Upstream Gas Measurement
Author(s): J. Bowen
Abstract/Introduction:
2 Name Confidential Date Center line content NATURAL GAS PRODUCTION ? Produced natural gas comes from natural or stimulated reservoirs. ? Both reservoir types often co - produce liquids with the gas ? Well - pad separation is typical, but gas flowing from it is usually at or near, either or both of, water or hydrocarbon dew points. ? Additionally, well site separation may fail or flood , leading to liquid carry - over into the produced gas stream, and 2 phase flow. ? Gas near its dew point is also subject to retrograde condensation of liquids. ? Wet Gas: Taken together, these factors means the gas at the well head metering point is usually saturated , may have mist flow , will periodically/randomly be contaminated with free liquid , and for which residue or standing fluid might collect in the measuring section

Usm GT400Customer Presentationv3 21Mar14 7/16/14 1 A Six (6) Path Ultrasonic Gas Flowmeter With 3D-Fidelity
Abstract/Introduction:
evere disturbance testing (HMP) did not pass within the OMIL limits AND without a flow conditioner. Class 1 all other testing. NO Flow Conditioner. The recorded datasets have shown that there was a difference to be distinguished, with on-line real-time diagnostics, between the high level disturbance at 10D inlet length compared to the same disturbance at a 20D inlet. The 10D datasets that were recorded were outwith the OIML Class 1 limits there were deviations especially at high flow rates that were more than 0.5% however the general behavior deviated significantly from the baseline. After 20D the effect of the disturbance is reduced and only one of the three datasets had two values at low flow rates that were outwith the Class 1 limit by less than 0.05%

Diagnostic Analysis Of Velocity Profile Using An 8 - Path Gas Ultrasonic Meter
Author(s): Dr Gregor Brown
Abstract/Introduction:
he original promise of gas USMs was that they would deliver the benefits of being non - intrusive and low maintenance However, with experience, use of flow conditioning has become very common There is an underlying assumption in the early multipath designs that each path supplies a measure of axial velocity

Nists Smokestack Simulator Design And Research Program
Author(s): Aaron Johnson
Abstract/Introduction:
Government regulations require that hazardous pollutants emitted from smokestacks be continuously measured The amount a greenhouse gas (GHG) or other pollutant emitted from a smokestack equals the bulk mass flow multiplied by the concentration Smokestacks are instrumented with Continuous Emissions Monitoring Systems (CEMS) to measure both flow and concentration - CEMS flow meter - CEMS instrumentation to measure concentration Shortcomings of existing smokestack flow measurement methods - CEMS flow measurement methods and technologies have not been quantified against documented flow standards ( i . e . , not traceable) - CO 2 emissions measurement estimated to be between 10 % and 20 % To assess GHG mitigation efforts requires accurate emissions measurements If future regulations are established for GHGs than reduced uncertainty measurements will likely be necessary

Lact Design From A Design And Fabrication Prospective
Author(s): Stormy Phillips
Abstract/Introduction:
What is a LACT system? A LACT unit is a group of equipment designed specifically for the unattended custody transfer between a lease and the method of transportation to remove the liquids from the lease. In doing this the unit must be able to provide volume and quality of the liquids, provide for fail - safe and tamper proof operation, and meet the requirements of accuracy deemed necessary by both parties

Ngl Measurement Direct & Inferred Mass
Author(s): Ngl Measurement Direct & Inferred Mass Marsha Yon
Abstract/Introduction:
Mass measurement techniques are used on compressible fluids with varying composition where the volume is affected by intermolecular adhesion and solution mixing. Light hydrocarbons have poorly defined properties of thermal expansion and compressibility and the fluid density changes a large amount with small changes in temperature and pressure. - Polymer - grade ethylene - Ethane - Liquefied petroleum gas (LPG) - Ethane/propane (E/P) mixtures - Natural gas liquids (NGL) such as raw make streams - Y grade and condensates

The Coriolis Effect
Author(s): Rick Heuer
Abstract/Introduction:
Coriolis meters benefitted from all the work done on gas ultrasonic meters (USM ) ? When natural gas USMs were starting out, some models did not have frequency outputs . ? The meter was more of an Engineering tool rather than a measurement device . ? After a frequency output was added, it became usable as per AGA - 7 requirements. Diagnostics are now used to examine the flowing gas and metering abnormalities . ? Not just diagnostics, but process applications, built - in totalizers, history, alarms and events
