relates to methods for the separation of multicomponent mixtures, and can be used in the food, chemical, petrochemical, pharmaceutical industries, as well as in other areas of technology where it becomes necessary to separate multicomponent mixtures into fractions.
Известны способы точного разделения смесей с применением гомотермических дефлегматоров, в которых конденсационное пространство окружено жидкостью или паром с постоянной температурой, поддерживаемой вблизи температуры кипения перегоняемой жидкости. Сюда относятся дефлегматоры (биректификаторы) системы М.Тихвинского для высококипящих смесей и системы Гана, в которых внутреннюю гильзу дефлегматора' наполняют жидкостью с температурой кипения, соответствующей температуре кипения отгоняемой фракции (Техническая энциклопедия, т.6, изд. «Советская энциклопедия», М., 1929, с.576-578). Способ и система Гана, конденсирующие из смеси паров преимущественно низкокипящую фракцию, нашли применение, в частности, в области ректификации сжиженных газов. Данный способ был реализован в ректификационных колоннах системы Клода (Техническая энциклопедия, т.20, изд. «Советская энциклопедия», М 1933, с.742-746, фиг.19-23). Known methods for the exact separation of mixtures using homothermal reflux condensers in which the condensation space is surrounded by liquid or steam with a constant temperature maintained near the boiling point of the distilled liquid. These include dephlegmators (birektifikatory) M.Tihvinskogo system for high-boiling blends and Ghana system in which the inner sleeve dephlegmator 'filled with a liquid having a boiling point corresponding to the boiling point was distilled fraction (Technical Encyclopedia, Volume 6, Ed., "Soviet Encyclopedia", M ., 1929, p. 566-578). The Ghana method and system, condensing mainly a low boiling fraction from a vapor mixture, have found application, in particular, in the field of liquefied gas rectification. This method was implemented in the distillation columns of the Claude system (Technical Encyclopedia, t.20, ed. "Soviet Encyclopedia", M 1933, S. 742-746, Fig.19-23).
Недостатком данного способа является неконтролируемая конденсация паров как нижекипящей, так и вышекипящей фракции на стенках внешнего корпуса, длительное время прогрева жидкости в гильзе парами разделяемой смеси до температуры кипения. The disadvantage of this method is the uncontrolled condensation of vapors of both the lower boiling and higher boiling fractions on the walls of the outer casing, the long time the liquid in the sleeve is heated by the vapor of the mixture to be boiled.
Известен способ перегонки многокомпонентной смеси, включающий ступенчатую регулировку количества выводимой нижекипящей фракции и\или количества тепла, подводимого с греющим теплоносителем в ребойлер таким образом, чтобы температура в контрольном сечении колонны была заданной. В качестве теплоносителя, подаваемого в ребойлер, используют многокомпонентные пары. В процессе перегонки непрерывно анализируют состав исходной смеси. По результату анализа рассчитывают температуру в колонне. По расчетному значению температуры автоматически регулируют давление в сепараторе, установленном на выходе ребойлера для разделения газовой и жидкой фаз теплоносителя (акц. Заявка Японии Ns5068283, B01 D3/42, опубл. «ИСМ», вып.01 , N6, стр. 11 , 1996 год). A known method of distillation of a multicomponent mixture, including stepwise adjustment of the amount of the output boiling fraction and / or the amount of heat supplied with the heating coolant to the reboiler so that the temperature in the control section of the column was set. As the coolant supplied to the reboiler, multicomponent pairs are used. During the distillation process, the composition of the initial mixture is continuously analyzed. According to the result of the analysis, the temperature in the column is calculated. According to the calculated temperature value, the pressure in the separator installed at the outlet of the reboiler for separating the gas and liquid phases of the coolant is automatically adjusted (acc. Japanese application Ns5068283, B01 D3 / 42, publ. "ISM", issue 01, N6, p. 11, 1996 year).
Недостатком способа является его высокая техническая сложность, обусловленная необходимостью непрерывного анализа состава исходной смеси и автоматического
регулирования давления для поддержания требуемой температуры в колонне, а также невозможность практически выделить чистую вышекипящую фракцию. The disadvantage of this method is its high technical complexity, due to the need for continuous analysis of the composition of the initial mixture and automatic pressure control to maintain the required temperature in the column, as well as the inability to practically select a pure higher boiling fraction.
В качестве прототипа выбран способ разделения многокомпонентных жидких смесей на фракции (RU 2465032), включающий нагревание исходного продукта до кипения и последующую конденсацию, отличающийся тем, что пары каждой фракции по мере образования выводят из емкости через соответствующий перепускной клапан и через соединенный с ним штуцер и патрубок направляют в отдельный конденсатор, при этом перепускные клапаны для вывода других фракций оставляют закрытыми. Техническое преимущество данного способа заключается в том, что паровые фазы отдельных фракций выводятся за пределы емкости, в которой нагревается исходный продукт, и направляются в соответствующие конденсаторы, что исключает их смешивание и загрязнение основного продукта примесями. As a prototype, a method for separating multicomponent liquid mixtures into fractions (RU 2465032) was selected, including heating the initial product to boiling and subsequent condensation, characterized in that the vapor of each fraction is removed from the tank through the corresponding bypass valve and through the nozzle connected to it and the nozzle is sent to a separate condenser, while the bypass valves for outputting other fractions are left closed. The technical advantage of this method is that the vapor phases of the individual fractions are removed outside the tank in which the starting product is heated, and sent to the corresponding condensers, which eliminates their mixing and contamination of the main product with impurities.
Способ, выбранный в качестве прототипа, обладает рядом существенных недостатков. В указанном способе невозможно достичь глубокой степени разделения смеси по причине того, что в емкости, в которой нагревается исходный продукт, затруднительно поддерживать постоянную температуру. Это связано с тем, что состав исходного продукта меняется с уменьшением доли легких фракций, и чтобы поддерживать температуру постоянной, необходимо регулировать, а именно - уменьшать,- величину теплового потока. В указанном способе невозможно дискретное, ступенчатое изменение температуры в емкости, в которой нагревается исходный продукт, по этой причине невозможно выделение из исходного продукта узких фракций и отдельных веществ. Также, в, указанном способе невозможно выделение отдельных неконденсируемых газов. The method selected as a prototype has a number of significant disadvantages. In this method, it is impossible to achieve a deep degree of separation of the mixture due to the fact that in the vessel in which the starting product is heated, it is difficult to maintain a constant temperature. This is due to the fact that the composition of the initial product changes with a decrease in the fraction of light fractions, and in order to keep the temperature constant, it is necessary to regulate, namely, reduce, the value of the heat flux. In this method, it is impossible to discrete, stepwise change in temperature in the tank in which the starting product is heated, for this reason it is impossible to isolate from the original product of narrow fractions and individual substances. Also, in the specified method, it is impossible to release individual non-condensable gases.
Задачей изобретения является создание способа и устройства, реализующего способ, который позволил бы в условиях снижения потребляемой энергии обеспечить повышение коэффициента разделения многокомпонентных смесей, более эффективно и интенсивно осуществлять процессы массо- и теплообмена, выделять из смеси отдельные фракции и в предельном случае отдельные вещества, выделять из смеси вышекипящие фракции, в том числе в виде неконденсируемых газов, очищать продуктовый поток от вредных примесей в газовой фазе до его конденсации. The objective of the invention is to provide a method and device that implements a method that would allow under conditions of reduced energy consumption to increase the separation coefficient of multicomponent mixtures, more efficiently and intensively carry out mass and heat transfer processes, separate fractions from the mixture and, in the extreme case, separate substances, separate from the mixture above boiling fractions, including in the form of non-condensable gases, to clear the product stream from harmful impurities in the gas phase before condensation.
Согласно изобретению, при реализации способа интенсификация массо- и теплообмена достигается за счет того, что температура в замкнутом объеме реакционной зоны постоянна и равномерна, а разница температур теплоносителя и разделяемой среды минимальна, для чего замкнутый объем реакционной зоны представляет собой испаритель, в котором циркулирует кипящий теплоноситель в замкнутом контуре с поддерживаемой постоянной температурой.
Согласно изобретению, при реализации способа повышение коэффициента разделения многокомпонентных смесей и выделение узких фракции вплоть до отдельных веществ достигается тем, что в испарителе расположены несколько отдельных замкнутых контуров с различными теплоносителями с разными диапазонами температур кипения при соответствующих давлениях теплоносителей. According to the invention, when implementing the method, the intensification of mass and heat transfer is achieved due to the fact that the temperature in the closed volume of the reaction zone is constant and uniform, and the temperature difference between the heat carrier and the medium to be separated is minimal, for which the closed volume of the reaction zone is an evaporator in which boiling circulates Closed loop coolant with constant temperature. According to the invention, when implementing the method, an increase in the separation coefficient of multicomponent mixtures and separation of narrow fractions up to individual substances is achieved by the fact that several separate closed circuits with different coolants with different ranges of boiling points at the corresponding coolant pressures are located in the evaporator.
Согласно изобретению, при реализации способа возможность выделять из смеси вышекипящие фракции, в том числе в виде неконденсируемых газов, достигается тем, что точно задается давление разделяемой смеси, находящейся в замкнутом объеме реакционной зоны, для чего в патрубке отвода продуктового потока установлен клапан-регулятор давления. According to the invention, when implementing the method, the ability to isolate higher boiling fractions from the mixture, including in the form of non-condensable gases, is achieved by precisely setting the pressure of the mixture to be separated, which is in a closed volume of the reaction zone, for which a pressure control valve is installed in the branch pipe of the product stream .
Согласно изобретению, при реализации способа для очистки продуктового потока от вредных примесей в газовой фазе до его конденсации, узкие фракции или отдельные вещества, содержащие вредные примеси, избирательно выделяют и отводят вовне. According to the invention, when implementing the method for cleaning the product stream from harmful impurities in the gas phase before condensation, narrow fractions or individual substances containing harmful impurities are selectively isolated and removed to the outside.
Согласно изобретению, при реализации способа для очистки продуктового потока от оставшихся вредных примесей, поток, следующий в газовой фазе в конденсатор направляют в эжектор, где к нему подмешивают абсорбент, проводят смешение и взаимодействие потока и абсорбента, прореагировавший с вредными примесями абсорбент отделяют, отводят в регенератор, проводят регенерацию абсорбента, и снова направляют на эжектирование, продуктовый поток конденсируют, отводят вовне. According to the invention, when implementing the method for cleaning the product stream from the remaining harmful impurities, the stream following in the gas phase is sent to the condenser into the ejector, where absorbent is mixed with it, mixing and interaction of the stream and absorbent are carried out, the absorbent reacted with harmful impurities is separated, taken into regenerator, carry out the regeneration of the absorbent, and again sent for ejection, the product stream is condensed, taken out.
Отличительной особенностью способа является то, что давление в конденсаторе в точности равно атмосферному, что достигается, например, с помощью установленной в конденсаторе гибкой мембраны, воспринимающей давление атмосферы. A distinctive feature of the method is that the pressure in the condenser is exactly equal to atmospheric, which is achieved, for example, by means of a flexible membrane installed in the capacitor that senses the atmospheric pressure.
