Enhancing safety performance requires diligence and unrelenting effort. The Independent Safety Review Panels recently released report on the safety culture and practices at BPs U.S. refineries where a March 2005 explosion occurred in Texas City, Texas indicates similar failings are likely elsewhere in the industry. Learn what can be done to enhance continuous safety improvement.
Measuring flow rates and volumes of water and chemicals in the water, wastewater and chemical treatment industries requires the latest, simple to use and cost-effective technology that can keep up with the rigorous demands of the various applications.
Today, process data are readily available at many levels, from instrumentation to higher-level data historians and OPC servers. Choosing the right platform can be key to successfully implementing robust and maintainable process calculations at your company.
Understanding the fundamentals of fluid agitation can help meet the customers requirement and the processors need for efficiency. While portable mixers have been around for years, they often arent used to their full potential. Knowing the basics of mixing and flow patterns can help you get more out of your mixer.

Control's Béla Lipták continues his series on control of distillation processes, this time focusing on managing reboiler flow, temperature, feed rate, loading and reflux for economy, stability and safety.
ControlGlobal.com contributor David W. Spitzer provides a look from a process automation perspective at how magmeters and Venturi meters are vying with ultrasonics for clean and dirty water applications.
This article looks at six technologies mechanical floats and displacers, differential pressure, capacitance, ultrasonic, radar, and guided wave radar that are used most often for automated control, and provides practical guidance for choosing among them.
Properly accounting for how bulk solids actually will flow in a vessel or overall process can be crucial for successful operations. Learning some simple parameters can often provide a good sense of flowability.
ABB designed software for its ACS800 drive so Curtis-Toledo could improve the operation of its rotary-screw compressors. The customized software can control the system pressure, air delivery, oil temperature and duty cycle directly from the drive.
Companies, already having outsourced a lot of back office functions such as information technology (IT) and human resources management, now are targeting more central business functions, such as accounting and even R&D.
Removing water or moisture from a liquid stream is a critical operation in many processes. Liquid stream dryers commonly contain either molecular sieves or adsorbents; during the last 20 years, the use of molecular sieves has become much more common.
