Continuous Stirred Tank Reactors
| Features |
| Volume : 500 ml to 1000 ltr |
| Pressure Range : up to 100 bar |
| Temperature Range : -30°C to 300°C |
| Flow Rate : Upto 10,000 lph |
| Material : SS316, Hastelloy C276 |
| Multiple CSTRs connected in series (cascaded setup) for faster reactions. |
| Sampling valves in each cell to monitor reaction progress. |
| Can handle slurries in high concentration. |
| Residence times could range from a few seconds to as high as few hours. |
| Working: Stirred tanks commonly used in the industry are completely back-mixed reactors meaning the concentration in the reactor is same as the outlet of the reactor – this greatly reduces the reaction rates. Plug flow reactors are an alternative to stirred tanks where the concentration varies in the axial direction of the reactor. Tubular reactors showcase a plug-flow behaviour but tubular reactors have couple of challenges |
| When it comes to handling concentrated slurries, tubular reactors can clog |
| Performing slow reactions: as mixing is compromised due to low velocities in the tubular reactors |
| In such cases, conventional CSTRs are chosen, however multiple CSTRs in series provide a plug-flow like behaviour and also help in increasing the reaction rates by limiting the back-mixing. At Amar, we design CSTRs or cascaded CSTRs from lab to commercial scale. |
