Method & Evidence

AimTo design and operate a pilot-scale distillation column for the recovery of value-added products from tire pyrolysis oil.
MethodExperimental and Simulation-based Design
ProcedureA pilot-scale packed distillation column was designed using engineering heuristics, simulation data (SimDist), and process modeling software (Aspen Hysys). The column was then commissioned and operated with tire pyrolysis oil from a pilot pyrolysis plant. Multiple distillation stages were performed to separate the oil into different fractions based on chemical composition.

Strengths & Limitations

Strengths

  • +Combines simulation and experimental validation.
  • +Addresses a significant waste stream (end-of-life tires).
  • +Identifies multiple value-added products.

Limitations

The pilot scale might not perfectly represent full industrial scale. The energy cost of distillation needs to be considered for economic viability.

Reliability & validity

The study's reliability is supported by long-term experimental campaigns and validation using simulation data. Validity is established by the successful separation into known valuable chemical fractions.

Paragraph starter

The recovery of valuable petrochemical feedstocks from tire pyrolysis oil, as demonstrated by Martínez et al. (2023), highlights the potential for waste valorization. Their pilot-scale distillation process successfully separated the oil into fractions suitable for carbon black production, as well as BTEX compounds and limonene, which are crucial raw materials for polymer and petrochemical industries. This research provides a strong precedent for incorporating waste stream upcycling into sustainable design strategies.
