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...

Improved C5 use Some 106,000 ton/yr of so-called spent C5 fraction is generated at Mitsui Chemicals Inc.’s (Mitsui; Tokyo, Japan; www.mitsuichem.com) naphtha cracker at its Chiba Factory. Presently, the company is selling about half of the C5 fraction (50,000 ton/yr) — after partial hydrogenation — to Idemitsu Kosan Co. (Tokyo) for gasoline production, and the remainder is burned as fuel...

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...

A metal membrane system developed by Eltron Research and Development (Boulder, Colo., www.eltronresearch.com) separates hydrogen from mixed-gas feed streams that result from gasification, steam reforming and petrochemical processes. Based on a proprietary, dense metal alloy with hydrogen permeability that is coated on both sides with catalyst material, the membrane can be used as a carbon capture method...

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...
