![]() The method disclosed by the invention can be applied to the industrial production on the recovery of the hexane from the production of the high-density polyethylene. Due to adoption of the technical scheme, the problems are well solved. The method comprises the following steps: (a) feeding hexane flow 5 into a catalyst preparation tank 1, and mixing the hexane flow 5 with a catalyst, wherein a prepared catalyst 9 is obtained at the bottom of the catalyst preparation tank 1, and a hexane exhaust 6 is obtained on the top of the catalyst preparation tank 1 (b) feeding the hexane exhaust 6 into a suction tank 3 of a compressor to obtain a hexane exhaust 10 with pressure being stabilized and (c) feeding the hexane exhaust 10 into a gas compressor 4, increasing the pressure to obtain a high-pressure hexane exhaust 11, and feeding the high-pressure hexane exhaust 11 into a subsequent drying gas system. The invention relates to a method for recovering hexane from the production of high-density polyethylene, and mainly aiming to solve the problems on the loss of the hexane and the pollution of the discharged hexane to environment in the prior art.
