1. A method of removing a metal substance in a petrochemical product, the method comprising:

supplying a petrochemical product stream to an incoming tank through a supply pipe, circulating the petrochemical product stream through an incoming tank circulation pipe, and removing a metal substance included in the petrochemical product stream using one or more first magnetic filters provided in any one or more of the supply pipe and the incoming tank circulation pipe;

transporting the petrochemical product stream to an outgoing tank through an incoming tank discharge pipe which is branched from the incoming tank circulation pipe and connected to the outgoing tank;

circulating the petrochemical product stream through an outgoing tank circulation pipe provided in the outgoing tank and removing the metal substance included in the petrochemical product stream using one or more second magnetic filters provided in the outgoing tank circulation pipe; and

transporting the petrochemical product stream to a branch pipe branched from the outgoing tank circulation pipe, wherein the branch pipe comprises one or more ion exchange resins filters to remove the metal substance.
