New type of the distillation sampling points

Sampling of the vapour and liquid phase from the packed bed of the distillation column is far from an easy task. The prototypes of the sampling points are depicted. Each type must be tested and the results compared with the standards. The internal name of the last iteration is “Sputnik 69” 

Development of H-metr

The work on the hydrogen analyzer progresses into the verification phase – long term stability of the probes is tested. Tomáš carefully records the measured signal – it must be stable for at least 90 days. The hydrogen probes are used for the measurement of the hydrogen fugacity in the primary loop of the nuclear powerplants. The hydrogen reacts with any traces of the oxygen – thus suppressing corrosion.    

We are preparing for the next distillation campaign

The #30 (summer 2019) experimental campaign will collect composition profiles along the packed bed of our i.d. 300 mm (R300) column distilling cyclohexane/n-heptane mixture under the pressures of 33 kPa, 101 kPa and 180 kPa. The packed bed consists of 12 elements of Mellapak 452.Y packing, we have recently increased number of the sampling points from six to ten. We are proudly awaiting the results, which will be worldwide unique!  Many thanks to Prof. Dali Šnita for the manufacture of the sampling points parts during Continue reading →
