Younglove and Neil A. Olien Chemical Engineering Science Division National Engineering Laboratory- National Bureau of Standards Boulder, Colorado 80303 Custody transfer tables are presented for oxygen, argon, nitrogen, helium, and hydrogen. The tables are based on standard reference data previously compiled by the National Bureau of Standards. Two sets of tables are provided for each fluid. Tables in engineering units cover the range -40 to 130°F with pressures from 100 to 10,000 psig. Tables in SI units (density versus pressure and temperature) cover the range 200 to 370 K with pressures from 0.5 to 70 MPa. The tables in engineering units are designed to provide a means of determining the volume of gas at standard conditions contained in a tank given the volume of the tank and the pressure and temperature of the gas within the tank. The publication also includes four examples of use of the tables in calculating tank quantities. Key words: argon; custody transfer; gas density; gas volume; helium; hydrogen; nitrogen; oxygen. 1 . Introduction Industrial gases are important commodities in the Chemical Processes Industry as well as in other segments of the U. S. economy. Custody transfer of these gases usually takes place at high pressure and ambient temperatures with a wide variation in the latter depending on location and season. Normal custody transfer is based upon the volume the gas would occupy at standard conditions (standard conditions are defined here as 29M.26 K (70.0<'F)1 and 0.101325 MPa (14.696 Ib/in^))"!. The tables presented are designed to provide a relatively easy means of determining the volume of gas at standard conditions contained in a tank given the volume of the tank and the pressure and temperature of the gas within the tank. Tables are provided for each of the five fluids: oxygen, argon, nitrogen, helium, and hydrogen. Also included for each of the five ^Departing from usual NBS practice, the International System of Units (SI) were not used exclusively in this publication in order to meet the needs of the sponsoring agency, the Compressed Gas Association. 1 fluids are tables in SI units (the International System of Units) of density as a function of pressure and temperature. The National Bureau of Standards has a long history of accurate determina- tion of the therraophysical properties of fluids and in the critical evaluation and correlation of the properties of a wide variety of pure fluids and mixtures. Much of the latter work was performed under the sponsorship of other government agencies. The work from which these tables are derived is a good example. The helium and hydrogen tables were prepared from a computer program called "Fluids Pack" (McCarty [1]) at NBS, Chemical Engineering Science Division for the Johnson Space Center of the National Aeronautics and Space Administration. The tables for the other three fluids were derived from tables of thermophysical properties and accompanying computer programs prepared under the sponsorship of the NBS-Office of Standard Reference Data (Younglove [2,3]). The computer codes are available from the Office of Standard Reference Data [^] for those desiring copies

  • Prebiological Evolution and the Metabolic Origins of Life
    Prebiological Evolution and the Andrew J. Pratt* Metabolic Origins of Life University of Canterbury Keywords Abiogenesis, origin of life, metabolism, hydrothermal, iron Abstract The chemoton model of cells posits three subsystems: metabolism, compartmentalization, and information. A specific model for the prebiological evolution of a reproducing system with rudimentary versions of these three interdependent subsystems is presented. This is based on the initial emergence and reproduction of autocatalytic networks in hydrothermal microcompartments containing iron sulfide. The driving force for life was catalysis of the dissipation of the intrinsic redox gradient of the planet. The codependence of life on iron and phosphate provides chemical constraints on the ordering of prebiological evolution. The initial protometabolism was based on positive feedback loops associated with in situ carbon fixation in which the initial protometabolites modified the catalytic capacity and mobility of metal-based catalysts, especially iron-sulfur centers. A number of selection mechanisms, including catalytic efficiency and specificity, hydrolytic stability, and selective solubilization, are proposed as key determinants for autocatalytic reproduction exploited in protometabolic evolution. This evolutionary process led from autocatalytic networks within preexisting compartments to discrete, reproducing, mobile vesicular protocells with the capacity to use soluble sugar phosphates and hence the opportunity to develop nucleic acids. Fidelity of information transfer in the reproduction of these increasingly complex autocatalytic networks is a key selection pressure in prebiological evolution that eventually leads to the selection of nucleic acids as a digital information subsystem and hence the emergence of fully functional chemotons capable of Darwinian evolution. 1 Introduction: Chemoton Subsystems and Evolutionary Pathways Living cells are autocatalytic entities that harness redox energy via the selective catalysis of biochemical transformations.

  • And Abiogenesis
    Historical Development of the Distinction between Bio- and Abiogenesis. Robert B. Sheldon NASA/MSFC/NSSTC, 320 Sparkman Dr, Huntsville, AL, USA ABSTRACT Early greek philosophers laid the philosophical foundations of the distinction between bio and abiogenesis, when they debated organic and non-organic explanations for natural phenomena. Plato and Aristotle gave organic, or purpose-driven explanations for physical phenomena, whereas the materialist school of Democritus and Epicurus gave non-organic, or materialist explanations. These competing schools have alternated in popularity through history, with the present era dominated by epicurean schools of thought. Present controversies concerning evidence for exobiology and biogenesis have many aspects which reflect this millennial debate. Therefore this paper traces a selected history of this debate with some modern, 20th century developments due to quantum mechanics. It ¯nishes with an application of quantum information theory to several exobiology debates. Keywords: Biogenesis, Abiogenesis, Aristotle, Epicurus, Materialism, Information Theory 1. INTRODUCTION & ANCIENT HISTORY 1.1. Plato and Aristotle Both Plato and Aristotle believed that purpose was an essential ingredient in any scienti¯c explanation, or teleology in philosophical nomenclature. Therefore all explanations, said Aristotle, answer four basic questions: what is it made of, what does it represent, who made it, and why was it made, which have the nomenclature material, formal, e±cient and ¯nal causes.1 This aristotelean framework shaped the terms of the scienti¯c enquiry, invisibly directing greek science for over 500 years. For example, \organic" or \¯nal" causes were often deemed su±cient to explain natural phenomena, so that a rock fell when released from rest because it \desired" its own kind, the earth, over unlike elements such as air, water or ¯re.

  • How Is Industrial Nitrogen Gas (N2) Produced/Generated?
    www.IFSolutions.com 1 What is Nitrogen and How is it Produced Nitrogen (N2) is a colorless, odorless gas which makes up roughly 78% of the earth’s atmosphere. Nitrogen is defined as a simple asphyxiant having an inerting quality which is utilized in many applications where oxidation is not desired. Nitrogen gas is an industrial gas produced by one of the following means: !! Fractional distillation of liquid air (Praxair, Air Liquide, Linde, etc) !! By mechanical means using gaseous air "! Polymeric Membrane "! Pressure Swing Adsorption or PSA www.IFSolutions.com 2 Fractional Distillation (99.999%) Pure gases can be separated from air by first cooling it until it liquefies, then selectively distilling the components at their various boiling temperatures. The process can produce high purity gases but is very energy-intensive. www.IFSolutions.com 3 Pressure Swing Adsorption (99 – 99.999%) Pressure swing adsorption (PSA) is a technology used to separate some gas species from a mixture of gases under pressure according to the species' molecular characteristics and affinity for an adsorbent material. It operates at near-ambient temperatures and differs significantly from cryogenic distillation techniques of gas separation. Specific adsorptive materials (e.g., zeolites, activated carbon, molecular sieves, etc.) are used as a trap, preferentially adsorbing the target gas species at high pressure. www.IFSolutions.com 4 Membrane (90 – 99.9%) Membrane Technology utilizes a permeable fiber which selectively separates the air depending on the speeds of the molecules of the constituents. This process requires a conditioning of the Feed air due to the clearances in the fiber which are the size of a human hair.

  • Infrared Spectroscopy of Matrix-Isolated Polycyclic Aromatic Hydrocarbon Ions
    J. Phys. Chem. A 2000, 104, 3655-3669 3655 Infrared Spectroscopy of Matrix-Isolated Polycyclic Aromatic Hydrocarbon Ions. 5. PAHs Incorporating a Cyclopentadienyl Ring† D. M. Hudgins,* C. W. Bauschlicher, Jr., and L. J. Allamandola NASA Ames Research Center, MS 245-6, Moffett Field, California 94035 J. C. Fetzer CheVron Research Company, Richmond, California 94802 ReceiVed: NoVember 5, 1999; In Final Form: February 9, 2000 The matrix-isolation technique has been employed to measure the mid-infrared spectra of the ions of several polycyclic aromatic hydrocarbons whose structures incorporate a cyclopentadienyl ring. These include the cations of fluoranthene (C16H10), benzo[a]fluoranthene, benzo[b]fluoranthene, benzo[j]fluoranthene, and benzo- [k]fluoranthene (all C20H12 isomers), as well as the anions of benzo[a]fluoranthene and benzo[j]fluoranthene. With the exception of fluoranthene, which presented significant theoretical difficulties, the experimental data are compared to theoretically calculated values obtained using density functional theory (DFT) at the B3LYP/ 4-31G level. In general, there is good overall agreement between the two data sets, with the positional agreement between the experimentally measured and theoretically predicted bands somewhat better than that associated with their intensities. The results are also consistent with previous experimental studies of polycyclic aromatic hydrocarbon ions. Specifically, in both the cationic and anionic species the strongest ion bands typically cluster in the 1450 to 1300 cm-1 range, reflecting an order-of-magnitude enhancement in the CC stretching and CH in-plane bending modes between 1600 and 1100 cm-1 in these species. The aromatic CH out-of- plane bending modes, on the other hand, are usually modestly suppressed (e 2x - 5x) in the cations relative to those of the neutral species, with the nonadjacent CH modes most strongly affected.

  • Measurement of Cp/Cv for Argon, Nitrogen, Carbon Dioxide and an Argon + Nitrogen Mixture
    Measurement of Cp/Cv for Argon, Nitrogen, Carbon Dioxide and an Argon + Nitrogen Mixture Stephen Lucas 05/11/10 Measurement of Cp/Cv for Argon, Nitrogen, Carbon Dioxide and an Argon + Nitrogen Mixture Stephen Lucas With laboratory partner: Christopher Richards University College London 5th November 2010 Abstract: The ratio of specific heats, γ, at constant pressure, Cp and constant volume, Cv, have been determined by measuring the oscillation frequency when a ball bearing undergoes simple harmonic motion due to the gravitational and pressure forces acting upon it. The γ value is an important gas property as it relates the microscopic properties of the molecules on a macroscopic scale. In this experiment values of γ were determined for input gases: CO2, Ar, N2, and an Ar + N2 mixture in the ratio 0.51:0.49. These were found to be: 1.1652 ± 0.0003, 1.4353 ± 0.0003, 1.2377 ± 0.0001and 1.3587 ± 0.0002 respectively. The small uncertainties in γ suggest a precise procedure while the discrepancy between experimental and accepted values indicates inaccuracy. Systematic errors are suggested; however it was noted that an average discrepancy of 0.18 between accepted and experimental values occurred. If this difference is accounted for, it can be seen that we measure lower vibrational contributions to γ at room temperature than those predicted by the equipartition principle. It can be therefore deduced that the classical idea of all modes contributing to γ is incorrect and there is actually a „freezing out‟ of vibrational modes at lower temperatures. I. Introduction II. Method The primary objective of this experiment was to determine the ratio of specific heats, γ, for gaseous Ar, N2, CO2 and an Ar + N2 mixture.

  • Liquid Argon
    Safetygram 8 Liquid argon Liquid argon is tasteless, colorless, odorless, noncorrosive, nonflammable, and extremely cold. Belonging to the family of rare gases, argon is the most plentiful, making up approximately 1% of the earth’s atmosphere. It is monatomic and extremely inert, forming no known chemical compounds. Since argon is inert, special materials of construction are not required. However, materials of construction must be selected to withstand the low temperature of liquid argon. Vessels and piping should be designed to American Society of Mechanical Engineers (ASME) specifications or the Department of Transportation (DOT) codes for the pressures and temperatures involved. Although used more commonly in the gaseous state, argon is commonly stored and transported as a liquid, affording a more cost-effective way of providing product supply. Liquid argon is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid argon has a boiling point of –303°F (–186°C). The temperature difference between the product and the surrounding environment, even in winter, is substantial. Keeping this surrounding heat from the product requires special equipment to store and handle cryogenic liquids. A typical system consists of the following components: a cryogenic storage tank, one or more vaporizers, a pressure control system, and all of the piping required for fill, vaporization. The cryogenic tank is constructed, in principle, like a vacuum bottle. It is designed to keep heat away from the liquid that is contained in the inner vessel. Vaporizers convert the liquid argon to its gaseous state. A pressure control manifold controls the pressure at which the gas is fed to the process.

  • Inhibition of Premixed Carbon Monoxide-Hydrogen-Oxygen-Nitrogen Flames by Iron Pentacarbonylt
    Inhibition of Premixed Carbon Monoxide-Hydrogen-Oxygen-Nitrogen Flames by Iron Pentacarbonylt MARC D. RUMMINGER+ AND GREGORY T. LINTERIS* Building and Fire Research Laboratory, National Institute of Standards and Technology, Gaithersburg, MD 20899, USA This paper presents measurements of the burning velocity of premixed CO-HrOrNz flames with and without the inhibitor Fe(CO)s over a range of initial Hz and Oz mole fractions. A numerical model is used to simulate the flame inhibition using a gas-phase chemical mechanism. For the uninhibited flames, predictions of burning velocity are excellent and for the inhibited flames, the qualitative agreement is good. The agreement depends strongly on the rate of the CO + OH <-> COz + H reaction and the rates of several key iron reactions in catalytic H- and O-atom scavenging cycles. Most of the chemical inhibition occurs through a catalytic cycle that converts o atoms into Oz molecules. This O-atom cycle is not important in methane flames. The H-atom cycle that causes most of the radical scavenging in the methane flames is also active in CO-Hz flames, but is of secondary importance. To vary the role of the H- and O-atom radical pools, the experiments and calculations are performed over a range of oxygen and hydrogen mole fraction. The degree of inhibition is shown to be related to the fraction of the net H- and O-atom destruction through the iron species catalytic cycles. The O-atom cycle saturates at a relatively low inhibitor mole fraction (-100 ppm), whereas the H-atom cycle saturates at a much higher inhibitor mole fraction (-400 ppm).

The electrons are not shared equally between the hydrogen and oxygen atoms of water creating a Polar molecule. 2. The polarity of water allows it to dissolve most substances. Because of this it is referred to as the universal solvent 3. Water molecules stick to other water molecules. This property is called cohesion. 4. Hydrogen bonds form between adjacent water molecules because the positive charged hydrogen end of one water molecule attracts the negative charged oxygen end of another water molecule. 5. Water molecules stick to other materials due to its polar nature. This property is called adhesion. 6. Hydrogen bonds hold water molecules closely together which causes water to have high surface tension. This is why water tends to clump together to form drops rather than spread out into a thin film. 7. Condensation is when water changes from a gas to a liquid. 8. Sublimation is when water changes from a solid directly to a gas. 9. Freezing is when water changes from a liquid to a solid. 10. Melting is when water changes from a solid to a liquid. 11. Evaporation is when water changes from a liquid to a gas. 12. Why does ice float? Water expands as it freezes, so it is LESS DENSE AS A SOLID. 13. What property refers to water molecules resembling magnets? How are these alike? Polar bonds create positive and negative ends of the molecule.
