PROBLEM TO BE SOLVED: To decrease an occupied area by enabling a more smaller size decanter to be used by a method wherein a multi-phase effluent is decanted after reaction in some different decantation zones to be arranged parallelly, and a decanter is equipped to each of the zones. SOLUTION: A multi-phase effluent exhausted from a reactor R is separated into two fractions. One side fraction is conveyed to a decantation zone A containing a single decanter via a pipe line 3, and the other side fraction is conveyed to a decantation B containing a single decanter via a pipe line 4. A heavy phase of the decantation zone A is conveyed to the reactor R via a pipe line 7, and the heavy phase of the decantation zone B is conveyed to the reactor R via a pipe line 6. A light phase of the decantation zone A is supplied to a pipe line 1 for casting a new article charging raw material into the reactor R via a pipe line 8. The light phase of the decantation zone B is discharged from an apparatus via a pipe line 5.
