Opis:: Crude oil and its derivatives migration in porous structure are important aspects of chemical engineering, since they are vital for processes such as oil extraction and soil remediation. Understanding the multiphase flow in porous rocks is necessary for Enhanced Oil Recovery (EOR) and can lead to this process intensification. In methods of oil extraction such as water flooding or polymer flooding liquids are pumped with high pressure to increase the sweeping efficiency of medium. Thus, the knowledge in this field is important for all people engaged in this process. Oil and its derivatives transport in porous structure occurs also during ground leaching techniques used in soil remediation after emergency release of these liquids. Therefore the research in field of transport in porous media are necessary to conduct this process efficiently. The aim of the experiment was to check the sweeping ratio of paraffin from porous structure for different volumetric flow of leaching liquid. We also measured pressure at the inlet to bed, which allowed us to follow the stages during elution process. To analyze concentration in obtained samples we used TurbiscanLab® device.

Opis:: Emulsions are interesting dispersed systems that are necessary for a number of technological processes. Their flow through porous structures have many applications in the field of chemical engineering. Enhanced Oil Recovery (EOR) techniques, soil remediation and various treatment methods of oily wastewater are good examples of emulsion flow in porous structure. The phenomenon of dispersed system flow through porous media is not easy to describe, mainly because of rheological behavior of emulsions and porous structure properties. During two phase flow of oil and water through porous bed it is possible to observe the interception of oil to porous structure, as well as filtration of oil in pores. In this study, we tried to examine the influence of the fraction size as well as migration process history on permeability of porous bed.
