摘要： PURPOSE:To obtain a method and a device for controlling the contact interface position of a pressure vessel, which can maintain the height of the contact interface between the fluid to be treated and the supercritical fluid inside of the pressure vessel constant. CONSTITUTION:A laser beam at a width of X is made incident upon the fluid 27 to be treated and the supercritical fluid 28 to measure damping factors A, B of the laser beam, which is transmitted through the fluid 27 to be treated and the supercritical fluid 28. Next, a damping factor C1 of the laser beam at the time when the laser beam is made incident upon the fluid 27 to be treated or the super critical fluid 28 at a desired position is measured. A reference value C2 of the damping factor C1 in the case where the existence of the contact interface at a reference position separated from the upper end of the laser beam, which is positioned at a desired position, with a distance Y in the vertical direction is assumed is computed with an equation (1). In the case where the damping factor C1 is smaller than the reference value C2, supply quantity of the fluid 27 to be treated is made excessive, and in the case where the damping factor C1 is larger than the reference value C2, discharge quantity is made excessive to maintain the contact interface at the reference position. Reference value C2=A(1-Y/X)+B(Y/X)...(1).

摘要： PURPOSE:To suppress foaming at the time of recovering the raffinate and to continuously and stably extract a supercritical gas by keeping the raffinate introduced into a second separator at a high pressure to prevent rapid foaming in the separator, heating the raffinate stably at a temp. where the raffinate is not degraded and separating the gas dissolved in the raffinate. CONSTITUTION:A foamable liq. material (e.g. honey) is introduced into an extractor 1, and supercritical CO2 is introduced into the extrator 1 and brought into contact with the material to extract the desired substance in the material in CO2. CO2 incorporating the extract is introduced into a first separator 2. The raffinate in the extractor 1 is kept above the pressure where the liq. material begins to foam and introduced into a second separator 3 heated to a temp. where the raffinate is not degraded and the gas dissolved in the raffinate is separated. The raffinate is heated and retained for a specified time in the second separator 3, the gas dissolved in the raffinate is separated and discharged, and the extractant after gas separation is discharged into the atmosphere.

摘要： PURPOSE:To prevent pulsation in high pressure fluid such as aqueous carbon dioxide with the use of a highly durable equipment while preventing impurity from entering the high pressure fluid in a super critical fluid chromatograph separating device or the like. CONSTITUTION:A metal cover plate 12 is fixed to a metal container body 11 so as to form a pressure container which serves as an accumulator 1. A temperature sensor 14 is pivotally fitted into the container body 1 through the cover plate 12 at the center of the latter. A heater 15 is laid around a cylindrical part 11a of the container body 1. A connecting pipe 13 is communicated with a pipe line through which a high pressure fluid flows, so that the high pressure fluid is led into the container body 1 through the connecting pipe 3. The container body 1 is heated while the temperature of the interior of the container body 1 is monitored so as to gasify (evaporate) the high pressure fluid in the container body 1, thereby pulsation in the high pressure fluid flowing through the pipe line may be absorbed through this elasticity of this gas.

摘要： PURPOSE:To obtain the titled high-quality extract with a high extraction efficiency, by extracting coffee with carbon dioxide in a liquid state under specific super critical condition. CONSTITUTION:Parched coffee beans are filled in an extractor 5 and liquid carbon dioxide is fed from a storage tank 1 under 100-300kg/cm pressure by a pump 3 to extract the coffee beans at a temperature adjusted to 5-30 deg.C. Pressure is reduced by a pressure control valve 6 to gasify the carbon dioxide in a separator 7 and the aimed extract is taken from the bottom of the separator.

摘要： PURPOSE:To provide an extractor using supercritical carbon dioxide for easily and effectively separating the desired components from supercritical carbon dioxide. CONSTITUTION:Supercritical carbon dioxide heated by heat exchangers 13, 16 and pressure-increased by a pump 14 is supplied to an extractor 20. The outflow side of the extractor 20 is connected to the 1st separator 22 for separating low soluble components. The outflow side of the 1st separator 22 is connected to the 2nd separator 25. Above the 2nd separator 25, a fractionating column 26 is installed. To the side part of the fractionating column 26, nine heaters 27 are successively attached. Inside the fractionating column 26, a temp. gradient with which the temp. is raised from the bottom part to the top part of the fractionating column 26 over the specified temp. range is given to the supercritical carbon dioxide. To the top part of the fractionating column 26, the 3rd separator 31 for separating low soluble components is connected.
