In a butene extraction unit using acetonitrile for extraction and distillation, is pentane located at the top or the bottom of the tower?

As the title says! Will the product from the extractive distillation tower and the product from the desorption tower contain acetonitrile?
Really, no one knows? Are there any colleagues who have never been in contact with butadiene extraction units?
There must be some; it’s impossible to do without acetonitrile to achieve such a high separation rate
