13- 13- SYSTEM FOR MANUFACTURING 13-BUTADIENE RECYCLING WASTE WATER AND METHOD FOR MANUFACTURING 13-BUTADIENE USING THE SAME

摘要

One embodiment of the present invention relates to a mixing unit for mixing a raw material containing a butene mixture, air, and steam to produce a reaction mixture; A reaction unit comprising a plurality of mutually spaced catalyst fixation layers and converting the reaction mixture into an oxidative dehydrogenation reaction to form a first product; An oxygen supply unit for supplying oxygen between the plurality of catalyst fixation layers; A cooling unit for cooling the first product and separating the second product into wastewater; A circulation unit circulating the wastewater to the mixing unit; And a separation unit for separating 1,3-butadiene from the second product. The present invention also provides a process for producing 1,3-butadiene using the 1,3-butadiene.
