  Eductors for Pumping Gases
This fluid is then carried on through a secondary cham­ber where the friction between the molecules of it and a secondary gas (generally referred to as the suction fluid) causes this secondary gas to be pumped.
The friction between the fluids at the interface of the motive fluid causes the chamber to be evacuated as the gas in the chamber is removed.
As the motive fluid entrains the suction gas, part of the kinetic energy of the motive fluid is imparted to the suction gas.

 Gas Locked Pumps
Expanding gas bubbles "tickle" the balls and seats (valves), and the well comes to equilibrium pumping at very low efficiency and with an elevated fluid level.
The cure for Type 1 gas lock is to use either a snubber cage or a backpressure valve.
In a Type 2 gas lock, the peak pressure of the trapped gas on the downstroke is insufficient to overcome the hydrostatic head on the traveling valve.

 Gas Lasers
The helium gas in the laser tube provides the pumping medium to attain the necessary population inversion for laser action.
Operating in a manner similar to the helium-neon laser, it employs an electric discharge for pumping, using a percentage of nitrogen gas as a pumping gas.
Operating at much higher powers than the helium-neon gas laser, it is not uncommon to achieve 30 to 100 watts of continuous power using several transitions.

 MICRO:February 1998:Process Equipment—Vacuum Pumps; by Tadahiro Ohmi, (p 53)
In order to improve the TMP performance under high gas flow, a characteristic dimension in the pump, particularly at the entrance (such as the distance between each blade vane or the distance between the rotor blade and the stator blade), was shortened to increase Knudsen's number.
The new TMP was developed by shortening the characteristic distances in the pump, particularly at the entrance—such as the distance of each blade vane and the distance between the rotor blade and the stator blade—to maintain the molecular flow at higher pressures.
Experimental measurements were taken of the impurity levels in the chamber caused by the back-diffusion of impurities from the gas pumping system and the impurity compression ratio under a high gas flow.

 SitNews - Pumping Gas By Michael Reagan
Gas prices at the pump are not going to drop significantly in the foreseeable future, no matter what Congress or federal and state governments do.
Sure, they can lower their take on a gallon of gas, which, as I pointed out last week in my column, is an average of 45 to 46 cents.
Despite the spurious claims of price gouging by the wicked oil barons or OPEC or your corner gas station, the reason for the present high price of gasoline is simply this: there are too many people consuming gas supplies and too little gas to meet the need.

The pipeline, along with another carrying gas from Iran, has also drawn criticism from the US which backs a rival project to carry natural gas across from the Caspian Sea to Turkey.
The 1,393-km pipeline runs from the southern Russian gas plant of Izobilnoy under the sea to Samsun and then to the capital Ankara.
Turkey was originally to purchase 8 bn cm of gas a year via the Blue Stream link, but earlier this year was forced to ask Russia for a reduction of both the amount and the price following a severe economic crisis.

 Baker Hughes Centrilift - Gas Separator   (Site not responding. Last check: 2007-10-13)
Centrilift introduced the first rotary gas separator for oilfield applications in 1978 and Centrilift gas separators are the perfect complement to the down-hole pump when large amounts of gas must to be separated from the well fluid before it enters the pump.
Centrilift manufactures two distinct types of gas separators: The rotary chamber type, which separates gaseous and liquid phases through pure centrifugal force, and the vortex chamber type in which centrifugal force in a vortex achieves separation of gassy fluids.
The use of the gas separator increases drawdown capabilities of ESP systems and provides additional separation of entrained gas in the well fluids.

 Cell phones have caused explosions at gas stations-Fiction!
In August of 1999, David Rudd, a spokesman for Motorola, told the San Francisco Chronicle that his company's warning was because of the remote possibility that a dislodged battery cause cause a spark, not because of the transmission of radio signals.
Portable phones have been banned at gas stations in parts of Europe for many years, but Nokia spokesperson Megan Matthews told the Associated press on Jan 14, 1999 that those rules were from a bygone era when portable phones were more powerful than modern phones and that the bans were rarely enforced.
The threat mobile phones pose to gas stations and their users is primarily the result of their ability to produce sparks that can be generated by the high-powered battery inside the phone.

 2003 - Stay Outside While Pumping Gas
TALLAHASSEE – Florida Agriculture and Consumer Services Commissioner Charles H. Bronson today urged motorists to avoid a potential fire hazard at the gas pump by remaining outside the vehicle until refueling is completed.
While pumping gas remains a generally safe activity, static electricity, which is especially prevalent in Florida during dry winter months, can ignite gasoline vapors and trigger a fire.
The primary way to avoid the problem is to stay outside during refueling, so you do not come in contact with the vehicle's interior carpeting, which transfers static electricity to the motorist who must then go outside to remove the nozzle from the vehicle.
