Performance Improvement And The Quality Control Of New Oil Drag Reduction

Oil-soluble as a drag reduction of crude oil and refined products pipeline transportation additives, in high turbulence when added to the pipeline wPPm drag reduction of the level, you can reduce a pipe mill increase traffic impacted the role. Drag reduction of the use of a pipeline to a large extent increase the transport capacity and reduce transport costs, making it possible to transport oil flexibility, reduce the constant flow of the pressure on the aging pipeline.At present the industrial application of the main drag reduction for the mixed-α-olefin polymer. Polymer drag reduction in the rate of testing found that the viscosity of different polymer solution, the drag reduction rate is a corresponding different.A-olefins-drag reduction of the application process, there is a lot of shortcomings, the drag reduction through the channels of high-turbulent region, its polymer covalent bond will be cut off into a drag-reducing effects or no bad effects of the DRA Low-molecular-weight polymers, leading to drag reduction rate dropped significantly. In order to maintain the pipeline in the whole of the high-drag reduction rate, must be adopted in each region after the injection of high shear and drag reduction agent.This paper first verify the mixedα-olefin polymer solution and the viscosity of the polymer drag reduction rate of relations. Wu Shi used to measure the viscosity of the polymer solution viscosity, that the greater the viscosity of polymer solution, molecular weight is, the higher the rate of the conclusions of drag reduction.The association of oil drag reduction agent on the basis of preliminary studies to further validate the association hydrogen bonds used to raise the oil drag reduction of shear of the feasibility of that drag reduction of the pump high gear after the turbulent region Can display a certain shear performance. According to the basic theory of polymerization, in-depth discussion of the process of impact copolymer monomer the main factors, through experiments conducted by decomposition of verification, final monomer feeding, the type of emulsifier, the initiator of the types and stages of the emulsion polymerization and Mixing speeds of four main factors.
