“…The findings showed that the use of various percentages of AS lead to the increase of the resin and asphaltene concentrations, ductility, mechanical properties, elastic modulus, thermal stability, durability properties, and decrease of the aging characteristic of bitumen. So, this research proved the important role of AS as an additive in improving bitumen properties in parallel with author's studies (6). Pyrolysis and simple methods of combustion and gasification are not very cost-effective method and they demand a relatively high budget for the AS removal processes as well as wasting a valuable resource and secondary pollutants dissipation challenges.…”

Background: Plasmatron is a hydrocarbon reformer of fuels and heavy oil sludge with high efficiency in gasification operation. The gasification of acidic sludge (AS) was investigated to assess the technical and financial demands in a model. AS is a by-product of used motor oil (UMO) recycling industries with a large quantity that its reprocessing, refining, and re-refining operations are not performed in Iran. Methods: In this empirical study, the inventory of requirements for generating value-added gaseous products was tabulated based on the recent studies. To develop a techno-economic model, the costs of reactor configuration, equipment, and installation outlay, materials and product costs, facilities, staff salary, land and landscaping budget, and energy demand expenses were taken into consideration. Results: The initial requirements of the project in the screening step were identified and a framework of the economic model was provided to develop and identify the technical dimension of the chemical vapor deposition (CVD) reactor. Conclusion: The findings expanded the technology and its technical demands for identification of screening step of project prior to competing for development and establishment.

Background & Aims of the Study: Given that modern society is a rapidly moving civilization, the production of automobiles resulted in a massive quantity of Used Automotive Oil Filters (UAOFs). So handling the waste stream secures value-added to the national assets and underpins the demands in other sectors. The steel request is highly rising with the population growth, and dismantling and recycling UAOFs produces enough scrap steel to be retrieved in similar applications. Experts of this sector have forgotten this resource. The present review sought the UAOF recycling technologies from the initial step of the project to the recent developments in this area. Also, plasma technology application was addressed as the new technology posed and noticed its modern procedure in the UAOF recycling operation based on the existing technologies. Materials and Methods:In this review, the related articles were searched and studied using key relevant words. Also, we used valuable existing references in this regard. The industrial data employed in the present review refers to the project identification steps expressed and investigated by evaluator teams in the Environmental Impact Assessment (EIA) plan. Results:The collected results and concepts emphasized the redesign and reproduction of UAOF and employing frequently recycled scrap parts in the steel manufacturing operation. Conclusion:The plasma technology enhances the adhesion, wettability, electro-conductivity, and many other characteristics of adsorbents within AOF and generates value-added products and nano-metal oxides from scrap metals of UAOF.

“…Purification was performed to remove unsaturated hydrocarbons, sulfur-and nitrogen-containing compounds, and resinous compounds from oil fractions, the presence of which degrades the performance of petroleum products. As a result of this purification, sufficient amounts of AT were formed, which were not utilized but merged into the pits that are still used nowadays [29][30][31][32][33].…”

Wastepaper Sludge Ash and Acid Tar as Activated Filler Aggregates for Stone Mastic Asphalt

et al. 2023

View full text Add to dashboard Cite

Nowadays, the most common ways to dispose of acid tars and paper production waste are burial or incineration, but it is ecologically and economically expedient to use such waste in building materials. A new variant of filler aggregate—wastepaper sludge ash (paper production waste) and a chemical activator for filler aggregates—acid tar (oil-refining industry waste) is proposed. Elemental and mineralogical compositions of wastepaper sludge ash for comparison with commodity limestone mineral powder are established. Chemical activation of wastepaper sludge ash and limestone mineral powder was carried out and the wetting properties of the obtained materials were investigated by means of primary and neutralized acid tar. The physical and mechanical properties of stone mastic asphalt samples with different filler aggregate variants were studied. The possible chemical transformations in stone mastic asphalt using limestone mineral powder and wastepaper sludge ash activated by acid tar are shown. The possibility of replacing traditional limestone mineral powder with industrial wastepaper sludge ash has been proven, and the effectiveness of activating filler aggregates by acid tar has been confirmed. It was established that acid tar as an activator for filler aggregates does not require neutralization because stone mastic asphalt, in this case, demonstrates better properties compared to acid tar neutralization. As a result of our research, the application of wastepaper sludge ash is possible as a filler aggregate for stone mastic asphalt. And to obtain improved stone mastic asphalt characteristics, wastepaper sludge ash is required to activate 5 wt.% acid tar.
