The ever-increasing cost of fuel and relentless push for environmental responsibility are constant factors in the profitability of many chemical process operations, and fluctuations in the prices of natural gas and other fuels can make it hard to predict future energy costs and the impact of such fluctuations on profits. However, the impact of fluctuating fuel costs, and the regulatory uncertainty related...

Polymeric piping systems have been used in well-defined segments of the chemical process industries (CPI) for decades. They have proven their sustainability to manage almost any chemical load up to temperatures of 100°C in the moderate pressure region ( p < 10 bar) if the choice of the respective piping-system material has been made correctly. However, their potential of exceptional performance is...

If the debate that culminated in passage of national healthcare reform in the U.S. is any indication of what is ahead for pharmaceutical manufacturers, they should ready themselves for battle. Implementation of the sweeping measure puts the onus on drugmakers to minimize waste and boost production of active pharmaceutical ingredients (APIs) and finished products, ensuring affordable healthcare for...

Temperature is a critical measurement in the chemical process industries (CPI). If a measurement is not accurate or reliable, or the sensor is incorrectly chosen, it can cost a company thousands of dollars in wasted steam, extra feedstock or rejected product. Sometimes even a few degrees of error in a temperature measurement can be very expensive. Therefore, it pays to ensure that temperature measurements...

A next-generation, carbon-enhanced membrane-bioreactor (MBR) system improves treatment of industrial wastewater with high organic content and containing compounds that resist microbial breakdown. The system allows economic reuse of wastewater or discharge to meet stringent environmental standards. The new MBR, dubbed EcoRight, will be commercially available in early 2011. First envisioned by Saudi Aramco...

Considering that a large fraction of the synthesis gas (syngas) produced today is made by steam reforming of natural gas, it might seem curious that in some parts of the world, syngas is being converted into substitute natural gas (SNG). Nevertheless, such role reversal is common where coal is abundant and gas is expensive. China, for example, imports most of its gas, either via pipeline from Russia or...

In any given chemical processing facility, there may be literally hundreds of operational environments that require protection from excessive pressure. Both rupture disks and pressure relief valves, or the two used in combination, help protect against damage to equipment and injury to personnel. While the basic technology for either type of mechanism has not changed much in recent years, tweaking the...
