The Research of Heating Furnace with Heavy Oil Desander ...

Abstract Based on the domestic and foreign oil field used heating furance, the pipes and instruments are worn and jammed by the sand in the heavy oil. The incrustation are formed on pipes’ inner surface which can cause cross-sectional area to be reduced, the thermal resistance rate and fuel costs to be increased. Even the probability of pipeline leak, maintenance or human resource spending ...

Hydrocyclone Filter Calculation Parameters. The ratio of the lower d н and upper d в drain pipe diameters is one of the most important parameters in the hydrocyclone d в /d н ratio defines the condensed and clarified product ratio at the port outlet. Numerically, this relation can be represented by an approximate formula: Q н /Q в . Know more
