Hydrodynamic and kinetic study of an elution of a high viscosity liquid from the sand bed using eluent of low viscosity

摘要

The study was aimed to determine the hydrodynamic of water seepage through a porous bedsaturated with different amounts of high viscosity liquids. An attempt was made to describe theprocess of seepage through beds saturated with oils using the theory of outflow of a liquid from thetank. It was assumed that the discharge coefficient will represent changes of flow resistance duringthe process. It was found that the dependence of this factor on time is linear. In the second part ofthis work kinetics of the seepage process was investigated. Dependence of oil concentrations, elutedfrom the deposit with the flowing water, on time has been evaluated. Thanks to these studies it waspossible to determine the effectiveness of an elution of high viscosity liquids from porous bedsusing water as the washing out liquid.
