Abstract
The use of a turbulent contactor to absorb a selected gas component from a gas stream. The invention particularly applies to a method of distributing a liquid into a gas stream which comprises providing a liquid to an annulus at the periphery of a pipe in which a gas stream is flowing, the gas flow drawing the liquid into a film along the inner surface of the pipe to a sharp edge at the end of the pipe at which point the liquid breaks off the surface of the pipe and mixes intimately with the gas.
Claims27
A method of distributing a liquid into a gas stream which comprises providing a liquid to an annulus at the periphery of a pipe in which a gas stream is flowing, the gas flow drawing the liquid into a film along the inner surface of the pipe to a sharp edge at the end of the pipe at which point the liquid breaks off the surface of the pipe and mixes intimately with the gas.
A method as claimed in any preceding claim, in which the pipe section upstream from the reaction zone in which the gas stream is flowing is a converging pipe section which accelerates the gas as it passes the annulus of liquid.
A method as claimed in any preceding claim, in which the method further includes the step of separating a gas phase and a liquid phase after the turbulent mixing.
A method as claimed in any preceding claim, in which the gas stream is a mixture from which one or more selected components are removed using one or more solvents or reagents.
A method as claimed in any preceding claim, in which there is a diverging section of pipe after the reaction zone to expand the gas.
A method as claimed in any preceding claim, in which a second contactor is placed in series with the first.
Apparatus for distributing a liquid into a gas stream comprising a turbulent contactor having a contracting pipe section through which a gas stream flows, a liquid inlet arranged to produce an annulus of liquid around the internal perimeter of the pipe, a sharp edge at the end of the contracting pipe and a further pipe section downstream of the sharp edge.
