摘要： PROBLEM TO BE SOLVED: To provide a high temperature exhaust gas treatment method enabling to cool high temperature exhaust gas down to a temperature allowing the treatment with a final dust collector without depositing and producing molten components or dust in the high temperature exhaust gas on the inner wall of a cooling tower. SOLUTION: The treatment method for the high temperature exhaust gas 5 comprises introducing the high temperature exhaust gas 5 including dust via flues into the cooling tower 2, and spraying cooling water to the high temperature exhaust gas 5 to be cooled in the cooling tower 2. In the planar view of the cooling tower 2, the high temperature exhaust gas 5 is introduced into the cooling tower 2 via the two-line flues 3a, 3b while holding equal flowing rate and amount therein. Axial center lines 3ac, 3bc of the two-line flues 3a, 3b are opposite and approximately perpendicular to an axial center line 2c extending in the vertical direction of the cooling tower 2.

摘要： PROBLEM TO BE SOLVED: To provide a process for producing a polylactic acid, whereby the lactide vapor discharged from the reactor can be trapped and recovered without fail without the necessity for a solvent, etc. SOLUTION: This process comprises polymerizing a lactide through ring opening in a polymerizer. In this process, the lactide vapor discharged from the polymerizer is trapped by solidifying it by cooling to the melting point of the lactide or below, and the lactide is recovered by liquefying the solidified lactide by heating. In an embodiment, a heat exchanger is disposed downstream of the polymerizer, and the lactide vapor discharged from the polymerizer is introduced into the exchanger. It is then cooled to the melting point of the lactide or below to trap it in the form of a solid lactide. The solidified lactide in the exchanger is liquefied by heating to recover the lactide.

摘要： PROBLEM TO BE SOLVED: To provide a process for producing a polylactic acid, whereby the polymerization temperature can be controlled with good accuracy. SOLUTION: This process comprises polymerizing a lactide through ring opening in a polymerizer. In this process, the temperature in the polymerizer is controlled by removing heat from the polymerizer by vaporizing the lactide. It is desirable that the amount of the lactide vaporized is regulated by controlling the pressure in the polymerizer, and it is recommendable that the polymerization reaction is continuously performed by using a plurality of polymerizers connected with each other.

摘要： PROBLEM TO BE SOLVED: To produce a polylactic acid by the ring-operating polymn. of a lactide while trapping unreacted lactide vapor from the reaction system with water so as to minimize the unreacted lactide vapor to be absorbed on the ejector side to efficiently recover the vapor and also to prevent an ejector nozzle from clogging. SOLUTION: In producing as polylactic acid by the ring-opening polymerization of a lactide in a polymn. reactor 1, unreacted lactide vapor from the reaction system is cooled in a heat exchanger 3 and the lactide in the form of a liquid or solid is partially recovered in a drain pot 4. The balance of the unreacted lactide vapor is sent into a barometric condenser 7 and trapped with water fed through the to of the condenser and cooled with a heat exchanger 10(5: ejector). Lactic acid is recovered from the water contg. the trapped unreacted lactide by concn.

摘要： PROBLEM TO BE SOLVED: To produce a biodegradable polyester which does not contain any low-molecular substance and is excellent in moldability by treating a polymer which contains lactic acid units as the smallest main structural units and is a copolymer and/or a blend with another polymer in a vacuum in a molten state. SOLUTION: A comonomer to be copolymerized with lactic acid is a polyhydric alcohol, a hydroxy carboxylic acid, an aliph. polyester, an arom. polyester, an aliph. polyamide, or a cyclic compd. (e.g. β-propiolactone) and may be copolymerized in block or at random., and at least one comonomer is used. A polymer to be blended is pref. a biodegradable plastic. The degree of vacuum is kept equal to or below the vapor pressure of the low-molecular substance, generally 100mmHg or lower. Vacuum is applied in the latter half of the polymn., pref. at a conversion of about 70-95%. The heating temp. is lower than the m.p. of and higher than the decomposition point of the polymer, generally 150-350 deg.C. The low-molecular substance removed is mainly unreacted lactide.

摘要： PURPOSE:To enable stable operation a blast furnace at the time of blowing a large quantity of fine coal by specifying charged hydrogen rate and oxygen enriching according to a specified pulverized coal blowing rate. CONSTITUTION:In the blast furnace operation blowing the fine coal, the fine coal blowing rate is made to be >=150kg/t-p and the charged hydrogen is made to 15-20kg/t-p, and further, the oxygen is enriched to 3-5%. The charged hydrogen is supplied from moisture in the air in blasting, the hydrogen in a coke and hydrocarbon in the fine coal, etc., and the shortage quantity is charged as the steam from a tuyere. By this hydrogen charge, the raceway is deepened and the ventilation in the furnace is improved and the lowering of thermal efficiency is prevented. Further, the oxygen is supplied by enriching the oxygen rate in the blasting to about 24-26%. By enriching the oxygen, the lowering in the heat flowing ratio is restrained and the lowering in the thermal efficiency can be prevented.

摘要： PURPOSE:To prevent increase in pressure resistance at hot blast passage in a tuyere and degrading of permeability at furnace core and to improve operational efficiency by operating while blowing solid fuel from a solid fuel blowing hole arranged at bosh part in a blast furnace. CONSTITUTION:In the blast furnace 1 blowing the solid fuel from a blowing lance 5 inserted in a tuyere 2, the blowing lance 6 is arranged separately with the lance 5 in the bosh part 4 in the blast furnace 1, and a part of the whole blowing solid fuel is blown from the lance 6 with insert gas. As the solid fuel from the lance 6 is not passed through the tuyere 2, increase in the pressure in the tuyere can be prevented and a large amount of the solid fuel can be blown while stably continuing the blowing from the tuyere. Further, as the blowing of solid fuel is executed from higher position than the tuyere with the inert gas, the solid fuel blown under non-burning condition is not allowed to flow into the furnace core 7, the permeability in the furnace core is not degraded.

摘要： PROBLEM TO BE SOLVED: To provide a process for producing a biodegradable polyester which contains small amts. of impurities derived from a catalyst or a catalyst diluent. SOLUTION: This is a process for producing a biodegradable polyester by adding a minute amt. of a catalyst to a polymn. material before the polymn. In this process, the catalyst is diluted with a molten polymn. material kept at its m.p. or higher but substantially at a temp. lower than the polymn. initiation temp. and then is added to the polymn. system. This process is suitably applied in producing polylactic acid from lactide.
