The vertical circulative impinging stream reactor

On the other hand, the SCISR also has some disadvantages. The first is that the operational impinging velocity is limited to an extent. An excessively high impinging 

In order to overcome these disadvantages and extend the application area, the vertical circulative impinging stream reactor (VCISR) was designed and patented [232] its structure is shown in Fig. 17.1. 

The major difference between the VCISR and the SCISR is the former s vertical structure, while the SCISR has a horizontal structure. This changes the flow configuration from horizontal impinging streams in the SCISR to vertical in the VCISR, and also the container form of the VCISR is changed to a cylinder. 

There is a jacket outside the reaction vessel for heat exchanging, which enables one to cool or heat the process mixture inside the reactor. When cooling the mixture, cold water or another cooling medium enters the jacket through the lower inlet tube (8) at the bottom and flows out through the upper outlet tube (9), while for heating the 

The VCISR can have a cover (12). By suitably designing the mechanical strength and the connecting mode, the reactor can be operated under pressure or vacuum, while for open operation, the cover can be removed.
