Multivariate statistical monitoring of a continuous slab caster. Proceedings American Control Conference 2002
Abstract: Principal components analysis (PCA) is a multivariate statistical (MVS) technology that can be applied in process monitoring and fault diagnosis. Dofasco has developed on-line multivariate statistical process control (SPC) monitoring systems for both its #1 and #2 continuous casters (#1CC & #2CC) based on this technology. The paper introduces the reader to the basic process of steel ...

A variable sampling interval S2-EWMA control chart for monitoring the process variance
This paper proposes a Variable Sampling Interval version of the Fixed Sampling Interval S2-EWMA control chart developed by Castagliola (2004) and dedicated to the monitoring of the sample variance of a process. In this paper, we explain how the various parameters of this VSI S2-EWMA control chart can be computed and how the use of the VSI feature significantly improves the statistical efficiency ...

Monitoring and modelling of the effects of process settings and screw geometry on melt pressure generation in polymer extrusion
Melt pressure is one of the most important process parameters in polymer extrusion and is closely related to product quality. However, it is not directly controllable and may be affected in a complex manner by changing other process operating conditions such as screw speed and barrel set temperatures. The ability to predict such parameters would be a powerful tool to aid process design and ...

Improved Aseptic Processes and Monitoring to Reduce FDA 483s
Abstract In recent years, the FDA response to companies with insufficient proof of control over their production has become more aggressive, demonstrated by the rise in 483s and warning letters issued. Topics related to environmental monitoring programs are included in the most common reasons 483s are issued. By becoming aware of the regulations and reasoning backing 483 distribution, ...

Radioisotopes applications in industry: an overview
Radioactive isotopes, particularly in the form of radiotracers and radioactive sealed sources, have been used over a broad spectrum of process industries for equipment and process troubleshooting, monitoring, control, inspection, optimisation and many other purposes. Radioisotope-based measurement techniques are best suited for multiphase flow systems encountered in industrial processes, since ...

Granularity determination of activated sludge through on-line profiles by means of case-based reasoning
Aerobic granulation from floccular sludge is difficult to detect in first stages with the naked eye. This work proposes a combination of multi-way principal components and case-based reasoning to predict the granulation state of a sequencing batch reactor, based solely on the on-line registered profiles of common sensors (i.e. pH, dissolved oxygen and oxidation-reduction potential). The ...

Moisture Audits & Analyser Performance Assessments at Woodside, Karratha - Case Study
Woodside had been experiencing intermittent blockages in 4/5 S1406 LNG trains since September 2008 and had been unable to pinpoint the source of the problems. Repeated hydrate formations were leading to reduced productivity and the existing process monitoring instrumentation had failed to confirm moisture breakthrough on the beds. The site's existing Panametrics portable moisture analysers had ...

Developing the "right" breakthrough product/service: an umbrella methodology - Part A
Breakthrough products and services (BTP/S) have been found to contribute significantly to corporate profits and market position. However, because such products are designed to meet needs that may not yet be apparent in the market and have no historical point of reference, traditional market forecasting techniques are unable to provide accurate predictions of market success for them. An ...

Improved real-time data anomaly detection using context classification
The number of automated measuring and reporting systems used in water distribution and sewer systems is dramatically increasing and, as a consequence, so is the volume of data acquired. Since real-time data is likely to contain a certain amount of anomalous values and data acquisition equipment is not perfect, it is essential to equip the SCADA (Supervisory Control and Data Acquisition) system ...
