Scada And Telemetry In Natural Gas Operations

Author: Russel W. TreatDownload File

SCADA systems are combinations of field devices, communications infrastructure, computer hardware and software integrated into a system that provides for safe, reliable, and effective operation of remote facilities. Producers, gatherers, midstream operators and pipelines use SCADA system for operations. In addition, SCADA gathers data used by advanced applications such as measurement accounting. SCADA is key […]

Phmsa’s Rule Impact On Gas Measurement (control Room Management)

Author: Russel W.TreatDownload File

This paper summarizes a SCADA implementer’s perspective regarding the intent of the Pipeline Hazardous Materials Safety Administration’s (PHMSA) Control Room Management (CRM) rule. In addition, this paper provides a fresh approach to CRM, describing why companies should use the CRM process to go beyond compliance requirements and implement operating best practices that would significantly enhance […]

Periodic Inspection Of Regulators And Relief Valves

Author: James M. DoyleDownload File

Inspections and tests on regulators and relief valves is a Department of Transportation Compliance rule. The sections within the DOT manual stating the rule include 192.351 through 192.359, 192.751, 192.479, 192.481, 192.739, and 192.741. Keep in mind; these rules are the minimum required tests. Your Company or Regulatory Agency may be more stringent and require […]

Field Testing Gas Meters By Transfer Proving

Author: Larry K. WunderlichDownload File

Transfer proving was initially developed to provide an easier and more accurate field meter proving method. Because of the capacity capabilities of transfer provers (2000 CFH to 80,000 CFH) transfer provers are utilized in meter shops where bell prover capacity is limited and allow for shop testing of the larger capacity meters. TRANSFER TESTING SYSTEM […]

Compairing Plug & Seat Regulators & Control Valves

Author: Rick SchneiderDownload File

In today’s charging world of technology there have been may changes in controls that now allow to truly compare a plug and seat regulator to a control valve for high-pressure natural gas installations such as: power plants, city gate stations, large industrial customers, compressor stations, and storage fields. The features, benefits, capabilities, and differences of […]

Techniques For Composite Gas Sampling

Author: David J. FishDownload File

The need to be able to take a representative sample of a hydrocarbon product is necessary to ensure proper accounting for transactions and efficient product processing. The various sampling methods that are available and the options and limitations of these methods are investigated; the most appropriate equipment to use; the reasons for its use and […]

Sampling Challenges Associated With Unconventional Gas Sources

Author: Mark FirminDownload File

Advances in exploration, drilling and production technologies make it feasible to extract natural gas from sources that in the past have been regarded as unconventional and so, such sources are becoming a larger percentage of the gas supply. The feasibility of producing gas from a source is the primary factor in determining whether that source […]

Use Of Equation Of State (eos) Software

Author: Adam G. Hawley Darin L. GeorgeDownload File

Determination of fluid properties and phase conditions of hydrocarbon mixtures is critical for accurate hydrocarbon measurement, representative sampling, and overall pipeline operation. Fluid properties such as compressibility and density are critical for flow measurement, and determination of the hydrocarbon due point is important to verify that heavier hydrocarbons will not condense out of a gas […]
