|Title:||Development Of Intensified Hybrid Equipment: Reactive Molecular Distiller|
Wolf Maciel M.R.
Maciel Filho R.
|Abstract:||Studies indicate the existence of fields with so heavy oils that the simple rise and drainage from the base of the oil well to the surface seems to be impracticable in a first analysis, mainly in oil fields Off-Shore. New alternatives, with the objective of reducing the API degree and the viscosity of these oils, are being developed to enable upgrading of the extra-heavy oil. Processes to transform the oil involve thermal or catalytic cracking which imply in transforming large molecules into smaller ones; or simply physical treatments, as extraction of the heavy fractions of petroleum with supercritical fluid or dilution of the oil with fractions of the proper oil, generating the synthetic oil. In this work, a new equipment was developed: the reactive molecular distiller, in which happens simultaneously the coupling of the molecular distillation (high vacuum) and reactive conversion. It is very robust and can be characterized as a hybrid process and also as an intensified process. This equipment will promote the cracking and the conversion of the heavy fractions in lighter ones, which will be injected in the oil well making possible the withdrawal of the heavy oil from the well. Its most important characteristic is the immediate removal of the reaction products, dislocating the equilibrium in the direction of the desired products. The design, construction and studies of Reactive Molecular Distiller will be detailed in this work, which made possible the idealization of this intensified hybrid equipment.
