AUTOMATIC LUBRICANT OIL BLENDING PLANTS
Lubricant Oil Blending Plant consists of:
- Additive Weighing and Mixing
- Base oil stock Weighing and Blending
- Filling Of The Finished Lube Oils Into Containers Of Various Sizes
Lubricant oil blending and additive mixing is a fully automatic batch process which is performed within multiple parallel lines, each consisting of one additive weighing and mixing vessel and blender. Lube Oil Blending Plants are designed to achieve optimal efficiency and precision in this process.
Basic feeds to the blending process are the base lube oil stocks. The blending procedure follows the prescribed formula for each product. Additives are mixed according to the precise weight prescription in order to achieve the required properties.
Lube oil blending of base oil stock and additives takes place in specially designed agitated blenders within the Lube Oil Blending Plants.
Finished lubricant oil is transferred in dedicated storage tanks and from there it’s transferred to the barrels, canisters and bottles filling.
Standard plant sizes:
- 50 MTD / 13,500 GPD
- 100 MTD / 26,000 GPD
- 150 MTD / 40,000 GPD
