Process Analytical Technologies for Representative Real Time Measurement of Conveyed Flows
DOI: 10.62178/sst.004.006
Abstract
Process analytical technologies (PAT) are utilised when continuous knowledge of quality is needed in a timely manner for bulk conveyed flows of matter, usually solid mixtures of highly varying heterogeneities. Reliable, representative monitoring of material quality variability is the target of implementing an online PAT solution, but the material variability itself also has significant effects on the measurement process performance. Many sampling and analytical procedure elements need to be competently designed, managed and controlled for any specific PAT solution. Conveyed bulk flows consist of materials with characteristics influencing their ability to be appropriately and effectively sampled. The value of the final data is to a large degree determined by its purpose for the PAT system user. This article covers the demands on real time measurement system management where material quality needs to be known with high confidence to influence the technological or industrial processes involved and allow subsequent decision-making. Every process is sensitive to some degree on the nature and specifics of its input parameters. The characteristics that affect online measurement performance cannot always be characterised in a manner like laboratory measurement systems, and various assessment approaches characterise competing system vendors. This article covers some technology opportunities and challenges applicable to conveyed flows that have proven beneficial in this PAT domain as outlined in many case study examples supplied and referenced.
