    摘要: Provided are an apparatus and a method for manufacturing high-pressure method low-density polyethylene, the apparatus and the method having excellent characteristics that the amount of smoke generated during processing of a polyethylene to be obtained is small, and the number of fish eyes contained in a film formed from the polyethylene is small. An apparatus for manufacturing high pressure method polyethylene includes: an ethylene supply line that is a line branched from a high pressure recycle ethylene line and connected to a recycle ethylene holding drum for decompressing high pressure recycle ethylene from the high pressure recycle ethylene line and supplying the decompressed recycle ethylene to the recycle ethylene holding drum; and the recycle ethylene holding drum that is a drum for holding the decompressed recycle ethylene through the ethylene supply line.
