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.
The debate over the virtues of DCS vs. PLC has been ongoing since these two architectures came into existence 40 years ago. For certain industries, a distributed control system (DCS) provides substantially more value as the basis for automating the plant than a programmable logic controller (PLC)-based system. As functionality differences narrow and price points align, the debate over these virtues is getting more intense and the arguments for and against each system are getting more and more murky. This white paper discusses the “Top Ten” issues to consider when evaluating a DCS vs. building your own “DIY” distributed control system using a PLC-based architecture.
In recent years, TOC analysis has become accepted in the industry as the standard method and the only reliable online method used to determine contamination in waters, to control processes, to prevent product losses and to minimize waste. It is especially important to monitor this parameter in applications such as condensate return water, boiler/feed water, etc. In boiler/feed water and in industrial steam generating systems, carbonic acid corrosion of condensate lines is often a serious problem. Depending on the application type, analysis of only one parameter (e.g., TC) is generally not sufficient to make any useful process decisions. Multiple-parameter analysis (TOC, TC, TIC, VOC etc.), as carried out in the Hach BioTector B3500c analyzer, is proven to be more useful and always superior to single-parameter analysis in the industry.
Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the nonsettleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy. This paper reviews the most common stages for measuring and controlling dissolved oxygen in a wastewater treatment plant.
Chemical makers increasingly are focusing on water-related issues.

Energy consumption remains one of the largest controllable costs in oil refineries. Heat exchanger fouling can have a significant impact on energy efficiency and production loss. Asphaltene Precipitation is caused when refiners blend incompatible crudes. This is a major source of fouling and leads to performance limitations within days. Heat exchanger fouling is a major challenge for refinery operations. With the increase in crude blending from opportunity crudes such as tight oil, the traditional “manual” monitoring approach may no longer be effective. This White Paper discusses how on-line monitoring and analysis can enable refineries to:

The most commonly used compound in the chemical industry is water – not only as a solvent in processing, but also as an energy carrier in the cooling or heating cycle. As vast amounts of water are needed, chemical industries are often located close to large bodies of flowing water. Water used as processing or cooling water is cleaned and subsequently led back to the river or stream. For environmental protection, these waters are subject to specific control and monitoring measures. As the total organic carbon (TOC) non-specifically detects all organic compounds, this parameter has proven to be invaluable here. This booklet introduces a variety of industry-specific applications, and how Shimadzu can provide TOC analyzers to meet specific chemical application needs.
Solid-liquid separation is an instrumental part of chemical processing. To separate the solid particles, filter media made of textile or metallic materials and of composite materials are used as the basis for the filter cake. Often there will also be a washing process to improve the purity of the filter cake or to increase the yield of the liquid phase. Solid-liquid separation can be carried out in continuous or batch operation. There are many factors for selecting the right process filtration system for your specific application. This white paper reviews methods for identifying the right process filtration technology for your application and highlights case studies illustrating the methods discussed.
