Abstract:
A gas-solids reaction system with termination devices to connect a riser with one or more separation devices. The termination devices have a radius of curvature that is at least 1.0 times as great as the diameter of the conduit forming the termination device. The termination devices can be openly or closely coupled to the separation devices.
