A study was conducted to determine the effects of solid‐liquid separation of liquid swine manure on ammonia emissions from lagoons. This determination was done at full‐scale in two contiguous swine production units that had similar animal production management. One of these units was maintained as a control using the anaerobic lagoon treatment method. In the second production unit, solids were ...

organic solvents. In this study, NiFe2O4/sawdust nanocomposite was synthesized for removingoil pollutants. The oil-adsorbing nanocomposite could be easily separated from water bymagnet bar. The XRD results show tetragonal phase proving the composite formation. TheFESEM pictures successfully reveal the growth of NiFe2O4 on the sawdust template. The FTIRbands at 422 cm-1 and 615 cm-1correspond to...

Oxygen carrier aided combustion is a process that utilizes oxygen carrying particles in fluidized bed to transport from oxygen-rich oxygen-poor regions the reactor. A commonly used oxygen-carrying material ilmenite (FeTiO3) which naturally occurring mineral. At higher partial pressures can react pseudobrookite (Fe2TiO5) and thereby take up oxygen. Upon reduction of oxygen-lean locations release...

Onboard air separation devices, based on hollow fiber membranes, are traditionally used for the optimization of aircraft fuel tank inerting systems. In present study, a set tests have been designed and executed to assess performances these systems different inlet temperatures (70°C∼110°C), pressures (0.1∼0.4 MPa), volume flow rates nitrogen-enriched (NEA) (30∼120 L/min) flight altitudes (1.5∼18...

Aiming to sequestrate the excessive carbon dioxide and convert acidified seawater, an improved method of mineralization is developed based on electrode separation mechanism extra oxygen-supplying technique. By neutralizations anodic acidity cathodic alkalinity, as well precipitation dissolution calcium carbonate (CaCO3), are prevented. In addition, extra-supplied oxygen prevents evolution hydro...

With the increasing importance of “ heavy water” as a moderator in nuclear reactors there arises a pressing need for a more efficient method of separating hydrogen isotopes. In a report by 0. N. Salmon to the U.S. Atomic Energy Commission (AEC Research and Development Report KAPL 1272) a process is described which aims to improve the method of separation by the electrolysis of water. This proce...

Blood from a woman with unexplained erythrocytosis had increased oxygen affinity, but no abnormality could be detected by electrophoresis or chromatography of her hemolysate. Separation of the tryptic peptides of her beta chains disclosed two half-sized peaks in the regions of beta T-11. The faster of these was abnormal, with the structure beta 101 Glu replaced by Asp. The new hemoglobin was ca...

The influence of thermal annealings on La(0.9)Ca(0.1)MnO(3) (LCMO) films in oxygen and in vacuum with low hole doping is investigated in the phase separation region where competition between AFM and FM phases is high. Measurements by x-ray diffractometry, atomic force microscopy and magnetometry reveal changes in the lattice parameters and magnetic properties of the films, depending on the oxyg...

Flow analysis at microvascular bifurcation after partial replacement of red blood cell (RBC) with liposome-encapsulated hemoglobin (LEH) was performed using the lattice Boltzmann method. A two-dimensional symmetric Y bifurcation model with a parent vessel diameter of 20 mum and daughter branch diameters of 20 microm was considered, and the distributions of the RBC, LEH, and oxygen fluxes were c...

In this work it is analyzed the performance of an iron waste material as oxygen carrier for a chemical-looping combustion (CLC) system. CLC is a novel combustion technology with the benefit of inherent CO2 separation that can be used as a source of energy for the methane steam reforming process (SR). The tail gas from the PSA unit is used as fuel in the CLC system. The oxygen carrier behaviour ...
