More attention to mercury and increased acceptance of predictive approaches is emerging. Such monitoring not only can keep plants on the right side of regulators but also can help provide insights for optimizing operation of equipment.
A computer simulation helps solve a refinery combustion problem. Finding ways to limit NOx from fired heaters, especially under stringent environmental regulations, has become a major concern for the petroleum refining industry. Complying with new stricter regulations, a Texas refinery upgraded the burners in one of its large cylindrical furnaces.
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.
Consider the impact of slope, fittings and valves. Plants can lose sizable amounts of money each year because of contamination caused in process lines. Owners and contractors alike can take steps in the design and construction phase to enhance the drainability and cleanability of a system.
This article addresses cost estimating for capital projects on which an analyzer system is installed, through start-up and commissioning of the project, to the resultant lifetime cost savings that can be gained.

A compact system significantly improves analyzer accuracy. This innovative turnkey solution for analyzer emissions is a solid-state pump with an ultra-sensitive pressure regulator that mixes a compatible gas with the analyzer samples to achieve a constant vent header pressure even during times of plant upset.
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.
