Abstract: A method of removing mercury from a process gas by means of a sorbent and a filter (10) involves applying said sorbent to at least one filtering surface (12) of the filter (10). A first parameter, which is indicative of the amount of mercury that needs to be removed in said filter (10), and a second parameter, which is indicative of the amount of material that has been collected on said filtering surface (12), are measured. A measured value of said first parameter is compared to a mercury set point. When said measured value of said first parameter is higher than said mercury set point, the cleaning of said filtering surface (12) is delayed, compared to the point in time suggested by a measured value of said second parameter.

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.
