Chemical reactors Oscillatory Baffled

Formulation of multi-component emulsions and mixtures are of interest in chemical and industrial processes (Vilar, 2008 Vilar et al., 2008). Standard stirred tank reactors (STR) and oscillatory baffled reactors (OBR) are traditional methods for the formulation of liquid-liquid mixtures and liquid-solid emulsions. Compared with STR, oscillatory baffled reactors provide more homogeneous conditions and uniform mixing with a relatively lower shear rate (Gaidhani et al., 2005 Harrison and Mackley, 1992 Ni et al., 2000). Figure 17 is a sketch of a typical oscillatory baffled reactor. It consists of the reactor vessel, orifice plate baffles, and an oscillatory movement part. The orifice plate baffles play an important role in the OBR for the vertex generation in the flow vessels as well as the radial velocities of the emulsions and mixtures. They are equally spaced in the vessel with a free area in the center of each baffle... 

Process intensification (PI) offers several opportunities to improve energy efficiency and reduce environmental impact [92]. Many chemical reactions currently carried out as batch processes in stirred tanks could be carried out in continuously operated, intensified reactors such as spinning disc or oscillatory baffle types. The plant used for separations can be made highly compact, and even for large-scale plants (nitric acid production) the concept of pocket-sized plant has been introduced to reduce energy needs in the process [93]. PI is thus a key element...

The chemicals (bulk, fine and pharmaceutical) and offshore industrial sectors are not the sole preserves of process intensification, as has already been illustrated in this book. In this chapter the reader is introduced to other process industry sectors where PI has made significant inroads into unit operations. Some sectors adopted intensification techniques in advance of the chemical industry (e.g. nuclear reprocessing), others pioneered techniques, such as ultrasonics, decades before they became accepted in areas such as chemical reaction intensification (e.g. in metallurgy). The food sector uses microwaves routinely for speeding up cooking processes, and effluent treatment can benefit from oscillatory baffle reactors. Aerospace, although perhaps not regarded as a process industry, is also included in this chapter. 

NiTech offer industrial experience, expertise and practical know how on how to improve existing batch and continuous process using NiTech technology, as well as aiding in the development of new innovative processes. NiTech technologies are centered on the design and implementation of baffled chemical reactors and process reactors known as the Continuous Oscillatory Baffled Reactor (COBR ) and the Tubular Reactor (TBR ) (NiTech Solutions 2007).
