Abstract: The present invention relates to a process and contactor vessel in which gas and liquid contact occurs to facilitate mass transfer therebetween. In one embodiment, the process includes a fluidised bed including mobile inert primary objects and secondary particles that facilitate turbulent mixing and enhanced gas/liquid surface area in the contactor.

Abstract: The invention relates to a method adapted for integration with a carbonate absorption/stripping process for removal of carbon dioxide, the method and system including the steps of: converting a source of alkali from a first industry to a non-carbonate alkali; feeding the non-carbonate alkali as makeup to a carbonate absorption system for stripping carbon dioxide from emissions from a second industry; recovering an output from the system for stripping carbon dioxide, and in the process of conversion of the alkali from the first industry, utilising energy from the second industry.
