These days, there seem to be more reasons than ever to change feedstocks throughout the chemical process industries (CPI). Whether environmental, or more directly based on financial and market drivers, big benefits usually require big changes. This is especially true in switching to many renewable feedstocks, which either add or compound challenges related to processing solids. When Columbia Forest...

Thermal insulation systems can provide several functions on piping and equipment in industrial facilities. Some of these are: reduction in energy loss, process control, personnel protection, emissions reduction, condensation, freeze protection, and noise reduction. In the chemical process industries (CPI), thermal insulation systems are often subjected to severe environments that might include either very...

Codexis (Redwood City, Calif.; www.codexis.com) and CO2 Solution (Quebec City, Canada; www.co2solution.com) have jointly developed a cost-effective method for capturing carbon dioxide from coal-fired power plants. Solvent-based systems for capturing CO2 are relatively well-understood, but they have not been widely deployed because they are energy-intensive and inefficient. Solvent-based approaches involve...

A magnetic composite based on reduced graphene oxide (RGO) has been developed by a Korean team with an exceptional capacity to remove arsenic from drinking water. The team, headed by professor Kwang S. Kim from the Center for Superfunctional Materials, Dept. of Chemistry, Pohang University of Science and Technology (www.postech.ac.kr), South Korea, claims the composite can achieve nearly complete removal...

Professor Kazuaki Ishihara and colleagues at Nagoya University (Nagoya, Japan;www.nubio.nagoya-u.ac.jp/indexe.HTM) has discovered an efficient, chiral, salt-based hypervalent iodine catalyst that could replace toxic metal catalysts without generating the waste or explosion risks associated with hypervalent organo-iodine complexes. The researchers took the radical step of swapping iodine bonded to carbon...

Photovoltaic cells typically operate at 20% efficiency in converting solar energy to electricity. A new system that could boost the efficiency to as much as 60% by combining the light and heat of solar radiation is being developed at Stanford University (Palo Alto, Calif.;www.stanford.edu). Standard silicon solar cells have two limitations, says Nick Melosh, an assistant professor of materials science and...

Last month, two significant cracks were found in the cornerstones of conventional thinking about how chemicals in the environment make their way into the human body and other living organisms, possibly leading to damaging effects. The timing is particularly apropos, as the first registration deadline of November 30 approaches for the EU’s regulation on Registration, Evaluation, Authorization and...

The deposition and accumulation of suspended and dissolved particles on membrane surfaces leads to performance loss. Fouling can dramatically reduce the efficiency and economic benefits of a membrane process. The type of fouling and how strongly it appears depends on several parameters, including the following: • Nature of solutes and solvents • Membrane process • Pore-size distribution...

Starting around 1970, many new contacting devices became available for use in distillation, absorption and stripping columns. Those devices included high-performance random packings, structured packings, high-capacity structured packings, augmented crossflow trays, counterflow trays and cocurrent flow trays. At the request of FRI’s membership, many of those devices were tested in FRI’s 4-ft and...

As potential threats continue to make headline news around the world, it is clear that the need for security measures is an ongoing process, and that this process requires vigilance. The chemical process industries (CPI) are considered part of the critical infrastructure in the U.S., and as such are regulated by the U.S. Dept. of Homeland Security (DHS; Washington, D.C.; www.dhs.gov) under the Chemical...

Athough the municipal water demand is considerably greater than that of industry, many of the municipal needs are addressed by relatively basic technologies, while industrial requirements can only be met with advanced treatment options. And, as industrial water demands continue to grow due to regulatory restrictions and mandates, water treatment providers are developing innovative desalination...
