Abstract: The invention relates to a method for obtaining cyclododecatriene (CDT) from a solution containing CDT and high-boiling components such as a deactivated catalyst and polymers. Said solution is supplied to a preheater and heated, and is then relaxed over a downstream pressure maintaining device, and the two-phase mixture obtained is supplied to a spiral tube evaporator where the CDT content of the liquid phase is reduced by partial evaporation and a gaseous product flow with an increased CDT concentration is derived.

Abstract: What is proposed is a method for safely preventing backflowing in the conveying of a fluid under pressure through a feed line (1) in which a blocking device (2) with a differential pressure circuit is disposed, in a container (3) that is under pressure and that contains the fluid to be conveyed and/or another fluid, characterized in that a pressure accumulator (4) is disposed in the feed line (1) upstream of the blocking device (2) in the direction of flow, said pressure accumulator being filled with an inert gas in direct contact with the fluid to be conveyed up to a specified level and above the fluid level, wherein the inert gas in the pressure accumulator (4) is provided at a pressure that is higher compared to the container to be filled (3) and at an amount that is such that when the pressure in the feed line (1) drops, the inert gas guarantees a positive differential pressure in the feed line (1) to the container (3) for a duration that is at least as long as the reaction time of the blocking device (2), and that the blocking device (2) comprises a drain line (6) with a drain fitting (7).
