    Abstract: A process for rectificatively separating at least one (meth)acrylic monomer-containing fluid by feeding the fluid into a rectification column containing at least one sieve tray without a runoff segment, wherein an elementary cell is obtained from a number of centers of passages in a sieve tray, and the cell shifts regularly and repeatedly along its edges, the lengths of two shifting vectors being the lengths of the edges of the cell along which the shifting is effected; an arrangement of the centers is such that the positions of an ideal center and a real center are separated by ≦1% of half of the sum of the lengths of the two shifting vectors; and an arrangement of the passages is such that the sum of non-overlapping surface areas of an ideal passage with a real passage and vice versa is ≦1% of the surface area of the ideal passage.
