A new-type of polymer composite has recently been commercialized by Ceram Polymerik Pty Ltd. (Melbourne, Australia; edlinks.che.com/6517-533) for passive fire-protection applications. Passive fire protection consists of using a material or structure that confines fires, giving people more time to escape while reducing structural damage. The new composite is based on technology that transforms plastics and...

    The ANSI/ISA-S84.01-1996 standard, which has guided North American users for the past decade in designing safety instrumented systems (SIS) has migrated to a new international standard based on the IEC 61511 and is now known as ANSI/ISA-84.00.01-2004 (IEC 61511 Mod). Over the past few years, global chemical-process-industries (CPI) users have started to adopt this new standard, particularly...

    For many years, the job of a control room operator at a petroleum refinery or chemical plant was seen as relatively simple: Keep the process running and fix it when it breaks. That perception is changing as more operators take on additional responsibilities for improving energy usage and process efficiency while maximizing production. Meanwhile, many companies have reduced the number of...

    Among pilot plants, those in petrochemical or petroleum-refining service pose special risks of fire and/or explosion. The key strategies to minimize those risks are these: properly conducted preconstruction safety reviews; leaktight design and construction; close attention to area electrical classification; well-designed ventilation; well-planned storage; properly conducted maintenance; and...

    Liquids are accumulated and stored in tanks of various shapes and sizes throughout the chemical process industries (CPI). A small number of companies have made the design, fabrication and erection of these vessels their specialty. Initially, however, it is the process engineer who sizes and specifies tanks according to a specific application’s needs. In order to develop a data sheet for...

    Hydrogen is widely employed for hydrogenation and other purposes in chemicals manufacture, petroleum refining and other chemical process industries (Hydrogen: The Real Action Is Today, CE, February, pp. 28ff), and it holds promise as a fuel. However, this gas is highly explosive, prone to leakage and permeation, and difficult to detect, so special care must be taken during process engineering...

Phosgene is widely used for making fine chemicals, pharmaceutical intermediates, and polymers such as isocyanates, polyurethanes and polycarbonates. But phosgene is highly toxic, and although gas detectors are required to monitor for dangerous leaks, they cannot determine if workers have been exposed to low (below-threshold) concentrations over long periods of time, says...

Toshishige M. Suzuki and his colleagues at the Tohoku Center of National Institute of Advanced Industrial Science & Technology (AIST; Sendai, Japan; edlinks.che.com/5827-538) has developed a new analytical test strip that can quickly detect parts-per-billion (ppb) concentrations of heavy metal ions in water. Up to now, existing test strips for metal ions have not been sensitive enough to detect ppb...

    A direct link between the size of particles and their potential for causing health problems is what has the U.S. Environmental Protection Agency (EPA; Washington, D.C.; epa.gov) concerned about particulate matter (PM) that is 10µm in diameter or smaller. Renewed concerns have prompted the chemical process industries (CPI) to seek out more efficient dust-control systems that can handle...

The presence of arsenic minerals, such as enargite and tennantite, in some copper-bearing ore bodies, can be a problem for those wishing to recover the copper. When delivering copper concentrates to smelters in Australia, for example, miners are subjected to substantial penalties if...

    Solvents have been used for centuries and in all type of industries for the processing, manufacturing and formulation of goods. In the chemical process industries (CPI), solvents are used in various process-operation steps such as separation (of gas, liquid and/or solid), reaction (as reaction medium, reactant, and carrier), degreasing, washing and many more. As part of product formulations...

Last month, TÜV Anlagantechnik GmbH, Automation, Software and Information Technology (Cologne, Germany) granted protocol-type approval for the Fieldbus Foundation (FF; Austin, Tex.; edlinks.che.com/5826-541) safety-instrumented-systems (SIS) specifications. The specifications are in compliance with International Electrotechnical Commission (IEC) 61508 standard requirements up to, and including, safety...

Reader feedback tells us that maintaining process-plant safety is an area of perennial concern. That, doubtless, explains why Carolyn Merritt, chair and chief executive officer of the U.S. Chemical Safety and Hazard Investigation Board (CSB; Washington, D.C.), drew a large audience during her keynote address at the Chem Show in New York two months ago. For attendees of that Show who heard her, or who read...
