METHOD FOR MONITORING A CLEANING OF A PROCESS GAS
First Claim
1. A method for cleaning and for monitoring a cleaning of a process gas passing through a wet scrubber, the wet scrubber comprising an inlet zone, a contact zone and an outlet zone, the contact zone divided into at least two sections, the process gas flowing through the inlet zone and into the contact zone for mixing with an absorption liquid within the wet scrubber, the absorption liquid absorbing at least part of a sulphur dioxide content of the process gas, the process gas then flowing out of the wet scrubber via the outlet zone, the method comprising:
- measuring a concentration of sulphur dioxide in at least a first measuring point corresponding to a first section of the at least two sections of the contact zone to obtain measurement information; and
comparing the measurement information to a reference value for determining a local sulphur dioxide removal performance of the first section.

Abstract
The present disclosure is directed to a method for monitoring a cleaning of a process gas passing through a wet scrubber. The wet scrubber comprises an inlet zone, a contact zone and an outlet zone. The contact zone is divided into at least two sections. The method comprises measuring a concentration of sulphur dioxide in at least a first measuring point corresponding to a first section of the at least two sections of the contact zone to obtain measurement information; and comparing the measurement information to a reference value to determine a local sulphur dioxide removal performance of the first section.

17. A gas cleaning system for cleaning a process gas, comprising:
-
a wet scrubber for separating sulphur dioxide from the process gas passing through the wet scrubber by contact with an absorption liquid within a contact zone within the wet scrubber; at least one sulphur dioxide detecting sensor; and at least a first measuring point;
whereinthe first measuring point corresponds to a first section of at least two sections of the contact zone, and the at least one sulphur dioxide detecting sensor is operable to measure a concentration of sulphur dioxide in the first measuring point to obtain measurement information to determine a local sulphur dioxide removal performance of the first section. - View Dependent Claims (18, 19, 20, 21)
