Typically the standard sieve plate cartridge is characterised by sieve plates mm diameter sieve holes with an fractional open area of 23% placed 50 mm apart that of a 8 in column 8 in diameter column is considered so as to ensure the results obtained is typcial of an industrial scale pulsed column For validation a computational
sieve plate columns was proposed by Kumar and Hartland [7] A stagewise model for the transient behaviour of a sieve plate extraction column taking into account the back flow and assuming constant hold up was developed by Blass and Zimmerman [8] Hufnagl et al [9] evaluated a differential model of a Kühni column Steiner et al [10]
Holdup in a pulsed sieve plate column has also been validated by Yadav et al [9] The experimental tower on the industrial scale had two Nye trays and two chimney trays The results show good
The plate where the bubble is generated is made of stainless steel because most of the industrial sieve plates use this material or its alloys Moreover according to several authors Lin et al 1994; the behaviour of the growing bubble is different whether the plate is made of metal or plastic This work will deal with this matter because

A dynamic mathematical model is developed to simulate emulsion polymerization reactions carried out in a new type of reactor the pulsed sieve plate column PSPC The PSPC is described by an axial dispersion model that allows one to cover the entire range between plug flow and perfectly mixed stirred tank reactors and therefore enables the simulation of a wide
To best replicate industrial PSEC unit operations found in the nuclear reprocessing industry the geometry used in this investigation was designed using generic sizing constraints taken from Logsdail and Slater 1991 in The Handbook of Solvent Extraction which provides a range of dimensions for previously operational PSECs The dimensions of this
Pulsed sieve plate extraction columns PSECs are crucial in nuclear spent fuel reprocessing Analysing PSECs under various operating conditions is essential to their optimization and scale up A PSEC consists of a vertical cylindrical tube containing a set number of stationary horizontal perforated plates Figure 1 The two immiscible
