Chemical Process Safety - mt

Chemical process safety is concerned with ensuring that the energy released by the reaction can be safely removed from the reactor without the risk of thermal runaway or explosion. Simple at the laboratory scale, it becomes progressively more difficult throughout scale-up, due to the changing ratio of heat removal capacity to reactor volume.

Corrosion | chemical process | Britannica

Corrosion, wearing away due to chemical reactions, mainly oxidation (see oxidation-reduction, oxide). It occurs whenever a gas or liquid chemically attacks an exposed surface, often a metal, and is accelerated by warm temperatures and by acids and salts. Normally, corrosion products (e.g., rust, patina) stay on the surface and protect it.
