For chemical processors, assuring safe operations is always top of mind. In this Chemical Processing Special Report we take a look at three distinct areas of operations and steps to insure best safety practices in each.
HIPS for Reactive Processes – how this safety-instrumented systems offer advantages over pressure relief valves
HART DIAGNOSTICS - in safety instrumented system (SIS) field devices have been used for many years by several different SIS vendors. HART diagnostics provide much more information on the health of a field device than can be determined from a standard 4–20 mA signal.
Proof testing - how this modern method improves efficiency, reduces errors, and meets compliance requirements
Economic growth, industrialization and population growth are driving the increasing demand for water, while factors such as climate change, pollution and regulation are affecting the supply and costs related to water.” The chemical industry, being highly water intensive, certainly is exposed to water-related risks. Any efforts to manage these risks and capitalize on opportunities begin with the measurement and appreciation of how water may impact business, followed by the development of strategies to protect the business both now and in the future. In this Chemical Processing Special Report we take a look at water challenges and potential solutions for chemical processors including:
Water-related risks and opportunities
How chemical makers strive to cut water consumption and improve treatment
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.
Medium voltage variable frequency drives (VFDs) are often the best choice to capitalize on opportunities to significantly reduce the operating and maintenance costs associated with relatively large rotating equipment. Even a seemingly modest energy savings of a few percent of the operating load can translate into significant energy savings. In this special report we take a look at how to make the most of VFDs: how optimum performance depends upon proper installation and control; how controlling the speed of VFDs can help eliminate waste and promote efficiency, reliability and quality and; considerations for changing drive speed over pumps.

In recent years, TOC analysis has become accepted in the industry as the standard method and the only reliable online method used to determine contamination in waters, to control processes, to prevent product losses and to minimize waste. It is especially important to monitor this parameter in applications such as condensate return water, boiler/feed water, etc. In boiler/feed water and in industrial steam generating systems, carbonic acid corrosion of condensate lines is often a serious problem. Depending on the application type, analysis of only one parameter (e.g., TC) is generally not sufficient to make any useful process decisions. Multiple-parameter analysis (TOC, TC, TIC, VOC etc.), as carried out in the Hach BioTector B3500c analyzer, is proven to be more useful and always superior to single-parameter analysis in the industry.
In the decade before Stuxnet attacked process control systems in Iran, there were just five known supervisory control and data acquisition (SCADA) vulnerabilities for all control systems in the world, according to the U.S. Department of Homeland Security’s Industrial Control Systems Cyber Emergency Response Team (ICS-CERT). In 2011, the year after Stuxnet, that vulnerability count jumped to more than 215. Last year, it reached 248 (Figure 1). No surprise then that Chemical makers are increasingly focusing on protecting their process control systems from intrusion both from the inside and outside.

Most chemical processors use precious-metal-bearing catalysts for facilitating and/or speeding chemical reactions. These catalysts are typically composed of platinum group metals (PGMs). After a number of process cycles the catalysts lose their efficacy and must be replaced with fresh catalysts. Spent catalysts are sent to a precious-metals refiner for recovery and refining of the valuable PGMs remaining in this material. Selecting—and working with—a precious-metals refiner is critical to ensure highest possible returns and peace of mind with regard to environmental concerns. Download and read this 22-page white paper to learn more about recovering precious metals from spent catalysts.
As the Department of Homeland Security (DHS) moves forward with the Chemical Facility Anti-Terrorism Standards (CFATS), the program continues to evolve.
