Attendees of the June 18-19 course in Estes Park have their registration fee waived for the Ultrasonic Meter Seminar.
Printed copy of comprehensive course notes are included.
Course Details
This course has two objectives. The first is to build a solid understanding of the hydrodynamic behavior. The second objective is to provide a comprehensive review and explanation of the current technology.
This course is designed for:
- Senior Technicians
- Engineers
This course has two objectives. The first is to build a solid understanding of the
hydrodynamic behavior. The second objective is to provide a comprehensive review and
examination of the current technology. This course is designed for senior technicians and
engineers.
The course material is divided into eight parts:
Part 1: What is Wet Gas Flow?
Discuss with class what they think wet gas is. Discuss different definitions of wet gas,
two-phase and multiphase flows. Give Definition of Common Wet Gas Terms. (This will
include the different Lockhart Martinelli parameters (with historical perspective), GVF,
LVF, liquid to gas mass and volume ratios, quality, void fraction, hold up, slip ratio,
“liquid loading”, gas and liquid densiometric Froude numbers and the modified Weber
number. Discuss conversion equations and graphs. Explain different institutions wet gas
flow definitions and how they relate to each other.
Part 2: What Does Wet Gas Flow Look Like?
Discussion on flow patterns of horizontal, vertical up and down and angled flows.
Discussion on flow pattern maps, theory uses and limitations. Taitel and Duckler’s semiempirical
flow pattern calculation method and the lessons it states (i.e. the affect different
parameters have on flow patterns). Horizontal flow wet gas videos.
Part 3: Wet Gas Flow Worked Examples
Many two-phase flows exist in industry. In this module the instructor and the class will
do worked examples on how to categorize a two-phase flow into wet gas, general two phase
and multiphase flows. Selected examples will be worked through by the instructor.
Each gives the class practice in doing the analysis themselves and each pre-selected
example has a specific lesson associated with it. (All six ASME SC19 Appendix 6
examples will be discussed). The class will be encouraged to bring specific field data
applications to work through with the instructor.
Part 4: Single Phase Non-DP Meters Wet Gas Flow Performance
Many wet gas flow applications have single phase gas meters installed. This is due to
either ignorance of the fact that the expected gas flow will wet gas flow at the design
stage or simply due to economic necessity. This module discusses the publicly released
information on how non-differential pressure meters perform with wet gas flows. Meters
discussed include the vortex meter, the turbine meter, the ultrasonic meter and the
Coriolis meter.
Part 5: Single Phase DP Meters Wet Gas Flow Performance
Single Phase DP meters are the most commonly used wet gas flow meter. These meters
are used a stand alone devices, or as components of more complex wet gas and
multiphase meters. This module discusses the known performance of this generic meter
type with wet gas with a historical perspective.
• Orifice meter: Murdock, Chisholm, Smith and Leang and Lin equations, other
published work.
• Venturi meter: de Leeuw and Steven equations and other published work.
• Cone meter: Steven equations and other published work.
• Other DP meters with wet gas, including eccentric orifice plate meter, venturi
nozzle and wedge meters.
• Generic theories of DP meter wet gas performance.
Part 6: Accessories for Single Phase DP Meters with Correction Factors
Test separators, tracer dilution technology, sampling and PVT. This module includes
worked examples where DP meter wet gas correlations are applied with use of liquid
flow rate information from test separator or tracer dilution technologies.
Part 7: Wet Gas Metering Generic Concepts
Many wet gas and multiphase meter technologies are patented and their details held in
commercial confidence. However, there are publicly known generic wet gas metering
concepts and most patented devices operate on these generic principles. In this module
these generic wet gas metering principles are discussed to give the class a grounding in
the main concepts used by the main commercial meters. Also included is discussion of
downstream pressure taps on generic DP meters, multiple gas meters in series, and brief
over views of phase fraction devices and partial separation technologies.
Part 8: Practical Wet Gas Metering Problems
Discussion on common field problems. Separator efficiency issues, saturation of DP
transmitters (with worked example) the dangers of extrapolating any wet gas correlation,
slugging damage, meter flooding, meter location issues, flow mixer and flow conditioner
problems, blockage due to hydrate (show CEESI videos), scale, salts, and thermodynamic
phase change issues.
