Ammonia (NH3) emissions deriving from the management of livestock manure have a significant environmental impact, and therefore it is important to reduce them. Among available options, process NH3 stripping promising remove manures digestates recovering as mineral fertilizer (e.g., ammonium sulfate) that more widely adoptable on farms. The traditional takes place in batches; however, this study...

Three – Phase Sparged Reactors are widely used in Chemical, Bio-Chemical and Petrochemical Industrial processes. The advantages of these reactors include high mass and heat transfer rates,isothermal conditions and on-line catalyst addition and withdrawl. The high heat transfer rates of Three-Phase Sparged Reactors are particularly attractive for highly exothermic reactions where substantial red...

So far 22 criticality accidents have been reported (McLaughlin et al., 2000) including JCO accident in Japan. All cases took place with fuel solution or slurry except one case of metal fuel. It was not clear that what was actually happening during those criticality accidents except the JCO accident, for which a fission power profile was reproduced from a gammaray monitoring data (Tonoike et al....

An explosion occurred at a polyvinyl chloride (PVC) resin manufacturing plant. The explosion originated at an atmospheric storage vessel when it received a slurry discharge from a suspension polymerization reactor. The pressure rise caused by the uncontrolled flashing of superheated liquid vinyl chloride resulted in the complete separation of the roof from the tank shell. A cloud of vinyl chlor...

We report the synthesis of cerium oxide, cobalt oxide, mixed cerium, and cobalt oxides and a Ce-Co/Al₂O₃ membrane, which are employed as catalysts for the catalytic wet oxidation (CWO) reaction process and the removal of formaldehyde from industrial effluents. Formaldehyde is present in numerous waste streams from the chemical industry in a concentration low enough to make its recovery not econ...

The purpose of the study was to identify and predict optimized parameters for phosphoric acid production. This involved modeling crystal reactor, UCEGO filter (as a detailed model is not available in Aspen Plus or other simulation software), separator using Sci-Lab develop Cape-Open models. conducted analyzing 10 different phosphates with varying qualities fractions P2O5 minerals. After success...

Supercritical water fluidized beds (SCWFBs) are promising and efficient reactors for the gasification of coal in supercritical water. The understanding investigation multi-phase flows as well process usually rely on time-consuming experiments or numerical simulations, which prohibit fast full exploration single coupled effects operation geometric parameters. To this end, paper builds an surroga...
