ABSTRACT:
By utilizing two inlet pumps and one discharge pump, and controlling the speed of the discharge pump, the pressure in a slurry processing unit can be controlled to facilitate measurement and handling of compressible slurry. It has been found that multiple specific gravity measurements with water injection between the measuring stations can provide an accurate indicate of clear water to be added, even though the slurry is compressible and of varying composition, by allowing controlled undershooting of the required water at one or more injection stations, followed by accurate specific gravity measurement under closely controlled pressure and flow rate conditions, followed by a small final clear water addition. Flow from an inlet clear water pump is distributed through at least two clear water injection pipes, including a first clear water injection pipe connected to slurry piping between the first and the second specific gravity sensors and a second injection pipe connected to the slurry piping between second and third specific gravity sensors. A controller receives analog signals from the specific gravity sensors and from the flow sensors and sends throttle signals to the clear water throttle valves and a speed control signal to the variable speed discharge pump.
