And the illustrations, maps, diagrams and photos peppered throughout make for a truly immersive read, even if you're just dipping in to settle a simmering argument about sparging.
Nitrogen sparging creates a significantly higher amount of surface contact between the gas and the product, which in turn creates a much larger opportunity for undesired oxidation to occur.
However, a system that utilizes nitrogen sparging (and then subsequently tank blanketing once the nitrogen reaches the vapor space) may have negative impact on the products involved.
