Hydrogen cyanide in amine systems
Mass transfer rate-based simulation has been used to study hydrogen cyanide ingress and accumulation in amine systems in unprecedented detail. In this article, the chemistry, prevention and possible mitigation using water washing arrangements and reflux purging are discussed quantitatively.
Address measurement challenges in sustainable aviation fuel production
Lipid-based conversion processes for sustainable aviation fuel are similar to fossil-based aviation fuel processes, but they have some critical differences. This article highlights the technical challenges associated with measuring and controlling biofuel-based aviation fuel processes, and provides suggestions to optimize conversion, while minimizing downtime and maintenance costs.
Brunei to Tokyo with hydrogen: A demonstration success story
The authors’ company has developed a novel technologya for the transport of large volumes of H2. This technology is based on the use of a liquid organic H2 carrier (LOHC) and utilizes both an “off-the-shelf” hydrogenation catalyst as well as a proprietary and now-proven dehydrogenation catalyst.
Plant maintenance and design
This article will review various maintenance activities, including emergency repairs, routine preventive and predictive maintenance, annual turnaround and computerized maintenance management.
Flare system design: Liquid pockets in flare headers
Flare and relief systems are the last line of defense against plant emergency overpressure and loss of containment. Therefore, the efficient design, management and maintenance of these systems are vital for safe operations throughout the lifecycle and operation of a plant. This article focuses on areas where major benefits can be achieved early in the front-end engineering design (FEED) stage of the project.
