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.

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

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.
