ABSTRACT:
Gas-solids transport and heat exchange techniques are disclosed wherein solid particulate material is circulated in a "figure 8" or a circular flow path for selective contact and/or direct heat exchange with gaseous media. The particulate material is introduced into streams of gaseous media at spaced locations in the flow path and subsequently separated from the gaseous streams following contact and/or heat exchange therewith. The gaseous streams are maintained separate from one another by loose packed bed columns of particulate material formed in the flow path and used to introduce the particulate material into the gaseous streams. The flow rate of the particulate material is regulated by the controlled biasing of particulate material from each of the columns thereof directly into the gaseous streams, and the particulate material is circulated solely through the use of the gaseous media and the force of gravity. The particulate material is circulated in cocurrent relationship with each of the gaseous streams in figure 8 flow path systems and, in circular flow path systems, the particulate material is circulated in cocurrent relationship with one of the gaseous streams and in countercurrent relationship with the other of the gaseous streams. In heat exchange applications, heat transfer between the streams of gaseous media is provided as a function of the flow rate of the particulate material and the relative flow rates of the streams of gaseous media.
