Bob Katin, chairman of the California Government Relations Committee of the American Institute of Chemical Engineers (AIChE) and president of the California Legislative Council of Professional Engineers (CLCPE), is a persistent man. For more than 20 years he has fought to change the California Professional Engineers Act (PE Act) so that chemical engineers would have parity with civil engineers. In the...

Because many of their products go directly to the ultimate end user, polymer and plastic processors are being asked to make their final products safer. Both consumers and governments alike are demanding that plastics, especially those that are destined for food contact, contain lower residual solvent and monomer levels. At the same time, the biopolymer industry is exploding and processors want to get in on...

Unlike fossil fuels or precious metals, phosphorus has no alternatives — we (and all other life forms on the planet) need phosphorus; it’s in our DNA, our bones and our energy-producing chemicals (ATP). We get it from our food — meat, grains and vegetables — so it’s not surprising that phosphorus is a key ingredient in fertilizer, as well as a component of sewage, manure and...

Whether for pumping, mixing, compression or ventilation, motors are used everywhere in the chemical process industries (CPI). Unfortunately, they are notoriously energy intensive, accounting for about 65% of the electrical consumption of a chemical production site. However, with the world, especially the U.S. and Europe, turning a watchful eye on energy consumption, motor and drive manufacturers are...

In the processing environment, powders often appear to exhibit variable flow behavior, which can be the cause of significant inefficiency in the form of unplanned shut downs or compromised product quality. However, the reality is that powder flow properties are influenced by a diverse array of parameters from air and moisture content to particle size, shape and surface charge.  Figure 1. The new...

While almost all chemical processors employ simulation software during the early design stages of new plants or new lines, simulation vendors say best-in-class facilities take the powerful tools further and use them for improving operations and profitability. And, across the board, software providers are working hard to make their most recent applications more user-friendly and accessible, so that more...

A number of factors, including plans for new plants and expansions, as well as the retirements of experienced personnel, are creating an especially competitive labor market for engineers and technical workers in the chemical process industries (CPI). The situation is placing upward pressure on salaries for chemical engineers, but continues to challenge companies in the area of knowledge management and...

For every chemical process there are different pressure measurement requirements. Some demand devices that are compatible with a unique chemistry, others require pressure instrumentation that won’t pose a risk to workers or processes and many call for instruments that can handle a wide temperature range. However, throughout the chemical process industries (CPI), there are a few items on...

Today’s chemical processors must cope with rising labor costs, increasing global competition, escalating fuel costs and more-stringent safety and environmental regulations. To improve productivity and reduce costs in today’s competitive environment, many facilities are operating leaner than even before. And, downsizing strategies have seen the reduction of maintenance staff, which often results...

Increasing production of natural gas from hydraulic fracturing of shale deposits has fundamentally altered the landscape of chemical production in North America. The higher margins on steam-cracking ethane to produce ethylene have resulted in significant feedstock shifts in the U.S. over the past two years. Numerous chemical producers are expanding ethylene capacity to take advantage of the increased...

It was clear at the recent Chemical Sector Security Summit (Baltimore, Md., July 31-Aug. 1) that awareness of and activity in security for the chemical process industries (CPI) are growing. The annual summit, now in its sixth year, was held at its largest venue ever and brought together about 650 participants from industry, academia and the government to network with other security professionals, share...

Though times are changing, many of the traditional challenges associated with running a chemical processing plant remain the same. For years processors have been asking for leak-proof, high-performance valves, but it is only recently that valve manufacturers are employing new technologies, designs and materials that improve performance and reduce leaks.   Improved Cv values “Traditionally...

Sometimes the smallest parts — such as seals and gaskets — can have the greatest impact on plant performance. For this reason, seal and gasket manufacturers are developing innovative new materials and designs that will help these diminutive, but important, components stand up to the harsh operating conditions of the chemical process industries (CPI). “With multiple seals and gaskets...

It probably isn’t going to solve all the world’s energy needs, but producing biogas from waste can help slash the energy bills at some production plants, sewage-treatment plants and even farms. And for those companies offering biogas technology, business is booming. For example, Eisenmann Anlagenbau AG & Co. KG (Böblingen, Germany; www.eisenmann.com) has been active in the biogas...

There might be as many categories of catalysts as there are chemical processing applications. And, no matter what the specialty or application, most catalyst producers are in a constant state of research and development in order to meet the demands of their chemical processing customers, as well as to develop innovative catalysts for new applications and growing market areas. Recent efforts of some of the...

An explosion is defined as “a rapid increase in volume and release of energy in an extreme manner,” and is usually accompanied by high temperature generation and gas release. Flammable gases, vapors, dusts and ambient oxygen — all present in chemical processing facilities — can react to cause an explosion that essentially creates a shock wave. As a result of modern production...

Adsorption and absorption play a big role in reducing air pollution in many applications around the world. Studies show that the largest single use of absorbers this year will be to capture SO2 from power-plant flue gas. Adsorbers will be used by many chemical process industries (CPI) to capture volatile organic compounds (VOCs) and odors. A small, but fast growing industrial segment uses ozone and...
