Abstract
Disclosed are apparatuses and methods for transferring heat from a relatively hot stream of solid materials to a relatively cold stream of solid materials. Both streams cascade downward under the force of gravity over a series of heat pipes which are arranged between the streams to transfer heat therebetween. The heat pipes are arranged so they provide countercurrent heat transfer between the two materials streams. The invention is shown applied to a process for recovering hydrocarbons from shale rock.
