A study of TiO2 and Adipic acid crystallisation in the spinning disc reactor

 

In recent years, the spinning disc reactor (SDR) has been developed as process intensification equipment where rapid mass and heat transfer rates can be obtained from the thin film of liquid produced due to centrifugal acceleration of rotating disc. In developing these characteristics, the SDR is considered a tool of process intensification; compact, flexible, inherently safe, continuous and capable of delivering better product quality. An SDR and spinning disc reactor were previously investigated in the precipitation of barium sulphate crystals and calcium carbonate. It was noticed that high rapid mixing joined with high levels of supersaturation lead to very small crystals with a tighter size distribution being produced. This was considered to produce better quality than conventional process techniques actually used in the pharmaceutical industry.

This study aims to develop and demonstrate a novel processing method on the basis of the spinning disc reactor (SDR) for the production of titanium dioxide nanoparticles and crystallisation of Adipic Acid in order to enhance the efficiency and the higher quality products. The spinning reactor seems more desirable its considerably lower specific energy consumption. Additionally this technique is utilized to make high flow rate and very short residence time in continuous method. Exploratory works and primary studies show that the other important advantages of SDR technology is the increased number of particles with controlled size, shape and size distribution to reach quality requirements.
