EOS-CG-2021: A Mixture Model for the Calculation of Thermodynamic Properties of CCS Mixtures

November 16, 2023
Author(s)
Tobias Neumann, Stefan Herrig, Ian Bell, Robin Beckmuller, Eric W. Lemmon, Monika Thol, Roland Span
Thermodynamic properties for CCS-relevant mixtures can be calculated with the fundamental equation of state presented in this work over wide ranges of pressure, temperature, and composition for gas, liquid, and supercritical states, as well as phase

Non-nulling Protocols for Fast, Accurate, 3-D Velocity Measurements in Stacks

July 28, 2023
Author(s)
Iosif Isaakovich Shinder, Aaron Johnson, James Filla, Vladimir B. Khromchenko, Michael R. Moldover, Joey Boyd, John D. Wright, John R. Stoup
We present protocols for making fast, accurate, 3-D velocity measurements in the stacks of coal-fired power plants. The measurements are traceable to internationally-recognized standards; therefore, they provide a rigorous basis for measuring and/or

EFFECT OF FLUID PROPERTIES ON CONTACT ANGLES IN THE EAGLE FORD SHALE MEASURED WITH SPONTANEOUS IMBIBITION

November 19, 2021
Author(s)
Joanna McFarlane, Victoria H. DiStefano, Philip R. Bingham, Hassina Z. Bilheux, Michael C. Cheshire, Richard E. Hale, Daniel Hussey, David Jacobson, Lindsay M. Kolbus, Jacob LaManna, Edmund Perfect, Mark Rivers, Louis J. Santodonato, Lawrence M. Anovitz
Models of fluid flow are used to improve the efficiency of oil and gas extraction and to estimate the storage and leakage of carbon dioxide in geologic reservoirs. Therefore, a quantitative understanding of key parameters of rock-fluid interactions, such

A portable triaxial cell for beamline imaging of rocks under triaxial state of stress

April 21, 2021
Author(s)
Amer Syed, Yukie Tanino, Jacob LaManna, David L. Jacobson, Daniel S. Hussey, Eli Baltic, Genoveva Burca
With recent developments in direct imaging techniques using x-ray and neutron imaging, there is an increasing need for an efficient design of a test setup to study mechanical and/or the transport behaviour of porous rocks. Bespoke design from commercial

Improved characterization of methane emissions from the U.S. oil and gas supply chain

June 21, 2018
Author(s)
Ramon A. Alvarez, Daniel Zavala-Araiza, David R. Lyon, David T. Allen, Zachary R. Barkley, Adam R. Brandt, Kenneth J. Davis, Scott C. Herndon, Daniel J. Jacob, Anna Karion, Eric A. Kort, Brian K. Lamb, Thomas Lauvaux, Joannes D. Maasakkers, Anthony J. Marchese, Mark Omara, Stephen W. Pacala, Jeff Peischl, Allen L. Robinson, Paul B. Shepson, Colm Sweeney, Amy Townsend-Small, Steven C. Wofsy, Daniel Zimmerle, Steven P. Hamburg
The contribution of the U.S. oil and natural gas supply chain to global methane emissions - an important factor in climate warming - was estimated using ground-based measurements and validated with region-wide aircraft measurements in areas accounting for

Progress Towards Accurate Monitoring of Flue Gas Emissions

May 16, 2018
Author(s)
Aaron Johnson, Iosif Isaakovich Shinder, Michael R. Moldover, Joey Boyd, James Filla
The amounts of CO2 and other pollutants emitted by a coal-fired power plant are measured using a continuous emissions monitoring system (CEMS) permanently installed in the exhaust smokestack. The pollutant flux is the product of the pollutant's

Laser-Driven Calorimetry of Single-Component Liquid Hydrocarbons

June 12, 2017
Author(s)
Cary Presser, Ashot Nazarian
A novel laser-heating technique, referred to as the laser-driven thermal reactor (LDTR), was used to determine sample thermal behavior, specific heat release rate, and total specific heat release of three volatile single-component liquid hydrocarbons, i.e

Classification of petroleum Standard Reference Materials and other fuels by chemometric analysis of gas chromatography-mass spectrometry data

February 23, 2017
Author(s)
Werickson Fortunato de Carvalho Rocha, Michele M. Schantz, David Sheen, Katrice Lippa, Pamela M. Chu
As feedstocks transition from conventional oil to increasing amounts of unconventional petroleum sources and biomass, it will be necessary to determine whether a particular fuel or fuel blend is suitable for use in engines. Certifying a fuel as safe for

Reference Correlations of the Thermal Conductivity of Ethylene and Propylene

August 9, 2016
Author(s)
A. Koutian, Marc J. Assael, Marcia L. Huber, Richard A. Perkins
New, wide-range reference equations for the thermal conductivity of ethylene and propylene as a function of temperature and density are presented. The equations are based in part upon a body of experimental data that has been critically assessed for
