The purpose of this project is to consider and evaluate the economic attractiveness of a process producing 250,000 lb/h of acetic acid by the selective carbonylation of methanol via carbon monoxide with the use of an iridium tri-iodide catalyst. Initial cost estimates of this process will be completed prior to the completed rigorous design to ensure the process is economically viable and meets product specifications. A full cost analysis will then be made on the initial design to further verify the process will meet product specifications and is economically attractive to the business. A recommendation to continue investigating will be made based on the analysis of the investment cost and annual operating costs of this reaction/separation system.
An economic analysis was performed on the selected design. The total capital cost for this project is $145 million, with a yearly utility and incremental cost of $62 million and $90 million, respectively. The required ten-year return on investment was found to be 15%, when the Acetic Acid is sold at a price of $437 /ton. When the Acetic Acid is sold at $745/ton (achieves 15% 1-year ROI), an ROI of 547% is achieved for a 10-year period. In order to achieve a five-year ROI of 15%, the selling price of Acetic Acid is only increased to roughly $455/ton.
Poster submitted to 2014 Dublin Core Metadata Initiative International Conference. Stemming from a project to convert metadata from Dublin Core to VRA, the University of Cincinnati Libraries outlines a successful workflow to improve vendor-generated metadata for a large digital collection of archival materials.
Scholar@UC - scholar.uc.edu - is the faculty self-submission repository currently in development at the University of Cincinnati (UC). Using the Hydra framework, this system comes in an environment of dramatic change: new partnerships across campus and with other entities, new engagement with faculty and stakeholders, growing needs for internal staff job development, and development of new researcher services. The UC Libraries is lean on staffing in comparison with its peers, so we face unique challenges that require flexibility and creativity. We embrace both nimble processes and a strong sense of risk-taking, to ensure that Scholar@UC becomes a critical enterprise system. This panel reflects on three aspects of our engagement and development efforts. First, we will discuss outreach efforts to bring together a small set of “early adopter” faculty, and the process of assembling feedback in a personalized, interview-based setting. Then, we will discuss the process to transform this feedback into functional use cases that prioritize needs and desires. Finally, we will discuss building a small and high-functioning software development team, and collaboration with UC’s central IT department and other local/national development efforts. We think this presentation will offer insight for other institutions with ambitious agendas and limited means.
