摘要： Process and apparatus for recovering clean water and solids from aqueous solids are disclosed. Aqueous solids are mixed with a low viscosity, relatively volatile, water-immiscible light fluidizing oil to obtain a mixture which will remain fluid and pumpable after removal of essentially its entire water content. The mixture of solids, water and fluidizing oil is subjected to a dehydration step by means of a plurality of mechanical vapor recompression evaporators operating in staged array whereby substantially all of the water and at least part of the light oil are evaporated and subsequently recovered. The light fluidizing oil is then largely separated from the solids. Residual fluidizing oil may be removed from the solids by direct contact with a hot blowing gas such as blowing steam. The invention is characterized by the conservation of energy through the use of heat exchangers whereby condensate gives up its heat to the feed.

摘要： Apparatus and a proccess for the thermal decomposition of organic material is disclosed wherein the waste solids concentrates are first mixed in a fluidizing tank with a fluidizing oil to form an appropriate mixture which is then dehydrated to remove water from the waste and oil mixture. Subsequently, the waste solids and oil are separated. The resultant dehydrated, substantially oil free organic waste material is then pyrolized within a temperature range of approximately 700.degree. F. to 1800.degree. F. by which lower molecular weight organic compounds are distilled off as organic vapors and gases while a residue of char and ash remain.

摘要： Process and apparatus for recovering clean water from aqueous wastes by evaporation while avoiding scaling and fouling as well as corrosion of the evaporator tubes. Addition of an oil, preferably a volatile oil, to the aqueous waste feed results in the formation of a coating of said oil on the surfaces of the tubes, thereby preventing corrosion and fouling and build-up of scale deposits. Volatile oil that distills over is separated from the aqueous distillate by conventional means and may be recirculated.
