Regeneration of a fibrous sorbent based on a centrifugal process for environmental geology of oil and groundwater degradation

Abstract

Data were obtained in the experimental study of the process of regeneration of the fibrous sorbent centrifugally. This data characterised the dependence of the sorption rate of fibre loss in the regeneration of fibrous sorbent quality. We found that the increase of sorbent samples regeneration cycles based on polyethyleneterephthalate (PET) fibre of 1 to 50 leads to sorption reduction ratio of 20… 60 % and a weight loss of sorbent is 25-47 %. If the shelf life is increased up to three years, the sorbent does not reduce the rate of sorption and leads to increased sorbent losses due to its mechanical destruction during regeneration in a custom installation centrifugal experimental stand. It was established experimentally that the rate of oil sorption and oil, defined as the ratio of the mass of oil sorbed to the weight of the sorbent used, depends on the mean diameter of the fibres, the sorbent structure and viscosity petroleum products and varies between 5-20. It is also believed that all of the capillaries are filled uniformly and completely with a liquid. Another result of this research is the increase in the process productivity by increasing the average diameter of fibres, reducing the transverse dimension of the fibrous sorbent and increasing the radius and angular speed of the centrifuge perforated drum. A new experimental stand for centrifugal plant separating oil products from fibrous sorbent material has been proposed, which could be used to fight the oil pollution. This is the method used in environmental geology in the degradation of oil. Such a method can be extended to lower the groundwater or geological drilling. © 2016, Technical University of Kosice.
