WHEN the collection of faeces during a metabolic experiment extends over a considerable period of time, difficulties arise in the determination of the total nitrogen and sulphur contents. Sampling of the wet composite specimen is generally unsatisfactory and ordinary methods of drying on a steam-bath result in a considerable loss of both nitrogen (as ammonia) and sulphur (mainly as sulphide). I...

Abstract In the present work, effect of forced air supply on combustion process liquid hydrocarbons was studied using diesel fuel as an example. The content flame intermediate components and temperature distribution along symmetry axis were atmospheric burner in which is atomized by a steam jet. gas composition equilibrium products heat release also investigated. influence excess ratio chamber ...

Abstract Low pressure superheated H 2 -steam appears to be an interesting alternative pressurized water environments, since it is capable of performing accelerated environmentally assisted cracking (EAC) experiments for nickel base and stainless steel alloys. Constant Extension Rate Tensile (CERT) tests were performed with displacement rates 2×10 -6 or -8 ms -1 at 350, 400, 440 480 °C on flat t...

In present work, study to obtain granulated active carbon based on industrial petroleum coke of the CEL grade (coke with an increased content volatile substances) produced in delayed coking unit have been conducted. The production activated carbons was carried out by preliminary carbonization at a temperature 500-800 °C, followed activation water vapor atmosphere 850-900 °C. addition, tests wer...

Studies on the durability and dimensional stability of a series of hardwoods and softwoods after thermal modification in vegetable oils and in steam atmospheres have been performed. Mass loss after exposure to Coniophora puteana (BAM Ebw.15) for 16 weeks was very low for European birch, European aspen, Norway spruce, and Scots pine thermally modified in a linseed oil product with preservative (...

We present a model of a geothermal system supplied at depth by saturated steam. It is shown that as steam rises from depth to lower pressure regions, liquid forms for pressures greater than 3.1 MPa. Once the pressure reaches 3.1MPa and the steam continues to rise into even lower pressure regions, it becomes superheated. Condensate does not form in the zone where pressures are less than 3.1MPa. ...

An experimental study has been conducted to investigate the turbulent mixing and heating caused by a (superheated) steam jet injected into a turbulent cross-flow of water in a square channel. The velocity field in the mid plane of the channel has been measured by means of particle image velocimetry for several different values of the ratio of the momentum fluxes of steam and water and various b...

Duan, et al. (1992a, 1992b) developed an equation of state (EOS), similar to that of Lee and Kesler (1975), that describes P-V-T-X relations in the system H2O-CO2-CH4 over the range 50-1000 C / 0–1000 bar (0-1000 C / 08000 bar for single component fluids). An extensive comparison of values calculated with this EOS and experimental P-V-T-X and solvus data was published by Nieva and Barragán (200...
