One of the most important contributions Japanese researchers is proposition superstructure concept. Umeda and coworkers proposed in 1972 a system structure for reaction-separation process which split ratios determine connecting flows. Later, this concept changed to parameter and, finally, superstructure. Since 1980, superstructure-based optimization has been very active field Process Systems En...

With expanding areas of applications, increasing needs for efficient cycles, and growing demands for efficient modeling, it has become essential to develop new systematic strategies for optimal design and operation of PSA systems. Although industrial usage of PSA is widespread, we observe a drought of any systematic methodology to design PSA cycles in PSA literature due to inherent complexity o...

Murataite sA3B6C2O22−x/2 ,F4̄3md, a derivative of an anion-deficient fluorite structure, has been synthesized as different polytypes as a result of cation ordering. Ion-beam-induced amorphization has been investigated by 1-MeV Kr2+ ion irradiation with in situ transmission electron microscopy. The critical amorphization dose was determined as a function of temperature and the degree of structura...

Chemical process synthesis methods and tools developed over the last several decades have reached a level of maturity that have provided advantage to practitioners in an environment of increased costs and shrinking margins. Future growth within the chemical process industries is likely to involve even keener competition with greater impact from factors such as raw material and energy availabili...
