This paper reviews the basic techniques for dynamic modeling of these two key operations. It covers considerations related to heat transfer, reaction chemistry, mass balances and the control system. It also discusses equipment configurations, performance characteristics and operational constraints.09/08/2004
Sure, the process engineer is proud of his HMI (human machine interface) and the operations manager is pleased with his KPI (key performance indicators) dashboard and how effectively the system is running with the implementation of his new MES/MIS solution. The historian and analytic solution get all the credit when a field equipment crisis is averted. Does anyone ever think to thank the lowly driver? Without data, the HMI is just a pretty picture, and the best analytics in the world are only ideas without any basis in fact. Plus, tens or hundreds of thousand dollars are spent on that, while the driver budget isn't even a line item on the spec sheet. The communication arteries and veins reach out to all areas of the field equipment, sending and receiving data, efficiently and tirelessly ensuring the ability to acquire, analyze and adapt to the situations at hand.02/10/2009
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 solution02/15/2011
As the Department of Homeland Security (DHS) moves forward with the Chemical Facility Anti-Terrorism Standards (CFATS), the program continues to evolve. This white paper describes the ongoing CFATS compliance process (which is a combination of technical, procedural, and personnel security) and also provides insight regarding how to develop or revise a comprehensive Site Security Plan (SSP) and prepare for a CFATS Authorization Inspection (AI). Recommendations are relevant to SSPs for all tier levels and should be considered for a facility's initial SSP submission and/or any required SSP resubmission.

This 23-page white paper is from the Material Handling Institute's Classic Series and discusses the reliability of automated material handling systems.05/31/2005
This 34-page PDF white paper discusses the technology and performance-based standards implemented by the EPA during the last 10 years and how they will assist in removing harmful toxins from the air.06/28/2005
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.09/12/2014

Capacitance-type magnetic flowmeters have traditionally offered the advantage of having non-wetted electrodes and the ability to measure low conductivity fluids. However, they suffered from a sensitivity to flow noise and zero instability. Innovative technology overcomes these limitations and drives magnetic flowmeters into new areas of application, while reducing installed costs.07/18/2005
David A. Moore, PE, CSP, president and CEO of AcuTech Consulting Group, testified at a June 2006 hearing on Inherently Safer Technology in the Context of Chemical Site Security at The Senate Environment and Public Works Committee01/11/2010
The past two years have been a real wakeup call for the industrial automation industry. For the first time ever it has been the target of sophisticated cyber attacks like Stuxnet, Night Dragon and Duqu.
In addition, an unprecedented number of security vulnerabilities have been exposed in industrial control products and regulatory agencies are demanding compliance to complex and confusing regulations. Cyber security has quickly become a serious issue for professionals in the process and critical infrastructure industries.
If you are a process control engineer, an IT professional in a company with an automation division, or a business manager responsible for safety or security, you may be wondering how your organization can get moving on more robust cyber security practices.
In order to provide you with guidance in this area, Tofino Security and exida Consulting LLC have condensed material from numerous industry standards and best practice documents. They also combined experience in assessing the security of dozens of industrial control systems.
The result is an easy-to-follow 7-step process.02/28/2012

This paper discusses the problem of membrane fouling by antifoams, its leading causes and describes the development of a nonfouling antifoam for processes that use ultrafiltration downstream.09/22/2006
Before you order brand-new air-moving equipment to replace your worn, corroded, unbalanced equipment, consider the potential benefits of repairing or rebuilding that equipment.01/01/2007
Precious metals are often present in hydrocarbon, petrochemical, and chemical catalysts. Techniques for recovering precious metals have been around for many years; yet many catalyst owners have misconceptions about how their refining organizations work. In "The Five Myths of Refining Precious Metals", critical information is shared about the chemical processing industry:
- Crucial aspects of weighing
- Sampling and analysis of catalysts
- Methods of catalyst recovery
- What to look for in a proposal from a precious metals refiner
- Understanding the cost of quality
- How to ensure maximum precious metals return value
- Environmental, ethical, and regulatory compliance issues
The ever present emphasis on technological efficiency is just one of several forces behind the pressure on companies to "go green" despite a trying economy. The ultimate criterion that determines whether a motor is truly green is energy efficiency. Technology, long the key to efficiency, can help resolve this issue.03/08/2010

This white paper addresses the journey to achieve asset performance and reliability excellence. This begins with establishing sound fundamentals in terms of business practices, organization effectiveness and well deployed informational tools to support them.01/11/2007
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
EPA tracks emissions of six principal air pollutants - carbon monoxide, lead, nitrogen oxides, particulate matter, sulfur dioxide, and volatile organic compounds. All have decreased significantly since passage of the Clean Air Act in 1970 - except for nitrogen oxides.01/31/2006
