Oscillation results in improved mixing through the formation of vortices. If a net flow is also superimposed on to this oscillatory motion, the reactor behaves like many well-mixed tanks-in-series.

Their niche application is the accommodation of long residence time processes. Continuous processing tends to be more efficient than batch processing. It is often at larger scales: it is an economy of scale. But it is seldom used for long reactions as conventional continuous reactor designs have certain drawbacks. Continuous stirred tank reactors (CSTRs) have broad residence time distribution. This leads to product variability, such as large particle size distributions. Plug flow reactors (PFRs) need great lengths of narrow tubing.

This causes control, operability, footprint and pumping problems. CSTRs-in-series tend to be expensive. This is because they need multiple reactors and control systems. A recent development is the mesoscale (or millimetre scale) OBR, first presented in 2003. This tubular reactor has a characteristic inner diameter of 4. The reactors of the future will operate under continuous rather than batch mode.

They will achieve much higher heat and mass transfer rates Quinidine Sulfate (Quinidine Sulfate Tablet, Film Coated, Extended Release)- FDA 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 Pramipexole (Mirapex)- Multum 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 Buprenorphine and Naloxone Sublingual Film (Cassipa)- Multum, 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 Buprenorphine and Naloxone Sublingual Film (Cassipa)- Multum unagitated 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 Buprenorphine and Naloxone Sublingual Film (Cassipa)- Multum 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 reduces processing times by as much as 100 minutes in one disc pass in the high conversion region.

At me a similar situation. I invite to discussion.

Bravo, your idea it is magnificent
