SYSTEM FOR COMPOUNDING SOUR CRUDE OIL IN MULTIPLE DIRECTIONS OF PUMPING MIXED FLOWS

摘要

FIELD: machine building.;SUBSTANCE: invention relates to automation and can be used in pipeline transportation during oil intake from one pipeline or from several branches in several common lines by which mixture of oils is transported to consumer. Distinctive feature of invention is introduction of into the system structure of following units for control over oil compounding: coefficients calculator of oil flow rate ratio in each transported flow and in mixed flow, calculator for oil density ratios in each transported flow and in mixed flow, real time calculator for required compounding efficiency value in direction of transfer, required for plan execution monitoring. Inputs of said calculators are connected to flow and density sensors, and outputs of calculators are connected to inputs of control unit.;EFFECT: technical result is provision in automatic mode of different at certain quality indicators oil grades compounding with simultaneous or sequential transfer of mixed flow via several main pipelines.;4 cl, 2 dwg
