Process scale-up is the effort to take a chemical process that works at a smaller scale and design a version that will work similarly well at a larger scale. Oftentimes, the smaller process is in a laboratory and exhibits excellent product yields in a reactor measuring less than one inch in diameter; meanwhile, the larger […]
In this article I write about process technologies for preparation of slurries, AKA “solids in suspension,” and the considerations that must be made in equipment design. Mainly this includes powder wettability, but I will also briefly outline reactions, rheology, and several other considerations. For slurry preparation, our initial state is one in which the dry […]
One of the most frustrating situations to endure is the slow cooldown of a reactor (or series of reactors) when shutting down a hydrocracker, hydrotreater, or renewable feed unit. It often seems that the entire refinery is watching the reactor cool, especially as reactor temperatures drop below 200⁰F. This blog article will cover ways to […]
