Novel Drying Process Based on Self-Heat Recuperation Technology

Co-production of Bioethanol and Power

“…Moreover, this characteristic of the drying process is the same as for the thermal and distillation processes. Therefore, a drying process based on self-heat recuperation technology was recently proposed (Fushimi et al, 2011). Figure 6 a) shows a schematic image of a self-heat recuperative drying process.…”

“…However, to realize co-production, it is necessary to analyze and optimize the heat and power required for production in each process. Therefore, the authors have developed self-heat recuperation technology based on exergy recuperation (Kansha et al 2009) and applied it to several chemical processes for coproduction (Fushimi et al 2011, Kansha et al 2010a, 2010b, 2010c, Matsuda et al2010. In this chapter, self-heat recuperation technology is introduced and applied to the separation processes in bioethanol production for co-production.…”

Some Recent Advances in Drying Technologies to Produce Particulate Solids

“…They pointed out that surface temperature must be known accurately in order to predict the drying rates in falling rate period. Superheated steam drying has been used to dry wide range of products including coal 43,44) , wood 45,46) , sludge 47) and variety of food products, mainly at reduced pressure [48][49][50] . Mujumdar has discussed the principles, advantages and limitations as well as diverse applications of superheated steam dr ying technologies in a number of papers and books 39,40,51) , including the Handbook of Industrial Drying 1) .…”

Numerical analysis of single and multiple particles of Belchatow lignite dried in superheated steam

“…One of the applications realizing such an idea is the superheated steam fluidized bed dryer [8,9]. In this concept, the drying system operating in a self-heat recuperation configuration enables the collection of steam from the moisture in the raw fuel, followed by the recirculation of its latent and sensible heat for the drying of another fuel portion [10,11]. By that means, the heat of the phase transition is not given off to the ambience, what results in the decline of energy consumption, thus elevating the thermal efficiency of the system.…”
