Sulfuric Acid Treatment: DDPS

Sulfuric Acid Treatment: DDPS

Multi-stage evaporators save energy when concentrating sulfuric acid from 20 wt% up to e.g. 70 wt%. Concentrating sulfuric acid from 20 to 70wt% means to evaporate an enormous amount of water out of the sulfuric acid. Single or multi stage natural circulation evaporators are used to minimize the required amount of heating steam.

Does sulphuric acid evaporate over time? : chemistry

Does sulphuric acid evaporate over time? : chemistry

Sulphuric acid has a very low vapour pressure, so it barely evaporates at all. Now, the MARQUIS reagent has another component, which is formaldehyde. Formaldehyde does easily evaporate and can reversibly form a white polymer when it condenses. This polymer, paraformaldehyde, can be just as dangerous as the formaldehyde itself, so treat it .
