Design and optimization of reactive distillation: a review

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 6,   Pages 799-818 doi: 10.1007/s11705-021-2128-9

Abstract: Reactive distillation process, a representative process intensification technology, has been widely appliedHowever, due to the strong interaction between reaction and separation, the extension of reactive distillationTo overcome this problem, the design and optimization of reactive distillation have been widely studiedand illustrated for plenty of reactive mixtures over the past three decades.These design and optimization methods of the reactive distillation process are classified into three

Engineering 2015, Volume 1, Issue 2,   Pages 225-233 doi: 10.15302/J-ENG-2015041

Abstract:

Conventionally, an experimentally determined phase diagram requires studies of phase formation atdiagram of an entire composition spread of a binary or ternary system at a single temperature on onediagram.In this paper, we propose a "one-chip method" to construct a complete phase diagram by individuallydiagram to be mapped on one chip in a single experiment.

Neutron Diffraction Investigation of the DyFe11Ti Magnetic Structure and Its Spin Reorientations Article

Olivier Isnard, Eder J. Kinast

Engineering 2020, Volume 6, Issue 2,   Pages 153-157 doi: 10.1016/j.eng.2019.11.009

Abstract:

In this article, we report on the magnetic structure of DyFe11Ti and its thermal evolution as probed by neutron powder diffraction. A thermodiffraction technique was used to follow the temperature dependence of the magnetic moments, as well as their orientation. The Dy and Fe moments were coupled to each other in an antiparallel manner to form a ferrimagnet, where the easy magnetization direction at 2 K was the [110] axis in the basal (a, b) plane. This magnetic structure underwent two successive spin reorientation phenomena with increasing temperature. A large Dy magnetic moment of 9.7 μB was obtained at low temperatures, and the magnitude decreased rapidly to 7.5 μB at 200 K. The largest Fe magnetic moment was observed on the Fe 8i position. A ThMn12-type crystal structure was preserved in the studied temperature range, despite the large changes of the magnetic structure. A sharp tilt was observed at the first-order spin reorientation, TSR1; the angle between the easy magnetization axis and the crystal c axis was reduced from 90° at 2 K to about 20° at 200 K (where c is the easy axis above 200 K); and the Dy and Fe magnetic moments maintained an antiparallel coupling.
