ABSTRACT:
A continuous particle treating system (10) is shown having an elongated treatment chamber (12) with a slurry supply network (14) connected to the inlet end (12a) of the chamber and an outlet network (16) connected to the outlet end (12b) of the chamber. The supply network includes a loading char (24) coupled to a slurry container (18) forming a main circulation loop and a by-pass conduit (32) connected in parallel with the loading chamber forming a by-pass loop with the slurry container. High pressure liquid (36) is used to pressurize the treatment (12) and at selected times during an operational cycle, the loading chamber (24). A plurality of valves (V1-V7) are interconnected and sequenced to maintain slurry circulation at all times and to intermittently separate the loading chamber (24) from the circulation path and to pass on the slurry in the loading chamber into the treatment chamber (12). She outlet network (16) includes an unloading chamber (40) and a plurality of valves (V8-V10) to remove treated material from treatment chamber (12) and, if desired, to further treat such material at high pressure and/or high temperature before releasing the material to a collection site at atmospheric pressure. The treatment chamber is heated (46) and stirred (48). A programmable controller (44) is used to energize the valves in a selected sequence.
