Oily waste treatment

Oily waste at power plants comprises waste oil from fuel and lube processes, but also oily water, which is usually further contaminated by chemicals and particles. Separating the water, oil and solids protects the environment and can reclaim fuel losses.

Drying up the oily waste streams

The majority of oily waste is water. There is water contaminated by oil, which must be cleaned to established limits before it can be discharged into the environment. But even the waste oil from separators and filters is almost 50% water.

Centrifugal separation is the only way to deal effectively with all of this oily waste. Using Alfa Laval PureDry, every drop of liquid can be removed from the waste oil. The separated water, like all other oily water, can then be cleaned with Alfa Laval PureBilge down to an oil content of less than 5 ppm.

Saving fuel and money

Water isn’t the only thing PureDry can extract from waste oil. When separate waste tanks are used for fuel and lube oil in diesel installations, it can recover quality oil for reuse as fuel – typically as much as 1-2% of the original volume consumed.

Money is also saved by the 99% reduction in waste oil volume. With the water and oil removed, only super-dry solids are left. This allows smaller waste oil tanks to be used, which saves both space and installation cost.
