Gas Odorants: Safe Handling, Health and Environment
Dr Daniel Arrieta, Chevron-Phillips Chemical Company
This presentation covers the occupational hazards and environmental impacts of odorants, the regulatory requirements, and recommendations for safe handling and personal protection equipment (PPE).
Odorant Transfer Systems and Safe Efficient Deliveries
Juraj Strmen, MRR
A detailed discussion of odorant transfer systems (including closed loop, flare, and venting) for product transfers from stationary and portable tanks. The discussion will focus on operations safety, closed loop designs, and system integrity.
This presentation covers maintenance of gas chromatographs, including the sample handling system, and the gas chromatograph analyzer. In addition, it also covers routine diagnostics and system overhaul.
Discuss pipeline conditioning, pickling, and odor fade in new construction, conversions, and in the maintenance of existing odorized facilities.
Gas Quality/Odorization Papers
Best Practices/General Interest
Hazardous Area Classification
Larry Matora, SoCal Gas
This presentation reviews AGA and API standards, utilized in determining the hazardous location classification for electrical wiring, along with discussion of typical hazardous location classifications encountered in the gas industry.
Peter Cartnell and Selwyn Pandian, Galvanic Applied Sciences
Do you know what to expect when servicing online process analyzers? Other than routine maintenance, there are infinite surprises that can occur leaving you scratching your head. In this session, we will be sharing some war stories from the field. Led by an experienced field service engineer, they will share insights for how to approach problem solving.
For those new to measurement or needing a refresher, an introduction to the basic gas laws including Boyle's Law, Charles' Law, Ideal Gas Law, and supercompressibility; and how they are used in gas measurement.
Discussion of the theory of operation of ultrasonic meters including velocity of sound determination; effects of gas composition, gas velocity, flow conditioning, and flow profiles; accuracy and uncertainty; and flow calibration.
This class will focus on the basic theory, operating principles, performance characteristics and installation requirements used in turbine meter applications. A discussion of fundamental turbine meter terminology is also included.
A discussion of the specific considerations the engineer should consider when designing ultrasonic meter installations such as noise abatement, header design, meter maintenance and gas flow conditioning.
The lecture-type workshop will discuss the importance of accurate gas meter proving and testing. The discussion will introduce common gas meter testing terminology and definitions, describe the three most common types of distribution gas meter test equipment, explain proper prover calibration and certification techniques, and list common direct and indirect concerns that may lead to errant gas meter test results.
In this workshop we will discuss elements that make up combined accuracy: over/under calculation of EVC accuracy. Technician error/mis-programming, transducer error, RTD error, meter error and meter degradation. How to calculate “as found” and “as left” combined accuracy. Billing and LUAF impact.
Discuss meter sampling program specifications and results. Sub-topics to include sample criteria, acceptable accuracy for meter retention, regulatory requirements, meter family replacement, considerations and trends; and related economics factors.
This presentation describes a new field verification process that represents a compromise between diagnostic monitoring and a laboratory re-calibration. The presentation begins with a description of AGA6, the meter package, connecting piping, and instrumentation. The discussion continues with a case study that highlights the verification process and results.
A New Approach to Optimal Flow Profiles and Noise Attenuation – Geoff Hager, Big Elk
This presentation describes a new ultrasonic meter tube design which improves the flow profile and reduces noise while maintaining an in-line piping arrangement. The discussion continues with recent lab data which highlights the flow profile and noise attenuation results of the new design.
Introduction to Gas Regulation
Robbie Swigert, Itron
The fundamentals of pressure regulation covering spring and pilot type regulators, sizing, operation, and troubleshooting.
Presentation of the advantages and disadvantages of flexible element regulators including a review of monitor and single cut/relief applications, principles of operation, sizing, installation/ maintenance, and best practices.
Presentation will offer a systematic approach to troubleshooting. Discussion will include common causes of delivery pressure problems at regulation facilities: overpressure, under-pressure, cyclic or unstable control; and solutions for those issues.
