SIP-1111™ Refinery
MOLECULAR ASPHALTENE MANAGEMENT
Designed for the molecules that make bottom-of-barrel streams hard to use.
Deeper refining and solvent deasphalting concentrate the largest, most aromatic and heteroatom-rich molecules in the residue. Their aggregation drives brittleness and limits how much of the stream can become quality paving asphalt.
- Target the aggregate SIP-1111™ uses controlled oxirane functionality to interact with asphaltenes at asphalt-processing temperatures and stabilize them within the binder system.
- Restore compatibility The semi-epoxidized structure combines asphalt-compatible fatty segments with reactive sites selected to avoid the weak staying power of unmodified oil and the excessive multifunctionality of fully epoxidized oil.
- Preserve the grade window Formulation work evaluates both the softening needed to make difficult residue workable and the high-temperature properties needed for the finished paving grade.

FROM FORMULATION TO PAVEMENT
Shift the operating line, then prove the finished asphalt.
The refinery case study follows the decision that matters commercially: recover more high-value material, restore the resulting residue, and verify that the asphalt still meets binder and mixture performance targets.
Concentrated formulation
2% case-study dosageIn the presentation's SDA-pitch case study, a 2% SIP-1111™ formulation moved the difficult base material into the illustrated 50/70 grade window, compared with 15% mineral diluent in the reference pathway.
High-temperature performance
Grade and MSCR checkedUnaged and RTFO-aged testing in the case study shows the SIP-1111™ formulations passing the illustrated high-temperature specification while maintaining favorable MSCR rutting response.
Balanced mixture response
1.2 km field sectionA 1.2 km demonstration section paired comparable dynamic modulus with improved predicted cracking response and in-spec rut resistance.
Scale through evidence
Data · Lab · FieldSoyLei's refinery evaluation path progresses from data sharing to laboratory formulation and then to a production or field trial built around the refinery's actual streams.
Case-study results apply to the tested materials and formulations. Finished grades and dosage depend on residue chemistry, available blend stocks, processing conditions, and target specifications.
