Embodiment 1
[0012] Attached below figure 1 Illustrates a semi-continuous extraction or stripping process for processing heat-sensitive, easily emulsified organic phases:
[0013] First, the extractant 1 for extraction and the aqueous solution 2 to be treated, or the loaded organic phase 1 and stripping agent 2 for stripping are respectively metered and then continuously transported to the preheater A and heated up to the temperature required by the process Finally, the high-temperature oil-water mixture 3 is used for extraction or stripping;
[0014] Secondly, open the stirring system of the extraction or stripping reactor C1 inlet automatic adjustment valve B1 and C1-C3, close the C1 outlet automatic adjustment valve D1, close the C2, C3 import and export automatic adjustment valve B2, B3, D2, D3, let 3 Enter C1, and perform extraction or stripping in C1;
[0015] After a certain period of time, open the C2 inlet automatic adjustment valve B2, close the C1 inlet automatic adjustment va...
