Abstract
Implementations disclosed herein provide a dry chemical scrubber with a pH regulator that adjusts an internal pH value of the dry chemical scrubber by adding high pH elements to the contents of the dry chemical scrubber on a continuous or periodic basis.
Claims20
A gas treatment system comprising:
- a dry chemical scrubber configured to hold media therein to remove acid gas from an incoming gaseous fluid stream;
- and
- a passive pH regulator comprising high pH elements operably connected to the dry chemical scrubber, the passive pH regulator regulating pH of content within the dry chemical scrubber.
A gas treatment system comprising:
- a dry chemical scrubber having an internal volume with media therein, the media configured to react with acid gas;
- a gaseous fluid stream input into the scrubber in fluid communication with the media;
- a liquid input into the scrubber in fluid communication with the media;
- a gaseous fluid stream output from the scrubber downstream of the media;
- a liquid output from the scrubber;
- a recirculation line connecting the liquid output to the liquid input;
- and
- a pH regulator operably connected to the internal volume of the dry chemical scrubber that passively adjusts pH of content within the dry chemical scrubber.
5 more elements
A method comprising:
- receiving an input gas stream in a dry chemical scrubber configured to hold media to remove acid gas from the input gas stream,
- receiving a water source in the dry chemical scrubber;
- adjusting a pH level of one or both of the input gas stream and the water source with a pH regulator;
- and
- after adjusting the pH level, reacting the acid gas with the media.
2 more elements
A method comprising:
- receiving an input gas stream at a dry chemical scrubber configured to hold media to remove acid gas from the input gas stream, the dry chemical scrubber including at least two media layers, each of the at least two media layers separated from one another by a plenum layer;
- and
- distributing high pH elements through each of at least two distribution ports, each distribution port dispensing the high pH elements into a different one of the at least two media layers.
