Refinery byproducts in dust suppression and the prevention of rock adhesion and freezing at mines

Resumo

The effectiveness of highly aromatic distillates and the heavy petroleum fraction from a Russian oil refinery in dust suppression and the prevention of the adhesion and freezing of powdery rock at mines is assessed. In order to ensure highly effective protective agents, a detailed study is made of how the hydrocarbon composition of light and heavy gas-oils in thermodestructive processes (catalytic cracking and delayed coking) affects the pour point depression by the heavy petroleum residue.
