True or False: When distilling in a vacuum tower, the valve between the main tower and the stripping tower should be closed, so that the main tower and the stripping tower operate separately. × Correct**: When steaming the tower, the valve between the main tower and the stripping tower should be opened, so that both the main tower and the stripping tower are steamed together.
