The sound speed of a two-phase fluid, such as a magma-gas, water-air, or water-steam mixture, is dramatically different from the sound speed of either pure component. In numerous geologic situations the sound speed of such two-phase systems may be of interest: in the search for magma reservoirs, in seismic exploration of geothermal areas, in prediction of P wave velocity decreases prior to eart...

The conversion of various solid low-cost fuels into valuable gas with high energy content is attracting increasing interest within the chemical industry and the energy supply sector. For the gasification of carbonic fuels, fluidized bed processing based on the dual fluidized bed concept is utilized preferably. Dual fluidized bed gasification technology greatly intensifies the conversion of the ...

Steamflood as one of thermal EOR method is effective to reduce the amount oil left in reservoir by mechanisms such reducing viscosity oil, evaporation, and displacement steam. In this method, fluid injected continuously into some injection wells displace obtain production from other wells. However, there are problems with steamflood process that still not optimally solved. There an early channe...

Nickel supported on SBA-15 doped with CeO2 catalysts (Ni-CeO2/SBA-15) was prepared, and used for steam reforming of toluene which was selected as a model compound of biomass gasification tar. A fixed-bed lab-scale set was designed and employed to evaluate the catalytic performances of the Ni-CeO2/SBA-15 catalysts. Experiments were performed to reveal the effects of several factors on the toluen...

Two novel system configurations were proposed for oxy-fuel natural gas turbine systems with integrated steam reforming and CO2 capture and separation. The steam reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel with oxygen as the oxidizer. Internal combustion is used, which allows a very high heat input temperature. Moreover, the turbine...

This demonstration project was intended to repower an existing plant facility, the Lakeside Station in Springfield, Illinois. A single Integrated Gasification Combined Cycle (IGCC) process train was planned to generate a net output of 60 megawatts. The plant consists of a combined cycle (gas turbine, heat recovery steam generator, steam turbine) power train located in the existing buildings and...

The main lessons of the major accident at Fukushima-Daiichi NPP in 2011 for nuclear power industry identify need to model, analyze and develop emergency measures relatively unlikely events with catastrophic environmental consequences, taking into account multiple failures safety systems. Steam-gas explosions became one causes consequences Chernobyl Fukushima accidents. Criteria conditions occur...

The purpose of this study was to investigate the effects of warm and cold physical as well as chemical processing methods on the nutritive value of barley grains by gas production technique. The processing methods included milling, steam flaking, extruding and soaking up the grain in water containing 1.00% citric acid, 1.00% propionic acid and 0.01 M sulfuric acid. Two-hundred mg of milling sam...
