Apparatus and process for the pyrolysis of waste solids concentrates
TLDR
In this paper, an approach for the thermal decomposition of organic material is described, in which the waste solids concentrates are first mixed in a fluidizing tank with fluidizing oil to form an appropriate mixture which is then dehydrated to remove water from the waste and oil mixture.Abstract:
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° F. to 1800° F. by which lower molecular weight organic compounds are distilled off as organic vapors and gases while a residue of char and ash remain.read more

Apparatus and process for dehydrating waste solids concentrates
TL;DR: Greenfield et al. as discussed by the authors described an apparatus for drying waste solids concentrates, e.g. sewage sludge, where the concentrate is mixed with a relatively nonvolatile oil in a tank 4 to obtain a pumpable fluid and then subjected to a plurality of sequential dehydration steps in evaporators 9, 21, 32 through which the mixture passes in co-current downward flow with steam originally from a furnace 11 to evaporate off a portion of the moisture, the vapours evolved being utilized in all but the last evaporator to supply a substantial portion of heat requirements
