Gas Turbines – A System Summary

What applies to power stations with diesel engines also has top priority for power stations driven by gas turbines: absolute reliability and safety. Gas turbines are operated using diesel, crude or heavy fuel oils – different fuels which have to be subjected to the appropriate treatment to suit their use.

 

GEA Westfalia Separator systems are used in a wide variety of process stages to achieve this. The modules in question result in a complete solution which performs all tasks reliably, whether dewatering fuels or reducing water-soluble salts or separating abrasive solids.

 

On its way from the refinery to the power station, the oil is contaminated with e. g. salt water, dust and solid particles. The most dangerous salts are sodium and potassium. These salts can lead to corrosion of the turbine blades and it is therefore essential that they be removed from the oils before use. GEA Westfalia Separator developed special treatment units for this purpose as well as for dewatering the oil and removing abrasive particles.

 

Treatment of diesel, crude and heavy fuel oils is complemented by other modules ranging from unloading the oil to special filtering and additive metering stations. The continuous treatment of sludge and waste water simultaneously solves the problem of disposal. It makes sense to round off the whole system with lube oil treatment.
