Study of loose bulk cargo storage conditions and water transportation

When transporting such cargos as mineral fertilizers by water, they absorb moisture, which stimulates cargo self-heating and ultimately leads to dangerous temperature limits. When transporting ANP fertilizer in holds, its equilibrium moisture content can change significantly, which can lead to the c...

description	When transporting such cargos as mineral fertilizers by water, they absorb moisture, which stimulates cargo self-heating and ultimately leads to dangerous temperature limits. When transporting ANP fertilizer in holds, its equilibrium moisture content can change significantly, which can lead to the cargo damage.

There is no analytical description of moistening processes of porous bodies associated with these phenomena in the scientific literature. The optimal conditions for storage and transportation of bulk materials have been determined on the example of ANP fertilizer transported through the Novorossiysk seaport.
