Abstract: A turbine bypass system comprises a bypass path which is selectively operable to deliver hot gases to a gas cooler and a pebble bed positioned in the bypass path upstream of the gas cooler. The pebble bed absorbs heat from the bypass gases and thereby reduces the temperature of the bypass gases prior to delivery of the bypass gases to the gas cooler.

Abstract: A rotating packed bed RPB that includes a first and second packed bed both arranged on the same rotatable shaft. A gas is directed via a gas inlet through the first packed bed in co-current flow with a liquid in a radially outward direction towards the outer radius of the packed bed. The liquid enters the first packed bed via a first liquid inlet. The gas exiting the first packed bed is directed to the second packed bed and forced through it in a radially inward direction in counter-current flow with a liquid, which enters through a second liquid inlet. The arrangement allows an operation of the rotating packed bed with less energy compared to RPBs of the prior art operating in counter-current flow only. The apparatus allows low-cost design and high design flexibility.
