Except for a few odd services, high liquid rate applications are typically the domain of either trays or random packings. Aside from the distributors, random packing designs are rather straightforward with the designer choosing the proper size to accommodate the fluid flow rates and achieve the desired efficiency. Trays, on the other hand, have a large variety of adjustable parameters and can be especially complex, especially when designed for high liquid rate applications.09/17/2007

Manufacturers of heat transfer fluids assign a maximum temperature rating to each fluid. This rating must be considered to ensure the safe and efficient operation of the fluid. This paper explains the basis of the rating, how fluids degrade, and how the temperature profile in a heat transfer system affects fluid performance and life.10/11/2004
A complete alarm philosophy document (APD) covers all elements, including design principles, KPIs and escalation policies. Creating an APD to outline these elements is the first step in a successful alarm management project. This paper provides an overview for the essential parts of a complete APD.10/13/2010
While the activity of alarm rationalization is straightforward, its application can range from simple to extremely complex depending on resources and objectives. This white paper introduces two basic methodologies: Bounded or Unbounded, and evaluates the benefits of each.10/07/2009
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
Working on your Site Security Plan (SSP)? The next stage in the Chemical Facility Anti-Terrorism Standards (CFATS) compliance process requires covered facilities to submit a SSP. Given the importance of the SSP, covered facilities should address a number of factors while they complete this step in the CFATS regulation.

Four dust collection system design improvements that can yield significant annual energy cost savings
The design and location of a dust collection systems hood, ducting, collector and fan can collectively add sufficient static pressure requirements to the point where larger, more expensive to operate motors are necessary to maintain effectiveness. Optimizing these areas can make it possible to use smaller, more energy efficient brake horsepower motors.02/19/2007

Industrial automation is no longer limited by the walls of a production facility. More and more automation is being handled via remote communication, whether its from the office or from the comfort of your own home. Todays PLCs give you the ability to access your control system to handle such tasks as monitoring via a website to determine the condition of a machine or check other statistics.04/24/2006
Finding the right pump for metering abrasive and aggressive chemicals can be challenging. The pump of choice needs to withstand harsh chemicals, accurately meter, and be simple to maintain and operate. More and more process engineers are turning to peristaltic pumps to solve their pumping problems, reducing life cycle costs and driving gains in process efficiency.05/07/2009
Harmonics can have a detrimental effect on power generators and other sensitive electrical equipment for the user and utility alike. The number of adjustable speed drives (ASDs) has increased significantly in the past decade. Their contribution to the total electrical load of a power system is significant and cannot be neglected. This white paper discusses various passive techniques for reducing input current harmonics.06/18/2007
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
