Abstract:

Inert gas agents have the potential to be widely used in fire suppression systems due to health and safety concerns associated with active chemicals. To suppress fire while minimizing hypoxic effects in an occupied area, the discharge quantity of inert gas agents should be carefully designed to dilute the oxygen concentration to a specific threshold level. In this study, the general expressions between oxygen concentration, the discharge rate of inert gas agents, and the ventilation rate of the air-agent mixture are derived first. Then, explicit formulas to calculate the discharge/ventilation rate and the required quantity of inert gas agents are given if the discharge rate and ventilation rate both are constants. To investigate the dilution and fire extinguishing efficiencies of inert gas agents, two scenarios with a discharge of inert gas agents into an enclosure are modeled using the Fire Dynamic Simulator (FDS). The simulation results show that the average oxygen mass fraction approximately reaches the design level at the end of the discharge period. Variation in oxygen concentration along the enclosure height is analyzed. For the scenario with a fire source, oxygen mass fraction decreases fast as oxygen is consumed by the combustion process. Thus, the fire is extinguished a little earlier than the end of the discharge period.

Abstract:

Semiconductor manufacturing fabs use ultra-high-purity (UHP) oxygen for various process applications such as oxide growth, plasma etch, and chemical vapor deposition. Moisture is identified as one of the key impurities that can affect device production. Moisture drydown in inert gas delivery systems was studied extensively. However, moisture drydown or outgassing characteristics in oxygen were found to be different from those of inert gas systems. Moisture adsorption and desorption in UHP oxygen systems were studied using advanced APIMS techniques for trace-level moisture analysis. To understand moisture reaction pathways, isotopic water was used as an adsorbate on 316L electropolished stainless steel (EPSS) surfaces. Experimental results from moisture drydown in the EPSS tubing were used to validate a theoretical model developed to predict the moisture drydown performance of large-scale, oxygen distribution systems. Both experimental and model results were shown to be useful in UHP oxygen system design, cost control, metrology, and contamination control.

Abstract:

Regarding INERGEN Clean gas Total Flood Fire Suppression System, these systems are specifically engineered for total flooding application in either unoccupied or occupied areas, but against its design, or their proved long term efficiency and global scale usage, since INERGEN agent is stored as a gas, it discharges as an invisible gas that can have a more destroying impact than the fire itself. Since 2008 up to now, there have been recorded on yearly basis several reports about INERGEN gas discharges conducting to faults in hard discs (HDD) operating in Data Centres protected by such a solution from fire due to the level of noise produced. The paper shows an analysis of this problem as hard disks damaging source detection and optimization by modelling of nozzle placement in the space choice as a technical solution to avoid these fire extinguisher side effects.

Abstract:

Echocardiography in the intensive care unit (ICU) is notorious for being difficult to perform, leading to frustratingly non-diagnostic studies with a lack of confidence in findings. The use of ultrasound contrast to enhance these images has the potential to salvage inconclusive studies and change management in critically ill patients. Ultrasound contrast, once ‘activated’, produces tiny microspheres containing an inert gas with a stabilizing shell with a diameter of approximately 1–5 μ‎m. Injected intravenously they pass through the pulmonary microcirculation into the systemic circulation. They last approximately 3–5 minutes and remain entirely in the vascular space. The gas is released unchanged by the lungs and the stabilizing shell is typically metabolized by the reticuloendothelial system or by fatty acid metabolism. These agents are essentially safe in the critically ill. Minor side effects occur in 1–2% and are alleviated by ceasing administration. There is a 1 in 10 000 chance of an anaphylaxis-type reaction and hence cardiopulmonary monitoring for at least 30 minutes after administration is recommended, along with suitable resuscitation measures to deal with this unlikely occurrence. Contrast-enhanced echocardiography can help to accurately detect the endocardial border, ventricular dysfunction, regional wall motion abnormalities, left ventricle thrombi, abnormal masses, and enhance Doppler signals among other potential benefits. In addition, the use of contrast can prevent further investigations and transfer which may be detrimental to the critically ill patient.

Abstract:

The four giant planets in the outer solar system, Jupiter, Saturn, Uranus, and Neptune, are a distinct group by themselves. The essential astronomical and atmospheric aspects of these planets are summarized in table 5.1. The significance of this group in the chemistry of the solar system is briefly pointed out in chapter 4. These planets are composed primarily of the lightest elements, hydrogen and helium, which were captured from the solar nebula during formation. The planets have rocky cores made of heavier elements. In the case of Jupiter and Saturn the mass of the gas greatly exceeds that of the core, whereas for Uranus and Neptune the masses of gas and core are comparable. Due to the enormous gravity of the giant planets, little mass has escaped from their atmospheres. Hence, the bulk composition of these planets provides a good measure of the initial composition of the solar nebula from which they were derived. Of all planetary bodies in the solar system, the constituents of giant planets are the closest to the cosmic abundances of the elements. The chemistry of the atmospheres of the giant planets is interesting for the following reasons:… 1. chemistry in a dominantly reducing atmosphere 2. interplay between photochemistry and equilibrium chemistry 3. ion chemistry in polar auroral regions 4. heterogeneous chemistry of aerosols 5. chemistry of meteoritic debris 6. lack of a planetary "surface"… We briefly comment on these reasons in this section. Each topic will receive a more detailed treatment in later sections. First of all, the atmospheres of the Jovian planets are more than 90% hydrogen and helium. Since helium is inert, the atmospheric chemistry is dominated by hydrogen. Therefore, we would expect the most stable compounds of carbon, oxygen, nitrogen, and phosphorus to be CH4, H2O, NHa, and PHs. This is in fact confirmed by the available observed composition of the bulk atmospheres of these planets. However, in the upper atmospheres of these planets, the composition is controlled by photochemistry.

Abstract:

A number of excellent descriptions of the techniques related to peptide chain assembly have already been published. These processes are also described in the operator manuals supplied by the peptide synthesis instrument manufacturers. Accordingly, the treatment of the subject presented here has been kept brief in order to provide more space in this volume for those topics not covered in detail in other publications of this type. The protocols have been written as they would be carried out using a manual peptide synthesis vessel. Whilst it is appreciated that most scientists preparing peptides will be using automated peptide synthesizers, it is not possible, given the wide variation in operating procedures, to describe how such methods may be applied to individual instruments. Particular emphasis has been given here to those operations which are typically carried out off-instrument, such as first residue attachment and peptide-resin cleavage. The operations described in this chapter can be carried out in a purpose-built peptide synthesis vessel or in a sintered glass funnel fitted with a three-way stopcock. The operation of the system is extremely simple: solvents are added from the top of the vessel, ensuring any resin adhering to the sides is rinsed down into the resin bed; the resin bed is agitated by setting the tap to position 1 to allow flow of nitrogen to the reaction vessel; solvents and reagents are removed by setting the tap to position 2 to connect the vessel to the vacuum. The use of such vessels has previously been described in detail. Peptide synthesis resins are extremely fragile and the beads, if wrongly handled, can easily fracture, leading to the generation of fines which can block reaction vessel filter-frits and solvent lines. It is particularly important that the correct method is used for mixing the resin and soluble reactants. Polystyrene-based supports are best agitated by bubbling an inert gas through the resin bed, or by shaking or vortexing the reaction vessel. Whilst all of these approaches are employed in commercial synthesizers, gas-bubbling and shaking are the most appropriate for use in manual synthesis.

Abstract:

It’s certainly not intuitively obvious that the noble gases, which don’t do anything, which don’t react either chemically or biologically, should be intimately related with questions of life and death, but so they are. The conventional wisdom is that they are physiologically inert: you breathe them in, you breathe them out; they don’t react with your body at all. This is not quite true. In 1938, two scientists at the Navy Experimental Diving Unit, Albert R. Behnke and Oscar D. Yarbrough, were working on the “remarkable stupefaction and neuromuscular impairment experienced by deep sea divers at depths below 100 feet” due to nitrogen narcosis. They discovered that substituting helium for atmospheric nitrogen in the air supply minimized the problem. The helium didn’t actually interact physiologically, but it improved the flow of oxygen through the aerobic pathways, according to Graham’s Law, which relates air flow to the inverse square root of the gas’s density (i.e., atomic mass). It seemed natural to investigate the role of argon, and the following year they found that, as expected, argon (being more dense than air) interfered with air flow rather than improving it. But further experiments showed, to their surprise, that argon was even more narcotic than nitrogen, an effect they ascribed to its increased solubility in both water and fat; that is, the effect on the central nervous system seemed to depend not so much on the identity of the gas but on its total dissolved concentration in the body and blood stream. Interesting, but soon there was a war on, and it wasn’t until 1946 that several workers at the University of California, Berkeley, took the obvious next step: the solubility of the noble gases increases with atomic number, so xenon should be most narcotic. And they found this to be so; indeed, xenon was so narcotic it worked as a general anesthetic on mice. Well, that was interesting.

Abstract:

Present study deals with experimental and theoretical performance analysis of an inert gas generator(IGG) which can be used as an effective mean to suppress the fire. The system consists of a gas turbine engine and afterburning system with injection of water, exit nozzle to produce the inert gas. It is generally known that the degree of oxygen content in the product of combustion depends on both inlet and outlet temperature of a combustor. Less the oxygen content in the combustion product higher will be the effectiveness of fire suppression. Injection of water brings additional advantages of suffocating and cooling effects which are both indespensable factors for fire suppressing. The special test rig was manufactured and experimental investigation of IGG system has been carried out. The automatic control system ensured stable operation of gas turbine engine and afterburner, water injection, fuel control and others. During the investigation the main parameters of gas turbine engine and auxiliarly systems were measured: gas temperature and pressure at gas turbine and afterburner exit, fuel flow rate, water mass flow rate, inlet air temperature, water temperature in the cooling chamber, mass flow rate, temperature and velocity of exhaust gas-steam mixture in the exit nozzle, oxygen content in the exit jet. The experimental investigation shows that developed IGG system can work very well for indoor fires but need some modifications in application to outdoor fire suppressing.

Abstract:

This paper details the work carried out to complete a Formal Safety Assessment (FSA) to assess the effectiveness of inert gas systems (IGS) in reducing the risk associated with cargo tank fire and explosions on chemical and oil tankers &lt;20,000dwt. Two different IGSs are considered; N2 for chemical tankers and conventional oil burning type for oil tankers. N2 IGS is required on chemical tankers to preserve the quality of the chemicals transported on these ships. These IGS systems are evaluated with Cost Benefit Assessments (CBA) to ascertain their cost effectiveness with regards to reducing potential loss of life, potential loss of cargo, potential pollution and potential loss of property. In this respect, the Gross Cost of Averting a Fatality (GCAF) and Net Cost of Averting a Fatality (NCAF) are calculated using the standard FSA method recognized by the International Maritime Organization (IMO). Further, the Cost of Averting one Tonne of oil Spilled (CATS) (Skjong et al., 2005 & Vanem et al., 2008) is applied to understand the cost effectiveness of IGSs in preventing environmental pollution. The risk reduction is estimated from detailed considerations of the accident statistics for tankers &gt;20,000dwt, where mandatory requirements for IGS was introduced in 1990. Comparison was made on risks resulting from accidents involving fire and/or explosion in the cargo tank of tankers of &gt;20,000dwt for the period of 1978–1983, in which most such tankers were not provided with IGS; and for the period 1990–2005, in which all such tankers were provided with IGSs under the requirement of SOLAS Chapter II-2. The paper further assumes that tankers &lt;20,000dwt that carry cargo with flashpoint &lt;60°C should have IGS installed, whilst ships without IGS may continue carrying cargo with flashpoint &gt;60°C. This way the question of requiring IGS is answered based on real risk of fire and explosion, and avoid introducing a rather arbitrary limit based on size of the ships.

Full text

Abstract:

The application of dynamic flying height (DFH) control technology to hard disk drives (HDDs) reduces the clearance of the magnetic heads above the disk surface to a few nanometers. Further, such a small clearance distance sometimes causes wear of the diamond like carbon (DLC) overcoat on the slider surface at the head–disk interface (HDI) owing to contact with the disk surface. The wear mechanisms of the DLC overcoat are considered to be either mechanical wear or tribochemical wear (oxidation of carbon) [1]. Recently, a helium-filled HDD was developed to improve the storage capacity and power consumption of HDDs. In the helium-filled HDD, tribochemical wear does not occur because there is no oxygen in the HDD. In addition, there is no humidity (water vapor), which was found to affect wear at the HDI [2]. Therefore, it is important to understand the effect of humidity and an oxygen-free inert gas environment on slider wear.

Full text

Abstract:

For closed-cycle gas turbines, in a size to meet utility power generation needs, the selection of helium as the working fluid represents the best solution in terms of the overall power conversion system considering the differing requirements of the turbomachinery and heat exchangers. Helium is well suited for the nuclear Brayton cycle because it is neutronically inert. The impact of helium’s unique properties on the performance and size of the power conversion system components is discussed in this paper. The helium gas turbine plants, that have operated were based on 1950s and 1960s technology, represent a valuable technology base in terms of practical experience gained. However, the design of the Gas Turbine Modular Helium Reactor (GT-MHR), which could see utility service in the first decade of the 21st century will utilize turbomachinery and heat exchanger technologies from the combustion gas turbine and aerospace industries. An understanding of how the design of power conversion systems for closed-cycle plants and combustion gas turbines are affected by the working fluids (i.e., helium and air, respectively) is the major theme of this paper.

Full text

Abstract:

One approach to improving steam cycles is to apply certain gas turbine technology, namely, direct combustion to achieve a high working temperature. Direct combustion supplies heat and also working fluid, without the need for high temperature heat exchange. By burning hydrogen with pure oxygen the only product of combustion is steam; consequently, no inert gas is introduced into the system. In a similar manner direct combustion is used to maintain temperature during the first part of the expansion so as to approach an isothermal expansion rather than the adiabatic expansion typical of steam systems. Such a modified steam cycle is described in this paper and shows a projected fuel efficiency of 58% when the maximum temperature is 1093 C., or 50% for 815 C. maximum. Practical ways to supply hydrogen and oxygen are discussed.
