摘要： PURPOSE:To allow the selective permeation of the gaseous CO2 and steam contained in the air supplied on a primary side to a secondary side by sealing a soln. having high solubility and diffusibility to the gaseous CO2 and the steam between two sheets of thin films having excellent gas permeability and providing a pressure difference between the primary side and the secondary side of the thin films. CONSTITUTION:The soln. having the excellent solubility and diffusibility to the gaseous CO2 and the steam is sealed between 5 the thin films having the characteristics to allow the high permeation of gases but do not allow the permeation of liquid. The circulating air 3 in the hermetic space is introduced to a supply gas cell 6 segmented by the liquid film 5 of the film module 4. The secondary side of the liquid film 5 is in contact with a permeated gas cell 7 and this cell is maintained under a reduced pressure by a vacuum pump 8. The gaseous CO2 and steam contained in the circulating air 3 introduced into the cell 6 permeate to the cell 7 side while the gas and steam are selectively dissolved and diffused in the liquid film 5 by the pressure difference between both sides of the liquid film 5 as a driving power; thereafter, the gas and steam is taken out as a permeated gas 9 via a vacuum pump 8.

摘要： PURPOSE:To enhance the efficiency of removing moisture by specifying the temp. near the gas outlet side in the packed layer part of a packed column at the time of removing the moisture and at the time of regeneration by heating. CONSTITUTION:A temp. distribution in which T1 (-90 deg.C) is attained on the top end side of the packed column 1 and T2 (-100 deg.C) is attained on the bottom end side of the column 1 is set. The moisture contained in a gas 5 to be treated is prevented from quickly condensing or solidifying, since the top end part of the column 1 is set at the temp. T1. Only the slight moisture corresponding to the temp. T1 is removed. The gas 5 flowing into the column 1 is slowly cooled while the gas is brought into contact with the packing material 4 in the column 1. Generation of local clogging near the gas inlet is thereby prevented.

摘要： PURPOSE:To carry out switchovers of adsorption towers without analyzing gas component, by sensing at least one item of volume, weight, pressure and electric resistance of an adsorbent and switching over directional control valves of inflow and discharge from and into an adsorption tower based on said sensing. CONSTITUTION:Fluid to be treated is flowed into an adsorption tower 1a, and when adsorption is progressed, the volume of an adsorbent 2 is expanded and bellows 4 are stretched to contact with a contact point 3' with the contact point of a limit switch 5, putting an 'ON' command into a control device 8 actuating to close automatic valves 6a and 7a and to open automatic valves 6b and 7b, and the flow of fluid to be treated is switched over to an adsorption tower 1b. In addition to the above, by measuring the variation of weight of the adsorbent 2, the wall pressure of the adsorption tower 1 and resistivity of the adsorbent 2, said valves can be controlled.

摘要： PURPOSE:To obtain a directly reusable solvent acetic acid ester with a low acetic acid content, by separating the recovered solvent, collected by the active carbon adsorption method and containing the acetic acid ester into the aqueous phase and solvent phase, bringing the solvent phase into contact with potassium carbonate to deacidify the solvent and dehydrating and purifying the resultant deacidified solvent. CONSTITUTION:A raw gas containing an acetic acid ester as a solvent is passed through a pretreating apparatus 101, e.g. filter, and fed to an adsorption tank 103 to adsorb the acetic acid ester in active carbon 103-1. The adsorbed acetic acid ester is then desorbed with steam (E), condensed and liquefied in a condenser 104. The liquefied acetic acid ester and water are separated in a separator 105, and the aqueous phase is fed to a dehydration column 106 to recover the solvent contained in the aqueous phase. The recovered solvent is then returned to the separator 105, and the solvent phase is fed to a catalytic deacidifying column 111 and brought into contact with an aqueous solution of potassium carbonate or sodium carbonate to neutralize and convert acetic acid into K salt or Na salt. The resultant solvent is then dehydrated in a dehydration column 108 and purified in a purification column 114 to recover the aimed purified acetic acid ester with

摘要： PURPOSE: To reduce the amt. of regenerating gas as little as possible in the dehumidification of radioactive gas by providing heat conducting fins connected with each other within an adsorbent layer in the inside of an adsorption tower and providing a heating device to the outside of the tower.
CONSTITUTION: Heat conducting fins 6 are provided to the inside of a fixed bed type dehumidifying tower 10 packed with an adsorbent 4; a heating device 9 such as electric heater, etc. is provided to the external wall of the dehumidifying tower 10. A double tube part 8 is provided to the external wall of the dehumidifying tower 10 to form a passage of cooling gas 7. In this treating system for radioactive gas, regenerating gas 5 is introduced from the bottom of a dehumidifying tower 10B which has adsorbed the moisture in the radioactive gas, and the adsorbent 4 is heated by heat conduction with the heating device 9 and the heat conducting fins 6 and regenerated in a short time. After the regeneration is finished, the heating of the heating device 9 is ceased, and the cooling gas 7 is passed through the double tube part 8, thus heat conduction of the heat conducting fins 6 and a cooling stage are finished quickly. The regenerating gas 5 contg. moisture discharged from the dehumidifying tower 10B is mixed with wet gas 1 and fed to a dehumidifying tower 10A through a cooler 14.

摘要： PURPOSE:To recover valuable matters from waste ink and to obtain reclaimed ink from recovered pigment, by adding a solvent having a poor pigment-dispersibility to waste ink to precipitate and separate pigment particles, and mixing the separated pigment with a solvent capable of highly dispersing the pigment. CONSTITUTION:A solvent having a poor pigment-dispersibility or a mixture thereof with a solvent capable of highly dissolving resins is mixed with waste ink to agglomerate pigment particles in said waste ink and to precipitate and separate the particles. A solvent capable of highly dispersing pigment is mixed with the separated pigment to re-disperse the pigment therein, thus obtaining a reclaimed ink. Examples of said solvents having a poor pigment-dispersibility are arom. hydrocarbons such as toluene and xylene. Examples of said solvents capable of highly dissolving resins and poorly dispersing the pigment are methyl alcohol and ethyl thetl acetate. The pref. mixing ratio of the solvent having a poor pigment-dispersibility/the solvent capable of highly dissolving resins is 100/ 0-50/50 by vol.
