Abstract:

Under the "Clean India Mission", the Ministry of Urban Development (MoUD) of India is investing US$ 9 Billion to clean up 75 largest cities in India. Waste to Energy (WTE) plants will be a key to its implementation. A new state-of-the-art WTE plant in New Delhi is planned for this purpose to set an example for other cities to follow. Delhi generates 8,400 tons per day (TPD) of Municipal Solid Waste (MSW), which is expected to double in the next 15 years. The current capacity of waste processing plants in Delhi is only 8,000 TPD. It is estimated that by the year 2050, Delhi would require 100 km2 of landfill area, which is 7% of the total land area of the capital for waste disposal unless a new WTE plant is commissioned. The existing landfill sites in Delhi have dangerously exceeded their capacity already. WTE projects have been running successfully in many countries but have produced only mixed results in India and have often been plagued with controversies. This is due to various technical, financial, environmental, political and social factors involved. Hallam Energy at Sheffield Hallam University was commissioned by the Government of India, to conduct a detailed independent investigation into the techno-economic feasibility of such a WTE project in Delhi. The goals of this study were (i) to make an informed decision on whether the proposed WTE facility for Delhi will be technically and financially viable, and (ii) to gain a reasonable understanding of the costs and resources involved in this investment. This work looks at the various challenges associated in setting up WTE plants in developing countries and address key findings including: The capacity of the plant; The capital cost; The electrical power output; Land area requirement; Site selection for the plant; The choice of processes and pre-processing of the feed; Feasibility of tri-generation or CHP; Choice of technologies and equipment; Financial models; Emissions of pollutants and the lessons learnt from past WTE projects in India.

Abstract:

Statement of the Problem: Due to the progress of urbanization and complications in management in this regard, as well as the necessity of controlling pollution stemming from waste production, traditional methods no longer answer the management requirements in this field. Therefore, because of the multi-faceted nature of waste management in large cities, on the one hand, and the necessity of management of financial and human resources, on the other, utilizing methods and features associated with smart cities is of high importance.

Methodology & Theoretical Orientation: In this study, by using radio frequency identification (RFID) systems and reading and processing of the data, in addition to reduction of human resources and current costs, the goal was to determine planning details of the city. The other advantages of this method include reduced pollution associated with collection trucks and lower emission of greenhouse gases due to the shorter staying duration of waste in the bins.

Findings: The results indicated that 12.7% of bins existing in the initial data were identified after the implementation of the current method, resulting in savings in the number of bins, optimal navigation of waste collection trucks, and division of collection. By using smart methods, coding the waste bins and installing reader on trucks, in addition to facilitating instantaneous transparency, all the waste collection elements were analyzed in the electronic panel to allow future planning.

Marcel Kai Loewert has completed his Master of Science degree in Bioengineering at the Karlsruhe Institute of Technology in Germany, where he focused on food process engineering and energy process engineering. Since 2015, he has developed knowledge in the field of heterogeneous catalysis in microstructured reactors, especially in decentralized applications for synthesis gas generation, handling and conversion to synthetic fuels. His fields of work focus on product analysis (gas phase, liquid phase, and solid wax phase), commissioning, experimentation planning, process simulation and operando methodology for catalysts.

Abstract:

The Fischer-Tropsch (FT) reaction is usually operated stationary to convert syngas from fossil carbon sources to produce high-grade synthetic fuels. Nowadays, huge efforts are made to close the anthropogenic carbon cycle based on renewable resources. In the context of Power-to-X, an excess of renewable electrical energy could be used to transform water and CO2 into syngas, which is the essential feedstock to the Fischer-Tropsch reaction. The problem of renewable electricity is its decentralized and fluctuating nature which is often misaligned with the actual demand. To avoid large, expensive storage tanks for hydrogen, dynamic operation of the synthesis step is considered for effective storage processes. A large internal surface area strongly improves heat and mass transfer within microstructured reactors developed at IMVT. Due to their compactness compared to industrial reactors, they operate in much smaller applications, while showing a distinctly higher overall process performance. Consequently to the lower holdup, changes in process parameters such gas velocity, concentration or temperature can occur faster. Additionally, innovative evaporation cooling could help change reactor temperatures in shorter time. In this study, highly dynamic changes in temperature and gas composition were applied. The laboratory scale reactor system has the capability to produce up to 7 L of product per day. To determine the limits of this system, periodic changes of different time scales were applied and finally lead to a real-time scenario for highly fluctuating gas concentrations discretized from a solar panel energy output profile to be translated into a simulated, standalone electrolysis unit. Additionally, synchrotron experiments were conducted to analyze the catalyst state during and after drastic parameter changes to measure e.g. the degree of catalyst oxidation during potential deactivation. These experiments were conducted using a special measurement cell compatible with the liquid products that form during reaction and rapid process changes.

Abstract:

 The chief advantage of air solar tower power plants compared to the other concentrating solar power technologies is the ability of achieving temperatures as high as 700°C. This latter depends on the receiver design and the heat transfer fluid used. The heliostat solar field in central receiver systems is considered as the main subsystem due to its high costs (up to 50% regarding the capital expenditure of the total plant). Therefore, the main focus of this study is the design and cost analysis of a heliostat field in an air-based 150 MWe solar tower power plant. Due to its high insolation with annual DNI of 2712 kWh/m², this study was conducted for De Aar region in South Africa. The SF is designed, using SolarPILOT, such that the power delivered meets only the power required by the PB or the TESS at design conditions in order to have an operation strategy that covers peak hour demand with a receiver thermal power of 1210 MWth. In order to demonstrate the high potential of multi-tower configuration in terms of solar energy gained and reduction of investment costs, this configuration was compared to a multi-receiver configuration, where four receivers are mounted on the top of the same tower. Each receiver was designed with a thermal capacity of 302.5 MWth. The results show that, in the first configuration, the annual energy reaching the receiver is about 2296.33 GWh, with a 477 M$ of solar field cost investment, while in the second configuration, the annual energy produced is about 2490 GWh with only 184 M$ of solar field cost investment.It can be concluded that the greatest gain of energy is achieved with multi-tower configuration with a low cost comparing with the first configuration.Future work includes an estimation of the overall techno-economic performance of the plant coupled with thermocline packed bed storage system and steam Rankine cycle.

Abstract:

Treatments of fluoride (F), copper (Cu) and F-Cu from semiconductor-based silicon etching rinse baths by electrocoagulation (EC) using aluminum plate electrodes were investigated in this study. The effects of important process variables such as current intensity, initial pH and initial concentration on the removal efficiencies of F and Cu were evaluated. Removal efficiencies for F and Cu in the single system were found at about 99% at optimum operating conditions.The highest removal efficiencies were achieved at pH 3 for F and between pH 3 and 5 for Cu containing synthetic wastewaters. Experiments were conducted with different F/Cu ratio when Cu concentration was kept constant and F concentration was increased, the highest removal efficiency was observed at lower concentrations. EC study provided high removal efficiencies of F and Cu from semiconductor synthetic wastewater.
