Thermogravimetric analyzers (TGAs) deliver valuable information about a material’s response to temperature. But while the information they deliver is critical, TGAs themselves tend to be bulky and difficult to use, and can cost tens of thousands of dollars. This paper explores how you can gather the same data as a TGA using an instrument which is considerably easier to use, more durable, and less expensive: the Computrac MAX 5000XL. The materials examined in this paper are certain flue gas desulfurization byproducts—gypsum, calcium sulfite hemihydrate, and calcium hydroxide—but the principles in question can apply to all manner of materials, from biofuels to pet food to landfill waste.

For chemical processors industrial safety is a top concern. Industrial accidents can lead to lost production, injury and in some cases even death. This special report examines how organizations can reduce risk, prevent incidents and ensure safety and compliance in hazardous environments with improved processes. Topics covered include:
- How to Achieve Effective Process Safety Management (PSM) -- Senior managers play an important role in improving PSM. Their efforts should be visible and their leadership felt to ensure success.
- Getting To The Root Of Accidents -- Accident investigations usually focus on operator error or technical failures. However, applying systems thinking may provide greater insights on underlying causes and, in the long run, prevent more incidents.
- Optimizing Safety and Efficiency Through Modern Design-- This ignition protection method helps ensure accuracy, safety and compliance in hazardous environments
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.04/27/2015
Process Safety Management (PSM), driven by the OSHA 1910.119 standard, aims to prevent the unwanted release of hazardous chemicals.

For chemical processors, assuring safe operations is always top of mind. In this Chemical Processing Special Report we take a look at three distinct areas of operations and steps to insure best safety practices in each.
- HIPS for Reactive Processes – how this safety-instrumented systems offer advantages over pressure relief valves
- HART DIAGNOSTICS - in safety instrumented system (SIS) field devices have been used for many years by several different SIS vendors. HART diagnostics provide much more information on the health of a field device than can be determined from a standard 4–20 mA signal.
- 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.11/04/2014
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

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.07/15/2014
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:
- Better Understand Accelerated Fouling Due to Crude Incompatibilities
- Learn How to Use Online Monitoring to Detect Fouling
- Identify Which Tube Bundles Require Cleaning
Corrosion, leak detection and mitigation, flow pressure and volume are all factors that maintenance managers and other decision makers need to contend with as they manage flow at their chemical processing plants.

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.11/19/2013
