METHOD OF TRANSPORTATION OF NON-NEWTONIAN PARAFFIN-CONTAINING HYDROCARBON FLUID VIA PIPE LINE

摘要

FIELD: pipe line transport of non-Newtonian paraffin-containing hydrocarbon fluids, namely, oil of one field or mixture of oils of several fields, as well as petroleum products and gas condensate through anisothermic pipe lines. SUBSTANCE: method includes delivery of depressing additive into preheated hydrocarbon fluid at the beginning of pipe line. First, delivery of depressing additive is continued within length of time required for filling the section of pipe line at laminar flow of fluid; then anti-turbulent additive is additionally delivered to beginning of pipe line. Transfer is effected in the presence of both additives. Amount of anti-turbulent additive shall be dictated by mass of fluid filling the section of pipe line with turbulent flow; amount of depressing additive shall be dictated by mass of fluid filling the entire pipe line. EFFECT: optimization of amount of additives being introduced; reduced hydraulic resistance at transfer of non-Newtonian paraffin-containing hydrocarbon fluid through anisothermic pipe line. 1 dwg
