    Craig Knight, Asia-Pacific Digital Business and Customer Services Manager of Eastman Chemical Company, was given a mandate to sell Eastman’s philosophy for an integrated electronic supply chain, otherwise known as the Integrated System Solution (ISS), to its business partners in the region, and to encourage adoption. Having invested in a state-of-the-art technical architecture that would support interconnectivity with all parties along the supply chain, Eastman was keen to realize the full benefits to be gained from an integrated e-supply chain on a global scale. Following numerous rounds of discussion with key business partners in the Asia- Pacific region, some progress had been made. Nagase & Co., Ltd. of Japan had agreed to adopt ISS connections with Eastman, but had some reservations regarding the extent of integration. Although the benefits of integration were proven, suppliers, customers, distributors, and other interested parties were faced with numerous limitations and considerations that would have significant implications on their established business processes and even the shaping of their corporate strategy. Adoption was not a simple choice. Craig understood these shortcomings and was making every effort to ease the adoption process by identifying the longer-term benefits to Nagase and other business partners of applying XML technology to their businesses

    Advanced and novel modeling techniques for simulation, optimization and monitoring chemical engineering tasks with refinery and petrochemical unit applications

    Engineers predict, optimize, and monitor processes to improve safety and profitability. Models automate these tasks and determine precise solutions. This research studies and applies advanced and novel modeling techniques to automate and aid engineering decision-making. Advancements in computational ability have improved modeling software’s ability to mimic industrial problems. Simulations are increasingly used to explore new operating regimes and design new processes. In this work, we present a methodology for creating structured mathematical models, useful tips to simplify models, and a novel repair method to improve convergence by populating quality initial conditions for the simulation’s solver. A crude oil refinery application is presented including simulation, simplification tips, and the repair strategy implementation. A crude oil scheduling problem is also presented which can be integrated with production unit models. Recently, stochastic global optimization (SGO) has shown to have success of finding global optima to complex nonlinear processes. When performing SGO on simulations, model convergence can become an issue. The computational load can be decreased by 1) simplifying the model and 2) finding a synergy between the model solver repair strategy and optimization routine by using the initial conditions formulated as points to perturb the neighborhood being searched. Here, a simplifying technique to merging the crude oil scheduling problem and the vertically integrated online refinery production optimization is demonstrated. To optimize the refinery production a stochastic global optimization technique is employed. Process monitoring has been vastly enhanced through a data-driven modeling technique Principle Component Analysis. As opposed to first-principle models, which make assumptions about the structure of the model describing the process, data-driven techniques make no assumptions about the underlying relationships. Data-driven techniques search for a projection that displays data into a space easier to analyze. Feature extraction techniques, commonly dimensionality reduction techniques, have been explored fervidly to better capture nonlinear relationships. These techniques can extend data-driven modeling’s process-monitoring use to nonlinear processes. Here, we employ a novel nonlinear process-monitoring scheme, which utilizes Self-Organizing Maps. The novel techniques and implementation methodology are applied and implemented to a publically studied Tennessee Eastman Process and an industrial polymerization unit

    Novel Materials Used in Hydrogen Energy Economy

    The purpose of this study was to do some efforts in developing some novel polymer materials which could have the potential use in hydrogen pipelines and PEM fuel cell. In the project of developing hydrogen pipelines, sulfonated PET, sulfonated PET/Clay and PET/Clay were produced by the method of solvent-mixing. Characterizations with TEM, SAXS were made to determine the exfoliation degree of nanocomposites. TGA was carried out to measure the thermal stability, and hydrogen permeability was also taken in order to measure the H2 gas barrier performance. It was found that the addition of clay into S-PET or PET could decrease the hydrogen permeability in polymer nanocomposites. In the other project of polymer electrolye membrane in fuel cell, our research objective is to synthesize novel polymer electrolyte membrane (PEM) based on poly(1,3-cyclohexadiene) (PCHD) with outstanding potential for use in methanol fuel cells at temperatures well above 100 °C. After the consecutive crosslinking, aromatization and sulfonation reactions, or the consecutive crosslinking and sulfonation reactions, some novel PEM materials based on PCHD were synthesized. And a series of characterizations including FT-IR, elemental analysis, water-uptake, scanning electron microscopy (SEM), thermo gravimetric analysis (TGA), and proton conductivity were carried out
