Abstract
Techniques for drift elimination in a liquid-gas contactor system include configuring a pre-fabricated mechanical frame coupled to a drift eliminator material to produce a framed drift eliminator assembly with substantially no air gaps between the drift eliminator material and the pre-fabricated mechanical frame, and coupling the framed drift eliminator assembly to the liquid-gas contactor system.
Claims23
A dual-cell cross flow gas contactor for capturing atmospheric CO2, the dual-cell cross flow gas contactor comprising:
- an induced fan within a fan cowling, the induced fan coupled to a structural housing;
- one or more sections of drift eliminator material comprising outer edges, the outer edges sealed to the structural housing to fill gaps between the one or more sections of drift eliminator and the structural housing;
- one or more sections of packing material coupled to the structural housing and having an air travel depth between 4 meters and 9 meters defined between a packing inlet and a packing outlet, the one or more sections of packing material including a first section and a second section spaced apart from the first section, the one or more sections of packing material configured to be wetted by a process solution having a CO2-absorbing capacity;
- an open plenum section within the structural housing and defined between the packing outlet of the one or more sections of packing material and the fan cowling;
- a basin configured to collect the process solution from the one or more sections of packing material;
- and
- piping fluidly coupling the basin to the one or more sections of packing material, the piping configured to redistribute at least a portion of the process solution collected in the basin from the one or more sections of packing material directly back to the one or more sections of packing material.

A dual-cell cross flow gas contactor for capturing atmospheric CO2, the dual-cell cross flow gas contactor comprising:
- a structural housing;
- a fan cowling extending upwardly from a fan cowling inlet adjacent the structural housing to a fan cowling outlet;
- at least one induced fan vertically positioned within the fan cowling between the fan cowling inlet and the fan cowling outlet and coupled to the structural housing;
- a first cell and a second cell, each of the first cell and the second cell comprising:
- an air inlet;
- and
- a packing material positioned within the structural housing lower than the at least one induced fan, the packing material having an air travel depth between 4 meters and 9 meters defined between a packing inlet and a packing outlet, the packing material configured to be wetted by a process solution having a CO2-absorbing capacity;
- a plenum between the first cell and the second cell, the plenum defined between the packing outlet of each of the first cell and the second cell and between the fan cowling, the at least one induced fan configured to rotate about an upright fan axis to create an air flow through the air inlet of the first cell and the air inlet of the second cell, through the packing material of the first cell and the packing material of the second cell, through the plenum, and through the fan cowling outlet;
- at least one drift eliminator positioned within the structural housing lower than the at least one induced fan, the at least one drift eliminator positioned downwind of the packing material of the first cell and of the second cell and upwind of the at least one induced fan relative to a direction of the air flow, the at least one drift eliminator comprising outer edges sealed to the structural housing to fill gaps between the at least one drift eliminator and the structural housing;
- at least one basin being positioned below the packing material of the first cell and the packing material of the second cell to collect the process solution from the packing material of the first cell and the packing material of the second cell;
- one or more flow pipes fluidly coupling the at least one basin to the packing material of the first cell and the packing material of the second cell;
- and
- a pump fluidly coupled to the at least one basin and configured to redistribute at least a portion of the process solution collected in the basin from the packing material of the first cell and the packing material of the second cell directly back to the packing material of the first cell and the packing material of the second cell.
