Will wearing dual protection an earmuff in addition to earplugs provide added protection against extreme noise levels? What are the pros and cons of using dual protection?
A limit alarm trip, known by many names, is a hardware device that monitors a process signal such as temperature, pressure, level, or flow and compares it against a preset limit. If the process signal moves to an undesirable high or low condition, the alarm activates a relay output to warn of trouble, provide on/off control, or institute an emergency shutdown.
The pressures to reduce costs and increase productivity in process manufacturing industries are unrelenting and are often labeled the top two enterprise-wide priorities for companies today. A seemingly logical consequence of the cost-cutting priority is the on-going practice of trimming operations and maintenance (O&M) staff allocations.
Conserve energy. Improve efficiencies. Lower production costs. Produce less waste. The list goes on. As energy and raw material costs have risen and had an impact on the production costs of most products, consumers, businesses, and engineers have become more conscientious about consuming resources.
Van Air Systems, Lake City, PA, is offering a new informational data sheet describing its compact HTR Series high inlet-temperature refrigerated air dryers.
East West Associates, Charlotte, NC, provides planning and project management services for companies establishing manufacturing operations in Asia, primarily China and Vietnam.
In recognition of the need for alarm management as a means to improve operating reliability and safety at the world's operating plants, the Instrument Society of America has entered into agreement with PAS Inc. to re-publish an alarm management handbook.
Plant engineers and maintenance personnel are facing tougher demands in the construction, maintenance, and upgrade of processing systems. The performance expectations for these systems are much higher than they were just 10 years ago.
Why have so many plants switched from the higher accuracy load cell to level probes and site glasses to determine the contents of tanks? Let's explore the most common reasons and, in the process, examine the root causes of many vessel weighing dilemmas.
Signs of global warming are all around us, from melting glaciers to stifling heat waves. The 10 hottest years on record have all occurred since 1990, and scientists say global warming is likely to disrupt water supplies, flood coastal areas, increase disease outbreaks, and cause fragile lands such as alpine meadows and coastal marshes to vanish.
Industriepark Oberbruch reflects an interesting concept in current investment philosophies for chemical companies expanding to Europe. It's a center for companies engaged in leading future technologies such as innovative new materials (e.g., carbon fibers) and fuel cells.
Polytetrafluoroethylene (PTFE) shaft seal bellows with vulcanized seams are withstanding damage from aromatic solvents on mills that blend paint ingredients at Rust-Oleum Corp.'s Wisconsin plant. The bellows have been in service for almost a year under conditions that caused previous seals to fail within days.
Ohio's Fairmount Minerals is one of the largest producers of industrial sand in the U.S., and its Illinois-based subsidiary, Wedron Silica, has been hard at work for more than a century. The sand is mined from the St. Peters Sandstone, which is a 200 million-year-old sand deposit that runs from Minnesota to Oklahoma.
Variations of the Paravisc modular mixing system from Ekato Corp. are being used for the production of pharmaceuticals, cosmetics, gels, toothpastes, shampoos, and foodstuffs as well as paste-like products such as adhesives, paints, and building materials.
Nanomaterial manufacturer nGimat may have accidentally found a solution to some of industry's biggest environmental problems. The company's ionic liquid solvents, stumbled upon during non-related precursor work, are now being developed to make industrial processes run cleaner and consume less energy.
