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.

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. 

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. 

This article describes a method for the simultaneous separation of a mixture containing hydrogen, methane and carbon dioxide, which may result from certain shifted synthesis gas (syngas) mixtures.

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. 

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.
