Riassunto analitico
The following thesis work has the aim to measure experimentally Raschig trays
pressure drops and carry out hydraulic and mass transfer measurements on selfmade
PVC-U sieve trays.
The rst part is focused on the valve pressure drops measurements of the
Raschig trays. In order to evaluate their performance, it has been conducted a
comparison between the measured values and two correlations found in literature.
Afterwards, starting from the Klein model, a correction function that is
able to describe and predict the dry pressure drops has been developed.
Secondly, PVC-U sieve trays (with segmental downcomers) have been designed
with the aim to carry out hydraulic and mass transfer and compare
these results with the correlations developed for the most commons stainless
steel trays.
