METHOD FOR CONTROLLING OILS COMPOUNDING PROCESS WITH SEVERAL QUALITY PARAMETERS AND SYSTEM FOR REALIZATION OF SAID METHOD Russian patent published in 2006 - IPC G05D11/02 F17D3/00 

FIELD: engineering of means for automation of oil transportation process along different pipelines with different quality of oil and joining oil flows with control over quality parameters of oil mixture.

SUBSTANCE: in the method for controlling oil compounding process, flow values for transported oil flows are measured and also flow of mixed oil flow, content in transported flows and in mixed oil flow of sulfur and/or water is determined, relations of aforementioned contents in each of transported flows are determined and in mixed flow and relations of losses of each of transported flows and mixed flow and these relations are compared to given values, if all relations of flows correspond to given values and in case of deviation of relation of aforementioned contents for at least one transported flow oil flow is adjusted for appropriate flow, process for determining sulfur and/or water content in each of transported flows is performed by measuring density of oil in appropriate flow with consideration of correlation dependency between density and content of aperture component. System for controlling oil compounding process having , mounted in each oil pipe for transporting oil, flow meter, oil density meter and means for adjusting oil flow, mounted in oil pipe for mixed flow, oil flow meter, sulfur and/or water content meter, and also calculating device for coefficients of relation of oil flows in each transported flow and in mixed flow and/or device for calculating coefficients of relation of water contents in oil for each transported flow and in mixed flow, inputs of first of aforementioned calculating devices are connected to flow meters, and outputs of each one of aforementioned calculating devices are connected to appropriate inputs of comparison block, outputs of which are connected to means for adjusting oil flow, is provided with device for calculating sulfur content and/or device for calculating water content in oil, made with possible calculating of content of appropriate component with consideration of correlation dependency between oil density and content of aforementioned component, inputs of each of calculating devices are connected to oil density meters of transported flows, and outputs are connected to appropriate inputs of appropriate device for calculating relation coefficients.

EFFECT: increased efficiency.
