BENCHMARKS DE EFICIêNCIA NO PROCESSAMENTO DE PETRóLEO COM PRODUTOS QUíMICOS

This study aims to identify the best manufacturing plants by the criterion of efficiency in the useof chemicals to separate oil, water and gas in a primary processing plant oil. Thus, we evaluated theefficiency of thirty stationary production units operated by a concessionaire of oil in the Campos Basin, in2009. The efficiency was measured with the methodology of Data Envelopment Analysis (DEA) through itsclassical model DEA-CCR, with the help of software called SIAD. The results were identified by analysisunits which are references for use efficiency desemulsificantes for the treatment of crude oil.
