| 摘要 |
The present invention relates to a method of cleaning a process gas containing sulphur dioxide, comprising removing sulphur dioxide from the process gas by contacting the process gas with seawater to generate an at least partly cleaned process gas in a first gas cleaning device. In a second gas cleaning device, being arranged in direct fluid connection with the first gas cleaning device, the at least partly cleaned process gas having passed through the first gas cleaning device is cooled to condense water there from, thereby generating a process gas having a reduced content of water vapour. At least a part of the condensed water generated in the second gas cleaning device is passed to the first gas cleaning device. The present invention moreover relates to a gas cleaning system for cleaning of a process gas containing sulphur dioxide. |
