摘要： An apparatus for desulphurising exhaust gas has a cylindrical housing, the axis of which is virtually vertical and which can rotate about the axis, and has a package section of an adsorbent material which is placed in the vessel. In the apparatus, the inside and the outside of the vessel are subdivided into at least four segment zones by claddings and sealing means along the edge, which segment zones serve particularly for absorption, desorption, cooling and exchange of the adsorbent. As a result, the sulphur oxides are removed from the exhaust gas by adsorption to the adsorbent and on rotation of the vessel, the package zone of the adsorbent is displaced, circulating in position to each of the zones, so that the adsorbent is desorbed, cooled and exchanged. The improvement contains a packing section of a packing material of smaller particle size than that of the adsorbent which is placed in the vessel and the outside of the adsorbing packing section so that it conducts the exhaust gas through the packing section of the adsorbent, this and the packing being able to be exchanged independently of each other in the respective packing sections.

摘要： Wet process for desulphurisation of flue gas uses lime as absorbent. The gas contg. sulphur oxides is washed with a liq. absorbent contg. calcium hydroxide or calcium carbonate. The feature of the invention is use of two different absorption stages. The first stage is operated in a pH range of 3.5-4.5 and the second stage in a pH range of 6.5-7.5. The content of unreacted lime finally passing to the gypsum recovery plant is very low.

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 thermally decomposing and reforming an organic waste such as municipal wastes as a raw material under specific conditions. removing solid content and impurities from the product and subsequently directly synthesizing methanol from the synthesized gas without the generation of CO2 and NOX. CONSTITUTION:The thermal decomposition and reformation of organic waste such as municipal wastes are performed in an oven 1 at 400-1200 deg.C, preferably 500-1000 deg.C, so that the composition of the produced gas is controlled in an al l carbon/hydrogen molar ratio of 1/>=1, preferably 1/(2-5). Solid content and impurities contained in the produced gas are removed with devices 12 and 14, and the synthesized gas thus purified is finally subjected to the direct synthesis of methanol from the synthetic gas in a methanol synthesis tower 18. The method does not cause the generation of CO2 and NOX and has a large economical effect.

摘要： PURPOSE:To uniformize the flow of gas to a large number of gas-liquid dispersing devices, by placing the recirculation pump of the liquid in a cylindrical body outside said cylindrical body and forming a recirculation liquid discharge port and a recirculation liquid supply port into a concentric circular double pipe structure at the central part of the lower part of the cylindrical body. CONSTITUTION:A gas-liquid dispersing plate equipped with a large number of gas-liquid dispersing devices 9 and a recirculation liquid take-out pipe 5 are provided in the cylindrical body 1 being the main body of a reactor. A recirculation pump 6 is placed outside the cylindrical body 1 and a recirculation liquid is uniformly supplied to the liquid phase part (b) in a plenum chamber from a recirculation liquid take-out pipe 5 and a recirculation liquid supply pipe 7, both of which form a concentric circular double pipe structure (5 is set to an inner pipe) at the central bottom part of the cylindrical body 1, in an axially symmetric manner. A treatment liquid is supplied to the plenum chamber along with the recirculation liquid through the recirculation liquid supply pipe 7. By this method, the liquids can be almost uniformly supplied to the plenum chamber and the variation of the gas-liquid interface being formed can be reduced.

摘要： PURPOSE:To enhance separability by carrying out an absorption process and an adjusting process of adsorbing slurry and separating process to separate the same into plaster slurry and line stone. calcium sulfite slurry, and irradiating ultrasonic waves to slurry in the separating process. CONSTITUTION:Combustion exhaust gas 102 and absorbing slurry coming from a spray pipe 105 are contacted in an adsorption tower 101 to adsorb SO2, and exhaust gas is exhaust in the from of purified gas 107. On the other hand, limestone slurry is fed from a limestone feeding tube 109 into absorbing slurry to form calcium sulfite.

摘要： PURPOSE:To reduce the length of a flue and to prevent the deposition of materials in the flue by making the first chamber of a dust collector empty or providing a vacant chamber at the preceding stage in a waster water reducing system wherein waste liq. from the dust collector is injected into the upstream of a dry dust collector. CONSTITUTION:The waste gas is introduced into a dry dust collector wherein dust is removed and then introduced into a wet dust collector wherein gaseous sulfur dioxide, etc., is removed. The waste water from the wet dust collector is neutralized and injected into the upstream of the dry dust collector 2 and the dry solid matter is removed in the dry dust collector 2. In this process, the first chamber of the dry dust collector 2 is made empty or a vacant chamber is provided at the receding stage of the dry dust collector 2. Consequently, the length from a spray nozzle 1 to the dust collector can be reduced to 1/4 of that in the conventional process with the dust collection efficiency unchanged. Accordingly, the length of the flue necessary for the evaporation of waste water can be decreased, the deposition of materials in the flue is eliminated and the working rate can be enhanced.
