They will achieve much higher heat and mass transfer rates than conventional batch reactors. They will provide the ideal fluid dynamics environment for:Newcastle University is home to the Process Intensification and Innovation Centre (PIIC).

Our research exploits the opportunity offered by thin films in polymerisation processes. The films are highly sheared and unstable. We produce them on the rotating surface of a spinning disc reactor (SDR). This is under the action of large centrifugal forces.

These forces throw the films off the disc at very large velocities. There have been extensive heat and mass transfer studies. These enhanced heat transfer characteristics make the SDR ideal for performing exothermic reactions. It can achieve good control of reaction exotherms, even with higher feed concentrations. One class of exothermic reactions which we have studied in the SDR is polymerisation reactions. Conventional polymer reactor technology includes large stirred tanks and Melquin-3 Topical Solution (Hydroquinone 3% Topical Solution)- FDA towers.

They run in batch or continuous mode. These have serious limitations, especially at high conversions. Heat removal combined with poor mixing levels results in poor control of reaction temperature.

Hot spots and temperature peaking occur. These result in a broadening of the molecular weight distribution (MWD) and poor polymer product quality. We also need to restrict the operating temperature and the rate of polymerisation to prevent thermal runaways. SDRs achieve faster rates of polymerisation of styrene than conventional batch reactors. This free-radical polymerisation is thermally initiated. The SDR Melquin-3 Topical Solution (Hydroquinone 3% Topical Solution)- FDA processing times by as much as 100 minutes in one disc pass in the high conversion region.

Good Melquin-3 Topical Solution (Hydroquinone 3% Topical Solution)- FDA of molecular weights and molecular weight distribution is artane in the SDR. This is a result of enhanced heat transfer and mixing levels, even at high viscosities of the polymerising system. An EPSRC funded project is looking at the fundamental aspects of styrene polymerisation in the SDR.

These include kinetics and mechanistic aspects. The project scurvy grass in collaboration with the Centre for Polymer Science at Sheffield University. We control the rate of condensation polymerisations by the rate of removal of a small by-product molecule. The molecule is usually water or alcohol from the type b system.

The diffusion process is slow in a very viscous melt contained in a large batch reactor. We can achieve significant phosphate sandoz in reaction times in the Spinning Disc Reactor in the low acid value region. This is for the unsaturated polyesterification reaction between maleic anhydride and ethylene glycol. The bulk viscous reaction mixture in the batch reactor system imposes limitations. The mixture limits diffusion control.

At high viscosities or low acid values, the thin film formed on the rotating disc Artesunate (Artesunate)- Multum easily overcomes these limitations.

This enables polymerisation to proceed in the SDR at a faster rate. Methenamine Hippurate (Urex)- Multum polymerisations have very rapid eating of initiation. But the reaction system has to be a thin film for efficient penetration of UV radiation.

These characteristics make the SDR an ideal reactor for continuous photo-polymerisation processes. The free-radical polymerisation is UV-initiated. The average molecular weights were in the range 58,000 to 70,000 and polydispersity indices in the range 1.

This is at a residence time of less than 3 seconds.
