Lecture Title

Optimal Synthesis and Planning of Sustainable Chemical Processes and Energy Systems

Lecture Abstract

Sustainability has emerged as a key issue in process systems engineering (PSE). Mathematical programming techniques such as mixed-integer programming and global optimization offer a general modeling framework for including environmental concerns in the synthesis and planning of chemical processes and energy systems.

One major critical issue is how to systematize the search for alternatives leading to reductions in environmental impact. Furthermore, aside from anticipating the effect of uncertainties, which are quite pronounced in this area, there is the issue on how to cope with competing economic and environmental objectives. In the area of process synthesis we address the energy and water optimization of biofuel plants.

We present an optimization framework based on superstructure optimization that effectively accounts for energy and water integration, and illustrate its application to the optimization of bioethanol plants. In the area of supply chain optimization we consider first the design of an integrated supply chain for gasoline and ethanol that can deliver a variety of blends.

We also consider the optimal design of centralized and distributed manufacturing facilities for the production of bioethanol. We next address the design of shale gas infrastructures and the associated scheduling of fracturing wells and impaired water management to reduce the consumption of water.

Finally, we consider the environmentally conscious design and planning of hydrogen supply chains for vehicle use using a multiobjective optimization approach coupled with the Eco-indicator 99 to assess the effect on human health.

Incorporating Uncertainties in Pinch Analysis

Lecture Abstract

Pinch Analysis is an important technique to achieve sustainable development through conserving resources in source-sink resource conservation networks.

Diverse applications and methodologies of Pinch Analysis primarily consider only exact and precise parameters. Parametric uncertainties in source-sink networks arise due to changes in operating and environmental conditions, along with the lack of a complete understanding of the processes involved.

This talk reviews recent developments in Pinch Analysis to account for parametric variabilities and uncertainties in resource conservation networks.

Lecture Title

Energy positive wastewater treatment: creating value from an underexploited resource

Lecture Abstract

Typical wastewater treatment processes are large energy consumers. The typical activated sludge process, which is most often implemented for the treatment of municipal and industrial wastewater, has a net energy consumption of about 0.8 kWh per m3 of water treated. For the European Union alone, municipal wastewater treatment is estimated to account for a power consumption of approximately 2,000 MW.

The first step is reducing this vast amount of power usage by enhancing the efficiency of the current treatment processes and the adoption of locally generated renewable energy (e.g., via the use of photovoltaic systems). Whereas this is a prerequisite before further upgrading, the potential is limited.

The real leap forward will come from making use of the chemical energy potential present in wastewater: this is estimated to be as high as 90,000 GWh/y. There are indeed a large variety of chemical compounds present in wastewater which, when applied intelligently, can make a large energy contribution.

For this, innovative methods need to be developed in addition to traditional techniques such as biomethanation. Besides the obvious carbon compounds, other components such as nitrogen compounds will play a major role, leading to innovative types of biofuels.

In this lecture, an evaluation be made of the potential of various approaches to realize this target. Innovative processing schemes will be presented in which existing wastewater plants will be upgraded to net power producers.

The integration of the most promising techniques will be discussed from a technological and sustainability point of view. Finally, the current bottlenecks will be highlighted and the required political and economic incentives to realize this major goal discussed.

"Don’t Waste a Good Crisis?"

Lecture Abstract

The COVID-19 pandemic caught educators, industrialists, governmental leaders and citizens at-large, un-prepared to properly respond to the crises that are happening because of the virus.

As of February, 2021, the Pandemic has caused approximately two million human deaths and hundreds of millions of infected people who are suffering from long-term health effects.

Because many societal institution’s leaders and their members were not prepared for such crises, many socio-economic and ecological crises are being experienced.

The lecturer will focus upon these questions:

  1. What can we learn from previous pandemics and how can those lessons help us to recover from COVID-19?
  2. What can be done to make socio-economic systems that are more flexible and resilient to anticipate and to respond to such crises?
  3. What can be learned to help us make education and training more effective during and after the pandemic?
  4. What can be learned about alternative ways of doing research?
  5. What can we learn that will help us reduce the probability and severity of future pandemics?
  6. What will PRES’21’s participants do when they return home with regard to the foregoing questions?

Lecture Title

Heat transfer optimisation based on a new space thermal resistance network method

Lecture Abstract

Convective thermal resistance along the transverse and streamwise directions may vary significantly in high-temperature fluids and supercritical fluids. However, these variations are usually ignored, and thus the one-dimentional thermal resistance network and uniform heat transfer enhancement elements are used.

In this talk, a new space thermal resistance network is proposed. The variations of convective heat resistance along the transverse and streamwise directions could be considered, and quicker and more accurate prediction for heat transfer in the high-temperature fluids or supercritical fluids can be obtained. A new optimization method based on optimal thermal resistance ratio is then proposed for heat transfer enhancement.

At last, two examples are given to introduce how to use the new optimization method to enhance the heat transfer performance in a double-fluid heat exchanger and a single-fluid heat sink.

The results show that the comprehensive heat transfer performance of the optimized non-uniform heat transfer enhancement elements by using this new optimization method is significantly improved compared with the traditional thermal design method.

Implementing Green Chemistry Principles for Circular Economy Towards Sustainable Development Goals

Lecture Abstract

Green Chemistry is the molecular science of sustainability to design chemical products/processes that reduce the use/generation of hazardous substances, thereby enhancing energy efficiency, building green supply chains, and creating business opportunities.

It is required to establish national governance framework for a new waste management policy including sustainable production and consumption, resource efficiency maximization and environmental impact minimization at every stage of the product and service lifecycle for circular economy.

On the other hand, the chemical industry should promote efforts to manage materials and products on a life-cycle basis and adopt the Extended Producer Responsibility (EPR) policy for multi-scale analysis system in the petrochemical industry and establish interdisciplinary communication platform for policy prospective and implement professionalism integrity teamwork innovation for “Cooperate Culture”.

The academia should build intelligent recycling system based on smart device, IOT, big data and intelligent sanitation system strengthening the energy and resource sustainability. Finally, the chemical industry would promote SDGs by establishing circular economy business model based on RESOLVE (Regenerate, Share, Optimize, Loop, Virtualise, Exchange).

Systems Engineering Makes the Carbon Go Round – From Molecular Design to Net-zero Plastics

Lecture Abstract

Our linear model of producing chemicals and plastics is unsustainable. The chemical industry needs to replace its current fossil basis with renewables. Since deCARBONization is no alternative for chemicals and plastics, renewable carbon sources are required.

The conversion of these renewable carbon sources into chemicals relies on innovation on the molecular scale, but needs to be rapidly upscaled to efficient processes and integrated into the highly integrated supply chains of the chemical industry.

In this presentation, we will present systems engineering approaches to address the transformation towards a circular chemical industry. Circular carbon can come from biomass, CO2, and waste.

Novel chemical transformations of these carbon feedstocks need be rapidly analyzed, optimized and upscaled. For this purpose, we integrate molecular design methods into conceptual process design.

To design towards both economic and environmental objectives already at early stages of development, predictive methods for life-cycle assessment are developed. The resulting optimized conversion processes are then integrated into a bottom-up model of the chemical industry.

Thereby, trade-offs and potential synergies can be resolved between the renewable carbon sources biomass, CO2 and waste recycling. Promising circular pathways are identified leading towards a net-zero chemical industry.

Water - The Global Challenge and Everybody’s Business: Social & Technological Perspective

Lecture Abstract

Thirty three percent of the world population do not have decent toilet and 11% of the world population do not have clean water close to home. Globally, about 2 billion people use a drinking water source contaminated with faeces.

Quality water and quality life go hand in hand. The food we eat, the house we live in, the transports we use and the things we cannot do without in 24/7/365 determine our quality of life and require sustainable and steady water supplies.

Exponential growth in population and improved standards of living require increasing amount of freshwater and are putting serious strain on the quantity of naturally available freshwater around us. The Ancient Mariners' rime: "Water, water everywhere/Not a drop to drink" is in line with 97% of the planet's water being either salty or undrinkable.

By the year 2030, the global needs of water would be 6900 billion m3/day. Currently the demand for freshwater is increasing by 64 billion cubic meters a year while the world’s population is growing by roughly 80 million a year.

At present, more than 20% of the world’s population live in areas of physical scarcity of water. Moreover, around 25% of the world's population face economic water shortage where their countries lack the appropriate infrastructure to take water from the source.

As the world population grows, the heavily industrialised world we live or strive to live continues to generate vast volumes of wastewater plagued with industrial effluents, sewage, and many harmful, some carcinogenic, by-products, which are often simply disposed of in rivers and oceans. Contaminated water transmits diseases such as diarrhoea, cholera, dysentery, typhoid, and polio cause over half a million diarrhoeal death each year.

The yuck factor, the terms such as recycled sewage and toilet-to-tap used by media in characterizing reclaimed water, give significant negative images to augment reclaimed wastewater reuse, especially for drinking and agricultural production purposes. Although farmers of many countries do not perceive any problem with the quality of the yield produced by wastewater, the social acceptability of the use of wastewater for agriculture is poor.

Global thirst will turn million into water refugees. The disputes over water will inevitably become more common, as 220 river basins globally are shared by two or more countries and scarcity of water can lead to riots. Without more effective water management systems, lack of water availability will become a problem threatening national security in many countries.

Water insecurity is not an issue that can be understood from the perspective of one discipline. Water affects everybody. Apart from the technological, scientific and engineering dimensions, there is an essential social dimension to water insecurity.

Although some of the technological problems being faced regarding the water security and water management could easily be resolved in a matter of years, social and political issues regarding water management will take much longer time to resolve.

This talk will highlight some of the social and technical issues around water which is a grand challenge of the world requiring multidisciplinary approach for the solution.
