Process of heavy deasphalted Oil with High Content of asphaltenes to conditions of low temperature and pressure

摘要

A continuous process, Low Temperature, low pressure of a single stage, High Performance and low maintenance, desasfaltar,Demetalizar and partially asfaltu00e9nicos desulfurizing Hydrocarbon mixtures such as heavy crude Oils and Heavy asfaltu00e9nicos Waste from the primary distillation or vacuumEither in an original State or in the form of inverse emulsion, oil in water with high contents of cause. The process comprises the following steps: 1.Head - a stage where heavier fractions are separated from those of asphaltic Hydrocarbon Boiling Point fractions with equal or lower than the Solvent used in the prEsente Invention. 2.- a mixed phase of Hydrocarbon or its inverse Emulsion (Oil in water)With a liquid solvent or mixture of Solvents of low molecular weight Liquid aliphatic Chain between C5 and C7, using Static Mixers, Special Design,And a Hydrocarbon Solvent in range of 1 / 3 to 1 / 8. 3.- a stage of Phase Separation, which uses a horizontal or vertical sedimentation where is obtained; a phase rich in light deasphalted Oil (DAO) and solvent phase and another Heavy Asphalt PIf the load can be aqueous emulsion has been introduced as the inverse process. At this stage you can use Accelerators sedimentation such as pulverized Coal or polyelectrolytes. 4.- a stage of Solvent Recovery from the desastaltado Phase rich in crude oil by distillationObtaining the improved Oil and solvent, which is returned to the first stage of the process. 5.- A Phase separation of the Solvent from the heavy phase of Asphalt which obtains asphaltenes and Solvents is recycled to the first phase of the process.If the load is Introduced as the inverse emulsion process, it also requires a phase separation of the water from dehydration.
