The importance of oil mist separators
Oil mist can lead to contamination, increased maintenance requirements, and safety risks in industrial facilities. An oil mist separator provides effective filtration by removing oil particles from the air and reducing emissions. This not only creates a cleaner and safer working environment, but also lowers operating costs and extends the service life of lubricating oil systems. Learn more about how an oil mist separator can contribute to more sustainable and safe operations.
What is an oil mist separator?
An oil mist separator, also known as an oil mist eliminator or demister, is a specialised filtration system used in facilities where power generating engines and turbines are in operation, such as power plants and refineries. During operation, bearings are lubricated with oil to ensure smooth and reliable performance. However, this process generates oil mist which, without adequate filtration, can be released into the atmosphere and cause oil deposits and contamination within the facility.
Did you know?
Oil mist separators can be supplied in various designs tailored to specific requirements, including ATEX approved models for hazardous environments, stainless steel units for corrosive conditions, and systems with redundant designs for critical applications.
Oil mist separators from FRANKE Filter offer maintenance free operation for up to 30,000 hours, corresponding to approximately 2–5 years of trouble free use. This is achieved through advanced micro filter cartridges and high manufacturing quality.
Why is an oil mist separator important?
The use of oil mist separators offers several benefits for the environment, operational efficiency, and employee safety:
- Environmental protection: Unfiltered oil mist can contribute to air pollution and oil deposits in the working environment. An oil mist separator captures and recirculates the oil, reducing emissions and environmental impact.
- Cost savings: By preventing oil losses, the need for oil top ups is reduced, resulting in long term cost savings.
- Cleaner and safer working environment: Oil mist can create oily residues on surfaces, making floors slippery and increasing the risk of accidents. A separator improves workplace safety by removing oil mist from the air.
- Improved operational reliability: Oil mist can cause overpressure in lubricating oil systems, potentially leading to leaks and mechanical failures. By maintaining a constant vacuum in the lubricating oil tank, the separator ensures stable and reliable operation.
How does an oil mist separator work?
An oil mist separator operates using specially developed micro filter cartridges that capture oil particles from the mist. This provides a filtration efficiency of up to 99.99% for particles as small as 0.1 µm. The collected oil particles are returned to the lubrication system, contributing to extended oil service life and reduced maintenance requirements.
Applications for oil mist separators
Oil mist separators are used across a wide range of industrial and maritime environments, including:
Power plants – Turbines and generators
Oil and gas industry – Refining and process facilities
Marine & Offshore – Ship engines and drilling rigs
Industrial production facilities – Lubrication systems for large machinery
