Abstract Nanofluids, which are new heat transfer fluids, have shown some unique behaviours in thermal fluid systems. First, their effective thermal conductivity can be much higher than conventional heat transfer fluids. Secondly, magneto-rheological nanofluids (MRNF) can control the viscosity and heat transfer in an appropriate magnetic field. On the negative side and in general, nanofluids have shown more effective viscosity than the base fluids. The idea is to find the optimum way to prepare them and find the optimum range for each nanofluid to provide the maximum heat transfer performance. Consequently, they could significantly reduce the size and materials in heat transfer applications. Therefore, investigations into nanoparticles and nanofluids are important regarding material and energy management as well as environmental issues. This presentation concerns applications, modeling, common mistakes, challenges and opportunities for nanofluids research.

Abstract To fulfill the desire of process engineers and business decision-makers, it is important to operate the process industries optimally to improve the efficiency, improving the energy-saving potential, reducing the plant operating cost as well as environmental pollution ensuring the process safety of the entire plant operation. Due to the involvement of conflicting objectives, i.e., the process criteria, process safety, environmental and profit, chemical processes are perfect contender for multi-objective optimization and analysis. In this talk, two important real world processes, namely Natural Gas Sweetening and Dehydration processes are analyzed using the multi-criteria perspectives. In Oil & Gas industry, gas sweetening process is inevitable when raw natural gas contains acid gases like H2S and CO2. Removal of these acid gases is important from the green future perspective and is essential since their presence poses severe corrosion problem to the downstream process lines and equipment. The %CO2 removal and %H2S removal for process objectives, damage index for process safety, profit before tax, return on investment for economic, global warming potential, acidification potential for environmental objectives are used to analyses multi-criteria optimization scenarios. Energy-saving potential and profitability of the operating plant have also been highlighted under normal and deteriorating feed conditions for the desired sweet gas purity and process safety. Process retrofitting aspects are introduced and the performance of retrofitted based multi-criteria analysis is compared with base case processes. Importance and challenges of complex industrial processes towards conflicting criteria are discussed. Category: Upstream (Gas Processing) Short Biography Ashish M.

Abstract Global warming and air pollution are among the main challenges that threaten human health. The excessive use of fossil fuels for energy and material production in the last two decades is now directly linked to climate change. Therefore, extensive efforts are being directed towards the exploitation of clean power sources. Fuel cells are one of the most promising sources of clean energy considering their lower carbon footprint (depending on the fuel used), low nitrogen and sulfur oxide emissions and their low noise levels. Among the various types of fuel cells, proton exchange membrane (PEM) fuel cells are receiving considerable attention. They operate around 80◦C, and characterized by their all-solid structure, quiet operation and fast start-up. High temperature (~ 200°C) operation is desired in PEM fuel cells for several reasons. It improves the cell tolerance for impurities, thus, allowing the use of fuels other than hydrogen or impure hydrogen. It also enhances reaction kinetics and allows the recovery of useful heat. This talk will address the current status of fuel cells, challenges and room for improvement. Category: Energy Short Biography Dr. Amani Al-Othman joined AUS in 2013.

Abstract Fines migration is a formation damage mechanism which results in permeability reduction and production problems due to the alteration in electrostatic and hydrodynamic forces in porous media. Fine migration is mainly caused by changes in the attractive and repulsive surface forces, which are triggered by mud invasion during drilling activity, the utilization of completion fluid, acidizing treatment, and water injection into the reservoir during secondary and tertiary recovery operations. Hence, estimation of water critical salt concentration and critical injection rate is essential to control and overcome this damage mechanism. In this study a modified model based on DLVO theory is presented to predict the effect of ions present in porous media, injection velocity, and injection strategy on the initiation and extent of fines migration. Different experiments such as coreflooding, Zeta potential measurement, and surface studies were conducted to verify the model and study different approaches such as application of nanofluid injection to control the fines migration. This study showed that the presence of divalent ions significantly affects the electrostatic force, and their presence in the formation water and injection water is beneficial to control fines migration even at low salinity of the injection water. Model and experimental results confirm that the application of nanoparticles increase the attractive force and help to mitigate the fine migration problem.

Abstract Oily wastewater (OW) is detrimental towards the environment and human health. The complex composition of OW need an advanced treatment like membrane technology. Membrane distillation (MD) could give the highest rejection percentage of pollutant in the wastewater as the membrane only allowed the vapor to pass its microporous membrane. However, the commercial membranes in the market are less efficient in treating OW as they are prone to fouling. Thus, the best membrane must be identified to treat OW effectively. This study tested and compared the separation performance of different membranes and comparing between pressure-driven membrane filtration with MD. In this study, several ultrafiltration (UF) and nanofiltration (NF) membranes (NFS, NFX, XT, MT, GC and FILMTEC) were tested for their performance in treating OW (100 ppm). The XT and MT membranes (UF membrane) with contact angles of 70.4±0.2o and 69.6±0.26o respectively showed the best performance with high flux and oil removal rate. The two membranes were then tested for long-term performance for two hours with 5,000 ppm oil concentration using membrane pressure-filtration and MD. XT membrane showed better oil removal percentage of >99%. Despite MD gave a better removal percentage, the flux reduction was high with average flux reduction of 82% compared to the membrane pressure-filtration method which experienced lower flux reduction which is 25%. The hydrophilic MT and XT membranes used were able to avoid fouling well for both methods. However, for the MD method, wetting occurred due to the feed penetrating the membrane pores causing flux reduction. Therefore, it is important to identify the performance and characteristics of the membrane used including the best membrane treatment method.

Abstract Nowadays, polymer-based materials are extensively used for domestic applications because of their ease in economic production and comparable strength. However, most of the polymer materials are non-biodegradable. Hence, conservational environmental policies mandate the replacement or recycling of polymer-based domestic products and components. Besides, discarding flyash in the dumpsites produced from coal-fired thermal power plants aggravates environmental pollution (including groundwater resources). Hence, devising effective waste-management strategies or developing technologies for recycling wastes (polymers and flyash) is the need of the hour. The talk would focus on the need for developing sustainable engineering components through waste management. The science and technology of powder metallurgy processing of waste materials would be elaborated on in detail. Also, case studies on flyash-based ceramic tiles, flyash-polymer composite paver block, flyash-based wind turbine brake pad materials, and hybrid black toner, would be discussed.

Abstract Seismic low-frequency shadow (LFS) is a zone in the seismic data that is characterized by strong anomalously low-frequency energy compared with its surroundings and this has been used as a direct hydrocarbon indicator. It occurs beneath a body that strongly attenuates the energy of the propagating seismic waves. The detection and underlying mechanism of seismic low-frequency shadows (LFSs) have been an issue of debate. Even though the concept of LFS is widely accepted, the method remains limited due to few real field case studies and little understanding of the underlying attenuation mechanism. To understand the attenuation mechanism(s) that is responsible for the occurrence of LFS in fluid-saturated formations, we use the diffusivity and viscosity of the fluid-saturated medium to derive a complex velocity function that characterizes a high-frequency attenuation phenomenon responsible for the occurrence of LFS in a CO2 -saturated formation. We generated synthetic seismic data sets which represent pre- and post-CO2 injection scenarios using 2D diffusive-viscous equations to model the LFS and understand its occurrence mechanism. Furthermore, to demonstrate the applicability of LFS in a real field, a spectral decomposition analysis of time-lapse 3D seismic data of the Utsira Formation, Sleipner Field, North Sea where CO2 is being injected since 1996, is carried out using the continuous wavelet transform and single (common) frequency sections or slices were generated. The LFSs are clearly detected below the reservoir base at frequencies lower than 30 Hz in the post-CO2 injection surveys. The results from the synthetic and real data suggest that the occurrence of LFS in a CO2 -other saturated reservoir is related to the attenuation of high-frequency components and the controlling parameters are diffusivity and viscosity of the saturated fluid. It is shown that the seismic low-frequency shadows are not artifacts but occur due to attenuation of the high-frequency components of the propagating seismic waves in the CO2-saturated Utsira Formation. The LFSs are localized anomalies at the base of the formation; hence, with the present approach, these anomalies cannot be related to the migration of the CO2 plume in the Utsira Formation. The concept of LFS can apply to any formation, which is saturated either with hydrocarbons or CO2; however, the nature and amplitudes of the anomalies might vary. Another interesting aspect of the LFS in time-lapse seismic monitoring could be the mapping of CO2 at the reservoir base, which is not possible through conventional analysis of full-bandwidth data such as amplitude variation with offset, which depends on the top reservoir reflections.

Abstract Traditionally, the development of novel systems and technologies is complemented by testing. Experimental tools for testing and examining the results are expensive and their use is time consuming. In recent years, thanks to the rapid growth in the computational speed, it is seen that the use of computer aided methods in the systems’ design phase contributes greatly to the reduction of the cost and time for the entire technology development process. Experimental methods can improve the computational model by incorporating new data, while computational tools can use this advanced model to analyze structure, properties, and optimization by examining a wide set of possible configurations. Moreover, the simultaneous use of computational and experimental tools allows to tackle problems that cannot be solved using theoretical or experimental methods itself. At this context, overcoming the challenges which hinders commercialization of the technology requires hierarchical theoretical and experimental approaches. Thus, in this session, the focus is the comprehensive understanding and application of Integrated Multiscale Modelling-Simulation (MMS) and Machine Learning (ML) approach which provides new insights for acceleration on the commercialization/utilization for the design and development of novel technologies. The practice of the main concepts is demonstrated through an example of process intensification by reactive-separation systems in power generation process (Integrated Gasification Combined Cycle power plant, intensified by hybrid Membrane Reactor/Adsorptive Reactor system) for simultaneous hydrogen production and CO2 Capture.

Abstract During geometry evolution for dissolution in porous media, the interface surface area of solid and fluid is continuously changed. However, in most studies in the lattice Boltzmann method, the surface area was not calculated. In this research, the effect of not calculating the surface area was investigated. Moreover, applying the non-linear boundary condition was another challenge that was dealt with in this research. In this regard, a general method was presented for applying this type of boundary condition. The proposed method guarantees the locality and orientation independency of the formulations. In another stage of this research, to track the interface of solid fluid during dissolution, the volume of fluid (VOF) method was combined with curved boundary conditions. In most research, for simulating dissolution in the lattice Boltzmann (LB) framework, the volume of pixel (VOP) method mainly was used. In this method, the surface area of the solid-fluid interface was not captured and its value was fixed to one. Therefore, the validity of VOP compared to VOF was evaluated in this research. A comparison of the results showed that VOP calculates the reaction rate by 20-30 % more. Also, the method was applied for dissolution in a single porous medium. Moreover, the effect of dual porosity on the dissolution in porous media was investigated. For this purpose, wormhole and face dissolution patterns in a dual porosity medium were studied. In both patterns, a faster dissolution was observed compared to the single porosity. Since solute can diffuse through grains in the dual porosity medium, thus this facilitates the dissolution. It was also concluded that dual porosity does not influence the face dissolution pattern; however, it affects the wormhole dissolution pattern. Contrary to the medium with single porosity, the constructed wormhole in dual porosity medium was thinner and more elongated so that the solute was exited from the porous medium sooner. In comparison with the single porosity medium, there was less area of the interface in connection with the main path of solute in the dual porosity medium Therefore, the solute in the medium with dual porosity was consumed less and carried on through the wormhole.

Abstract Waste plastics are a problem that blusters the environment so it must be solved. Improved science gives rotary kiln reactor technology by waste plastics gasification process to produce valuable industry synthesis gases mainly carbon monoxide and hydrogen. In this study, concentration was made on avoiding red hot spots RHS that occur in rotary kiln reactor RKR during decomposition of plastic at high temperature to produce synthesis gases (CO, H2). The RKR is a cylindrical vessel inclined slightly to the horizontal, which is rotated slowly about its axis. The main reason is to protect it from damage and prolong its lifetime. Focus is made on the impact of sensitivity analysis variables on process thermodynamics and gas product amount. On the other hand PVC affection on gasification is studied. Different feedstocks are used in this study including PVC, polyethylene, polypropylene, polystyrene, and acrylic. The effect of many parameters is tested including feed moisture, flame temperature, insulation thickness, and the speed of rotation of RKR. • More PVC in the feed leads to fewer synthesis gases conversion in the products as of that more heat is needed so red hot spots will occur and more poison chlorine gas emissions must be processed. • Thickness increasing prevents red hot spots from happening to maintain the rotary kiln reactor from damage and prolongs the lifetime when the outer surface temperature is less than 350 C0 and decreases the heat loss. • Flame temperature must be balanced to give the best conversion and doesn't cause red hot spots as known increasing the flame temperature leads to more waste plastic conversion to synthesis gases on the other hand cause RKR outer surface temperature increasing also radiant heat transfer coefficient increasing that leads to heat loss increasing.
