Abstract: An apparatus and a method for driving an icemaker for making ice cubes in a refrigerator. An ice-full state is sensed in such a way as to rotate an ejector and a cam gear in a reverse direction (opposite to an ice-ejecting direction), thereby preventing interference with the ice cubes present in the icemaker and thus enabling the ice-full state to be accurately sensed. A first torsion spring is mounted to an intermediate gear with a small rotation angle ratio to allow only a minimum amount of torque to be transferred to other components such as an ice-detecting lever, thereby increasing the durability of the components and providing a precise rotation force. The axial center of rotation of a second torsion spring is defined at a position that faces the other end (the revolving end) of the ice-detecting lever, to allow a minimum moment to be substantially constantly applied.

Abstract: An NGL recovery facility for separating ethane and heavier (C2+) components from a hydrocarbon-containing feed gas stream that utilizes a single, closed-loop mixed refrigerant cycle. The vapor and liquid portions of the feed gas stream are isenthalpically flashed and the resulting expanded streams are introduced into the NGL recovery column. Optionally, a second vapor stream can be flashed and then introduced into the recovery column at the same or lower separation stage than the flashed liquid stream. As a result, the NGL recovery facility can optimize C2+ recovery with compression costs.
