METHOD FOR INTEGRATED ASSESSMENT OF ENERGY EFFICIENCY OF PROCESS PLANT FOR PUMPING LIQUID MEDIA DURING OPERATION THEREOF

摘要

FIELD: engines and pumps.;SUBSTANCE: method for integrated assessment of energy efficiency (EE) of the process plant (PP) for transfer of fluids at given process during its operation includes initial registration of nominal parameters of each PP component, simultaneous measurement of instantaneous actual values of electrical and technological parameters of PP, calculation of efficiency and specific power consumption for each component of PP, determination of actual and reference values of each parameter which characterises PP energy efficiency. Then actual and reference specific consumption of electric power (SEC) of installation are calculated. If SEC differs from reference values for more than allowable value, actual and reference values of said parameters are compared, characterizing PP efficiency, select and implement measures aiming at high level of SEC of PP component parts, which have invalid deviation from SEC level. Then at same algorithm by estimating EE of PP component parts until obtaining of maximum possible value of EE of unit as whole. Components of PP are control station, motor and pump.;EFFECT: invention is aimed at saving of energy consumption due to high reliability of integrated assessment of energy efficiency of PP and each part, as well as due to timely measures to increase its efficiency as whole.;2 cl, 1 dwg, 1 ex
