BP to cease production at Kwinana Refinery and convert to fuel ‎import terminal

bp Australia announced that it will cease fuel production at its Kwinana Refinery and ‎convert it to an import terminal, helping to ensure ongoing security of fuel supply for Western ‎Australia. The refinery, near Fremantle, has provided fuels for Western Australia…

Propionic Acid Production from Propionaldehyde

This column is based on “Propionic Acid Production from Propionaldehyde – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/propionic-acid-production-cost. Propionic acid (also known as propanoic acid) is a carboxylic acid commonly found in nature, mainly…

Software Powers the CPI

IIoT technologies have enabled software platforms that are more powerful than ever, but fundamental engineering principles are still at the heart of next-generation digital transformation It is clear that the emergence of industrial internet of things (IIoT) technologies has greatly…

Design of Bulk-Solids Moving-Bed Heat Exchangers

Presented here are equations governing heat transfer in a moving-bed heat exchanger, along with a numerical method for solving them Moving-bed heat exchangers (MBHE) represent an efficient method for heating or cooling bulk-solid materials compared to other technologies, such as…

A sandwich catalyst boosts H2 production

Platinum has been the main catalyst for hydrogen-producing reactions, but it has a low affinity for water molecules. This results in a slow rate of water electrolysis. Attempts have been made to combine metal-sulfide with platinum nanoparticles that promote water…

Thermodynamics of Gas Piping Systems

Understanding the implications of adiabatic and isothermal flow assumptions is necessary to have confidence in when to use such assumptions Every engineer uses assumptions because every analysis has an overabundance of variables to consider. Often, there are just too many…

First full integration of hydrogen production, distribution, storage and use is underway

The recently launched H2@Scale project is integrating a number of elements necessary for the commercial-scale integrated production and use of renewable hydrogen. Hosted by the University of Texas at Austin (www.utexas.edu) and funded through the Energy Efficiency and Renewable Energy…

Airset regulators for On/Off Valve Applications

Airset regulators are seemingly simple devices, but care must be taken to ensure the right devices are specified, particularly in safety instrumented systems Chemical plants and other heavy industrial facilities typically contain many pneumatically controlled valves, actuators and instruments. Airset…

Chementator Briefs

Ethylene Last month, Linde GmbH (Pullach, Germany; www.linde.com) and Shell (den Hague, the Netherlands; www.shell.com) announced an exclusive collaboration agreement on ethane-oxidative dehydrogenation (E-ODH) technology for ethylene production. The catalytic process is an alternative route to ethane steam cracking, offering…

A fast-acting, durable self-disinfecting polymer

A patented polymer material developed by Kraton Corp. (Houston; www.kraton.com) has shown rapid antimicrobial capabilities with expected long-lasting self-disinfecting efficacy. Currently pursuing regulatory review in the U.S. and other select countries for use as an antimicrobial agent, Biaxam is a…
