Abstract:
An article stacking apparatus is provided having a barrel, a frame, a motor, and a drive mechanism. The frame is configured to support the barrel for rotation in a recumbent position. The drive mechanism couples together the frame and the motor to rotate the barrel to agitate cups within the barrel for stacking into accumulated configurations. A method is also provided.
Abstract:
Disclosed is an improved process for the liquid phase coking of spent wood pulping liquors wherein a part of the decoked effluent is flash vaporized to supply condensate for SO2 absorption, thus eliminating the need to absorb SO2 from an oxygen-containing flue gas into sulfite ion-containing coker effluent, thereby minimizing sulfite ion oxidation and reducing the amount of makeup chemicals required to reconstitute the pulping liquor. The process is applicable to all acid sulfite pulping processes employing metallic ions such as sodium, calcium, magnesium, to ammonia-base sulfite and alkaline sulfite pulping liquors.
