Increasingly stringent clean air standards and heightened concerns over greenhouse gas emissions are driving technology enhancements in the chemical processing industry. This white paper explains some of the abatement challenges this industry faces and demonstrates how many chemical processors are integrating newer, more efficient emission control technologies for the destruction of Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs).
The paper also includes a case study, demonstrating how one Pure Terephthalic Acid (PTA) plant saved nearly one million dollars by upgrading to a newer thermal oxidizer technology.
With more demanding applications than most, chemical processing requires systems and infrastructure that can maintain efficiency and safety. Relative to flow, chemical processors need to address challenges such as corrosion, leak detection and mitigation, flow pressure and volume. In this Chemical Processing Flow eHandbook, we identify tips to improve flow including:
Distillation columns - how gravity-flow loop can enable measuring internal liquid flow in a column
The importance of the Process Design Basis
Flowmeters - monitor, detect and neutralize phosgene leaks
Polymer Piping - Material offers numerous benefits over metallic systems and spans various applications

Systems are becoming more complex. This complexity is changing the nature of the accidents and losses we are experiencing. 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. Advanced automation technologies continue to drive productivity improvements. In this Chemical Processing Improve Plant Safety eHandbook, we provide tips for safer processing including:
The role of senior management including six important steps senior management should take to insure safer processing
Optimizing process safety and efficiency through modern weighing design
The fundamentals of blast-resistant building

Welded vessels play a key role in most processes. However, few plants now have in-depth expertise in materials selection, fabrication and design of such vessels. As a result, plant staff often make errors that can be costly as well as compromise the suitability and life of the vessel. This three-part special report provides practical pointers that can help you avoid common mistakes and get the most appropriate, durable and cost-effective vessel.
Part 1 looks at a dozen important factors to consider in materials selection, including metal selection and appropriate use of corrosion allowances and coatings. It includes pointers gleaned from first-hand experiences that can help you avoid costly mistakes and delays.
Part 2 provides tips on how to avoid delays and achieve savings in the fabrication process. It also covers techniques that can improve vessel reliability and thus forestall costly repairs down the road.
Part 3 gets into design issues. It condenses the 5,000+ pages of the ASME Boiler and Pressure Vessel Code into a simple guide when specifying vessels, heat exchangers and tanks. It focuses on 10 key factors.

When thinking of the processing of chemicals, we think of any activity including storing, using, handling, manufacturing, or moving chemicals at a site, and any combination of these activities. A common state in many of these activities is the flow - or rate - at which the chemicals are moving through a process. Accurately measuring flow can be a challenge for many chemical processors since so many factors can influence the chemical properties and subsequently the rate of flow. In this Chemical Processing Pressure eHandbook, we discuss considerations for flow management including:
Pressure transmitters - how noise can pinpoint process problems
The use of orifice plates - how insufficient flow conditioning often undermines measurement accuracy
Robust Inferential Sensors - easier-to-develop-and-maintain sensors offer significant benefits for chemical processes

Even though thermal-fluid heating systems have been widely used for over 80 years, they still provoke a certain amount of fear and trepidation in users. This anxiety is reinforced by any number of horror stories that usually involve systems that suddenly develop a "problem" after years of trouble-free operation. This Chemical Processing Special Report: Make the Most of Heat Transfer Fluids delves in to the issues surrounding heat transfer fluids. Learn about:
Thermal fluids - dispel common myths about hot oil systems
Avert oxidation - how nitrogen can serve as an inert barrier to prevent heat-transfer fluid from contacting atmospheric air through the expansion tank
Steam vs. hot oil - a key tradeoff complicates the choice between steam and a hot oil system to heat water
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
