Abstract: The present invention relates to a fluid collector for use in a packing column, comprising at least one element for collecting (5) the fluid (element A) (5, 6) flowing out of the packing bed and at least one draw from the column (10), wherein all elements (5, 6) are at a distance from (7) the column wall (3) and optionally a separating wall, or at least one capture device is mounted above or in the fluid collector (5), so that fluid flowing downward on the wall in the collection direction is collected and passes by the elements A (5, 6). The invention further relates to a packing column for separating substance mixtures, comprising at least one fluid collector and draw according to the invention. The invention further relates to a method for separating one or more components from a substance mixture in at least one packing column according to the invention. The method is used particularly in order to obtain a highly pure product from a side draw or sump draw by means of the fluid collector according to the invention.

Abstract: The invention relates to an integrated method for producing trioxane from formaldehyde. According to said method, a flow A1 containing water and formaldehyde and a return flow B2 consisting essentially of water and formaldehyde are introduced into a trioxane synthesis reactor in which the formaldehyde is converted into trioxane, forming a product flow A2 containing trioxane, water and formaldehyde; the flow A2 is introduced into a first distillation column and distilled at a pressure of between 0.1 and 2.5 bar, forming a trioxane-enriched flow B1 and the flow B2 consisting essentially of water and formaldehyde; the flow B1 and a return flow D1 containing trioxane, water and formaldehyde are introduced into a second distillation column and distilled at a pressure of between 0.2 and 17.5 bar, forming a product flow C2 consisting essentially of trioxane and a flow C1 containing trioxane, water and formaldehyde; and the flow C1 is introduced into a third distillation column and distilled at a pressure of between 0.1 and 2.5 bar, forming the return flow D1 containing trioxane, water and formaldehyde and a flow D2 consisting essentially of water and formaldehyde.
