 The
world became to pay more attention on the safety of Base-oil since OSHA Hazard
Communication (1985) and EU PCA standard (1995).
In order to avoid the Carcinogenic Risk of Base-oil, High-pressure, High-temperature
Hydro-treating is proved to be the best. Especially in case of Naphthenic Base-oil,
all of European and American Refineries have changed their refining process to
High-pressure, High-temperature Hydro-treating.
No more Solvent Refining unaccompanied by Hydro-finishing and no more Acid /Clay
treatment.
Hydro-treating Process differs so much depending upon the purpose.
Our Hydro-treating Process, which was selected after many years of research and
tests for finding Optimal Pressure, Optimal Temperature, LHSV, Catalyst etc.,
enable us to break hazardous PCA selectively and to preserve CN and non-hazardous
CA of 1 and 2 aromatic rings.
As a result, we can supply SNH series Naphthenic Base-oil which is not losing
very good Naphthenic characteristics (solubility etc.), and SNH series pass
both OSHA and PCA standard at the same time.
Our Vacuum Distillation Plant has also special know-how to neutralize Naphthenic
Acid during the distillation process so that we can have non-acidulous base-oil
feed which goes to Hydro-treating plant. If you feed Acidulous base oil
to Hydro-treating plant, catalyst life will become extremely short due to Acid
Damage.

SNH series will in many fields, replace the high-grade MVI(Medium Viscosity
Index), which is severely Furfural Extracted, in spite of the former belief of
MVI's advantages.
- Refrigerating oils
- Process oils for Rubber and Plastics

SNH series will omit the Acid/Clay finishing process for many applications.
- Transformer oils and other Insulating oils
|

SNH series are really recommended for those applications which deeply cares
"Safety of workers and consumers" and "Environmental cleanness"
- Ink oil (Printing Ink carrier)
- Base material for Grease
- Base-oils for Metal working fluid (Cutting oil, Deformation processing
oil etc.)
- Insecticide/Agricultual-chemical spraying emulsion)
- Process oils for Rubber and Plastics
- Process oils for Binding Agents and Adhesive tapes
- Additive for asphlt
