Abstract: A hydrolyzer infeed system for supplying waste material to a hydrolyzer in a continuous manner, the infeed system comprises an infeed chamber, an inlet gate separate a chamber inlet from a chamber outlet, a ram disposed to reciprocate within the infeed chamber and compress waste material against the inlet gate when the gate is in the closed position and configured to push the compressed waste material past the inlet gate into a hydrolyzer when the gate is in an open position, an actuator operably coupled to the ram and configured to move the ram between retracted and extended positions. In one aspect, the ram extends past the inlet gate when in an extended position. In another aspect, an actuator position sensor operably coupled to the actuator generates a position signal representative of a position of the actuator and a corresponding position of the ram at all positions between the retracted ram position and the extended ram position.

Abstract: A process for transforming a stream of MSW material into feedstock for an anaerobic digester and the resulting generation of biogas and other useful products includes the removal of one or more selected chlorine containing components and the retaining of substantially all paper components. At least 70% by mass of the incoming stream of MSW material is hydrolyzed and subsequently directed to the anaerobic digester.

Abstract: A hydrolyzer outfeed system includes a hydrolyzer having a hydrolyzer outlet, an intermediate pressure chamber having a pressure chamber inlet and a pressure chamber outlet, and an expansion chamber. A pressure chamber inlet valve selectively communicates the hydrolyzer outlet with the pressure chamber inlet, the inlet valve having an inlet valve cross-sectional area in a fully open position. A pressure chamber outlet valve selectively communicates the pressure chamber outlet with the expansion chamber. The pressure chamber outlet valve has an outlet valve cross-sectional area in a fully open position. The outlet valve cross-sectional area is smaller than the inlet valve cross-sectional area.

Abstract: A loan portfolio manager system is provided to predict and prioritize loans at risk of default and foreclosure. The loan portfolio manager system may analyze the loans at risk to determine which of the loans are at risk and also candidates for modification. The loan portfolio manager system may generate recommended modification solutions for those at risk loans by applying configurable criteria and data analytics. The loan portfolio manager system may monitor and report on the health of loan portfolios, borrowers, and on success of loan modifications. The loan portfolio manager system may facilitate loan modification business process outsourcing through campaign management and buyer contact/interaction capabilities.

Abstract: A hydrophilic polyol having a molecular weight of less than about 4500 and comprising ethylene oxide units and alkylene oxide units selected from propylene oxide, butylene oxide and mixtures thereof in a weight ratio of ethylene oxide units to alkylene oxide units in the range of from about 95:5 to about 60:40, the polyol having a secondary hydroxyl content of at least about 80% based on the total hydroxyl content of the polyol. A process for producing the hydrophilic polyol is also described.

Abstract: A process for recovering free aluminum and aluminum compounds such as aluminum oxide from aluminum dross and aluminum scrap in a furnace heated with a plasma arc torch wherein air at high enthalpy is used as the arc gas. The use of air at high enthalpy as the arc gas provides for more rapid heat output, causing the outer surface or shell of dross to heat rapidly, thereby rupturing the oxide shell releasing free aluminum from within the shell. A higher aluminum recovery is obtained. In a plasma torch high enthalpy is obtained by adding a gas such as CO.sub.2, methane or hydrogen to the air arc gas at a fixed current level or by operating the plasma torch with higher current at a fixed air flow.

Abstract: An assembly for the recovery of aluminum metal from aluminum dross comprising a rotary furnace, a plasma arc torch, and a supervisory control system for tying together and automatically controlling the operation of the rotary furnace and plasma arc torch is described. The invention provides recovery of aluminum metal from dross in an efficient and economical process.
