TNK Syngas Compressor Oils


The TNK Syngas oils are designed for circulating lubrication systems of the centrifugal processing compressors used in the production of ammonia, sulphuric acid, adipinic acid, etc. where the oil must have higher anti-oxidative properties, prolonged service life and lowered bent for precipitation.
The TNK Syngas oils are highly hydro-processed mineral-based oils with the high performance imported package of the additives which improve the anti-oxidative, anti-corrosive and demulsifying properties of the oils.
In the compressor lubrication systems the oils are used to lubricate bearings and couplings of the hydraulic control systems and sealing systems for compressors.


TNK Syngas series have following advantages:
 Perfect anti-oxidative properties allow minimizing deposit formation in lubrication systems
 Prolonged service life, compared to conventional oils like Tp-22B
 Prevent corrosion, mitigate the adverse effects resulting from water presence in the system
 Rapid water separation prevents emulgation
 Comprise the imported package of additives


The TNK Syngas 32 and 46 oils conform to ISO VG 32 and 46 viscosity class, respectively. The anti-oxidative properties of the oils have been tested by the VNIINp research institute in the presence of ammonia and approved for use in the turbocompressors including 103J N 105J designed and supplied by TEC for the ammonia production facilities.
