The Giving Trees: The (Un)Sustainability Of Palm Oil In Indonesia, Amber Rosche 2017 Pepperdine University

The Giving Trees: The (Un)Sustainability Of Palm Oil In Indonesia, Amber Rosche

Seaver College Research And Scholarly Achievement Symposium

Palm oil is the main source of cooking oil for much of Africa, Asia and Brazil. Due to the increasingly high demand for palm oil, countries such as Indonesia and Malaysia have cleared millions of acres of tropical rainforests to create space for oil palm plantations. This deforestation has led to extreme environmental and social concerns such as the burning of peatlands, the endangerment of a number of species, including the Sumatran Tiger, rhinos and orangutans, and the displacement of native populations. Indonesia is the world’s largest consumer and producer of palm oil, producing almost half of the world ...

On October 12–13, a workshop funded by the National Science Foundation was held at Iowa State University in Ames, Iowa with a goal of identifying research needs related to coupled economic and biophysical models within the FEW system. Approximately 80 people attended the workshop with about half representing the social sciences (primarily economics) and the rest from the physical and natural sciences. The focus and attendees were chosen so that findings would be particularly relevant to SBE research needs while taking into account the critical connectivity needed between social sciences and other disciplines. We have identified several major gaps ...


Optimizing Compressed Air Storage For Energy Efficiency, Brian Abels, J. Kelly Kissock 2017 University of Dayton

Optimizing Compressed Air Storage For Energy Efficiency, Brian Abels, J. Kelly Kissock

J. Kelly Kissock

Compressed air storage is an important, but often misunderstood, component of compressed air systems. This paper discusses methods to properly size compressed air storage in load-unload systems to avoid short cycling and reduce system energy use. First, key equations relating storage, pressure, and compressed air flow are derived using fundamental thermodynamic relations. Next, these relations are used to calculate the relation between volume of storage and cycle time in load-unload compressors. It is shown that cycle time is minimized when compressed air demand is 50% of compressor capacity. The effect of pressure drop between compressor system and storage on cycle ...


Lean Energy Analysis: Identifying, Discovering And Tracking Energy Savings Potential, J. Kelly Kissock, John Seryak 2017 University of Dayton

Lean Energy Analysis: Identifying, Discovering And Tracking Energy Savings Potential, J. Kelly Kissock, John Seryak

J. Kelly Kissock

Energy in manufacturing facilities is used for direct production of goods, space conditioning, and general facility support such as lighting. This paper presents a methodology, called lean energy analysis, LEA, for graphically and statistically analyzing plant energy use in terms of these major end uses.

The LEA methodology uses as few as 60 easily obtainable data points. Multivariable change-point models of electricity and natural gas use as functions of outdoor air temperature and production data are developed. The statistical models are used to subdivide plant energy use into facility, space-conditioning and production-related components.

These breakdowns suggest the savings potential from ...

Improving Compressed Air Energy Efficiency In Automotive Plants: Practical Examples And Implementation, Nasr Alkadi, J. Kelly Kissock

J. Kelly Kissock

The automotive industry is the largest industry in the United States in terms of the dollar value of production [1]. U.S. automakers face tremendous pressure from foreign competitors, which have an increasing manufacturing presence in this country. The Big Three North American Original Equipment Manufacturers (OEMs)-General Motors, Ford, and Chrysler-are reacting to declining sales figures and economic strain by working more efficiently and seeking out opportunities to reduce production costs without negatively affecting the production volume or the quality of the product. Successful, cost-effective investment and implementation of the energy efficiency technologies and practices meet the challenge of ...


Energy Efficient Process Heating: Managing Air Flow, Kevin Carpenter, J. Kelly Kissock 2017 Energy & Resource Solutions

Energy Efficient Process Heating: Managing Air Flow, Kevin Carpenter, J. Kelly Kissock

J. Kelly Kissock

Much energy is lost through excess air flow in and out of process heating equipment. Energy saving opportunities from managing air flow include minimizing combustion air, preheating combustion air, minimizing ventilation air, and reconfiguring openings to reduce leakage.

This paper identifies these opportunities and presents methods to quantify potential energy savings from implementing these energy-savings measures. Case study examples are used to demonstrate the methods and the potential energy savings.The method for calculating savings from minimizing combustion air accounts for improvement in efficiency from increased combustion temperature and decreased combustion gas mass flow rate.

The method for calculating savings ...


Measuring Plant-Wide Energy Savings, J. Kelly Kissock, Carl Eger 2017 University of Dayton

Measuring Plant-Wide Energy Savings, J. Kelly Kissock, Carl Eger

J. Kelly Kissock

This paper presents a general method for measuring plant-wide industrial energy savings and demonstrates the method using a case study from an actual industrial energy assessment. The method uses regression models to characterize baseline energy use. It takes into account changes in weather and production, and can use sub-metered data or whole plant utility billing data. In addition to calculating overall savings, the method is also able to disaggregate savings into components, which provides additional insight into the effectiveness of the individual savings measures. Although the method incorporates search techniques and multi-variable least-squares regression, it is easily implemented using data ...

A Decision Support System For Energy Efficient Propulsion, Mustafa Insel

MARENER 2017

Energy efficiency measures for cargo ships can be categorized into design and operation. Most of the design measures are based on hull form optimization, propulsion system selection and speed optimization. Operational measures are mainly based on selecting the optimized speed, trim, propeller pitch and rpm for energy efficiency. These measures should be applied onboard according to the loading conditions and weather conditions, such as wave height, period and direction, wind speed and direction. The variety of alternatives requires an online decision support system as the alternatives cannot be placed in a simple guideline or booklet. Such operational decision support systems ...
