Workshop 1: VALVE STICTION – DEFINITION, MODELLING, DETECTION AND QUANTIFICATION
Date: 25th July 2010 (Sunday)
Time: 1 to 4 pm
Venue: Riverview Hotel, Singapore
ABSTRACT
Stiction or high static friction is a common problem in spring-diaphragm type control valves, which are widely used in the process industry. Recently, there have been many attempts to understand, define, model and detect stiction in control valves. There are several methods for detecting stiction, but quantification of the actual amount of stiction still remains a challenge. This workshop will explain the mechanism of valve stiction, describe the severity of stiction problem in process industries and present the stiction modeling techniques. Then it will demonstrate and discuss the methods available for stiction detection and quantification along with their success and limitations. In order to demonstrate applicability of the available techniques, industrial data sets and industrial case studies will be used throughout the workshop. Most of the techniques are completely data-driven and developed based on routine operating data. Therefore, no additional excitation or experimentation of the plant is required.

For his outstanding research performance during the course of PhD program he has been awarded several awards such as University of Alberta PhD Dissertation Fellowship, Andrew Stewart Memorial Prize and ISA Educational Foundation Scholarship. He has published more than 30 journal and conference papers. Recently, he has published a book titled ‘Diagnosis of Process Nonlinearities and Valve Stiction’ from Springer-Verlag, Germany. He is a world expert in the area of Valve Stiction. He is the principal inventor of an international patent on “Methods for Detection and Quantification of Control Valve Stiction”. The methodologies and algorithms described in the patent are implemented in the commercial software ProcessDoctor from Matrikon Inc., Canada. His main research interests include diagnosis of poor control performance, stiction in control valves, data compression, control loop performance assessment and monitoring, and diagnosis of plant wide oscillations.
Workshop 2: PROCESS INTEGRATION FOR RESOURCE CONSERVATION
Date: 25th July 2010 (Sunday)
Time: 4 to 7 pm
Venue: Riverview Hotel, Singapore
ABSTRACT
Sustainable development and the rise of waste treatment cost are among reasons for carrying out resource conservation activities in the process industries. Process integration approaches such as pinch analysis and mathematical optimisation techniques are widely accepted as systematic design tools in synthesising optimum resource conservation networks (RCNs). In this workshop, several state-of-the-art process integration techniques for RCN synthesis will be presented. This includes pinch analysis and automated targeting techniques. Pinch analysis techniques make use of a two-stage approach, which involves identification of of minimum fresh resource and waste discharge (termed as targeting); followed by subsequent detailed design. On the other hand, automated targeting technique incorporates the targeting concept into mathematical optimisation framework for the identification of RCN targets. Various industrial case studies will be shown on how maximum recovery may be achieved for an optimum RCN.
