teurizers (1). I f these various precautions are not sufficient to produce a satisfactory steam supply, the alternative is the production of culinary steam from potable water, using the unsatisfactory primary steam supply as a source of heat. The 3A recommended practice just referred to includes a sketch of the recommended location of the parts necessary for such an installation. The other alte...
In this paper, Steam Assisted Gravity Drainage (SAGD) is introduced and its advantages over ordinary steam injection is demonstrated. A simple simulation model is built and three scenarios of natural production, ordinary steam injection, and SAGD are compared in terms of their cumulative oil production and cumulative oil steam ratio. The results show that SAGD can significantly enhance oil prod...
Abstract Corncob pyrochar activated with steam (CCA) and nonactivated corncob (NCC) were produced characterized. The performance of the best material was tested in a dual‐chambered microbial fuel cell (MFC) as an electrode for bioelectricity generation using wet torrefaction wastewater substrate. Pyrolysis 80.3 g dried corncobs carried out at 600°C under constant N 2 flow 3 L min −1 30 resultin...
This article reviews research related to the activation of methane by Ni and Ru using model catalysts, highlighting the surface science work carried out using molecular beams methods and elevated pressure reaction studies. Emphasis is placed on connecting the model studies of surface science with the corresponding results obtained on the analogous ‘real world’ catalysts. These combined studies ...
The dangers posed by non-condensable gases (NCGs) in steam sterilisation processes have long been underestimated. Biological indicators, or the best chemical indicators on the market, do not signal the presence of a NCG content of up to 10% in a sterilisation process so long as there is mixing of steam and NCGs in the sterilisation chamber. Already back in 1963, Bowie and Dick (1) demonstrated ...
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
Steam is a key energy vector for industrial sites, most commonly used for process heating and cooling, cogeneration of heat and mechanical power as a motive fluid or for stripping. Steam networks are used to carry steam from producers to consumers and between pressure levels through letdowns and steam turbines. The steam producers (boilers, heat and power cogeneration units, heat exchangers, ch...
DC lOO%-steam plasma characteristics were investigated for the application of halogenated hydrocarbon decomposition because steam plasmas are chemically reactive. However, plasma system generally requires complex subsystems such as steam generators and cooling units. The presented steam plasma system is a portable light-weight plasma generation system that does not require any gas supply unit. ...
There exists general agreement that the steam engine's rise in importance occurred at the same time as large increases in firm size and growing urbanization, but no consensus concerning the degree to which the steam engine served as an exogenous fo rce fueling urban growth. We reexamine the hypothesis that a leading brand of steam engine made by the Corliss Company fue led urbanization in the l...
The present investigation was undertaken to evaluate the adsorption effectiveness of pecan shell-based granular activated carbons (GACs) in removing metal ions (Cu(2+), Pb(2+), Zn(2+)) commonly found in municipal and industrial wastewater. Pecan shells were activated by phosphoric acid, steam or carbon dioxide activation methods. Metal ion adsorption of shell-based GACs was compared to the meta...
