AIChE CAST Division Newsletter Spring 2014


Change in Editorial Team

We begin this newsletter by thanking Peter Rony and Karl Schnelle for serving as co-editors of the CAST newsletter. As described in the Summer 2013 Newsletter, Peter has served as newsletter editor for 27 years. Everyone in CAST appreciates Peter's work, particularly because the archived newsletters serve the important purpose of recording the history of the division and keeping our community informed and engaged.

With Peter's stepping down as editor and Karl taking on the position of CAST 2nd Vice Chair, the CAST executive committtee entrusted Laksh with the responsibility of contributing as the Publications Board Chair. Together, we will be building on the excellent work done by Peter and Karl. We will start off our work with the existing format but will transition to more multimedia-enriched and interactive newsletter over the next few editions. We look forward to your contributions and continued support for the newsletter.

CAST 2013 Plenary Talks

Included below is a summary of the CAST Division plenary talks given at the AIChE Annual Meeting, San Francisco, USA (November 2013).

1. Paper Title: CAST Division Overview (Paper 46a; Slides used in this talk can be accessed here)

2. Paper Title: Superstructure-based shale plays water management optimization (Paper 46b; Presentation Slides)

Authors: Linlin Yang (Carnegie Mellon University, USA), Jeremy Manno (Carrizo Oil & Gas) and Ignacio E. Grossmann (Carnegie Mellon University, USA)

Abstract: Water use makes up approximately 10% of the overall shale gas drilling and completion costs. Even though the Marcellus Shale Play overlies a water-rich region, regulatory restrictions pose considerable logistics challenges that demand sophisticated management strategies. There are four key aspects for water use in hydraulic fracturing, including source water acquisition, wastewater production, reuse and recycle, and subsequent transportation, storage, and disposal. The difficulty with surface water acquisition is that withdrawal is only permitted if the minimum flowrate requirement is met. Once a well is fractured, there is considerable flowback water. The total dissolved solids (TDS) concentration in the flowback water is the key criterion for determining the volume of freshwater to be blended to make up the source water used for the next fracture. The flowback water can be recycle reused or disposed. Of these options, disposal is not economically viable since it requires transporting wastewater to Ohio. In addition, transportation is a major expense since ninety percent of the trucks required for the completion of a wellpad are associated with the fracturing process. Alternatively, permanent or temporary piping could be considered. Finally, water storage is also heavily regulated, making storage of wastewater undesirable.

This presentation optimizes water use life cycle for wellpads through a mixed-integer linear programming (MILP) discrete-time representation. The objective is to minimize transportation, treatment, storage, and disposal cost. Assuming freshwater sources, wellpads, and treatment facilities are given, the goal is to determine an optimal fracturing schedule. The formulation involves a large number of binary variables mainly due to the long time horizon under consideration. Several examples are presented to illustrate the effectiveness of the formulation and to identify additional optimization opportunities that can improve the economics of water use.

3. Paper Title: A Stochastic PDE Framework for Natural Gas Network Operations (Paper 46d; Presentation Slides)

Author: Victor M. Zavala (Argonne National Laboratory and University of Chicago)

Abstract: We present a stochastic optimal control model to optimize gas network inventories in the face of system uncertainties. The model captures detailed network dynamics and operational constraints and uses a weighted risk-mean objective. We perform a degrees-of-freedom analysis to assess operational flexibility and to determine conditions for model consistency. We compare the control policies obtained with the stochastic model against those of deterministic and robust counterparts. In addition, we demonstrate that the use of risk metrics can help operators to systematically mitigate system volatility. Moreover, we discuss computational scalability issues and effects of discretization resolution on economic performance.

4. Paper Title: Study of Mechano-Electric Feedback On Cardiac Wave Propagation (Paper 46e; Presentation Slides)

Authors: Azzam Hazim, Youssef Belmhadia and Stevan Dubljevic (University of Alberta, Canada)

Abstract: Electrical alternans is a physiological phenomenon that is a beat-to-beat oscillation (alternation) of the cardiac Action Potential Duration (APD). Alternans have been shown to be a precursor to arrhythmias (Makarov L et al., 2010) and sudden cardiac death (SCD), which is the most common cause of death in the industrialized world. The presence of electrical alternans induces, through the mechanism of the excitation-contraction coupling (ECC), an alternation in the heart muscle contractile activity. Contraction of cardiac tissue also affects the process of cardiac electric wave propagation through the mechanism of so called mechano-electrical feedback (MEF) (Kiseleva I et al.,2000). The study of mechano-electrical feedback is an important direction of research in current cardiac electrophysiology.

A valuable method to study mechano-electrical feedback is mathematical modeling allowing the study of the coupled mechanical and electrical activity of the heart tissue. In our study, we use the Nash-Panfilov (NP) model (Nash and Panfilov, 2004), which describes electro-mechanical coupling in a 3D isotropic cardiac tissue at the most basic level. The Mooney-Rivlin material response is used to describe passive mechanical properties of the cardiac tissue. The coupled model includes an additional variable to represent the active stress which is responsible for mechanical deformation and is coupled to the stress equilibrium equations (Nash and Panfilov, 2004; Alvarez-Lacalle and Echebarria, 2009). The active and passive stress components are linearly superimposed to define the total state of stress in the tissue.

In this work, numerical examples are provided to illustrate the effects of mechanical deformation (perturbation) on wave propagation. This will serve to demonstrate that a significant contribution to the physiological and contractile tissue features is linked through the tissue mechanics as an underlying mechanism through the mechano-electric feedback. In addition, we will explore the possibility of cardiac alternans annihilation by applied mechanical perturbation.

5. Paper Title: Real-time Particle Size Estimation for Crystallization Processes through GPU-based Multivariate Image Analysis (Paper 46f; Presentation Slides)

Authors: Mai Chan Lau (National University of Singapore, Singapore) & Rajagopalan Srinivasan (Indian Institute of Technology, Gandhinagar, India)

Abstract: The capability to estimate crystal size distribution in real-time is important for effective control and optimization of particulate processes. Appropriately controlled crystal size distribution not only ensures high efficiency of downstream operations like filtering, drying and formulation, it also safeguards the efficacy of final product which is in crystal form. In order to achieve fast online measurement of crystal size, automated image analysis has recently been developed (Sarkar 2009). The methods have been shown to be quite accurate in terms of the particle size distribution estimated in real-time.  However, this comes at the cost of computational efficiency. The major objective of the current work is to improve the computational efficiency of multivariate image analysis (MIA) such that the computational speed is at least on par with the image generation speed.
