METHOD FOR DETERMINATION OF PIPE-LINE DIAMETER Russian patent published in 1999 - IPC

Abstract RU 2142597 C1

FIELD: pipe-line transport, applicable mainly in conveyance of petroleum with a high gas factor for obtaining a stable emulsion structure in a pipe-line, type "liquid in gas". SUBSTANCE: the speed of the gas phase is determined according to the Weber criterion equal to or exceeding 11.5 with due account made for its density, drop diameter and surface tension on the boundary of phase separation, the required pipe-line diameter is determined from the found speed from expression , where Q'- volume flow rate of liquid; Q" - volume flow rate of gas reduced to Tmean and Pmean; the found value of pipe-line diameter is rounded off down at its selection from the GOST tables. EFFECT: reduced powder consumption, prevented damage of pipes, clogging and water hammer.
