Dimethyl Carbonate Production from Ethylene Carbonate - Cost Analysis - DMC E21A


Book Description

This report presents a cost analysis of Dimethyl Carbonate (DMC) production from ethylene carbonate and methanol. The process examined is a typical transesterification process. In this process, ethylene carbonate and methanol are converted into dimethyl carbonate (DMC) and ethylene glycol in a reactive distillation column and purified DMC is obtained through an extractive distillation. Monoethylene glycol is generated as by-product. This report was developed based essentially on the following reference(s): Keywords: Transesteification, ethylene arbonate, DMC, methanol, MEG




Diphenyl Carbonate from Ethylene Oxide and Phenol - Cost Analysis - DPC E21A


Book Description

This report presents a cost analysis of Diphenyl Carbonate (DPC) production from ethylene oxide and phenol. The process examined is similar to Asahi Kasei process. In this process, dimethyl carbonate (DMC) intermediate is initially produced from ethylene oxide and methanol. Then, DMC and phenol react to produce DPC. Ethylene glycol is generated as by-product in the process. This report was developed based essentially on the following reference(s): US Patent 20090163734, issued to Asahi Kasei in 2009 Keywords: Phenyl Carbonate, EO, Carbonation, Transesterification, Reactive Distillation




CO2 Sequestration and Valorization


Book Description

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.

Dimethyl Carbonate Production Process - Cost Analysis - DMC E11A


Book Description

This report presents a cost analysis of Dimethyl Carbonate (DMC) production from methanol The process examined is a typical oxidative carbonylation process. This process is a non-phosgene alternative for DMC production, in which CO, O2 and methanol react in the presence of copper chloride (CuCI) catalyst. Although reaction occurs in the liquid phase, a heterogeneous-phase mixture forms and the product stream is withdrawn from the reactor in vapor phase. The vapor is partially condensed, treated for recovery of catalyst and then subjected to distillation operations. Unreacted methanol is recovered and recycled to the reactor. Purified Dimethyl Carbonate is obtained after separation of side-product water. This report was developed based essentially on the following reference(s): (1) US Patent 20030236428, issued to General Electric Company (2) US Patent 5685957, issued to Enichem Synthesis in 1997 Keywords: Non-Phosgene Process, Phosgene-Free, Oxidative Carbonylation, Enichem, Eni

Reactive Distillation Design and Control


Book Description

After an overview of the fundamentals, limitations, and scope of reactive distillation, this book uses rigorous models for steady-state design and dynamic analysis of different types of reactive distillation columns and quantitatively compares the economics of reactive distillation columns with conventional multi-unit processes. It goes beyond traditional steady-state design that primarily considers the capital investment and energy costs when analyzing the control structure and the dynamic robustness of disturbances, and discusses how to maximize the economic and environmental benefits of reactive distillation technology.




Biodiesel Science and Technology


Book Description

Biodiesel production is a rapidly advancing field worldwide, with biodiesel fuel increasingly being used in compression ignition (diesel) engines. Biodiesel has been extensively studied and utilised in developed countries, and it is increasingly being introduced in developing countries, especially in regions with high potential for sustainable biodiesel production.Initial sections systematically review feedstock resources and vegetable oil formulations, including the economics of vegetable oil conversion to diesel fuel, with additional coverage of emerging energy crops for biodiesel production. Further sections review the transesterification process, including chemical (catalysis) and biochemical (biocatalysis) processes, with extended coverage of industrial process technology and control methods, and standards for biodiesel fuel quality assurance. Final chapters cover the sustainability, performance and environmental issues of biodiesel production, as well as routes to improve glycerol by-product usage and the development of next-generation products.Biodiesel science and technology: From soil to oil provides a comprehensive reference to fuel engineers, researchers and academics on the technological developments involved in improving biodiesel quality and production capacity that are crucial to the future of the industry. - Evaluates biodiesel as a renewable energy source and documents global biodiesel development - The outlook for biodiesel science and technology is presented exploring the challenges faced by the global diesel industry - Reviews feedstock resources and vegetable oil formation including emerging crops and the agronomic potential of underexploited oil crops
