The principle of drag reducer for crude oil and refined oil
I often receive customer inquiries about crude oil drag reducer products. The drag reducer is non-toxic and has no side effects on oil products. It is used to reduce the flow resistance of oil products in pipelines during turbulent flow. It is widely used in crude oil and refined oil. In the pipeline, at a lower injection concentration, a drag reduction rate of more than 70% can be obtained. So what is the principle of the drag reducer for crude oil and refined oil?
The principle of drag reducer for crude oil and refined oil:
The drag reducer is a kind of viscoelastic polymer. After it is injected into the pipe, the polymer molecules in the drag reducer fully expand and interact with the turbulence of the flowing fluid, absorbing the energy of the thin interlayer of the pipe flow. Thus, the liquid molecules that interfere with the thin interlayer enter the turbulent core from the buffer zone, reduce the degree of turbulence and prevent it from forming turbulence, thereby reducing the flow resistance of oil.
The drag reducer has the advantages of small addition amount, obvious drag reduction effect, good shear resistance, easy to dissolve in pipeline fluid, no adverse effect on oil products and downstream users, convenient injection during use, and non-toxic product itself. After being injected into the pipe, it can be dispersed quickly to avoid entanglement between polymer chains, and the extension of molecular chains is not restricted to achieve drag reduction effect.
The product is a slurry composed of drag reducing polymer, surfactant and dispersion medium. After the product is injected into the pipeline, the polymer will quickly dissolve into the oil (the dissolution time is related to the nature, temperature, and water content of the oil), so that the turbulence of the oil is effectively suppressed during the flow, thereby realizing drag reduction effect.
However, when high molecular polymers are subjected to strong shearing areas such as centrifugal pumps, elbows, valves, and orifice plates, the polymer molecular chains are easily damaged by external forces and the drag reduction effect is significantly reduced. Therefore, the injection system uses gear pumps and columns. The plug-type metering pump performs pressure increase treatment on the drag reducer to reduce the shear damage to the drag reducer.
