Abstract
Methods for contacting removing an odorous or noxious component from a gas stream using a scrubbing solution containing a biocide in a gas/liquid contactor are described. The biocide is used to avoid or prevent or minimize or control biological growth and fouling, particularly in the gas/liquid contactor.
Claims19
A method for removing an odorous or noxious component from a gas stream using a gas/liquid contactor, comprising:
- contacting a gas stream comprising at least one odorous or noxious component with a liquid scrubbing solution capable of absorbing the at least one odorous or noxious component, wherein said contacting occurs in a gas/liquid contactor, and wherein a recycle line recycles the liquid scrubbing solution from a sump upstream of the recycle line to the gas/liquid contactor;
- absorbing the at least one odorous or noxious component into the liquid scrubbing solution, thereby removing the at least one odorous or noxious component from the gas stream;
- adding a biocide to the scrubbing solution by adding the biocide directly to the recycle line;
- and
- maintaining a residual level of the biocide in the scrubbing solution during operation;
- whereby biological fouling is controlled in the gas/liquid contactor.

- absorbing the at least one odorous or noxious component into the liquid scrubbing solution, thereby removing the at least one odorous or noxious component from the gas stream;
- adding an amount of biocide to reduce a pre-existing amount of biological growth in the gas/liquid contactor;
- and
- adding an additional amount of biocide to the scrubbing solution after said adding an amount of biocide to reduce the pre-existing amount of biological growth
- to maintain a residual level of the biocide in the scrubbing solution during operation and thereby maintain a reduced amount of biological fouling in the gas/liquid contactor.
