Success Stories



Heysham 2 power station differs from other stations where trials have been held by virtue of its geographic location in relation to our base in South Yorkshire and also by the fact that it is Nuclear powered and therefore subject to a more rigorous security policy. This has meant that we are limited to results from samples taken by the station staff and the sampling regime is not quite as comprehensive as we would normally do when we are totally dedicated to this task. However the simple truth of the matter is the trial unit was installed on 9th July 2009 and a sample taken from inlet side of unit, this sample although of good colour was certainly cloudy. A sample was then taken on the 10th July and by this time the oil was clear and bright. A sample was taken PM on the 11th as turbine was being run up to load and the subsequent analysis of this was 647ppm. On Monday the 13th a sample was taken and analysed the resultant contamination level was some 39ppm. Although some 40 hours had elapsed between samples the results are still superb and show levels of oil purity that Heysham 2 has never experienced before.


The trial at Eggborough was conducted on unit 3 500mw main turbine. At commencement of trial the information we had was the system had a water content of some 160 ppm unfortunately this figure was from samples taken on the delivery side of circulating pump and bore no relationship to levels of water in the reservoir which on analysis measured some 17,900 ppm. Needless to say that in a matter of three days the levels within the whole system had been reduced to somewhere in the region of 100ppm. Over the period of ten days where the turbine was operating in a two shifting mode in excess of some 3,000 litres of water was removed.
