How it Works?
- This gives precise control over heating and cooling cycle. Thus, not only the temperature is controlled as a critical process parameter but also the heating-and-cooling time is controlled as a critical parameter. This results in batch-to-batch consistency and higher yield.
- Single fluid heating cooling system is normally connected to a single reactor, where the Temperature of the system is varied as per the process requirement, Thus maintaining the constant temperature difference between the process and fluid temperature
Solution
- Single fluid heating cooling systems (SFHC) / Temperature Control Unit (TCU) are coming-up as an ideal solution to overcome most of the limitations with traditional multiutility based heat transfer and control system. where high accuracy and wide temperature ranges are critical for the development of new compounds and API’s.
SFHCS / TCU Usage
- Crystallization Reactions – For better productivity
- Non-Aqueous Reactions: Critical application where Aqueous utilities are to be not used for heating/cooling, which leads to hazardous conditions (e.g. reactions which involve materials like Sodium) – For Safety
- Applications where sudden temperature rise, causing thermal shocks.
- Alternate Heating & cooling process application (where utility change over is a wastage of time & tiresome job)
- Metal Reactions – For better batch-to-batch repeatability. Multi product plant
Advantages
- Repeatability and accurate recordable. Fully automatic capability, hence less manpower required.
- Programmable heating and cooling ramps for accurate unsupervised operations
- Rapid heating and chilling profiles can be designed, reducing batch times.
- No switching between jacket service fluids, preventing cross contamination, corrosion or thermal shocks to the vessel.
- Suitable for the very cold operating temperatures required by today’s new chemical formulae and reactions.
- Smooth, continuous temperature control, with no gaps because there is no fluid changeovers.
- Accurate temperature control to +/-1°C without risk to your reactor.
- Measurement for meeting FDA requirements.
- Savings on expensive raw materials can be made because the yield is maximized without adding excess reactions.
- No interruption of process and no hot spots, resulting in higher product yields and quality. Off batches are minimized, if not eliminated
Limitations
- Multiple utilities can corrode the reactor jacket.
- Different heat transfer fluids (HTFs) may require separate coils, heating and cooling jacket zones or external heat exchangers
- Process parameter deviations adversely affect product quality.
- Complicated mechanical design, and Increases capital/maintenance costs.
- Cross contamination of HTFs
- Inefficient management of HTFs leading to inaccurate temperature control.
- Condensate recovery is not feasible.
- Time consuming changeover of HTFs and associated risks of human error.
History
- Traditionally, this was being done with multiple utilities such as chilled brine, chilled water, cooling water, hot water, low pressure steam, high pressure steam, thermic fluid etc.
- Active Pharmaceutical Ingredient (API) manufacturing involves batch reaction, work-up, distillation, crystallization, hydrogenation, layer separation, filtration and drying as unit processes.
- Again, batch reaction involves heating and cooling stages ranging from -50°C to +250°C
