Investigating the Effectiveness of Recycled Agricultural and Cement Manufacturing Waste Materials Used in Oil Sorption

Abstract

This research investigates how sorbents made from recycled waste materials affect the properties of water used to remove residues flushed from oil tanks transported by rail. The mineral sorbent was added to water following the flushing process. Water temperatures were maintained at 21 °C and 70 °C for a contact period of 30 min. The experiments demonstrated that: when the sorbent is active, turbidity removal efficiency was about 64%; color removal efficiency of 56% was obtained; and total iron concentration removal was approximately 68%. The effect of the characteristics of the materials on the adsorption capacity was evaluated using the removed amount of oil per one gram of every sorbent. It was found that straw sorbent oil adsorption capacity was up to 33 mg/g, peat sorbent 37 mg/g, and mineral sorbent 1.83 mg/g. The following were also measured during the experiment: temperature, pH, chemical oxygen usage, total iron concentrations, suspended matter, and oil concentrations. The findings show that recycled sorbents obtained from waste materials are environmentally sustainable and can be reused to treat water that has been used to flush oil transported in rail tanks.

Reducing the negative impact of accidents associated with the release of dangerous substances to environment

“…As a follow-up to the reaction, it is necessary to test various products and to compare real findings with technical sheets and norms. The problematic of appropriate sorbent implementation is a part of many investigations, which aim to determine the right sorbents or substances for the elimination of the negative impact of escaping substances on the environment (64)(65)(66). The results and comparison of testing will allow companies to choose a sorbent and to also continue with the reaction after the sorbent can no longer absorb the substances.…”

Recycled Materials in Civil and Environmental Engineering

“…In the paper by Valentukeviciene and coworker [ 21 ], sorbents from agricultural and cement manufacturing waste were used to remove oil residues in wastewater with a turbidity removal efficiency of 64%, and color removal efficiency of 56%, and total iron concentration removal ~68%. Moreover, straw sorbent oil adsorption capacity was up to 33 mg/g, peat sorbent 37 mg/g, and mineral sorbent 1.83 mg/g, demonstrating the effectiveness of these recycled sorbents as environmentally sustainable materials for wastewater treatments.…”

Usage of sorbents for diminishing the negative impact of substances leaking into the environment in car accidents

“…In the event of a car accident connected with a leakage of certain dangerous substances into the environment it is possible to consider a proper usage of sorbents to capture the substances an effective reaction. The problematic of implementing sorbents is a part of many experiments, which aim to determine the correct sorbents or other substances to eliminate the negative impact of escaped substances on the environment (87)(88)(89)(90). The data that we observed are beneficial in practice for emergency units, but also for crisis management or enterprises.…”
