A plural stage subatmospheric water deoxygenator of the type wherein oxygen-containing water charged through a water feedline is sprayed into a vacuum chamber for the removal of oxygen therefrom which also includes first stage vacuum chamber means including first stage scheduling means for simultaneously and continuously: 1. Spraying charged pressured feedwater into the first stage vacuum chamber to initiate the removal of oxygen therefrom and 2. Adjusting the rate of flow of feed water to and t...

A degasser for removing contaminating gases from an aqueous fluid including a motor having a depending drive shaft, a hollow gear box casing having a lubricant inlet port formed therein adjacent the top thereof, a reduction gear arrangement comprising a stationary ring gear fixed to said gear box casing below said inlet port; the ring gear arrangement including a ring gear having a lubricant outlet port formed therein in a groove between two of the teeth, a plurality of reduction gears operative...

A spinner for rotating a pipe, such as a spinner mandrel, including a chambered frame having aligned openings through which the pipe can be inserted, drive assembly, such as a sprocket, rotatably mounted in the chamber, endless flexible spinning member, such as a multistrand roller chain, normally slackly encircling the pipe and the drive assembly, and clutch assembly, such as an idler sprocket in engagement with the multistrand roller chain and a hydraulically actuatable piston for laterally mo...

A modified drilling mud degasser is used to simultaneously degas drilling mud delivered thereto from a mud tank and to supercharge a mud pump to which the degassed mud is delivered. This is accomplished through the provision of a drilling mud degasser and supercharger comprising power driven degassing means for removing gas from drilling mud delivered thereto and pump means for delivering degassed drilling mud therefrom to said mud pump at a predetermined pump supercharging pressure, and means f...

A heat recovery system for at least partially cooling and at least partially cleaning an exhaust stream of hot air from a heating operation which is contaminated with vaporized, condensable liquids and with finely divided particulate solids comprising (a) a first indirect heat exchange means for partially cooling the hot exhaust stream with a fresh stream of cold air to a temperature not significantly above the dew point of vaporized liquids entrained in the hot air stream and for partially heat...

Methane-rich synthesis gas comprising H.sub.2, CO, CO.sub.2 and 10 to 26 percent by volume of CH.sub.4 (dry basis) is produced by the partial oxidation of a hydrocarbonaceous fuel in a free flow noncatalytic synthesis gas generator at a reaction temperature below 1,700.degree.F., a pressure in the range of about 15 to 250 atmospheres, and a steam of fuel weight ratio in the range of about 3 to 5. The product gas, after removal of CO.sub.2 and H.sub.2 S has a heating value in excess of 400 BTU/SC...

Run-away sulfuric acid of less than catalytic strength (88 percent), or the entire reaction mixture containing such acid, is charged to a normally operating alkylation reaction, and the acid is thus restored to alkylation strength. The alkyl sulfate which would contaminate the alkylate product of a run-away acid is thus alkylated resulting in a sulfur-free alkylate.

An extractive distillation agent used for the distillation of propylene oxide contaminated with water, acetone, acetaldehyde and methanol and consisting essentially of ethylene glycol monomethyl ether is fed to an extractive distillation column within about 2 to about 15 stages from the top of the tower to obtain an overhead distillate fraction consisting of essentially anhydrous propylene oxide contaminated with reduced quantities of acetone, acetaldehyde and methanol, and a heavier bottoms dis...

A water-containing fuel boiling in the gasoline boiling range, such as gasoline or gasohol, is contacted with a substantially saturated aqueous solution of potassium fluoride (or carbonate) plus solid potassium fluoride (or carbonate) and dry fuel is recovered.
