摘要： This invention provides a method for reclaiming oil from waste plastic in such a way that thermosetting resins and solid foreign matter in the plastic will not pose a problem. This method greatly reduces the burden of presorting the garbage or industrial waste. To achieve this objective when oil is to be reclaimed from a waste plastic containing chlorine compounds, such as vinyl chloride, the plastic must first be stripped of chlorine. Prior to pyrolysis, while being conveyed forward in a continuous stream, the plastic is mixed with heated sand and/or an additive agent to raise its temperature to 250-350.degree. C. This creates a product which is comprised of a mixture of sand and substantially dechlorinated plastic. The product is mixed with heated sand to heat it directly to a temperature of 350-500.degree. C. It is maintained at this temperature until pyrolysis occurs. In order to obtain high-quality oil with a low boiling point, a first gas/liquid separation process separates the product obtained from the aforesaid pyrolysis into liquid high-boiling point oil, gaseous low-boiling point oil and low molecular-weight gases, and recirculates the liquid high-boiling point oil to the pyrolysis process, and a second gas/liquid separation process separates the gaseous low-boiling point oil and low molecular-weight gases into liquid low-boiling point oil and low molecular-weight gases. The first and second gas/liquid separation process are connected in sequence.

摘要： According to the present invention, boiler water is pressurized so that its boiling point is set at approximately 200.degree. C. to 320.degree. C. The boiler water is heated in at least two stages. Thermal energy of gases containing chlorine compounds is used to heat the water to its boiling point. Thermal energy of gases which do not contain chlorine compounds is used to heat the water from its boiling point until superheated steam of a given temperature is generated. The heating which uses the thermal energy of gases containing chlorine compounds is accomplished using the thermal energy from the combustion of pyrolysis gases obtained from a pyrolysis means in which waste material is supplied into a chamber containing a fluidized bed medium which has been heated to at least 300.degree. C., and a pyrolytic reaction is induced. The heating which uses the thermal energy of gases which do not contain chlorine compounds is accomplished using the thermal energy obtained from a char combustion means to combust char in which a char mixture consisting of unpyrolyzed residue and fluidized bed medium removed from the pyrolysis means is fluidized by a stream of air, and the unpyrolyzed residue is combusted.

摘要： This invention relates to a process for the production of absolute alcohol from aqueous alcohol, whereby saving of energy to a greater extent is rendered possible in a more simple process, as compared with the prior art azeotropic distillation method using benzene or cyclohexane. That is, aqueous alcohol is subjected to extractive distillation in a first distillation column under such a condition that a liquid and gas of a solvent simultaneously coexist using low pressure propane, propylene and butane as the solvent, absolute alcohol substantially free from water is recovered from the bottom of the distillation column and subjected to stripping of hydrocarbons in a second distillation column, during which the gaseous phases of the first and second distillation columns are mixed and compressed, utilized through recompression as a heat source of a reboiler of the first distillation column, subjected to separation of water content and recycled to the upper parts of the first and second distillation columns. In accordance with the process, the energy required can largely be reduced.In Examples, the energy required for producing 1 kg of absolute alcohol is reduced to 1/5 to 1/10 of the prior art azeotropic distillation method, which shows the advantages of the present invention.According to the process of the present invention, installations such as compressors, heat exchangers, decanters, etc. can be omitted and the installation cost can be reduced by about 30%.
