## Abstract

The present disclosure describes a contactor device which may include a housing including a tank and a lid, wherein there is a seal between the tank and the lid, at least one liquid inlet, at least one gas inlet, a bed of a contact medium contained within the tank and positioned over a barrier having a plurality of through holes, at least one liquid outlet, at least one gas outlet, and a guide plate positioned to prevent the liquid from reaching the gas outlet. Methods of operating a contactor device are also described and may include methods of capturing and converting carbon dioxide to commercially useful materials.

## Claims

### Claim 1

A contactor device, comprising:
a furnace comprising a housing and having an insulation layer surrounding the furnace,
the housing comprising a tank and a lid, wherein there is a seal between the tank and the lid,
at least one liquid inlet,
at least one gas inlet,
a bed of a contact medium contained within the tank and positioned over a barrier having a plurality of through holes,
at least one liquid outlet, and
at least one gas outlet.

### Claim 2 (depends on 1)

The contactor device of claim 1, wherein the seal comprises a flange.

### Claim 3 (depends on 1)

The contactor device of claim 1, wherein the seal is welded.

### Claim 4 (depends on 1)

The contactor device of claim 1, wherein the seal comprises an ultra-high vacuum gasket.

### Claim 5 (depends on 1)

The contactor device of claim 1, further comprising a guide plate positioned to prevent the liquid from reaching the gas outlet.

### Claim 6 (depends on 1)

The contactor device of claim 1, wherein the at least one liquid inlet, the at least one gas inlet, the at least one liquid outlet, and the at least one gas outlet are each connected to the housing with a flange.

### Claim 7 (depends on 6)

The contactor device of claim 6, wherein the flanges connecting the least one liquid inlet and the at least one liquid outlet to the housing further comprise a gasket.

### Claim 8 (depends on 7)

The contactor device of claim 7, wherein the gasket comprises graphite and an alloy.

### Claim 9 (depends on 1)

The contactor device of claim 1, wherein the at least one liquid inlet comprises a sprayer.

### Claim 10 (depends on 1)

The contactor device of claim 1, wherein the contact medium comprises a ceramic material.

### Claim 11 (depends on 1)

The contactor device of claim 1, wherein the contact medium comprises Raschig rings, Pall rings, berl saddles, or combinations thereof.

### Claim 12 (depends on 1)

The contactor device of claim 1, wherein the tank has a height-to-width ratio of about 1:1 to about 25:1.

### Claim 13 (depends on 1)

The contactor device of claim 1, wherein the contactor device does not include a valve.

### Claim 14 (depends on 1)

The contactor device of claim 1, wherein the at least one liquid inlet and the at least one gas inlet are connected to an upper portion of the housing, and wherein the at least one liquid outlet and the at least one gas outlet are connected to a bottom portion of the housing.

### Claim 15 (depends on 1)

The contactor device of claim 1, further comprising a system for measuring the concentration of carbon dioxide at the at least one gas inlet, the at least one gas outlet, or a combination thereof.

### Claim 16 (depends on 1)

A method of operating the contactor device of claim 1, comprising:
directing a liquid through the at least one liquid inlet and directing a gas through the at least one gas inlet,
contacting the liquid with the gas, and
collecting the liquid from the at least one liquid outlet and collecting the gas from the at least one gas outlet.

### Claim 17 (depends on 16)

The method of claim 16, wherein the liquid comprises a molten salt.

### Claim 18 (depends on 16)

The method of claim 16, wherein the liquid comprises lithium.

### Claim 19 (depends on 16)

The method of claim 16, wherein the liquid comprises lithium carbonate and lithium oxide.

### Claim 20 (depends on 16)

The method of claim 16, wherein the liquid comprises at least about 0.1 molal lithium oxide in lithium carbonate.

### Claim 21 (depends on 16)

The method of claim 16, wherein the liquid is at a temperature of about 650° C. to about 850° C. prior to being directed through the at least one liquid inlet.

### Claim 22 (depends on 16)

The method of claim 16, wherein the gas is at a temperature of about 25° C. to about 650° C. prior to being directed through the at least one gas inlet.

### Claim 23 (depends on 16)

### Claim 24 (depends on 16)

The method of claim 16, wherein the gas comprises carbon dioxide, and wherein contacting the liquid with the gas initiates a chemical reaction.

### Claim 25 (depends on 16)

The method of claim 16, wherein the gas comprises carbon dioxide, and wherein contacting the liquid with the gas comprises removing carbon dioxide from the gas.

### Claim 26 (depends on 16)

The method of claim 16, wherein the contactor device is operated continuously.

### Claim 27 (depends on 16)

The method of claim 16, further comprising measuring the concentration of carbon dioxide at the at least one gas inlet, the at least one gas outlet, or a combination thereof.

### Claim 28 (depends on 16)

The method of claim 16, further comprising measuring the reaction of carbon dioxide with lithium oxide to form lithium carbonate.
