In this mini-review, we examine the current state of several widely used process modeling tools, their features, and the adaptability to modeling state-of-the-art desalination process systems. We also discuss thermodynamic models of electrolyte solutions and their ability to accurately predict the thermodynamic properties of aqueous multielectrolyte solutions.

Even if pioneering works of the photocatalytic reaction between alcohols and water examined the outcome of the oxidation branch of the reaction, the use of these reagents passed through a period in which reporting only hydrogen evolution became common practice, assuming total oxidation and taking the consumption of the organic as a <em>sacrifice</em> for hydrogen production. However, in more recent years, the oxidation outcome of the reaction has regained attention, mainly because of the interest in coupling photocatalysis with biomass utilization. Thus, the <em>valorization</em> of biomass-derived alcohol hole scavengers has become an interesting topic in photocatalysis research. Here, we highlight some recent works on this topic, selecting those that have received more attention in the last 2–5 years: polyol (glycerol, glucose) valorization, transformations of furfuryl alcohol and 5-hydroxymethyl furfural, and C-C coupling reactions starting from alcohols.

However, the associated marine environments, characterized by instability and motions, such as tilting, rolling, and heaving, disrupt fluid dynamics, mass transfer, and reaction performance. This contribution examines recent advances in modeling fluid dynamics in (random/structured) packed columns and trickle beds under simulated marine conditions and highlights the role of dynamic gravity in these marinized multiphase packed bed applications.
