“…The cost for a single UAOD unit was measured as $0.70/gal with a sulfur removal of 68%, whereas the cost and removal percentage were $1.39/gal and 90.91%, respectively, for two UAOD units connected in a series. These results indicated that the continuous-flow UAOD process provides excellent economic benefits via the recycling of waste tires, along with elimination of environmental pollution, such as high SO 2 and sulfate PM emission [53].…”

The increasing global population and the rapid industrial development associated therewith have increased the demand for fossil-derived fuel oils. The sources of fossil fuels are limited, and many studies have been being conducted to find alternative fuel sources. Waste tire pyrolysis oil (WTPO) attracts considerable attention as an alternative fuel because its properties are similar to those of diesel oil. However, WTPO has a high sulfur content of >1.0 wt%, which is above the environmental standard limit of 0.1 wt%; therefore, it cannot be used in engines directly. It is thus highly necessary to remove sulfur compounds from tire-derived oils. However, finding an appropriate and environmentally friendly process is proving difficult. This review article presents the various desulfurization methods used to removal sulfur from WTPO, such as hydrodesulfurization (HDS), oxidative desulfurization (ODS), ultrasound-assisted oxidative desulfurization (UAOD), and acid treatment. Of these, HDS is the most expensive as it involves high consumption of hydrogen, high temperature (~450 °C), and high pressure (~200 bar), whereas UAOD is an efficient and economic method of reducing the sulfur content of WTPO.

“…The high energy value and sulphur content implies that desulphurisation of the pyrolytic oil is necessary before it can be used as fuel. The desulphurisation cost for a single ultrasound-assisted oxidative desulphurisation unit was estimated at $0.70/gal with sulphur removal of 68%, whereas the cost and removal percentage were $1.39/gal and 90.91%, respectively, for two ultrasound-assisted oxidative desulphurisation units connected in a series (Chen et al, 2013). The compositions of the oils also varied, containing long and short chains and ringed-structure hydrocarbons.…”

Abstract:This study aims to describe the current problems of the end-of-life tyre system, and propose possible end-of-life tyre management program for Thailand based on cost and environmental perspectives. This study can showcase the process for countries where end-of-life tyre management has not yet been implemented or countries that are facing problems with their end-oflife tyre management systems. Research findings indicate that, without an endof-life tyre program through which customers would be charged a treatment fee, it is not feasible for tyre collectors to collect the used tyres that are discarded more than 150 km from a recycling plant. To increase the end-of-life tyre treatment percentage, a treatment fee must be collected, and the free market system should be used. Subsidy settings, estimated at approximately 20 baht/new tyre or $0.6/new tyre for the collection, processing and use of scrap tyres, should be configured to ameliorate the overall process.Keywords: end-of-life tyre management; life-cycle costs of end-of-life tyre; used tyre management policy; used tyre recycling.Reference to this paper should be made as follows: Mangmeechai, A.

The process performance of the two conditions was compared. The effects of three independent variables, including HRT (6, 12, 18 h), aeration time ratio (1, 1.5, 2) and MLSS content (4000, 7000, 10000 mg/l) were investigated. The central composite design (CCD) and response surface methodology (RSM) were applied to design the experiments, model and optimize the process. In order to evaluate the performance of both systems, ten responses were monitored. The process showed similar performance in terms of sCOD removal in both systems. 83.76% and 70.11%, respectively, were achieved as TN and TP removal efficiencies in the UAAASB mixed by the ultrasonic irradiation. While in the system with mechanical mixing, the maximum TN and TP removal were obtained 57.87% and 57.47%, respectively. The results proved that the high-frequency ultrasonic irradiation (1.7 MHz) had a positive effect on removing TN and TP, sludge settling velocity and effluent turbidity.
