PROBLEM TO BE SOLVED: To efficiently concentrate and solidify a salt-contg. soln. at the time of concentrating and solidifying the salt-contg. soln., especially a borate or sulfate-contg. soln-, by the microwave irradiation in a closed vessel by providing a bell-shaped body for a microwave tube and radiating a microwave directly to the salt-contg. soln. SOLUTION: The saltlsoln. to be evaporated and solidified in a preparation vessel 10 is supplied to a vessel 12 by a feed pump through a pipeline 14. A microwave tube 28 is connected to the vessel 12 in the zone of a lid 26 formed in the shape of a diffuser 27, and the vessel 12 is irradiated with a microwave generated by a magnetron through the tube 28 and a bell-shaped body 29. In this case, the cross section of the bell-shaped body 29 or the space between the body and the liq. surface in the vessel 12 is changed, hence the microwave is directly radiated to the liq. surface but not to the side wall of the vessel, and the salt soln. is efficiently heated and evaporated. A jack 37 is provided below the vessel 12 to adjust the height of the vessel 12. |

PURPOSE: To easily obtain an aq. potassium chloride soln. for alkali electrolysis by adding potassium hydroxide or potassium carbonate to an aq. crude potassium chloride soln. to remove the sulfate ions by precipitation.
CONSTITUTION: The precipitates (c) of an aq. potassium chloride soln. (a) are settled in a settling vessel 2, the precipitates (c) are removed by a filter 3, and then the soln. is electrolyzed in an electrolytic cell 4. Subsequently, potassium hydroxide (i) is added to the branched stream of the dil. aq. soln. (e) passed through a dechlorination tank 5 to increase the hydroxide ion concn., and precipitated potassium sulfate (k) is separated by a filter 7. The filtrate (1) is added to the main stream of the aq. soln. (e), potassium hydroxide (m) and potassium carbonate (h) are added to the soln. to increase the hydroxide and/or carbonate ion concns., and the soln. is returned to a salt dissolving tank 1 and recycled.

PURPOSE: To prevent the salt pollution of waste water and to reduce a treatment cost by treating the waste water while recovering potassium sulfate in a waste treatment from two-stages production of perylenetetracarboxylic acid dianhydride.
CONSTITUTION: Perylenetetracarboxylic acid diimide is obtd. in a first stage and perylenetetracarboxylic acid dianhydride by hydrolysis in a second stage. A K
2SO
4 mother liquor is introduced from a preliminary batch into the waste sulfuric acid from the second stage and the mixture is treated with active carbon and is filtered. The filtrate is added to the waste water from the first stage contg. KOH and is neutralized. The reaction product is heated and after a surfactant is added thereto, the product is subjected cooling crystallization. The product is then filtered and the filtrate is treated while potassium sulfate is recovered.

PURPOSE: To recover the subject two components by forming a slurry by controlling the temperature of the aqueous raw material solution comprising glycine and sodium sulfate and separating solid mixture. A part of the mother solution is recycled.
CONSTITUTION: The subject material is recovered by separating the solid mixture from the mother solution by forming slurry by cooling the aqueous raw material solution consisting of glycine and sodium sulfate to a temperature of about 5°C at a rate of 5.8°C/hour. Seed crystals of glycine may be added before cooling the raw material solution, and seed crystals of 10 hydrate of sodium sulfate during the slurry formation. A part of the separate mother solution may be recycled in the crystallizing tank to reduce the density of the slurry. By this method the waste fluid produced in the process of manufacturing glycine can be minimized and valuable materials can be recovered from the waste fluid.
