  • Utilization of Renewable Energy via Thermochemistry

    Creator:
    Lei, Fuqiong
    Abstract:
    Utilization of solar energy or wind energy for electricity production is inherently challenging due to the diurnal and seasonal variations and normal intermittency. Effective, high efficiency storage methods need to be developed for further advancing renewable energy utilization. Endothermic chemical processing and thermochemical energy storage can be both employed as...

  • Dynamics and control of continuous crystallizers

    Creator:
    Leu, Lii-ping
    Abstract:
    The theoretical analysis of an unseeded, isothermal mixed-suspension mixed-product-removal (MSMPR) crystallizer with a fines trap is developed. The lumped parameter system equations are presented for a homogeneous nucleation and a number-dependent secondary-nucleation model. Linear stability analysis and system simulations are used to investigate the system's dynamic behavior. Modal control algorithms...

  • Simulation model of a total recycle urea process

    Creator:
    Yazhari, Faramarz
    Abstract:
    A steady-state computer simulation was developed for the Chemico Urea Process which is owned and operated by Reichhold Chemicals, Inc., St. Helens, Oregon. The DISCOSSA executive system was used to process information input and output and to automatically converge the complex recycle calculations in this process. The models developed in...

  • Inkjet-Printed Metal Halide Semiconductors for Wearable Electronics

    Creator:
    Li, Shujie
    Abstract:
    There is an emerging interest in developing wearable electronics as a platform, which provides the flexibility of a wearable while maintaining its promising functionality as smart textiles. Metal-halide semiconductors are attractive materials with tunable optical and electrical properties. Researchers have widely studied and applied it for advanced photonics and optoelectronic...

  • Process Intensification toward Reduced Exergy Destruction in Methane Upgrading

    Creator:
    Freiberg, Lucas J.
    Abstract:
    Exergy relates to thermodynamic value or usefulness in the universe. In this dissertation, three methods in the realm of "process intensification" are explored to reduce exergy destruction by equipment and processes that are used to convert and upgrade methane. Thermodynamic efficiency of a virtual heat exchanger is improved with a...

  • A steady-state, liquid-liquid contactor for experimental study of interphase mass transfer

    Creator:
    Hughes, Patrick Conan
    Abstract:
    A steady-state, liquid-liquid contactor, which was a modified version of a cell Previously developed by Godfrey, was constructed for the study of interphase mass transfer. In particular, the contactor was developed in order to eliminate problems encountered while studyinpg ternay systems with the conventional Lewis cell. The system, water-benzoic acid...

  • Solar-driven Dry Reforming Reaction in a Milli-scale Reactor

    Creator:
    Wang, Yige
    Abstract:
    Dry reforming of methane to syngas using CO2 was performed in a solar-driven milli-scale reactor, which converts solar energy to chemical energy. The process aims to upgrade the energy content of the feed stream using sustainable energy. The effect of mean residence time, temperature and CO2:CH4 ratio on conversion and...

  • Dynamics behavior of a cascade, cross-flow, packed column

    Creator:
    Golshani, Aboutaleb
    Abstract:
    The dynamics of a cross-flow, packed tower were investigated as a new alternative for gas-liquid contacting. At the present time there are two methods of gas-liquid contact, co-flow, and counter-flow, both having known limitations. This investigation studies cross-flow contact in an effort to eliminate the lower limits of gas-liquid flow...

  • Understanding Charge and Mass Transfer Phenomena in Functional Oxide Heterostructures

    Creator:
    Samarakoon, Widitha
    Abstract:
    Oxides are a versatile class of materials with a wide range of electronic, optical, and magnetic properties. This makes them ideal for use in a multitude of functional devices for oxide electronics, electrochemical conversion, and storage. The overall performance of these devices is governed by atomic scale charge and mass...
