2. Drum pump - Wikipedia

   en.wikipedia.org/wiki/Drum_pump

   Drum pump, barrel pump, and transfer pump refer to pumps that are used to empty barrels, tanks, IBCs and drums. [1] Many liquids used on manufacturing and processing plants are delivered in 100 or 200 litre barrels and are too heavy to tip to empty the liquids inside. Drum pumps range from simple siphon based devices to sophisticated highly ...

3. Vacuum truck - Wikipedia

   en.wikipedia.org/wiki/Vacuum_truck

   A vacuum truck, vacuum tanker, vactor truck, vactor, vac-con truck, vac-con is a tank truck that has a pump and a tank. The pump is designed to pneumatically suck liquids, sludges, slurries, or the like from a location (often underground) into the tank of the truck. The objective is to enable transport of the liquid material via road to another ...

   Pressure in blanketed tanks is maintained by self actuating pressure control valves (PCVs). As liquid is withdrawn from the tank the pressure in the gas space falls. The blanket gas supply valve opens to maintain the pressure. As the tank fills with liquid the pressure rises and a vent gas valve open to vent gas to atmosphere or a vent system. [11]

5. Separator (oil production) - Wikipedia

   The sizing methods by K factor and retention time give proper separator sizes. According to Song et al (2010), [3] engineers sometimes need further information for the design conditions of downstream equipment, i.e., liquid loading for the mist extractor, water content for the crude dehydrator/desalter or oil content for the water treatment.

   On average, it costs between US$10-$15 per barrel to transport oil and gas by rail compared to $5 a barrel for pipeline. [ 23 ] [ 24 ] In 2012,16 million barrels of oil were imported to USA by rail. By 2014, that number increased to 59 million barrels. [ 25 ]

7. Fluid power - Wikipedia

   en.wikipedia.org/wiki/Fluid_power

   A fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) that converts mechanical energy into fluid energy, Pressurized fluid is controlled and directed by valves into an actuator device such as a hydraulic cylinder or pneumatic cylinder, to provide linear motion, or a hydraulic motor or pneumatic motor, to provide rotary motion or torque.
