For many years now, talk of wirelessly networking and transmitting process signals has projected new levels in process performance, safety and overall efficiency for the chemical process industries (CPI). Until recently, however, a number of strings held back widescale adoption. Those strings are finally unravelling, and there is concrete evidence to prove it. Figure 1. WirelessHART adapters provide access...

Among the most pressing concerns for the chemical process industries (CPI) are weathering the global economic recession and dealing with anticipated carbon emissions regulations. Switching from oil and gas to biomass for fuel in a CPI plant is a relatively simple way to ratchet down greenhouse gas emissions and cut costs simultaneously. Biomass fuels can help cut operating costs, improve fuel flexibility...

A continued economic contraction remains the dominant feature of the employment landscape for chemical engineers, with fewer job openings and choosier corporate hiring processes, but chemical engineering salaries are strong, according to those closest to the chemical engineering job front. Despite overall job losses in the chemical process industries (CPI), demand for creative chemical engineers with broad...

As the chemical process industries (CPI) continue to battle with cost containment, labor cost management and maintenance cost issues, there is additional pressure on engineering and maintenance staffs to deploy resources where they are needed the most. Though small in stature, pressure transmitters can actually play a sizeable role in this type of process optimization. The reason is simple. Both pressure...

Security at many U.S. chemical facilities is currently regulated by the U.S. Department of Homeland Security (DHS; Washington, D.C.; under the Chemical Facility Anti-Terrorism Standard (CFATS). This rule, however, is about to expire this month, October 2009. All expectations are that CFATS will be extended for a year, while proposed modifications to the standard continue to be debated in the...

Efforts toward large-scale production of lithium-ion (Li-ion)-based car batteries got a big boost in early August, when the Obama Administration announced $2.4 billion in U.S. government investment aimed, in part, at dramatically ramping up the supply chain for advanced batteries for the auto industry. A majority of this funding is funneling directly into the chemical process industries (CPI), which are...

By definition, integrated safety instrumented systems (SIS) have the potential to reduce risks. But recent advancement is also enabling the use of more sophisticated instruments and tools that can benefit the process. For these reasons, integrated control and safety systems (ICSS) are receiving recognition across the chemical process industries (CPI). “There have been developments from a technology...

Substantial technological advances to meet the growing regulatory scrutiny of a wide variety of pollutants have taken place over the past 50 years. In the last few years, the increased complexity in regulations in developed countries has been even more accelerated, challenging the chemical process industries (CPI) and their suppliers of air-monitoring equipment to reach new heights. In addition, developing...

On Sunday morning before the start of Achema 2009 (May 11–15; Frankfurt, Germay) — organizers of the world’s largest exhibition and congress on chemical engineering and biotechnology, Dechema e.V. (Frankfurt;, as well as industry experts participating in the traditional press conference, were somewhat edgy. Even though the ten halls’ 134,000 m2 of exhibition space...

“When you improve the efficiency or capacity of a product, it almost always can be used to improve the process economics with respect to investment costs or operating costs,” says Mark Pilling, manager of technology with Sulzer Chemtech (Tulsa, Okla.). To help processors do this, separation-technology providers strive to maintain a strong base of engineering expertise to assist customers in...

With traditional petroleum-derived feedstocks facing relentless economic and environmental pressures, it’s no surprise that stakeholders throughout the chemical process industries (CPI) have been in hot pursuit of alternative routes for producing commodity and specialty chemicals and polymers from cheap, plentiful renewable feedstocks. The most promising routes are based on agriculturally derived...

Today, stakeholders seeking to produce platform chemicals from renewable feedstocks are evaluating competing routes — based on, for example, oxidation, reduction, selective bond breaking, selective bond formation, and the selective dehydration of sugars — for breaking down complex starting materials into simpler, more versatile building block molecules. “The focus of this approach is to zero in on a...*_4841.html

Because of the difficulties associated with separating it from lignocellulosic feedstocks, “lignin has typically been burned by papermakers to produce process heat or power. This is a tragic waste of a good source of carbon,” says Joseph J. Bozell, associate professor, Biomass Chemistry, Forest Products Center, University of Tennessee (Knoxville). Though challenging, the use of lignin to...*_4842.html

Dow is currently building a 770-million-lb/yr train to produce Dowlex linear low-density polyethylene (LLDPE) in the middle of a sugar cane field in Brazil. Once online, the unit will be the first fully integrated sugar-cane-to-polyethylene complex in the world, according to the company. In the process, sugarcane juice is fermented, centrifuged and distilled to produce ethanol, which is then converted into...*_4843.html

Petroleum refiners throughout the world are faced with increasing uncertainty regarding future refining margins, crude prices and project costs. These factors, along with falling demand for refined products, a global recession, and tighter credit markets, are forcing global refiners to reconsider, postpone, or cancel expansion projects. At the same time, mandated reduction of sulfur levels in refined...

As it is with all chemical processors, the current economic climate is forcing batch processors to produce more saleable product at a better profit margin from the same assets. Increasing flexibility, reliability and visibility while decreasing batch cycle times via integrated automation systems can help increase throughput and the chance of survival. Staying afloat Figure 1.  Many batch automation...

Strategies for extracting more distillate from petroleum to meet the growing demand for diesel fuel constituted a major theme of the recent annual meeting of the National Petrochemical and Petroleum Refiners Association (NPRA, Washington D.C.; in San Antonio, Tex. Worldwide, the demand for distillate is expected to increase by more than 5 million bbl/d over the next 10 years, says Richard...
