Yakela Crude

1 Crude property

Tahe heavy crude blending appears thin black, flow property is good at room temperature, the normal property is shown in table 1. From which the properties are: low density（783.2kg/m3）, low Conradson carbon residue（0.22m%），It is very good light crude.

From the narrow distillation yield, 350℃fraction is very good residuum FCC feed.
