Patent ID: 7713490

Claim:
A process for providing a slurry of particulate matter to a reactor of a reactor system comprising: (i) said reactor; (ii) a slurry tank connected to said reactor; (iii) a feed pot connected to said slurry tank; (iv) a day tank connected to said feed pot; and (v) a load cell, wherein said day tank is placed on said load cell, said process comprising the steps of: (a) adding said particulate matter in dry form to said day tank; (b) measuring the mass of said particulate matter in dry form in said day tank using said load cell, and moving said particulate matter into said feed pot; (c) adding said measured particulate matter and a volume of diluent to said slurry tank to form a slurry of said particulate matter; (d) calculating the concentration of said slurry from said measured mass of said particulate matter and said volume of said diluent; (g) continuously withdrawing said slurry from said slurry tank into said reactor; (f) providing means for measuring the mass flow of said slurry out of the slurry tank to the reactor, and determining how much of the first batch of said slurry is left in said slurry tank; (g) determining the volume of said diluent and said mass of said particulate matter left in the slurry tank from step (f); (h) repeating the steps (a)-(d) to refill partially emptied slurry tank with a new amount of said particulate matter and said diluent to keep the concentration calculated in step (d) in said slurry tank, which keeps the constant net amount of said particulate matter fed to said reactor.
