How is sampling carried out in a distillation tower?

If you carry out extraction in the tower, the top and bottom of the tower function as they do in a regular tower: what needs to be recycled is recycled, and what needs to be extracted is extracted. Depending on the composition of the extracted liquid, appropriate methods can be applied; if no suitable method exists, the liquid can be tried to be separated before further use or disposed of as hazardous waste. As for the various parameters, they should be adjusted based on the results of the extraction process. This is essentially equivalent to combining two distillation towers into one. . . The main things to pay attention to are the quality of the product obtained and the energy consumption. The operating procedures are the same as those for ordinary towers; at the beginning, full reflux is used, and once stability is achieved, feeding begins. If the product does not meet the standards, it is sent back to the raw material tank; if it meets the standards, it is transferred to the product storage tank
