0F HOUSTON, TEXAS, ASSIGNOBS TO .A CORPORATION 0F DELAWARE GAS AND LIQUID SEPARATOB Application led August 22, 1930. Serial No.l -477,010.
This invention relates to the separationof gas from liquid, such as hydrocarbon o ils, with which it is intermixed'. The invention will be fully understood from the following description taken in connection with the accompanying drawing, in which latter Fig. 1 is a longitudinal sectional view 'through a separator;
Fig. 2 is a transverse sectional view taken along the line II-II of Fig. 1;
Fig. 3 is a transverse sectional view taken along the line III-III of Fig. 1;
Fig. 4 is a side elevation of a bailie; and
Fig. 5 is a side elevation of an auxiliary baiiie. A
Referring to the drawing, reference numeral 1 desi ates a shell which is .carried in substantia y vertical position by a support 2. The shell is provided at its upper portion with an outlet opening 3 through which gas, free rom entrained liquid, is adapted to be discharged. .The shell is provided at its lower portion with a discharge opening to which is connected an outlet pipe 4 having a valve 5. Means are provided for maintaining a predetermined level of liquid in the bottom ofthe shell. The meanscomprises a container 7 which. communicates through a line 8 with the interior of the shell. below the normal level of liquid in the shell. The upper portion of container 7 communicates with the interior of the shell above the normal level of liquid in the shell by means of a line 9. A iioat 10 is disposed within the container 7 and is adapted to actuate valve 5 through a connection 11.
An assembly through which the mixture of gas and liquid is first passed is disposed in the shell. The assembly includes a tube 15 having a closed end 16. A tube 17 of relatively small diameter projects through the 4closed end 16 and terminates the larger tube to form an annular chamber 18 with a portion only of the largerftube.` Tube 17 is provided with a closed end 19 exteriorly of the larger tube and has openings 20 in its side walls intermediate its closedend 19 and the closed end 16 of the larger tube. Vanes 21 project outwardly tangentially over the openings from an edge of each opening 2O of the smaller tube 17.
The assembly is disposed in the lower portion of the shell in spaced relation to the side, walls of the shell to form an annular pas sage 23 with the side walls. The assembly is disposed in spaced'relation to the bottom of the shell and provides a reservoir for the separated liquid between the assembly and the bottom of the shell". A conduit 24 leads into the shell and'opens tangentially through: tube 15 into the upper portion of the annular chamber 18. The assembly is supported in spaced relation to the shell by means of the spacedv supports 25 and by means of the rods 26 with the open end of the annular chamber opening downwardly.
The mixture of gas and liquid is injected through conduit 24 into the upper portion of the annular chamber 18 under suliicient pressure to causevthe mixture to travel in a helical path downwardly through the annular cham'- ber at suiiicient speedto centrifugally separate the major portion of the gas and liquid. The liquid is forced to theJ radially outer portion of the annular chamber while the gases seek the radially inner portion of the annular chamber. The 'thus separated liquid falls by gravity into the reservoir at the bottom of the shell where it is permitted to accumulate to a level intermediate the open end of the larger tube 15 and the annular chamber 18. Float 10 is adjousted to maintain this level of cseparated liquid in the shell. Consequently the separated gas reverses its general direction of travel and flows upwardly through the relatively small tube 17 and is discharged from the tube through the opencarries 'some entrained liquid is greatly relarge scrubbing surface before nally passduced in passing through the enlarged zone ing out `of the separator through opening 3. and the carrying power of the gas for the By the construction described centrifugal entrained fluid is reduced toaminimum. In force is utilized for the separation of gas case the mixture of gas and liquid is introfrom a mixture of gas and liquid. The speed 70 duced into the assembly under relatively high of travel of the separated gas is then reduced pressures and the pressure of the gas forces to a minimum and thereby the carrying powthe liquid in the reservoir below the level er of the gas for entrained liquid is miniof the inner tube 15 and thus permits the gas mized. The greatest possible reversal of flow to escape from the assembly through the of the thus treated gas is then effected and a 75 annular passage 23 rather than through the maximum of scrubbing surface is presented pipe 17. In such a case, the supports 25 for to the gas. v lthe assembly function as baiiles to effect the Various changes may be made within the extraction of entrained liquid from such gas scope of the appended claims, in which it is as does pass through this annular passage. desired to claim all novelty inherent in the 80 Bailies 30 and 31 are provided in the upper invention as broadly as the prior art permits. portion of the shell at a substantial distance We claim:
