THERMAL SEPARATING METHOD

Thermal separation method between at least a gas ascending in the separating column and at least a liquid containing at least a (meth)acrylic-monomer descending in the separating column, accomplished in a separation effective installation containing separating columns, where at least a part of separation-effective installation is at least a series of at least two structurally identical cross-flow mass transfer trays, which comprise at least one outlet shaft (1), through which liquid descends through the respective cross-flow mass transfer trays, is claimed. Thermal separation method between at least a gas ascending in the separating column and at least a liquid containing at least a (meth)acrylic-monomer descending in the separating column, accomplished in a separation effective installation containing separating columns, where at least a part of separation-effective installation is at least a series of at least two structurally identical cross-flow mass transfer trays, which comprise at least one outlet shaft (1), through which liquid descends through the respective cross-flow mass transfer trays, is claimed. The cross-flow mass transfer trays are arranged one above the other within the at least one series in the separating column in such a manner that: the two cross-flow mass transfer trays are rotated from top to bottom in the separating column around 180[deg] around the column longitudinal axis, where their outlet shafts are present on opposing sides of the separating column; the at least one outlet shaft of the two successive upper consecutive cross-flow mass transfer trays form at least a supply shaft for the cross-flow mass transfer trays located under it, through which the liquid descends from upper cross-flow mass transfer trays as at least an inlet on the cross-flow mass transfer trays located under it; the liquid descending through the at least an inlet shaft from upper to lower cross-flow mass transfer trays, over which (entire) lower cross-flow mass transfer trays are viewed, flows crosswise from the at least an inlet on the lower cross-flow mass transfer trays to the at least one outlet shaft of the lower cross-flow mass transfer trays; and passage openings (2) find between the at least an inlet on the lower cross-flow mass transfer trays and the at least one outlet shaft of the lower cross-flow mass transfer trays, through which the at least one gas ascends through the lower cross-flow mass transfer trays. At least within one of the at least
