Ethylene Tar
Steam Cracker Tar
Heavy aromatic residue from steam crackers, also known as pyrolysis fuel oil. Supplied in bulk cargoes as carbon black feedstock and as a blending component for industrial fuel oil.
Request a Quotation View SpecificationsProduct Overview
Ethylene tar is the heaviest liquid by-product of steam cracking, the process that turns naphtha or gas oil into ethylene and propylene. It is very rich in aromatic carbon, which makes it valuable for carbon black and fuel blending.
High Aromaticity
A high BMCI value shows the strong aromatic content that carbon black producers need.
Low Sulphur
Sulphur content is usually low because steam crackers run on low sulphur feedstock.
Dense and Viscous
Heavy liquid with density above water. Stored and pumped hot in heated tanks.
Inspected Cargo
Quality and quantity verified by an independent inspector at loading and discharge.
Typical Specifications
Indicative commercial ranges for comparison. The final specification is agreed in the contract and confirmed by the independent inspector's report.
| Parameter | Typical value | Test method |
|---|---|---|
| Density @ 15°C (kg/m³) | 1,020 – 1,100 | ASTM D4052 / ISO 3675 |
| Viscosity @ 100°C (mm²/s) | 20 – 100 | ASTM D445 |
| BMCI (aromaticity index) | min 120 | calculated from density and distillation |
| Sulphur (% m/m) | max 1.0 | ASTM D4294 |
| Flash point (°C) | min 65 | ASTM D93 |
| Water (% v/v) | max 1.0 | ASTM D95 |
| Ash (% m/m) | max 0.05 | ASTM D482 |
| Micro carbon residue (% m/m) | per contract | ASTM D4530 |
| Pour point (°C) | per contract | ASTM D97 |
Values are indicative and change from plant to plant. Ethylene tar is traded on the seller's own specification. Cargo quality is established by independent inspection at the load port.
Applications
Used wherever a heavy aromatic oil is needed.
