Abstract

This invention provides a 2-octanol recovery device for sebacic acid production, comprising a cracking reaction assembly, a high-level water tank, and a condensation recovery assembly. The cracking reaction assembly includes a cracking reactor and a feed tank. A gas emission pipe is located at the top of the cracking reactor, and the bottom of the reactor is connected to the feed tank via a discharge port. The condensation recovery assembly includes a condenser, a tail gas absorption tower, and a 2-octanol separation tank. A condensate inlet is located on one side of the condenser, and a water outlet is located at the top of the condenser. The water outlet is connected to the feed tank via a pipeline and also to a decolorization workshop via a pipeline. A water inlet and a condensate outlet are located at the bottom of the condenser. The water inlet is connected to the high-level water tank via a pipeline, and the condensate outlet is connected to the 2-octanol separation tank via a pipeline. This invention not only effectively recovers 2-octanol from high-temperature gas through the condenser but also converts the heat energy in the high-temperature gas into hot water for use in the next stage of production, thus achieving energy saving and consumption reduction.
