Abstract:

For safe transportation of crude oil it needs to meet the conditions and quality pumpability. In Romania are extracted over 100 types of crude oils and their transport requiring special conditions of transport (is necesary to protect oil pipe against to frozen ??? congelating and asphalt oil crude). In practice these crude oils are transported and mixed without ensuring final product quality, much needed refineries (especially obtain final products) . Therefore this material present new technologies of blend of crude oils ( such crude oil blending aim being to achieve final products with high processability ) A method of improving the pumpability is one in which various additives are used (to lower the freezing point and / or viscosity). These additives may be polymers or other chemical agents, which modify the wax crystals precipitate from the solution, by one of the following mechanisms [1]: modifier comes out of solution at a temperature slightly higher than the temperature of equilibrium of the solution paraffin; the modifier out of the solution at equilibrium of the solution to co-crystallize with paraffin and paraffin; modifier comes out of solution at a temperature slightly lower than the temperature of equilibrium of the solution is absorbed in paraffin and the paraffin crystals. The modifier present in the solution, acting through one of the mechanisms above, the wax molecules tend to remain as separate entities, by reducing the cohesive forces between the crystals and the forces of adhesion of the wax crystals and other surfaces.
