Bionext and its partners — a consortium of six industrial companies — have successfully completed the test program on BioTfueL demonstration units, setting the stage for commercialization of the thermochemical process that makes low-carbon-footprint sustainable aviation fuel (SAF) and other…
New electrochemical processes are being developed to help CPI companies reduce their carbon footprint For over a century, electrochemistry has played a crucial role in the chemical process industries (CPI), and many chemicals are still produced using traditional electrochemical processes,…
Adipic acid (hexanedioic acid; Figure 1) is among the most important aliphatic dicarboxylic acids, with about 2.5 billion kg produced annually. It is isolated as odorless, colorless crystals with an acidic taste. Adipic acid undergoes the reactions of carboxylic acids,…
Using a vast collection of experimental distillation-column data, sieve tray stability, and its influence on efficiency, are explored in terms of several physical and mechanical properties For trayed distillation columns, the concept of tray stability was introduced by the author…
Special considerations must be made for loading expensive solid catalyst materials into fixed-bed and tubular reactors Most units in the chemical process industries (CPI) use complex and expensive heterogeneous catalysts aimed at improving reaction performance. Although sometimes overlooked, the solids-handling…
Hydrogenation is an important reaction in many sectors of the chemical process industries (CPI), but H2 gas is not only expensive, its use requires considerable safety measures to prevent explosions. Significant cost savings could be achieved if hydrogenations did not…
Toxicology testing The world’s first toxicology-testing strategy without animal testing has been approved by the Organization for Economic Co-operation and Development (OECD; Paris, France; www.oecd.org). The testing strategy consists of three so-called alternative methods. They can be used to predict…
Next year, construction will begin on an industrial-scale pilot plant to further develop a new process that decomposes methane into H2 and carbon. The process uses a thermo-catalytic decomposition (TCD) technology developed by Hycamite TCD Technologies Oy (Kokkola, Finland; www.hycamite.com).…
Nitrogen (N2) makes up 78% of ambient air (20.95% of air is oxygen). N2 is an inert (non-flammable) gas used in industrial plants to prevent undesirable chemical reactions from occurring. Nitrogen is the most common inert gas used in the…
Successfully scaling up a mixing process involves understanding several important timescale parameters that can impact chemical reactions and equipment performance Many industrial processes are defined by rates. For example, rates of mass and heat transfer, rates of reaction and rates…
