Use of catalytic wet oxidation of industrial wastewater
On a table in the middle of the cooling of the compressor compression phase from the low pressure (11MPa) out of the gas into a 3 bed, one-way into the middle of the cooling inside, where it can generate the total 1 / 3 of the NH from the converter out of the product is cooled, and about 85% of the total NH can be separated from the gas inside. The remaining gas in the second stage of the compressor to be compressed to about 21MPa,[link widoczny dla zalogowanych], and then added to the NH within the synthesis loop. Company said another advantage of the design are: the exclusion of the low pressure NH, so that the volume of gas decreased by 30%. In addition, the synthesis gas compressor about the application than the general method of the compressor is 20%. Allegedly, in the double-compression method, the investment per ton of product and operating costs close to a single process, in theory,[link widoczny dla zalogowanych], the total number of factories in economically cost-effective. Type oxidation catalyst at Osaka, Japan, recently introduced a wet oxidation method to treat industrial wastewater,[link widoczny dla zalogowanych], activated sludge or the cost and the cost of calcined approach can be reduced by 30% compared to 50%. Using this method, can handle 10 tons per day or more with a variety of substances such as formaldehyde, acetaldehyde, phenol, methyl methacrylate, acetone, tetrahydrofuran (THF), ethylene glycol, sulfide, ammonia, isocyanate and acrylonitrile and other wastewater. However, it can not be directly applied to contain a large number of water-insoluble solids, such as oil and phosphorus in wastewater. Containing 5000 to 150,000 mg l COD (Chemical Oxygen Demand) of water, compressed air and pressure up to 0.9MPa mixed, then heated to 90 ~ 280oC, the temperature by using the waste water type. Then added to a fixed-bed reactor, the reactor is filled with a catalyst made of spherical, the group was divided into a metal oxide and a precious metal. Decomposition of organic material is oxidized into carbon dioxide and water, and nitrogen compounds were decomposed and generate nitrogen. Sulfur and chlorine compounds through the addition of a small amount of alkaline compounds were oxidized, broken down into sulfate and chloride. After the wet oxidation, gas-liquid separator through a station, CO, N, and Oz came out from the water decomposition. According to Nippon Shokubai Company, said the new law to exclude more than 95% of COD, nitrogen compounds and sulfur compounds. The joint group from the Dow Chemical and Asahi Kasei to 50:50 joint venture company in China with annual output of 120,000 tons Zhangjiagang scale production of polystyrene. PS this will be more Asia-Pacific region into the over-supply situation. Starting from August 2002, polystyrene prices have fallen by $ 120 per ton. Currently, the price of the Asia Pacific region only 670 tons ~ ~ $ 690. * 36 * Development of waste water fluoride Mitsui Chemicals Mitsui Chemicals, the new law has developed a removal of fluoride in industrial wastewater in the new method. The first step in the law the same way with the ordinary, that is first conducted in the lime and reaction, and then remove the calcium fluoride precipitate. The greatest feature of the new method is to avoid the original method of complex formation during the reaction, thus reducing costs. Wastewater by a modified filler of inorganic phosphate for wastewater treatment comprising the tower, the filler can accelerate the crystallization of fluoride, and to fluoride adsorption on its surface. In a day of wastewater treatment 60Om3 test, this method of fluoride can be from 1% to Japan, currently licensed 8 �� 10, while the operating cost of traditional methods of only 5O%. United States,[link widoczny dla zalogowanych], \Color PVB film launched to meet the architects and designers inspired by the expression of the same time, the market for expanding applications of laminated glass and consumption will have a positive role in promoting. Vtmceva color intermediate film provides a 1O kinds of basic colors, by the kinds of basic color 1O superposition can actually get 700 color combinations. With these colorful color matching, Vanceva intermediate film 9 is also provided a respected designer patterns, dots, stripes, etc. are the most commonly used in business circles. Vtmceva color intermediate film can continue to maintain its laminated safety glass, security, noise and energy saving advantages. Therefore, the laminated glass to meet the functional requirements at the same time,[link widoczny dla zalogowanych], but also has a decorative. Not only for building walls, windows and doors, building facades, balconies, large plate glass window and can be used for indoor partition, decorative doors and windows, furniture, railings, handrails and so on. U.S. Solutia's current annual revenue of about 3o billion, with 34 manufacturing plants around the world.
