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.
Salient points of a successful process plant execution
The aim of any successful project is to achieve consistent trouble-free operation at the rated capacity. Certain pinch points have been identified that must be addressed early in the process to avoid delays. These points are applicable for normal “stick-built” plants and not for plants with a high degree of modularization.
Revolutionize the integrated refining and petrochemical industries with digital twin models
Today’s refining and petrochemical complexes are increasingly adopting digital model technologies. One such tool, digital twins, has proven to be an excellent solution for the design and operational stages. With digital twin models, plants can achieve optimized business sustainability, improving environmental impacts, asset performance and financial criteria.
Enhance the performance of panel operators using a visualization tool in an LPG plant
Through a combination of case studies and practical insights, this article explores the benefits and challenges of implementing visualization tools in LPG plants. Moreover, it discusses strategies for optimizing operator training and workflow integration to maximize the effectiveness of these tools in improving operational performance, safety and overall plant productivity.
