| Abstract Scope |
For over six decades, laser-induced ablation and plasma spectroscopy (nowadays more commonly known as laser-induced breakdown spectroscopy or LIBS) has been recognized as a promising approach for online or inline chemical analysis of molten metal for improved process control. It is only in the past 5 years, however, that this technology has started gaining a foothold in the aluminum industry. The main drivers for this change include an increased focus on process automation and plant safety, with key enablers being recent advances in optical technologies and an improved understanding of atomic emission from laser-induced plasma generated at molten metal surfaces. Moving chemical analysis from laboratories to the often harsh conditions of the plant floor of primary or secondary aluminum smelters, while maintaining the required levels of repeatability and accuracy, represents significant engineering challenges. Experiences from plant installations across the value chain, ranging from primary production to recycling, will be discussed. |
