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： There is provided a method for flue gas desulfurization which is capable of conducting minute control of oxidation and which is capable of maintaining the concentration of sulfurous acid in an absorbent liquid within a proper range in a highly reliable and efficient manner, even in the case where an abrupt change occurs in the operational conditions of the system. In the method for controlling the oxidation in flue gas desulfurization, the value of proportional sensitivity K in the feed back control process, which is based primarily on the oxidation-reduction potential, is increased depending on the deviation .epsilon. in a region where the detected oxidation reduction potential value PN is below the target oxidation reduction potential value SN in correspondence with the characteristic change of the oxidation-reduction potential against the concentration of sulfurous acid.
