| PURPOSE: To provide a method for removing unwanted impurities and/or by- products by producing non-volatile salts thereof by use of reagents from an aqueous process stream in which such impurities and/or by-products are dissolved. CONSTITUTION: This method comprises, for example, separating formaldehyde as a by-product from an alkylene oxide in a process wherein the alkylene oxide is produced from the corresponding alkene through catalytic epoxidation. This method comprises mixing formaldehyde with a reactant reactive preferentially with the formaldehyde under conditions of a process stream and producing a reaction product or products exhibiting lower volatility than formaldehyde in the aqueous solution, then, removing at least part of the reaction product or products from the process. This method is applicable to processes wherein, e.g. carbonyl-containing impurities, such as aldehydes or ketones, low molecular weight olefins, nitrogen-containing aromatic compounds, nitrogen-containing aliphatic compounds or inorganic compounds are contained as impurities. This method removes impurities on a continuous basis and can be conducted in combination with production processes. COPYRIGHT: (C)1995,JPO | ||||||

| PURPOSE: To make it possible to save detoxication of pump oil by arranging a pyrolysis and precipitation apparatus for volatile and toxic compds. just before a holding pump and providing a cracking apparatus with an exchangeable pack of a packing material. CONSTITUTION: The volatile and toxic compds., such as B 2H 6, PH 3 and AsH 3, come into contact with the pack of such packing material as special steel scrap, where the compds. are heated to 300 to 900°C and the pyrolysis and precipitation of the volatile and toxic compds. are executed. The gases are thereafter sent to the holding pump. The pack of the packing material is exchangeable and the used pack is replaced with a fresh pack. The need for executing the detoxication of the pump oil is thus eliminated. COPYRIGHT: (C)1989,JPO | ||||||

| PURPOSE: To provide a method for preventing soluble heavy metal pollution material existing in a stratum or submarine layer including carbonate from being fluidized again by groundwater by stabilizing the soluble heavy metal pollution material using calcium chloride water solution. CONSTITUTION: This method includes a step to introduce calcium chloride water solution including a stabilized volume of calcium ions into a layer including carbonate. By forming copercipitation materia which is hardly soluble in fluid in the layer from a reaction of the pollution material and carbonate to calcium ions, re-fluidization of the heavy metal pollution material by groundwater can be prevented. | ||||||

| PURPOSE: To fix pollutant by crushing solid materials, adding liquid waste to the crushed materials to obtain a pasty mass, adding pulverulent calcium carbonate, silicium oxide and aluminum and iron oxides to the pasty mass, and incinerating the mixed mass. CONSTITUTION: The solid portions of waste materials are crushed and ground to a granulometry of under 5 mm. After the addition, if applicable, of liquid waste to the granulometry to obtain a pasty mass, an additional material consisting of pulverulent calcium carbonate, silicium oxide and, possibly, aluminum and iron oxides having under 50 μm average particle size is added to the pasty mass to be incinerated at about 750°C to 1350°C. The additional material is changed depending on the type and character of waste materials to be incinerated and a concentration of the final effluent is adjusted to formula I. Thus, high endothermal reaction is occurred by deoxidizing limestone with the inexpensive additional material in the waste incineration treatment to combust a larger amount of wastes at a lower temperature. The burnt residue is insoluble and inert solids. COPYRIGHT: (C)1992,JPO | ||||||

| PURPOSE: To completely detoxify waste hardening salt by melting the waste hardening salt together with specific detoxifying materials to the toxic materials contained therein at an adequate temp. CONSTITUTION: About a half amt. of the waste salt, the total amt. of iron sulfide necessary to cyanide detoxification and the required amt. of the sodium sulfate necessary for conversion of barium carbonate are charged into a salt bath crucible preheated to about 500°C. When the temp. is regulated to about 550°C, the contents in the crucible begin to melt under adequate foaming and volume shrinking. The temp. is raised stepwise and during this time, the remaining waste salt is added to the contents. After the bath surface having luster is generated at about 700 to 750°C, the contents are heated for about 1 to 3 hours up to 900°C to completely convert the barium carbonate to barium sulfate. Consequently, reaction by-products are problem-free and thus underground embeddable. COPYRIGHT: (C)1989,JPO | ||||||
