    摘要： Disclosed is an economical process for treating a large amount of plastics waste in which thermoplastics, crosslinked plastics, thermosetting plastics or a mixture thereof can be continuously and rapidly degraded and converted into oil without sorting various types of plastics waste. According to this process, powdered plastics obtained by grinding thermoplastics, crosslinked plastics, thermosetting plastics or a mixture thereof is mixed with water to form a slurry, and a dispersing agent such as a water-absorbing resin, a water-soluble polymer or a surface-active agent is added thereto. The resulting mixed slurry is fed to a tubular continuous reactor where the powdered plastics is degraded under reaction conditions causing the water to be in or near its supercritical region. Finally, oil is recovered from the reaction product.

    摘要： A method and system for desulfurizing flue gas in which desulfurization is effected by bringing absorbent slurry containing limestone into contact with flue gas. The method classifies absorbent slurry extracted from a desulfurization absorber, returns a fine-side fluid to the desulfurization absorber, and sends a coarse-side fluid to a solid-liquid separator. Supplied limestone powder is mixed to yield limestone slurry by a solid-liquid mixer, and the limestone slurry is classified, sending the small-particle fluid component thereof to the desulfurization absorber, and sending the large-particle fluid component thereof to a limestone fine grinder. And, limestone contained in the large-particle fluid component is finely ground by the limestone fine grinder and the finely ground limestone is sent to the desulfurization absorber. According to the desulfurization method and system, the concentration of limestone in the desulfurization absorber is increased while the concentration of residual limestone in by-product gypsum is kept low, whereby the desulfurization performance of the absorber can be enhanced, and the operation power for the whole system can be decreased.

    摘要： A wet exhaust gas desulfurization apparatus includes a housing, an absorbing solution (3, B) stored in the lower portion of the housing, a flue (1, 2, 11, 12, 21, 25) above the surface of the absorbing solution, and a partition plate (4, 15, 25) for dividing the flue into gas inlet and outlet portions. Exhaust gas is introduced as an untreated combustion gas from a space above an absorbing solution (3) divided by a partition plate (4) into the wet exhaust gas desulfurization apparatus, the lower edge (5) of the partition plate is immersed in the solution, pressure of the exhaust gas lowers the upper level (6) of the solution on the upper side of the plate to a level (6') through which the gas passes and flows under the partition plate in contact with the solution leaving the solution on the other side of the plate and then discharges through a space above the absorbing solution on the other side of the partition plate. The plate may be raised and lowered by a rack (4') and pinion ( 4") device, and water jet devices (29) may be used to wash absorbing solution off the surfaces (27, 28) of the plate continuously or intermittently.

    摘要： The present invention is directed to a method for treating a waste gas to separate and recover gypsum and a dust therein, characterized by comprising the steps of causing the waste gas to pass through a dry dust collector; introducing the gas into a gas absorber, in which a slurry containing at least one of calcium hydroxide or calcium carbonate as an absorbent is employed to remove SO.sub.2 and the dust passed through the dry dust collector from the waste gas; blowing air into the resultant absorbing liquid in the gas absorber to oxidize the absorbing liquid and to thereby produce gypsum; delivering them to an absorbing liquid tank, in which the slurry mainly containing the gypsum grains is separated from the other slurry mainly containing the dust by partition walls disposed therein; and directly taking out the respective slurries separately from the absorbing liquid tank.

    摘要： In a flue gas treating system, an absorption tower (21), a reheating section (22) and a fan (23) are arranged in line on a vertical axis so as to function as at least a part of a stack for emitting the treated flue gas into the atmosphere. Moreover, in a flue gas treating process, the amount of ammonia injected in the denitration step (a denitrator (2)) and/or the amount of ammonia at a point downstream of the denitration step are determined so as to be on such an excessive level that ammonia or ammonium salt will remain in the flue gas introduced into the desulfurization step (absorption tower (21)). Thus, the size and cost of the equipment can be reduced.
