INVENTOR. LOU/S 7. COPE BY Z AGENT United States Patent Office 3,234,746 Patented Feb. 15, 1966 3,234,746 PROCESS AND APPARATUS FOR THE TRANSFER OF LIQUID CARBON DIOXIDE Louis T. Cope, Chattanooga, Tenn., assignor to Olin Mathieson Chemical Corporation Filed Apr. 28, 1964, Ser. No. 363,255 6 Claims. (CI. 62-55) This invention relates to a method and apparatus for the transfer of liquid carbon dioxide from a storage container to a second container, the carbon dioxide in the storage container having a maximum temperature of 10 F. and a maximum pressure of 350 p.s.i.g.

Carbon dioxide is commonly stored in bulk storage plants throughout the country under a pressure usually in the range of from 280 to 305 p.s.i.g. and at a tempera ture of about F. The containers are insulated and refrigerated to maintain these conditions. Various pumps are known to the art for the purpose of transferring liquid carbon dioxide from such storage containers to smaller containers usually ranging from to 150 pounds. The prior devices require a source of power, usually an electrically operated pump, and may cost from $1500 to $2000. The methods and apparatus of this invention provide a system for the transfer of liquid carbon dioxide using a compressed gas as motive power. Preferably, it is the gaseous carbon dioxide from the same storage container as the liquid carbon dioxide. The process of this invention requires a minimum gas pressure of 150 p.s.i.g. Pressures up to about 300 p.s.i.g. are ordinarily available in such storage containers. Alternatively, compressed air or steam, either of which is usually available from any conventional source, are suitable motive fluids. The system provided by this invention is simple, filling is rapid and the cost of the apparatus at present market prices is about $200.

The apparatus consists primarily of a double acting duplex pump with suitable fittings. The pump consists of two pistons and cylinders with a common piston rod. The motive piston and cylinder have a larger diameter than that of the driven piston and cylinder in order to utilize gaseous carbon dioxide from the storage container as the motive power under the same available pressure as the liquid to be moved. In a particularly advantageous form of the invention the diameter of the motive cylinder is 3 to 3 /2 and that of the driven piston cylinder is about 1 /2". The cylinders may be constructed of any suitable material, for example, brass or steel. A steel cylinder having a brass lining is especially suitable. The driven piston is composed of a heavy Teflon plate suitably to l in thickness faced by aluminum plates A to A" in thickness. The driven piston can be similarly constructed or it may be of steel with steel piston rings or other material suitable for use with the motive fluid.

At substantially the mid-point of the piston rod, a cam is provided for operating the reversing valve which delivers motive fluid alternately to the top and the bottom of the cylinder for the driving piston. The cam actuates upper and lower control followers at the upper and lower ends of the stroke controlling the flow of actuating fluid, conveniently the same as the motive fluid, to effect operation of the reversing valve. The cam can be attached to the piston rod or to separate piston rods in any suitable manner, for example, it can be a standard shaft collar, held in place by one or more set screws.

Liquid carbon dioxide is supplied through check valves to the upper and lower ends of the cylinder containing the driven piston. Exit conduits are provided from the top and bottom of the same cylinder. Check valves in the exit conduits prevent back flow of the liquid carbon dioxide into the cylinder. The exit conduits are joined in a common delivery conduit. A bypass around the pump is provided from the liquid carbon dioxide supply line to the delivery line since the receiving cylinder can be quickly and partially filled with liquid without operating the pump. When the flow through the by-pass diminishes, the pump is started by admitting the motive and actuating fluids to the reversing valve. Suitable safety discs and gauges are also provided in the delivery line.

Although, for simplicity and convenience, reference herein is made to upper and lower parts and upward and downward strokes and although the figure shows the pump of this invention in a particular position, nevertheless the process of this invention can be operated with the pump in an inverted or any other position, the relation of each part to each other part being the same.

The figure shows a system according to the present invention for transferring liquid carbon dioxide from supply container 11 to receiving container 12. In the pump, shaft 13 is connected at one end to driving piston 14 contained in cylinder 15. At the opposite end of shaft 13 is driven piston 16 in cylinder 17. At about the mid-point of shaft 13 is cam 18. At the upper end of the stroke, cam 18 engages and moves upper control follower 19 and at the lower end of the stroke lower control follower 20. Each of the cam-followers is spring loaded and suitably stopped so that it always returns to a position of rest. Actuating fluid is supplied via conduit 21 controlled by control follower 19 through line 23 to reversing valve 25. Similarly actuating fluid is supplied. via line 22 controlled by lower control follower 20 via line 24 to reversing valve 25. Motive fluid to reversing valve 25 via line 26 and exhaust conduit 27 is supplied to reversing valve 25. The motive fluid flows via line 28 and 29 to the upper and lower ends respectively of cylinder 15. Motive fluid is supplied from supply container 11 via line 30 controlled by valve 31. Alternatively, any other motive fluid can be supplied via line 32 controlled by valve 33. Conduit 34 is the liquid carbon dioxide supply conduit controlled by valve 35. This line is divided into lines 36 and 37 controlled by check valves 38 and 3 9 respectively to cylinder 17. Conduits 40 and 41 are respectively the upper and lower liquid carbon dioxide delivery conduits controlled by check valves 42 and 43. Conduit 40 and 41 combine in common conduit 44. Liquid carbon dioxide is delivered through conduit 44 controlled by check valve 45 and supply container valve 46 to receiving container 12. By-pass line 47 controlled by check valve 48 is provided for direct transfer of liquid carbon dioxide from supply container 11 to receiving container 12. Conduit 49 leads from conduit 40 to safety disc 50 and gauge 51.

In operation cylinder 17 is flooded with liquid carbon dioxide, valve 31 is opened to supply gaseous carbon dioxide as actuating fluid and motive fluid through reversing valve 25 alternately to the top and bottom of cylinder 15. On the upward stroke cam 18 contacts follower 19 moving it to supply actuating fluid via line 23 to valve 25 reversing the flow of motive fluid from line 29 to line 28. On the downward stroke cam 18 contacts and moves lower follower 20 supplying actuating fluid via line 24 to valve 25 reversing the fllow of motive fluid from line 28 to 29. On the upward stroke liquid carbon dioxide is supplied via line 37 to the underside of piston 16 while carbon dioxide is transferred from the upper side of piston 16 via line 40 and 44 to receiving cylinder 12. On the downward stroke liquid carbon dioxide is supplied via line 36 to the upper side of piston 16 while liquid carbon dioxide is transferred from the lower side of piston 16 via line 41 and 44 to receiving cylinder 12. The operation is initiated by transferring liquid carbon dioxide via by-pass 47 to cylinder 12 until the flow diminishes.

Example In a pump and transfer system according to the pres ent invention, an upper and lower cylinder were formed of steel having a brass liner. The top cylinder was 1%" in internal diameter and the lower cylinder 3 /2" in diameter. A cam was attached at the center of a 12 iston rod and a /2" thick Teflon head faced on each side by a As" thick sheet of aluminum was bolted to one end of the piston rod to form the driven piston. The driving piston was a 3 /2 diameter standard steel piston fitted with suitable piston rings and connected to the opposite end of the piston rod. The lower end of the upper cylinder and the upper end of the lower cylinder were closed by packing nuts around the shaft. The packing nuts were lined internally with Teflon sleeve packing. Two diametrically opposite holes were tapped and threaded near the top of the upper cylinder for inlet and exit conduits. Similarly inlet and exit conduits were provided at the bottom of the upper cylinder. Check valves were installed in the upper and lower inlet lines to the upper cylinder and the two lines were in turn connected to the supply container of carbon dioxide. It provided liquid carbon dioxide to the driven piston and gaseous carbon dioxide to the driving piston at a pressure of 300 p.s.i.g. and a temperature of F. The two exit openings of the upper cylinder were provided with check valves to prevent back flow and these exit lines were combined in a delivery conduit to the container to be filled. A by-pass line was provided directly from the inlet conduit to the delivery conduit. Suitable safety discs and gauges were installed in the delivery conduit. A reversing valve was connected to the gaseous supply of carbon dioxide in the storage container and to upper and lower exit conduits in the lower cylinder. The reversing valve was actuated by cam followers located near each end of the stroke of the cam. The cam follower actuated by the came in turn reversed the reversing valve and the flow of motive fluid was directed to the opposite end of the driving cylinder.

The first of several small cylinders to be filled was connected to the delivery conduit, the cylinder valve Was opened and the delivery conduit was opened. The by-pass line was opened and the receiving cylinder was partially filled with liquid. The gaseous carbon dioxide conduit to the reversing valve was then opened starting the pump. In about 1 /2 minutes the pound cylinder was substantially filled with liquid carbon dioxide. The delivery conduit valve and the cylinder valve were closed and the cylinder disconnected. Additional cylinders were similarly filled.
