This report presents technology background and test results on an improved Leak Detection and Control method for application in refineries and petrochemical plants. Smart Leak Detection and Repair (LDAR) focuses on locating and repairing the most significant...
This document describes procedures for predicting uncertainties in the detection of leaks in pipelines using computational methods based upon physical hydraulic state measurements. This class of pipeline leak detection methods is commonly called...
Mitigation of Gas Pipeline Integrity Problems presents the methodology to enable engineers, experienced or not, to alleviate pipeline integrity problems during operation. It explains the principal considerations and establishes a common approach in tackling technical challenges that...
This Report was prepared originally in 1967 by Technical Section E of the Gas Processors Association and revised in 1975. It is intended as a practical and convenient guide in detecting, locating, and measuring common corrosion problems in gas processing plants and related equipment. It was...
Water and wastewater infrastructure are a somewhat invisible, yet critical, part of modern life. Incredibly, many buried assets have been in service for 50-100 years and are still in good condition. Conversely, other systems fail well before their predicted design lives, causing property damage,...
SCOPE AND OBJECTIVES The project objectives were to: • identify different technologies available for leak detection and location for the selected type of pipelines, • identify vendors of each technology, • select vendors for testing, • conduct range-finding tests of the...
5.1 The measurement of mercaptans in natural gas is important, because mercaptans are often added as odorants to natural gas to provide a warning property. The odor provided by the mercaptan serves to warn consumers (for example, residential use) of natural gas leaks at levels that are well...
Preface Water main condition assessment currently ranks among the most important subjects to water utilities, and interest in this subject is rapidly growing. As the average age of their infrastructures increases, utilities are increasingly challenged to maintain levels of service while keeping...
General This part of the IEC 62443 series is a technical specification which defines the terminology, concepts and models for Industrial Automation and Control Systems (IACS) security. It establishes the basis for the remaining standards in the IEC 62443 series. To fully articulate the systems and...
4.1 The measurement of mercaptans in natural gas is important, because mercaptans are often added as odorants to natural gas to provide a warning property. The odor provided by the mercaptan serves to warn consumers (for example, residential use) of natural gas leaks at levels that are well...
1.4 SCOPE Three general types of software-based leak detection methods are addressed in this study: (1) mass balance, (2) mass balance with linefill correction, and (3) transient flow analysis. The leak detection potential of these methods will be discussed based on...
1.1 This test method covers a rapid and simple field determination of mercaptans in natural gas pipelines. Available detector tubes provide a total measuring range of 0.5 to 160 ppm by volume of mercaptans, although the majority of applications will be on the lower end of this range (that...
