Oil and Gas industry works on its capability of transferring fluids and gases from one location to another, and pumps play a vital role in this. This is why refineries cannot operate without pumps.
To satiate the pumping needs of the oil and gas industry pumps come in different types depending on different requirements. Let’s explore some common pumps that are used in oil and gas downstream operations.
These pumps use a rotating impeller to create a vacuum for fluid movements. Due to its design, the centrifugal pump can be used for a wide range of applications and is preferred to handle low viscosity liquids and high flow rates. Centrifugal pumps are also used in the upstream oil and gas industry as a multiphase pumping application. These pumps are of different types like electric submersible pumps that are used as a water and oil separator. They can also transport a significant amount of low viscosity liquids in a short period and can pump several hundred gallons of liquid per minute.
Booster pumps are widely used in the oil and gas industry for different purposes. These pumps are of different types and can be used with both liquid and gas. Construction details of these pumps vary on fluid types. If you are looking for a booster pump in the gas industry, get a gas booster which is similar to a gas compressor. It works on a mechanism that has only a single stage of compression and is also used to increase the pressure of a gas that is already above ambient pressure. You may also find two-stage boosters that can be used for increasing gas pressure, transferring high-pressure gas, charging gas cylinders and scavenging.
Positive Displacement Pumps
These pumps are also known as gear pumps or rotatory pumps. These pumps have the ability to transfer difficult liquids like those containing solids or highly viscous fluids. They work by using rotating parts to push liquid into an enclosed volume. Gear pumps are perfect for thick fluids that are transported at a lower stream rate but higher pressure.
These pumps are also used in the upstream phase of an oil refinery. They are a more compact unit that builds high-pressure ratio making them stand out amongst the most proficient kinds of pumps. These pumps are reasonable and efficient. There are different types of positive displacement pumps that are used in the oil and gas industry:
Screw Pumps – It is a kind of positive displacement pump that use one screw to move fluids or solids. A single screw rotates in a cylindrical cavity, by moving the material along the screw’s spindle. These pumps are used to pump high-pressure viscous fluids.
Multi-plunger Pumps – In this type of positive displacement pump high-pressure is stationary and a smooth cylindrical plunger slides through the seal. These pumps can be used at higher pressure. Multi-plunger pumps have a rigid design, long life, custom designs, and are very easy to maintain.
These are one of the most widely used pumps. These pumps are completely submerged in the fluid to be pumped. These pumps prevent pump cavitation, a problem associated with a high elevation difference between the pump and fluid surface.
These pumps push fluid to the surface as opposed to jet pumps that create a vacuum and rely on atmospheric pressure. Submersible pumps are very efficient.
Either you are looking for pumps used for upstream, midstream, or downstream phase these pumps can be used for every phase. These pumps are the most common pumps used in the oil and gas industry.
