Analysis on line for the Continuous measurement of the presence of remaining in a Lower Liquid liquid extraction in the extraction Tower operation

摘要

A method for operating a claim number extraction Tower under conditions of extraction of solbente buy - stages: (a) introducing a feed to be separated in compoComponents at one end of a Tower of ex - Traction has a feed end and a Second End.The End opposite to that on which it introduces power which are do the Meteorological devices with temperature; (b) introduce a selective solvent extraction in an OPUIt is introduced that in which EC Food; (c) to maintain a temperature gradient in the height of the Tower so that the temperature in the tower in which IntrodThe Solvent is equal to or greater than the temperature at the other end of the Tower,Being called Temperature At the end opposite the end of the introduction the background temperature of Solvent Recovery Tower; (d) a refined output refines - OJ L at the end ofThe Point opposite the tower in which the food was introduced; (e) to recover an extract through an Exit extract in the Tower at the opposite point which recovers the refiSwimming; (f) to extract a sample of the output of extract; (g) The extract Sample through a filter to remove Solid Particles Catcher; (H) the sample of extracTo filter through a recirculating Loop with recirculating Pump Devices, devices of Heating - coolingPAIRED DEVICES, temperature Sensors of the temperature sensortes devices equipped in the Tower and Turbidity Analyser; (i) placing the sample filtered extract reRepeated heating Cooling circulating stages Centered around the temperature of Tower Bottoms,Such a warming and - friamientos being at temperatures of 5 to 100 gra - two farengei (- 15 to 37.7 degrees Celsius) above or below the base temperature of the Tower; (j) the sample during the stages repetiti - heating and Cooling through the device anAlizador Turbidity which analyzes the presence of a second phase in the sample extract.Firing the Turbidity Analyzer detects a Signal if a second phase when the sample temperature is above the temperature of the Tower Bottoms,Thus indicating the presence of remnant in the lower ex - Tract; (k) to adjust the operating conditions of the Tower to reduce or eliminate the remnant infe - rior; (L) to open the Control ValveL to wash the sample Loop; (m) repeat Steps (f) to (m).
