Sustainability Assessment For Energy Systems And Chemical Process Industries, Michael J. Matzen
Sustainability Assessment For Energy Systems And Chemical Process Industries, Michael J. Matzen
Department of Chemical and Biomolecular Engineering: Theses and Student Research
Sustainability has become an important factor in the chemical process and energy industries with a strong drive for process improvements towards more environmentally conscious solutions. However, there are many ways of defining sustainability and even more ways of trying to determine how sustainable a process is. This work looks into applying a conjunction of tools including; process simulation, multi-criteria decision matrices and life-cycle assessment to more quantitatively determine sustainability metrics. We have applied these tools for the production of electricity, methanol and dimethyl ether. A novel method of electricity production, in chemical looping combustion (CLC), was used that inherently involves …
Implementation Of Sustainability Improvements At The Facility Level: Business Motivations And Impact Of P2 Intern Recommendations, Vincent D. Kuppig
Implementation Of Sustainability Improvements At The Facility Level: Business Motivations And Impact Of P2 Intern Recommendations, Vincent D. Kuppig
Department of Environmental Engineering: Theses and Student Research
Many sustainability and pollution prevention (P2) technical assistance programs exist across the Unities States. There is a need to quantify the actual impact using various metrics and, in addition, to identify the driving forces behind a company’s decision-making process. The University of Nebraska-Lincoln Partners in Pollution Prevention and the Kansas State University Pollution Prevention Institute intern programs partnered to complete 30 reassessments in 2014 to obtain specific information related to each P2 recommendation. After being reassessed, the clients were surveyed concerning their motivations for implementing and not implementing each recommendation; 23 clients responded to the survey.
The clients surveyed were …
Sustainability And Economic Analysis Of Propylene Carbonate And Polypropylene Carbonate Production Processes Using Co2 And Propylene Oxide, Yaşar Demirel
Yaşar Demirel Publications
Currently, the industrially important polycarbonates are synthesized from bisphenol A and diphenyl carbonate, which are highly toxic and hence other feasible alternatives are preferable. Following the considerable advances on the catalyst for the synthesis of carbonates from CO2 and propylene oxide (PO), industrial scale processes for the productions of propylene carbonate (PC) and polypropylene carbonate (PPC) have been designed and simulated with sustainability and economic analyses. The CO2 is supplied by a nearby bioethanol plant, while the PO from a petrochemical process. The first part of the study is for the production of 200 million lb/year cyclic PC …
