1.0 Overview Triveni have installed a 5 and a 10 MW turbine at the site in Belfast. Following the flushing of the turbine hydraulic systems, Kleenoil were tasked with reclaiming the oil over a 4 day period to a cleanliness level of NAS6.

The filtration rigs used to complete this task are detailed below: -

Kleenoil MS4

Filter vessels 4 Pump

240v, Roto MM 550 – 750 (l/hr)

Flowrate

Kleenoil MS6

Filter vessels 6 Pump

240v, Roto ML 1200-1500 (l/hr)

Flowrate

3.0 Results

On returning all oil samples were set for analysis. The full analysis for 5MW, 10MW and new oil can be found in appendix C, D and E respectively.

3.1 5MW Turbine

The results from the 5MW turbine are shown in the table below. The chronology is from right to left i.e. 1 st sample is on the left and last sample, taken from the tank, is on the right.

From the above, the following can be said: -

 The Kleenoil unit polished the oil from 22/20/14 down to 19/17/14 for the first 12 hours.  Following the stirring of the tank a significant amount of contamination was introduced to the system, resulting in the result increasing to 23/22/18.  Following a further 12 hours of operation the final sample from the tanks gave a result of 19/17/13, which is a NAS 5.  While on site the particle counter was fitted to the rig. This gave a reading of NAS 5 also.

Conclusions

 Kleenoil polished the oil to NAS 5, which exceeds the NAS 6 requirement.

3.2 10MW Turbine

The results from the samples taken from the 10MW turbine are shown in the table below.

From the above, the following can be said: -

 The Kleenoil unit polished the oil from 22/20/15 down to 21/18/13 (final tank sample) over the 4 day period.  The reading of 21/18/13 is equivalent to a NAS 6.  While on site the particle counter was fitted to the rig. This gave a reading of NAS 6. This confirms that the particle counter was operating correctly.

Conclusions

 Kleenoil polished the oil to NAS 6, which meets the customers requirements of NAS 6.
