Definitions
- Another object of this invention is to provide a gasliquid contact apparatus Which will operate over long periods of time without surges.
- Still another object of this invention is to provide a gasliquid contact apparatus which is simple and inexpensive to construct.
- FIGURE 1 is a side sectional view of a device embodying the present invention.
- FIGURE 2 is an erdarged partial sectional view showing the contact and separation sections of the device shown in FIGURE 1, illustrating the principle of operation.
- FIGURES 1 and 2 there is shown in FIGURES 1 and 2 a capillary tube 3 for the introduction of a gas and a second capillary tube 5 at right angles thereto for the introduction of a liquid.
- the two tubes merge into a contact section 7 and then empty into a se aration section 9.
- a side arm 11 Leading from the separation section 9 is a side arm 11 for the removal of a portion of the liquid having gas dissolved therein while the bottom of the separating section leads to an enlarged tube 13 for the removal of any gas which did not dissolve in the liquid as well as any portion of the liquid which is not removed through the side arm 11.
- top portion of the separating section 9 is flared as at 15, the purpose of which will be later explained.
- the side arm 11 leads to a measuring cell 17 having electrodes 19 and 21 making conductivity measurements.
- the entrance section 5 may have a rotameter 23 for measuring the flow of the in-coming liquid.
- the liquid does not flow into the center as at 31 as the result of the flared entrance so that a single, stationary bubble of gas forms in the separating section.
- Liquid 29 surrounding this bubble of gas can flow out through the tube 11 as at 33 and any liquid which does not follow this path continues to flow down the walls as at 35; any liquid which is not taken off through the tube 11 flows out of the apparatus through the tub 13 While any gas which has not dissolved in the liquid flows out through the tube 13 through the center thereof.
- the capillary tubes employed can be from 0.1 to 1 mm. in inside diameter.
- the gas entry tube 3 and the contact tube 7 have a larger diameter than the tube 5 for the introduction of liquid.
- the length of the co-current contact section 7 should be 10 to 10 times the diameter in order to get good contact between the gas and liquid phases. The desired length depends on the aihnity of the impurity in the gas stream for the liquid phase. Hydrochloric acid can be quantitatively transfe-rred into water in a very short contractor section while carbon dioxide requires a very loiig contactor for equilibration.
- the combination shown in FIGURES 1 and 2 may be used for the detection of traces of HCl, S0 S0 N0 CO and other acids or acid anhydrides as well as bases in a gas stream if water or any other suitable solvent for ionization of acids, bases and salts is used as the liquid fed into the liquid inlet.
- This detector has been used for the detection of nanogram amounts of certain chlorineand also certain sulfurand also certain nitrogen-containing organic chemicals that have been eluted from a gas chromatography column, combusted with oxygen (or air) and fed into the detector as the gas stream entering the gas inlet capillary.
- a gas-liquid contact apparatus comprising combination:
