Manufacturing method and manufacturing system of blended hydrocarbon composition

A manufacturing system of a blended hydrocarbon composition comprising:

• a dehydrator which applies voltage to a first blended solution in which waste plastic pyrolysis oil is blended with washing water and a demulsifier to dehydrate the first blended solution;
• a hydrotreating device which hydrotreats a second blended solution in which the dehydrated first blended solution and a sulfur source are blended to manufacture refined pyrolysis oil from which impurities have been removed;
• and
• a blending device which blends the refined pyrolysis oil with a petroleum-based hydrocarbon to manufacture a blended hydrocarbon composition.

A method for manufacturing a blended hydrocarbon composition, the method comprising:

• forming a first blended solution including a waste plastic pyrolysis oil, washing water, and a demulsifier;
• applying voltage to the first blended solution to form a dehydrated first blended solution;
• adding a sulfur source to the dehydrated first blended solution to form a second blended solution;
• hydrotreating the second blended solution to produce a refined pyrolysis oil;
• and
• blending the refined pyrolysis oil with a petroleum-based hydrocarbon to manufacture a blended hydrocarbon composition,
• wherein the petroleum-based hydrocarbon includes at least one selected from the group consisting of gasoline, kerosene, aviation fuel, diesel, lube base oil, marine fuel oil, asphalt, and wax.
