The world is increasingly turning its attention to alternative fuels in the quest for net-zero emissions, and hydrogen (H2) is at the forefront of this transformative shift. This article will discuss the benefits of H2, comparisons to alternative energies, sustainability and environmental implications, and H2’s potential. 

This article examines the application of solvent absorption-based post combustion capture for refinery/site-specific factors and quantifies the impact this will have on CCS CAPEX/OPEX. This analysis helps to determine the optimum approach for any individual refinery site.

Traces of particulate mercury sulfide (HgS) in stabilized crude oils transform to elemental mercury below 400°C in refinery distillation units. The authors evaluated this transformation and measured reaction rates and activation energies in crude oil and Hg-spiked mineral oil, using glass vessels at atmospheric pressure and a microunit at 1,000 psig.

Refiners have used offline process models for decades. The next generation of solutions is anticipated to operate automatically, integrate with legacy systems and provide transparency site-wide.  

Prompt engineering is an emerging discipline at the intersection of AI and process engineering and will undoubtedly contribute to the hydrocarbon and green molecules processing industries. Parts 1 and 2 (October 2024) of this article explore and provide a glimpse of how this technique can help process engineers and operators to manage the power of advanced AI models to optimize processes, contribute to solve complex problems, and improve operational efficiency in refineries and petrochemical plants.  

The authors’ company has developed a novel approach with a digital algorithm to effectively estimate the current cyclone erosion and predict future erosion based on operating conditions. With this approach, refiners get an automatic way to better predict abrasion lining erosion for both reactors and regenerator cyclones daily from digital analytics, thus helping refiners quantify their monitoring.
