Improving Water Spray Efficacy for Fire Suppression via CO2 Addition at High Pressures and Low Temperatures: Evidence for CO2 Clathrate Hydrate Formation
This paper describes a technique for achieving a compact aqueous spray that incorporates CO2 into the spray at low temperatures (T < 10 °C) and high pressures (P > 10 MPa). A high-pressure spray apparatus was used to explore the effects of temperature (4-25 °C), nominal CO2 mole fraction (0-0.12), in-line filter pore size (0.5-7 μm), and additives on the high-pressure (12-19 MPa) water spray pa...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Experimental determination of the equilibria : rutile + magnesite = geikielite + CO 2 and zircon + 2 magnesite = baddeleyite + forsterite
The P-T conditions of both equilibria were determined precisely by reversal experiments in a piston-cylinder apparatus. On the basis of 8 experiments, brackets for the rutile-magnesite-geikielite equilibrium are 7.0–7.1 kbar at 800 ∞C, 8.6–8.7 kbar at 850 ∞C, and 10.5–10.7 kbar at 900 ∞C. On the basis of 9 experiments, brackets for the zircon-magnesite-baddeleyite-forsterite equilibrium are 7.1...
متن کاملEffect of H20-co2 Organization on Ovalbumin Adsorption at the Supercritical Co2-water Interface
We have previously investigated the formation of water-CO2 interface by means of a drop tensiometer [1]. In presence of CO2 , the interaction between the two adjacent phases leads to an organization of interfacial cluster network which controls the tension and the mechanical properties of the interface. The formation of those clusters at CO2 pressure lower than 80 bar inhibits the adsorption of...
متن کاملReaction kinetics and isotope effect of water formation by the surface reaction of solid H2O2 with H atoms at low temperatures.
We performed laboratory experiments on the formation of water and its isotopologues by surface reactions of hydrogen peroxide (H2O2) with hydrogen (H) atoms and their deuterated counterparts (D2O2, D) at 10-30 K. High-purity H2O2 (> 95%) was prepared in situ by the codeposition of molecular oxygen and H atoms at relatively high temperatures (45-50 K). We determined that the high-purity H2O2 sol...
