This report presents a cost analysis of Monoethylene Glycol (MEG) production from ethylene This process consists of a two-steps process. First, ethylene is oxidized with oxygen to produce ethylene oxide, which is further hydrolyzed to MEG. Diethylene glycol (DEG) and triethylene glycol (TEG) are also generated as by-products in the process. This report was developed based essentially on the following reference(s): (1) "Ethylene Oxide", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) "Ethylene Glycol", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Ethene, Shell Master, Scientific Design, Oxidation, Dow METEOR
This report presents a cost analysis of Polyethylene Furanoate (PEF) production from monoethylene glycol (MEG) and 2,5-furandicarboxylic acid (FDCA). In this process, FDCA and MEG are polymerized to PEF in two polymerization steps in order to obtain Bottle-Grade PEF: melt-phase polymerization and solid-state polymerization. This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses: * Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up * Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs * Raw materials consumption, products generation and labor requirements * Process block flow diagram and description of industrial site installations (production unit and infrastructure) This report was developed based essentially on the following reference(s): (1) WO Patent 2015137807, issued to Furanix Technologies in 2015; (2) US Patent 6749821 issued to UOP in 2004 Keywords: Polyethylene Furanoate, Polyethylene 2,5-Furandicarboxylate, PEF, Green PEF, FDCA, MEG
This report presents a cost analysis of Polyethylene Terephthalate (PET) production from ethylene glycol and purified terephthalic acid (PTA). The process examined is a typical melt-phase polymerization followed by solid-state polymerization. In this process, initially an oligomer intermediate is produced by the esterification of PTA with ethylene glycol. The oligomer then undergoes a melt-polymerization and a solid-state polymerization, leading to a bottle grade PET.

The reconciliation of economic development, social justice and reduction of greenhouse gas emissions is one of the biggest political challenges of the moment. Strategies for mitigating CO2 emissions on a large scale using sequestration, storage and carbon technologies are priorities on the agendas of research centres and governments. Research on carbon sequestration is the path to solving major sustainability problems of this century a complex issue that requires a scientific approach and multidisciplinary and interdisciplinary technology, plus a collaborative policy among nations. Thus, this challenge makes this book an important source of information for researchers, policymakers and anyone with an inquiring mind on this subject.
This report presents a cost analysis of Monoethylene Glycol (MEG) production from ethylene The process examined is similar to Shell OMEGA process. In this process, ethylene is first oxidized with oxygen to produce ethylene oxide, which is further converted to MEG. This report was developed based essentially on the following reference(s): (1) US Patent 8329959, issued to Shell in 2012 (2) US Patent 8217190, issued to Shell in 2012 Keywords: Ethene, Shell, OMEGA, Only MEG Advantage, Oxidation, Catalytic Process
This book focuses on carbon nanotubes and graphene as representatives of nano-carbon materials, and describes the growth of new technology and applications of new devices. As new devices and as new materials, nano-carbon materials are expected to be world pioneers that could not have been realized with conventional semiconductor materials, and as those that extend the limits of conventional semiconductor performance. This book introduces the latest achievements of nano-carbon devices, processes, and technology growth. It is anticipated that these studies will also be pioneers in the development of future research of nano-carbon devices and materials. This book consists of 18 chapters. Chapters 1 to 8 describe new device applications and new growth methods of graphene, and Chapters 9 to 18, those of carbon nanotubes. It is expected that by increasing the advantages and overcoming the weak points of nanocarbon materials, a new world that cannot be achieved with conventional materials will be greatly expanded. We strongly hope this book contributes to its development.
With an ever-increasing human population, the demand placed upon the agriculture sector to supply more food is one of the greatest challenges for the agrarian community. In order to meet this challenge, environmentally unfriendly agroch- icals have played a key role in the green revolution and are even today commonly recommended to circumvent nutrient de?ciencies of the soils. The use of ag- chemicals is, though, a major factor for improvement of plant production; it causes a profound deteriorating effect on soil health (soil fertility) and in turn negatively affects the productivity and sustainability of crops. Concern over disturbance to the microbial diversity and consequently soil fertility (as these microbes are involved in biogeochemical processes), as well as economic constraints, have prompted fun- mental and applied research to look for new agro-biotechnologies that can ensure competitive yields by providing suf?ciently not only essential nutrients to the plants but also help to protect the health of soils by mitigating the toxic effects of certain pollutants. In this regard, the role of naturally abundant yet functionally fully unexplored microorganisms such as biofertilizers assume a special signi?cance in the context of supplementing plant nutrients, cost and environmental impact under both conventional practices and derelict environments. Therefore, current devel- ments in sustainability involve a rational exploitation of soil microbial communities and the use of inexpensive, though less bio-available, sources of plant nutrients, which may be made available to plants by microbially-mediated processes.
This book offers a comprehensive review on biomass resources, examples of biorefineries and corresponding products. The first part of this book covers topics such as different biorefinery resources from agriculture, wood processing residues and transport logistics of plant biomass. In the second part, expert contributors present biorefinery concepts of different biomass feedstocks, including vegetable-oils, sugarcane, starch, lignocellulose and microalgae. Readers will find here a summary of the syngas utilization and the bio-oil characterization and potential use as an alternative renewable fuel and source for chemical feedstocks. Particular attention is also given to the anaerobic digestion-based and Organosolv biorefineries. The last part of the book examines relevant products and components such as alcohols, hydrocarbons, bioplastics and lignin, and offers a sustainability evaluation of biorefineries.
Natural gas is a vital component of the world's supply of energy and an important source of many bulk chemicals and speciality chemicals. It is one of the cleanest, safest, and most useful of all energy sources, and helps to meet the world's rising demand for cleaner energy into the future. However, exploring, producing and bringing gas to the user or converting gas into desired chemicals is a systematical engineering project, and every step requires thorough understanding of gas and the surrounding environment. Any advances in the process link could make a step change in gas industry. There have been increasing efforts in gas industry in recent years. With state-of-the-art contributions by leading experts in the field, this book addressed the technology advances in natural gas industry.
