Elemental sulfur (S8) is often present in considerable amounts in sour gas reservoirs at the reservoir conditions (pressure and temperature). For the isothermal conditions in the reservoir, the reduction in reservoir pressure below a critical value will cause the elemental sulfur to deposit in the formation. Sulfur deposition can cause severe loss in the pore space available for gas, and in tur...

In connection with the problem of the determination of the cardiac output by the use of ethylene (13), it seemed of interest to investigate further the nature of the forces which make the solubility of this gas 1% times as great in human blood as it is in water. The general problem of the nature of the factors which determine the solubility of gases in blood is of importance not only because of...

A simple and rapid in vitro chemical solubility test applicable to industrial uranium trioxide (UO3) was developed together with two in vitro cellular tests using rat alveolar macrophages maintained either in gas phase or in alginate beads at 37 degrees C. Industrial UO3 was characterized by particle size, X-ray, and IR spectra, and chemical transformation (e.g., aging and hydration of the dust...

The solubility of nitrous oxide in blood at body temperature was determined by Siebeck (1) with considerable accuracy as early as 1909. In his experiment, the blood was placed with a gas mixture in a tonometer of 3 liters capacity and equilibrated at 38” and atmospheric pressure. After an equilibrium had been attained, samples of both blood and gas were analyzed for nitrous oxide content. A blo...

The various methods described in recent years for determining the cardiac output of man consist essentially either 1, in an application of the Fick principle, or 2, in measuring the rate with which either a normally present gas (nitrogen) or a foreign gas (nitrous oxide, ethyl iodide or ethylene) is exchanged during the passage of the blood through the lungs. Results obtained by the carbon diox...

There are a variety of approaches to removing gaseous pollutants from effluent streams: absorption, adsorption, condensation, chemical reaction, incineration, and selective diffusion through a membrane. Absorption is an operation involving mass transfer of a soluble vapor component to a solvent liquid in a device that promotes intimate contact between the gas and the liquid. The driving force f...

in this study, mass transfer coefficients (mtc’s) of natural gas components during hydrate formation are reported. this work is based on the assumption that the transport of gas molecules from gas phase to aqueous phase is dominant among other resistances. several experiments were conducted on a mixture of natural gas at different pressures and temperatures and the consumed gas was monitored an...

BACKGROUND Anesthetic blood solubility predicts pharmacokinetics for inhaled agents and is essential for determination of blood anesthetic concentrations from end-tidal gas concentrations using Henry's Law. Though used to model anesthetic effects in humans, there are limited interspecies solubility comparisons that include modern haloethers. This study aimed to measure hematocrit-adjusted blood...

The dissolution of invaded gas in the drilling fluid during results an increase invasion concealment. This is great significance for development acid reservoirs to determine solubility change and multiphase flow law annulus after by natural with high CO 2 content. In this study, control equations gas–liquid are established considering influence solubility. For prediction solubility, interaction...
