This 33-page paper discusses the wide variety of factors that can cause fouling and the impact of this fouling on the performance of a distillation column. It then provides details on practical methods for mitigating fouling, including equipment design, surface treatment, and use of additives.
This paper provides the viewpoint of the American Conference of Governmental Industrial Hygienists (ACGIH), a private not-for-profit, non-governmental corporation open to all industrial hygienists or other occupational health and safety professionals. The authors have the opinion that there are misunderstandings about the use of regulated health and safety standards.
In part one of this article, they provide some information on how regulations are formed and advice on using these values to conduct business. Employers and employees need this fundamental understanding to make informed health and safety decisions. This information is also useful for guiding public decisions about everyday toxic exposures.
This white paper discusses SONAR-based, clamp-on gas volume fraction meters which recently have been introduced to the industry that provide an accurate, real time, measurement of entrained gases. Coupling entrained gas volume fraction monitor with most types of process density meters, enables accurate determination of liquid and the liquid-solid components of aerated mixtures.
For years the industry has been talking green. But what real strides have been made? Will a Presidential Executive Order compel the industry to speed up efforts to actually go green? While pollution prevention was the original goal of green chemistry, todays efforts promise to have a substantial economic impact. This Special Report will bring you up to speed on fruitful efforts to go green including an update on the growing interest in bio-based feedstocks.
NELES rotary control valves with Q-Trim have greater capacity than comparable globe-style linear valves with noise reduction trims widening rangeability, reducing weight and valve dimensions, and a 50% cost reduction compared to linear valves of comparable Cv. NELES rotary control valves from Metso Automation. Intelligent Reliability leads to Intelligent Results.
Level measurement, which is the detection of the phase split between vapor/liquid, liquid/liquid, vapor/solid and even liquid/solid, is a key parameter in the operation and control of modern industrial processes. A reliable outcome depends on the phase conditions being relatively consistent under all process conditions. Unfortunately, the importance of level control isn’t always understood. Failure to measure level reliably has resulted in some of the most serious industrial accidents, including those at the Buncefield, U.K., fuel storage depot and BP’s Texas City refinery. In this Chemical Processing Level Management eHandbook, we discuss best practices for level management including:
How to Select the Right Liquid Level Sensor - It’s important to consider a variety of factors when choosing the type of technology
Properly Measure Liquid/Liquid Interfaces - Follow a simple rule for location of level gauge nozzles
Improve Reactor Vessel Measurement - Non-contact radar level meter speeds production and boosts worker safety

Companies can gain great insight into how their process operates, find problems, and improve quality by using process analytical software.
Process Analytics and Intelligencesometimes called Manufacturing Intelligencehas transformed the way companies produce goods, understand their manufacturing processes, and ensure a quality product in ways we could not have foreseen ten years ago.
This 10-page document discusses how the reference from the Center for Chemical Process Safety -- "Inherently Safer Chemical Processes, A Life Cycle Approach," 1st Edition, 1996 -- was updated in 2007.
Inherent Safety has been well received by industry, but there has been significant advancement in the concept of inherently safer design over the last 10 years. This overview highlights lessons learned and best practices in inherent safety.
One of the challenges that companies have faced in implementation of continuous monitoring systems is the lack of infrastructure for sensing and data collection. The devices to be monitored are widely dispersed throughout plants with large areas, have no existing power or signal transmitting wire infrastructure, so the capital costs associated with the power and communication services have historically prohibited continuous monitoring. This white paper will unearth best practices to prevent product loss, reduce emissions and ensure ROI.
20-page Sight Glass Application Handbook is a convenient reference for experienced engineers and a great primer for those new to sight glass selection. It offers a full overview of sight glasses for chemical processes, including types of glass, construction, lighting, installation and maintenance.
Automation systems today have become warehouses of knowledge and information. Beyond system configuration, years of effort is inevitably invested in them. This paper will discuss a few factors contributing to the automation knowledge crisis, present industry examples, and provide an optimal solution
Heat transfer fluids -- from mineral oils to synthetic and organic-based formulas -- are the lifeblood of many critical operations within the process industries. This special, interactive PDF looks at how plant personnel can better understand various fluids and fluid properties, and track the performance of their entire heat transfer system.
One of the trickiest materials to process, powders are comprised of solids or particulates, a continuous gaseous phase (usually air) and, almost always, a liquid component. Many factors influence powder composition including size and distribution, surface roughness and hardness. And, how powders are processed -- vibration, compaction, attrition, segregation -- can influence how powders react. In this Chemical Processing Powder eHandbook, we take a look at how to effectively handle powders, safer dryer operations and how to manage phase changes when processing powders.

Chemical Processing has taken an in-depth look at just industrial wastewater -- how it is used, processed and potential management and compiled a comprehensive Special Report titled: Make the Most of Water. This informative Special Report covers such topics as:
Is water the new carbon -- what path will regulating water take
How to optimize water use
Micropollutants -- defining, managing, and communicating potential risk
In chemicals processing, significant hazards exist -- such as those from fire, explosions or toxic release. The processes themselves, the chemicals being processed and the procedures followed, or lack thereof, can all contribute to the risk exposure of these hazards. What can processors do to mitigate these risks? For chemicals processors, it's crucial to implement processes and solutions to detect and prevent these hazards from occurring in the first place.
Chemical Processing has taken an in-depth look at plant safety -- how to identify the hazards and implement processes and procedures to ensure a safer working environment. This comprehensive Chemical Processing Special Report titled: Improve Plant Safety is now available to download for free.
One of the trickiest materials to process, solids are comprised of powders or particulates, a continuous gaseous phase (usually air) and, almost always, a liquid component. Processors that handle solids know only too well the types of throughput problems that come up on a recurring basis. Clumping; effective, economical and safe slurry mixing; dust management and dust explosion risk mitigation are all very real challenges faced by processors of solids. In this Chemical Processing Powder eHandbook, we take a look at how to effectively handle solids including:
Clumping – the 10 most common sources of agglomeration in bulk solids and how to effectively manage them
Strategies for optimal slurry mixing
