METHOD FOR REMOVING LIQUID FROM A SLURRY

IOGEN Energy Corporation,...

1. A method of removing liquid from a slurry by a press having an inlet, a deliquefying section, a plug formation section, a discharge section, an outlet, and a restriction cone rigidly attached to a conveyance member that is mounted axially in the press for advancing material therethrough, the method comprising:(i) pressurizing the slurry and feeding the pressurized slurry into the inlet of the press;
(ii) advancing the pressurized slurry through the deliquefying section of the press, thereby removing liquid from the slurry to produce a partially deliquefied slurry and a pressate stream of liquid pressed from the slurry;
(iii) advancing the partially deliquefied slurry to the plug formation section of the press using the conveyance member and compacting the partially deliquefied slurry into an annular space between the conveyance member and a surrounding shell to form an annular plug of material;
(iv) advancing the annular plug of material through the annular space, past the restriction cone, to the discharge section of the press;
(v) removing additional liquid from the annular plug of material by operating the press so that a pressure in the discharge section of the press is greater than a pressure of the pressate stream by at least 2 psi, thereby producing a plug of material having a reduced liquid content; and
(vi) removing the plug of material having the reduced liquid content, or segments thereof, through the outlet of the press.
