HIGH EFFICIENCY FILTRATION OF A COMBINED CYCLE GAS TURBINE IN CATALONIA

At the end of October, Sicelub Ibérico, our company in Spain, carried out an intervention in an important Combined Cycle Power Plant in Catalonia. We intervened on a gas turbine.

We drained the lubricating oil from the main tank, approximately 23,000 liters, into an external tank, where a high efficiency filtration is carried out, while a mechanical cleaning of the tank is carried out, considered a Confined Space. It is important to indicate that during the cleaning we found tools inside the tank (see photo).

Once the cleaning of the tank was completed, and having the approval of the owner, the oil is loaded again under filtration; until reaching the appropriate ISO cleaning code.

A 320 lt/min filtration system was used with 34” long filter elements and β1›1000 (filtration efficiency of 99.9% for particles larger than 1 micron).

It can be seen in the ISO 4406 Code evolution curve how the lubricant cleanliness level was improved from ISO 19/18/14 to ISO 14/13/11. This means that the lubricant oil is delivered with 30 times less particle content. This feature provides a greater probability of correct operation of the turbine, and a longer expected life of the lubricant.

It is also very important to highlight that, due to the Meteorological Alert, we had to change the return route of our technicians, to avoid any risk.

We would like to thank our clients, our suppliers, and our staff for their trust in us, in providing a quality, safe, and environmentally friendly service.

08 – Lubricant Functions. Particle Removal.

In this video, we are going to delve into another of the lubricant’s functions and how it is improved by moving from oil level to oil mist lubrication.

We analyze in detail the function of removing particles. When we have an oil bath, it is easy to notice that any dirt or wear particles present will remain suspended in the oil bath, and there is no possibility of them being eliminated. The presence of these particles will cause abrasive wear of the bearings. In the case of oil mist lubrication, since there is a permanent flow of oil mist entering and leaving the system, it is easy to notice that any dirt or wear particles present will be expelled outside the tribological contact zone. A common example is to compare the situation of taking a daily immersion bath, always using the same water, which periodically becomes dirty; with the situation of changing the above for a fresh shower with clean water, a situation that is undoubtedly much more effective and common.

The process that would be quite strange for a daily personal hygiene situation; It is widely accepted in the industry when it comes to bearing lubrication. Undoubtedly, an opportunity for significant improvement.

07 – Functions of lubricant. Lubrication

In this video, we will delve into one of the functions of lubricant and how it is improved by moving from oil level to oil mist lubrication. Lubricating oil has different functions, among the most important we highlight lubricating, cleaning or removing particles, cooling, and protecting against corrosion.

We analyze the lubricating function in detail. While in the oil bath or level, this function is only fulfilled in a pump in operation; when the oil mist is applied, lubrication is achieved both in pumps in operation, as well as in pumps on standby. In an oil bath, we depend on the ring or disc to deliver lubricant to all the internal parts of the pump. In the oil mist, all the internal parts of the pump will be always impregnated with oil, optimizing the lubricating function.
