Análisis técnico – económico para el reemplazo de medidores de desplazamiento positivo por medidores másicos tipo coriolis en las unidades de transferencia de custodia de hidrocarburos (LACT) en el campo Singue

Abstract

This technical - economic study aims to perform the analysis for replacing positive displacement meters by Coriolis mass meters in a Lease Automatic Custody Transfer Unit (LACT). Chapter one describes the characteristics at field Singue. Chapter two describes the theoretical foundation for the understanding of both static and dynamic measurement. These two types of volumetric measurement are in the Manual of Petroleum Measurement Standards (MPMS). The third chapter studies the necessary for the preparation of the worksheet that allows the development of capacity tables for calibrating atmospheric tanks both fixed roof and floating roof. Chapter four describes the principles of operation of the meters analyzed in this study, studying all the considerations and requirements for the installation, operation and maintenance. Also, the information of flow meter provers for meter calibration (Meter Factor). The first section of Chapter five presents technical analysis based on the production requirements at field Singue, the advantages and disadvantages of each meter and specifications compiled from different suppliers. The study is based in comparative tables that establish what is the best alternative will be used. The second section presents the economic analysis of the project based on VAN and TIR economic indicators.
