Hashimoto process

Concerning the level of integration, classical flowsheet-integrated processes as reactor-separator-recycle systems (Fig. 3a) and the use of side reactors ( Hashimoto process . 

The Hashimoto process (b) was formd to be infeasible for 99.9% purity. In fact, the process is thermodynamically infeasible for the production of pure A. The scheme achieves only low performance for 90% purity. This is in agreement with literature [2]. The hypothetical option of a fully integrated process with distributed reactivity (c) allows for a significant improvement of process performance. This holds in particular for component A, where SR and EC are strongly reduced. The main reason is that here the required 3 / -value is 16% lower than in case (a) m [ is even lower than the Henry constant of B. The explanation is that any B in the reactive zone I also reacts to produce A, which is desorbed more easily and transported towards the non-reactive zones. A similar benefical effect (which is somewhat less pronounced) is found for m [v, which is higher for the fully integrated schemes than for the flowsheet-integrated processes. 

The Hashimoto process design separates the functionalities separation and reaction. This concept offers the possibility to exchange adsorbent and, for example,... 

Both four-section processes achieve similar productivities. For fructose syrup purities of up to 95% the productivity of the Hashimoto process is slightly higher. If purities higher than 95 % are required the non-integrated sequential process is slightly favorable. This concept also allows the highest purities of fructose syrup of all.

It is also reported that anions can be preferentially adsorbed in the CBD process, which leads to different levels of impurities. Hashimoto et al.28 compared the iodide and chloride impurities in the CBD CdS thin films when the films were deposited from an aqueous solution of iodides and chlorides, respectively. The CdS films deposited using iodide contained 3% iodine, whereas the CdS grown from chlorides contained less than 1% chlorine.
