Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings.
While continuing miniaturization and “rugged-ization” of the electronics are making the instrumentation circuitry more tolerant of the plant environment, the level of contamination in plant samples compared to laboratory samples continues to plague the process. This white paper reviews the factors in plant operation that may affect the deliverability of acceptable samples and provides guidelines for addressing these factors.
Oxygen measurement for safety and control is essential for process optimization in many chemical manufacturing processes. This white paper provides application details of probe-style TDL oxygen analyzers.
Precise process control strategies have accelerated the use of on-line chemical composition analyzers in plant applications. Contaminants in plant samples are the most frequent cause of problems with on-line analyzers. Trace contaminants can rapidly build up and cause instrument failure.
Implementation of rapid loss on drying and ash analyzers significantly reduces testing times associated with traditional methods, allowing companies to bring products to market faster, increasing production. These features will aide biomass material manufacturers in maximizing control of the market.
State Based Control is a plant automation control design based on the principle that all process facilities operate in recognized, definable Process States that represent a
variety of normal and abnormal conditions of the process. State Based Control, implemented with the latest developments in object-based technologies, delivers
direct benefits to its adopters in a variety of Operational Excellence categories. It results in productivity increases, higher asset utilization of both people and process,
automated responses and recovery for abnormal conditions and provides an environment for knowledge capture directly into the control design.
Proven methods for industry to reduce energy consumption and environmental impact are already at hand. These cost-effective solutions promise substantial return-on-investment now and in the future, without sacrificing performance or quality. For most companies and organizations, the answers to maintaining a competitive edge in this era of rising energy costs are readily available. By applying a suite of cost-effective power and automation solutions from technology leaders like ABB, these facilities can achieve substantial energy savings today without waiting for the "alternative fuels" of the future.
