Falling Film Evaporator

An apparatus and method are disclosed for controlling the thickness of a flowing, laminar fluid film. The film flow may be gravity-induced or the result of an alternative force. The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. For example, in some applications, it may be desirable to maintain an approximately constant film thickness as the fluid flows over the active region of the surface. The geometry of the flow surface is used to obtain the desired control over the fluid film thickness. The flow surface is the outer surface of a solid with a closed upper end and a lower end that may be open or closed. An open lower end allows for injection of a heated material, which may be used to heat the solid surface. This process may be used to heat the fluid flow surface so that evaporation of the flowing fluid results. A falling film evaporator is one application of the disclosed invention. A carbon capture system using a thin, flowing algae film is another application. Other potential uses of the invention are disclosed as well.

Employing bottoms of a second fractionator as a refrigerant medium for first fractionator overhead

Control apparatus for fractionation tower

Our novel control apparatus optimizes the operation of a fractionation tower. A feed varying in composition flows into the tower at an uncontrolled, varying rate. This feed is distilled so that a portion of the feed is withdrawn from the tower as distillate and another portion is withdrawn from the tower as bottoms. A part of the distillate is returned to the top of the tower as reflux. The control apparatus includes a reflux controller for automatically controlling the rate at which reflux is returned to the tower, a pressure controller for automatically controlling the pressure within the tower, a distillate controller for automatically controlling the rate at which distillate is withdrawn from the tower, and a bottoms controller for automatically controlling the rate at which bottoms are withdrawn from the tower. As the feed flow rate and feed composition change, distillate and bottoms flow rates are changed in proportion to these changes in feed. A divider circuit, responding to the feed flow rate and feed composition changes, controls the distillate and bottoms flow controllers so that the distillate and bottoms flow rates and the ratio between these flow rates are such that product specifications are maintained despite variations in the feed flow rate and feed composition. An override circuit, responding to fluctuations in the liquid level in the tower, controls the material balance within the tower. When the liquid level is in danger of exceeding predetermined level limits, the override circuit terminates control of the bottoms controller by the divider circuit and controls the bottoms controller as a function of the liquid level until the liquid level is no longer in danger of exceeding the predetermined level limits. The control apparatus includes means calibrated to maintain the bottoms flow rate such that the liquid level is within the level limits, and calibration means which calibrate said calibrated means whenever the override circuit terminates the ...

Apparatus and method for purifying a liquid

For purifying a liquid, the liquid is caused to evaporate in a cyclone in a recirculation circuit. Vapor is discharged via a discharge channel in which a compressor is included. In a heat exchanger downstream of the compressor, supplied vapor condenses and heat thereby released is transferred to liquid in the recirculation circuit. A liquid inlet of the cyclone is placed and directed for delivering a jet having a directional component tangential with respect to an inner surface of the cyclone. The liquid inlet has a section shaped such that in operation the delivered jet is a flat jet having a cross section which in a direction parallel to a nearest generatrix of the inner surface of the cyclone is greater than in a direction perpendicular thereto. The jet contacts the inner surface of the cyclone before drop formation occurs in the jet. A method for purifying a liquid is also described.

Method of separating mixture of different saturation degree c4-hydrocarbons

A process for separating, by means of a selective solvent, a mixture of C4-hydrocarbons which contains some hydrocarbons which are more soluble in the selective solvent and some which are less soluble therein, in which process the hydrocarbon mixture is separated, in an extractive distillation zone, into a top product which contains the less soluble hydrocarbons and an extract which contains the more soluble hydrocarbons and the selective solvent, the extract, taken off as the bottom product, is subjected to a flash evaporation and the resulting vapor component of the extract is recycled to the extractive distillation zone while the liquid phase remaining after the flash evaporation is fed to a solvent recovery zone, in which the liquid phase obtained from the flash evaporation is separated into a product containing the hydrocarbons and, as the bottom product, the selective solvent which has been freed from the hydrocarbons, the resulting selective solvent is recycled to the extractive distillation zone and the product which is obtained from the solvent recovery zone and contains the hydrocarbons is partially or completely recycled to the extractive distillation zone, after increasing the pressure in a compression zone, in which process the extract taken off the extractive distillation zone is brought, prior to the flash evaporation to a higher pressure than the pressure in the extractive distillation zone and thereafter the extract which is under this higher pressure is heated, in a heat exchange zone, by indirect heat exchange with the selective solvent obtained as the bottom product from the solvent recovery zone, and the heated extract is subsequently let down, in the flash evaporation, to a pressure which is at least equal to the pressure in the extractive distillation zone and is higher than the pressure in the solvent recovery zone.

Способ получения неочищенного 1,3-бутадиена

Описан способ получения неочищенного 1,3-бутадиена при помощи экстрактивной дистилляции из С 4 -фракции, содержащей С 4 -ацетилены в качестве вторичных компонентов, с использованием селективного растворителя. Способ осуществляют в колонне с разделительной перегородкой, содержащей в донной части испаритель, в которой в продольном направлении установлена разделительная перегородка, образующая первую зону, вторую зону и нижележащую объединенную зону колонны, соединенную по верхнему потоку с экстрактивной промывочной колонной. Подвод энергии к колонне с разделительной перегородкой через нижний испаритель регулируют так, что из колонны с разделительной перегородкой отводят нижний поток, содержащий растворитель, насыщенный С 4 -ацетиленами, в котором доля 1,3-бутадиена ограничена с таким расчетом, что потери 1,3-бутадиена являются экономически приемлемыми. При этом нижний поток подают в дегазатор для ацетиленов, из которого отгоняют С 4 -ацетилены, а очищенный растворитель отводят из него в виде нижнего потока. Технический результат - повышение срока эксплуатации установки между циклами очистки в 2 раза за счет снижения температуры в кубе. 10 з.п. ф-лы, 1 табл., 1 ил.

Process for the removal of MAPD from hydrocarbon streams

A process for the selective hydrogenation of the methyl acetylene and propadiene (MAPD) in a propylene rich stream is disclosed wherein the selective hydrogenation is carried out stepwise (a) first in a single pass fixed bed reactor and then (b) in a distillation column reactor containing a supported PdO hydrogenation catalyst which serves as a component of a distillation structure. Conversion and selectivity to propylene in improved over the use of the single pass fixed bed reactor alone.

Oxyalkylation process

This invention relates to oxyalkylations which take place in the presence of solid acid catalysts. More particularly this invention relates to increasing the selectivity of such processes employing a solid acid catalyst, preferably a polyfluorosulfonic acid catalyst, in which an hydroxylic compound reactant reacts with an alkylene oxide reactant to produce a desired mono-oxyalkylated product which tends to react with the alkylene oxide to produce an undesired second product. The improvement comprises the steps of (1) vaporizing the hydroxylic compound in a reflux zone, (2) passing vaporized hydroxylic compound through a catalyst zone to a condenser wherein vaporized hydroxylic compound is condensed, (3) returning condensed hydroxylic compound to the catalyst zone and in the catalyst zone contacting condensed hydroxylic compound with vaporized hydroxylic compound and the alkylene oxide in the presence of a solid insoluble acidic catalyst at reaction conditions whereby the desired mono-oxyalkylated derivative is formed, (4) passing reaction products and unreacted condensed hydroxylic compound to the reflux zone, and (5) recovering the mono-oxyalkylated derivative.
