STAND FOR RESEARCH OF TRANSPORTATION PROCESSES OF BLACK AND BITUMINOUS OIL

摘要

FIELD: test equipment.;SUBSTANCE: invention relates to field of flow dynamics, namely, to devices (stands) for studying processes of pumping oil composites, paraffins, cooling down of pipeline during transportation of black and bituminous oil. Stand is designed to find ways to increase efficiency of transportation of rheologically complex oils by research of perspective methods of influence on oil, in particular depressor additives and paraffin inhibitors. Stand contains preparation unit, test unit and information processing unit, wherein the preparation unit consisting of model liquid preparation tank, the first gear-type pump, transport and discharge tanks, test unit consists of piping, the second and the third gear-type pumps, the first and the second centrifugal type pump, drainage tank, at the same time, test unit is made with the possibility of forming closed path of model liquid circulation with the help of section isolation valves.;EFFECT: expansion of functional capabilities of the stand, namely study of dynamics of mixing of black and bituminous oil when pumping one type of oil to another with determination of the velocity profile along mixing path; increase the accuracy of determining thickness of deposits of paraffin and resin on wall of pipeline, including shutdown of the pipeline; the possibility of studying influence of physical fields on hydrodynamics of black and bituminous oil.;16 cl, 1 dwg
