For independent refineries with real refining lines processing imported crude oil, focused on lowering residual phosphorus, filtration pressure drop and bleaching-earth consumption — a more cost-effective, stable refining combination.
Typical benchmarks: W. R. Grace TRISYL® series (dephosphorization / desoaping / filtration), PQ Sorbsil® oil pretreatment silica gel series, Fuji Silysia refining and adsorption silica gel series.
We don't replicate brand premiums. We enter through niche applications, second-source / backup supply and multiple grades, and differentiate with profile screening, problem diagnosis and sample conversion.
| Test dimension | What to watch | What it tells the customer |
|---|---|---|
| Dephosphorization | Whether residual phosphorus is lowered | Judges refining effect |
| Soap residue | Whether desoaping quality improves | Judges product purity |
| Filtration pressure drop | Whether the filtration burden is reduced | Judges production efficiency |
| Bleaching-earth use | Whether earth use and overall cost fall | Judges economics |
