摘要： PURPOSE:To enable a liquid mixture with aggregates to be dispersed rapidly and uniformly by arranging the tip of a mobile nozzle to be pressed by a spring at an opposite position to the tip of a fixed nozzle which supplies the liquid mixture at high pressure, then forming a high pressure Slit part between both nozzle tips, and supplying the mixture under pressure so that a specific pressure difference is maintained across the slit. CONSTITUTION:The tip of a mobile nozzle 6 to be pressed by a spring 8 is arranged at an opposite position to the tip of a fixed nozzle 3 which supplies a liquid mixture with aggregates and a high-pressure slit part is formed between both tips. Further, the mixture is supplied under pressure so that a pressure difference of 250kg/cm min. is maintained before and after the slit part. Consequently, it is possible to disperse the liquid mixture with the aggregates of fine particles uniformly and rapidly.

摘要： PURPOSE:To decaffeinate raw coffee beans by a method nontoxic to human bodies without losing active ingredients by pressurizing and heating the raw coffee beans in the presence of water, treating the coffee beans with specific combination of C2H5OH and CO2 and then drying the treated coffee beans. CONSTITUTION:Raw coffee beans are pressurized and heated in the presence of water and then dipped in an aqueous solution of ethyl alcohol in a concentration so as not to destroy cell tissues thereof to produce pretreated raw coffee beans (pretreating step). The pretreated raw coffee beans are subsequently brought into contact with a mixed solvent consisting of CO2 in a supercritical state and an aqueous solution of ethyl alcohol in a concentration so as not to destroy cell tissues thereof or CO2 in the supercritical state and water to extract caffeine (extracting step). The raw coffee beans after extracting the caffeine are then dried (drying step). Thereby, decaffeination of the raw coffee beans is carried out. Only the caffeine present on the peripheries of the cells in the coffee beans is relatively rapidly extracted to minimize elution of proteins, fats and saccharides which are active ingredients of the coffee according to the above-mentioned method.

摘要： PURPOSE:To inject CO2 into the ground under low pressure. CONSTITUTION:The CO2 is introduced into a CO2 booster 2 from a line 1, boosted and then introduced into the upper part of a pipe 9 piercing the ground from a CO2 forcible feed line 5. When the liq. CO2 is introduced from the line 1, it is passed through a heat exchanger 4 and heated. Water is supplied from a line 6, pressurized by a pump 7 and introduced into the pipe 9 from a line 8. The CO2 from the line 5 and the water from the line 8 are mixed in the pipe 9, and the sp.gr of the fluid in the pipe becomes higher than the CO2 alone. Accordingly, the static pressure generated by the fluid in the pipe is increased at the tip 14 of the pipe 9 in proportion to the density. Consequently, the CO2 from the line 5 at a low pressure is forced into the aquifer 13 under pressure from the tip of the pipe 9.

摘要： PURPOSE:To recover water and n-butanol of high purity from a spent solvent consisting of a mixture consisting of n-butanol, butyl acetate, water, 2- butoxyethanol and 2-hexyloxyethanol. CONSTITUTION:A solvent mixture to be treated is given phase separation into a water phase and a solvent phase in the 1st separation tank 2. The solvent phase is passed through the 1st distillation column 5, the 3rd distillation column 19 and the 4th distillation column (vacuum) in order and n-butanol of high purity is recovered from the bottom of the 4th distillation column. After the water phase separated in the 1st separation tank is mixed with a distillate part from the top of the 1st distillation column, it is given phase separation in the 2nd separating tank 10. The separated solvent part is refluxed to the top of the 1st distillation column. The water phase separated in the 2nd separation tank is introduced into the top of the 2nd distillation column 15 and water substantially not contg. solvent components is recovered from the bottom and top gas is added to the 2nd separation tank after condensation.

摘要： PURPOSE:To produce gasohol by a simplified process which can accomplish marked reduction of energy consumption and requires low cost of building by subjecting an ethanol/water mixture and gasoline to countercurrent extraction under conditions of specified temperature and specified pressure and cooling the gasoline phase to separate it into a water phase and a gasohol phase. CONSTITUTION:A crude alcohol of a concentration of 10-20wt.% enters a feed line 1, is preheated in heat exchangers 2 and 4, and fed to the top of a countercurrent alcohol extraction tower 6 through a feed line 5. gasoline preheated in heat exchangers 15, 11 and 21 is fed to the bottom of the tower 6 through a feed line 7. Because of its good affinity for gasoline, the ethanol in the water phase is selectively extracted with the gasoline phase (at an extraction temperature of about 80 deg.C or above). The temperature of the gasoline phase leaving the tower 6 through a line 10 is lowered to 10-60 deg.C to effect the phase separation of the water and to thereby markedly decrease the water content of the gasoline phase. Substantially, water-free gasohol is with-drawn from a line 14, cooled, brought into a state of atmospheric pressure by means of a pressure reducing valve 16 and fed to a gasohol storage tank 18.

摘要： PURPOSE:To readily obtain the title substance, useful as various detergents and having a narrower addition molar distribution, by extracting an aliphatic alcohol ethoxylate with CO2 in a supercritical or pseudocritical state as an extracting agent. CONSTITUTION:Ethylene oxide is added to an aliphatic alcohol in the presence of an acidic or basic catalyst to provide the title substance having an ethylene oxide addition molar distribution. The resultant substance is then extracted with CO2 in a supercritical or pseudocritical state as an extracting agent to afford the title substance having a narrower addition molar distribution. The supercritical state refers to a state in which the CO2 is kept at a temperature under a pressure of >=31 deg.C critical temperature and >=73atm critical pressure. The pseudocritical state refers to a state in which the CO2 is kept at >=20 deg.C under >= the saturation vapor pressure thereof at the temperature and-other than the critical state. Since the CO2 is not heated at high temperatures by the above-mentioned method, there is no fear of coloring or degradation and deterioration and the ash content is low.

摘要： PURPOSE:To enable a leak portion of hydrogen sulfide to be easily specified by dissolving and diffusing a pigment, a surface-active agent, an organic solvent, and ferric chloride to a dilution liquid solution of hydrochloric acid or sulfuric acid and adding p-aminodimethylaniline dihydrochloride, etc., to it. CONSTITUTION:A pigment such as TiO2, SiO2, and CaCO3, a surface-active agent, an organic solvent, and ferric chloride are dissolved and diffused by pure water and a small amount of hydrochloric acid or sulfuric acid is added to it. Furthermore, p-aminodimethylaniline dihydrochloride or chlorodimethyl-p- pheynylene dihyrochloride is added to obtain a white slurry liquid. This solvent is coated and sprayed to a welding portion and a connection portion of a plant, a machine, a device, etc., which handle hydrogen sulfide. When a lead of hydrogen sulfide is detected, p-aminodimethylaniline-2 hydrochloride becomes blue under presence of ferric chloride and this is highlighted by white color of the pigment. For example, a coated surface 8 of a detection agent is formed at a welded portion 7 where a piping 6 which allows a gas containing hydrogen sulfide to flow is joined to detect the leak.
