Method of recovering waste paper

Claim 1

A PROCESS FOR REMOVING RESINOUS MATERIAL FROM WASTE PAPER, COMPRISING CRUSHING AND COMPACTING A MASS OF SAID WASTE PAPER IN A FORAMINOUS CONTAINER, CONFINING SAID WASTE PAPER MASS IN SAID CONTAINER IN A TREATMENT PRESSURE VESSEL HAVING TOP AND BOTTOM CONDUIT CONNECTIONS, CONTINUOUSLY PREHEATING A CHLORINATED HYDROCARBON SOLVENT TO A TEMPERATURE OF ABOUT 60*C. TO 70*C., PASSING SAID PREHEATED SOLVENT THROUGH SAID MASS OF WASTE PAPER WHILE STATIONARY IN SAID VESSEL TO REMOVE SAID RESINOUS MATERIAL, WITH THE DIRECTION OF FLOW FROM THE BOTTOM TO THE TOP OF SAID VESSEL, CONDUCTING SOLVENT DISCHARGED FROM THE TOP OF SAID VESSEL TO A SEPARATION PRESSURE VESSEL, DISCHARGING SUPERHEATED STEAM AT A TEMPERATURE OF 150*C. TO 160*C. INTO THE LOWER PORTION OF SAID SEPARATION VESSEL TO VAPORIZE SAID SOLVENT WHILE LEAVING SAID RESINOUS MATERIAL IN AQUEOUS SUSPENSION, CONDUCTING SAID STEAM AND SOLVENT VAPOR TO A CONDENSER TO SEPARATELY CONDENSE AND SEPARATE SAID SOLVENT AND WATER AND THEREBY RECOVER SAID SOLVENT, DISCONTINUING THE FLOW OF SAID SOLVENT THROUGH SAID STATIONARY MASS, FLOWING SUPERHEATED STEAM THROUGH SAID STATIONARY MASS OF WASTE PAPER IN A DIRECTION FROM THE TOP TO THE BOTTOM OF SAID TREATMENT VESSEL TO VAPORIZE AND REMOVE SAID SOLVENT FROM SAID MASS, CONDUCTING SAID STEAM AND SOLVENT TO SAID CONDENSER TO SEPARATE SAID SOLVENT AND WATER, DISCONTINUING THE FLOW OF SAID STEAM THROUGH SAID MASS AND FORTHWITH APPLYING SUCTION TO SAID VESSEL TO REMOVE SAID STEAM THEREFROM, WHEREBY SAID WASTE PAPER IS RECOVERED IN A SUBSTANTIALLY DRY STATE WITHOUT SUBSTANTIAL STRUCTURAL CHANGE BUT WITH SAID RESINOUS MATERIAL REMOVED.
