Proof testing - how this modern method improves efficiency, reduces errors, and meets compliance requirements
Process design and process safety are critical considerations in chemical production and processing. With design and safety paramount at the outset of any new development or equipment retrofit, firms can minimize risk exposure, maximize productivity and position themselves to remain compliant and competitive. Whether retrofit or new, chemical processing is continually challenged by combustible dust. Combustible dust can pose a hidden hazard when accumulation occurs in unseen locations such as in mechanical spaces, above false ceiling, ventilation systems and dust collection systems. In this Chemical Processing Powder eHandbook, we take a look at strategies and solutions for mitigating combustible dust hazards including:
Identifying hidden hazards - a case study outlining how a facility finds danger from accumulated dust and effectively addresses it
Powder flowability - how new measurement methods now make it easier to evaluate flow
Process safety - properly designed weigh model can optimize safety and improve efficiency
A multivariate approach to powder processing - an overview of several methods that can help determine which powder properties have the greatest influence on performance

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.
In the decade before Stuxnet attacked process control systems in Iran, there were just five known supervisory control and data acquisition (SCADA) vulnerabilities for all control systems in the world, according to the U.S. Department of Homeland Security's Industrial Control Systems Cyber Emergency Response Team (ICS-CERT). In 2011, the year after Stuxnet, that vulnerability count jumped to more than 215. Last year, it reached 248. No surprise then that Chemical makers are increasingly focusing on protecting their process control systems from intrusion both from the inside and outside.

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.
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:

Effectively mixing liquids and solids to create an optimal slurry is one of the perpetual challenges in the chemical industry. This case study demonstrates how an eductor-based mixing system can effectively handle a wide range of materials, utilizing the least amount of floor space, energy and human resources to achieve an optimized process. In addition, the eductor mixing system offers increased efficiencies over a conventional system of mixing by allowing solutions and slurries to be made on demand – as opposed to pre-mixed in large holding tanks. Another important benefit is the system limits exposure to operators, and mitigates issues of delivering solid material in a large vapor space. The design flexibility of an educator-based mixing system offers a high level of customization.
