(1) Suitable heating for heavy fuel oil "C grade" and intense agitation are effective for the mixing process.(2) At the mixing ratio of 3, (the ratio of the weight of heavy fuel oil "C grade" to the weight of liquefied butane) dynamic viscosity of about 20 [cst] which is required...
Residual oils, high viscosity and large sulfur content petroleum products from the refining process of crude oil, are receiving increasing interest in pre-combustion carbon capture applications. Gasification is a promising technology to convert such complicated hydrocarbons into syngas. Pyrolysis and combust...
In redn. of the viscosity of heavy oil residues, the residue is treated at high temp., for a time equiv. to 250-2500 equiv. reaction time (FRT) secs. at 427 deg.C, with a H donor solvent comprising a fuel oil from steam-cracking, with a content of aromatic cpds. above 90%, ...
1. The viscosity of these heavy crude oils continually decreases as the temperature increases. It shows that the density and viscosity of crude oil A are bigger than crude oil B. The rheological measurement shows the same results between tap-water-oil and mineral-water-oil dispersed mixtures. ...

We mainly researched the influence of oil viscosity on stability of foamy oil in the process of heavy oil solution gas drive. Through sand-pack experiment, we researched foam quality and half-life period of foamy oil for different oil viscosity under atmosphere pressure and temperature of 25 °...
Though the inherent properties of heavy oil such as high density and viscosity, high concentration of heteroatoms, presence of compounds with high molecular weight e.g. resins and asphaltenes, presence of metals such as nickel and vanadium, low hydrogen content and low API gravity remains a ...
