  • Optical System Sets New Standards in Oxygen Measurements

    Optical Dissolved Oxygen Measurement in Power and Boiler Applications

    Over the past decade a few trends have started to gain pace within the industry, driving a change in instrumentation requirements for operations managers and plant chemists:

    • Maintenance and operations budget cuts have resulted in fewer plant personnel, forcing plant staff to optimize their workload even further
    • As the cost of building new power and boiler systems increase, many operators now look to plant life extensions as a solution to bridge gaps in production capacity at a lower investment premium

    These trends have changed the requirements in these applications. Starting from these trends, this article analyzes the options for oxygen measurements that are precise, reliable, stable, and above all require low to zero maintenance.

  • Filtering Samples to On-Line Process Analyzers

    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.

  • Special Report: Protect Process Control Systems

    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. In this Chemical Processing Special Report: Protect Process Control Systems, we take a look at:

    • How to better protect your control system - "Defense in depth" is crucial, and new and maturing technologies may help
    • Cyber Security Challenges - learn about countermeasures to protect control systems
    • Case Study: A vulnerability assessment reveals critical gaps in the security of a natural gas pipeline
    • How to mitigate security risks in legacy process control systems  - several steps can help protect against threats and extend the life of legacy equipment

  • Tank Blanketing in Hydrocarbon Processing Facilities

    During industrial manufacturing, many companies use a wide variety of chemicals from methanol, acetone and benzene to foodstuffs like wine and edible oils stored in large tanks at different points in the manufacturing process. In a technique called “chemical tank blanketing,” or “padding” nitrogen is commonly applied to protect chemicals stored in tanks against contamination, degradation or chemical change as well as to prevent fire or explosions. This white paper first discusses blanketing basics and benefits. It reviews considerations for tank blanketing  systems and discusses a newer approach, which is typically more  cost effective for most applications, is that of generating nitrogen on-demand in the plant itself.

  • Research Paper: Investigating the Relationship between Gypsum Purity and Hydrogen Sulfide Production under Anaerobic Conditions

    Calcium Sulfate (CaSO4) more commonly known as gypsum is a naturally occurring white crystalline mineral that has many different uses and applications. Gypsum in its hydrated form (CaSO4•2H2O) is used in the construction industry for fire resistance in buildings. Outside of the construction industry, gypsum is used in the food and fertilizer industry for calcium and sulfate fortification respectively. When gypsum is no longer usable, it is deposited in construction and demolition(C&D) landfills where anaerobic (low oxygen) conditions and the presence of sulfate-reducing bacteria promote the decomposition of wallboard/gypsum into hydrogen sulfide gas (H2S). Due to local and state regulations on odor control, these C&D sites monitor their fill for hydrogen sulfide gas.  This paper will couple two methods of analysis to observe the relationship between the purity of gypsum (calcium sulfate dihydrate) and hydrogen sulfide concentration as a sample is fermented by sulfate-reducing agents (e.g. bacteria). The scope of this research may be beneficial for industrial hygienists concerned with C&D landfill H2S levels or for incoming gypsum processing plants who suspect poor quality gypsum.

  • The Perils of a DIY Distributed Control System

    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.

  • Save Money, Time, and Water With Rotary Impingement Tank Cleaning

    Tank cleaning has always been viewed as a necessary evil for manufacturers. During the cleaning process, a significant amount of resources (time, chemicals, water, electric and labor) is required between batches to ensure a reliable, uncontaminated, quality batch is produced. Although these repeating expenditures have a significant effect on the bottom line, many chemical manufacturers continue to rely on outdated processing for cleaning, not realizing the potential opportunity for substantial cost reductions and revenue recovery through CIP optimization.This whitepaper includes specific case studies on the benefits of rotary impingement and CIP optimization vs. the standard tank cleaning processes. These benefits include drastic savings in time and water usage as well as employee safety.
