Description
Summary:Made available in DSpace on 2015-03-03T13:59:44Z (GMT). No. of bitstreams: 1 GabriellJMA_DISSERT.pdf: 1371633 bytes, checksum: 92e16086f0ca63a45223381e044469ad (MD5) Previous issue date: 2012-03-05 === In February 2011, the National Agency of Petroleum, Natural Gas and Biofuels (ANP) has published a new Technical Rules for Handling Land Pipeline Petroleum and Natural Gas Derivatives (RTDT). Among other things, the RTDT made compulsory the use of monitoring systems and leak detection in all onshore pipelines in the country. This document provides a study on the method for detection of transient pressure. The study was conducted on a industrial duct 16" diameter and 9.8 km long. The pipeline is fully pressurized and carries a multiphase mixture of crude oil, water and natural gas. For the study, was built an infrastructure for data acquisition and validation of detection algorithms. The system was designed with SCADA architecture. Piezoresistive sensors were installed at the ends of the duct and Digital Signal Processors (DSPs) were used for sampling, storage and processing of data. The study was based on simulations of leaks through valves and search for patterns that characterize the occurrence of such phenomena === Em fevereiro de 2011, a Ag?ncia Nacional de Petr?leo, G?s Natural e Biocombust?veis (ANP) publicou o novo Regulamento Tecnico de Dutos Terrestres para Movimenta??o de Petr?leo, Derivados e Gas Natural (RTDT). Entre outros aspectos, o RTDT tornou obrigat?rio o emprego de sistemas de monitoramento e detec??o de vazamentos em todos os dutos terrestres do pa?s. Este documento traz um estudo sobre o m?todo de detec??o por transiente de press?o. O estudo foi realizado num duto industrial de 16" de di?metro e 9,8 Km de extens?o. O duto e totalmente pressurizado e transporta uma mistura multif?sica de ?leo bruto, ?gua e g?s natural. Para a realiza??o do estudo, foi constru?da uma infraestrutura de aquisi??o de dados e valida??o de algoritmos de detec??o. O sistema foi concebido com arquitetura SCADA. Sensores piezoresistivos foram instalados nas extremidades do duto e Processadores Digitais de Sinais (DSPs) foram usados para a amostragem, armazenamento e processamento dos dados. O estudo se baseou na realiza??o de simula??es de vazamentos por meio de valvulas e busca por padr?es que caracterizassem a ocorr?ncia de tais fen?menos
