Life-Cycle Analysis Of A Cement Manufacturing Plant Co-Firing Hazardous Waste In The Usa, Stephen P. Holt
Life-Cycle Analysis Of A Cement Manufacturing Plant Co-Firing Hazardous Waste In The Usa, Stephen P. Holt
Theses and Dissertations
The purpose of this work was to determine the overall environmental impacts associated with the co-firing hazardous waste by burning in a cement kiln to replace the use of coal in the cement manufacturing process. This environmental assessment was conducted using LCA methodology. Understanding the environmental impacts associated with burning hazardous waste in a cement factory could help shape national environmental policy, regulations and the need for site specific human health risk assessments in the environmental regulatory permitting processes. Accordingly, the primary objective of this study was to evaluate the environmental impacts from the hazardous waste burning for energy recovery …
Improving Cooling Tower Chemistry Control And Cost Savings Through Automation, Ryan Matthew Maxwell
Improving Cooling Tower Chemistry Control And Cost Savings Through Automation, Ryan Matthew Maxwell
Theses and Dissertations
Proper chemistry control of cooling towers reduces corrosion, biological growth, and precipitation of solids. Therefore, improving control can lead to increased equipment life, operating efficiency, and safety. Chemistry of cooling towers is highly dependent on loading, weather, and time. As such, cooling tower chemistry varies day to day and even hour to hour, requiring either continuous controls or large operating bands. Through automation, 24/7 monitoring and control can be achieved, allowing for deliberate operation within tight operating bands. As a direct result of automation water consumption has been reduced by 9.1 million gallons per year, CL-49 use has been reduced …
The Application Of Lean Six Sigma To Improve A Business Process: A Study Of The Order Processing Process At An Automobile Manufacturing Facility, Sherrian Francina Ellis
The Application Of Lean Six Sigma To Improve A Business Process: A Study Of The Order Processing Process At An Automobile Manufacturing Facility, Sherrian Francina Ellis
Theses and Dissertations
The objective of this study is to explore the application of Lean Six Sigma to determine root causes of process inefficiency and make recommendations for improving the order processing process at an automobile manufacturing facility. State of the art process quality improvement initiatives Lean, Six Sigma, and Lean Six Sigma are used to explore literature and provide a strong theoretical background for this study. Since the study utilizes both quantitative and qualitative data, the study’s methodological approach is classified as mixed methodology. The study is empirical in nature, and single case study is strategy chosen to complete the study. The …
