Salzbergen thermal waste treatment plant (TAS)
As per 1 January 2003, the refinery operator H&R ChemPharm transferred the complete energy supply for the Salzbergen location to SRS EcoTherm GmbH, in which RWE Generation SE holds 90% and H&R itself 10% of the shares.
In operation since September 2004
At the heart of the Salzbergen industrial concept are the construction and operation of the thermal waste treatment plant, TAS for short. After a construction period of some 24 months, TAS has now been generating 360,000 tons of steam from an annual 120,000 tons of municipal waste since September 2004. Travelling through an 800-m-long pipeline, the steam reaches the industrial power plant – likewise passed to SRS EcoTherm – where it is initially used to produce electricity and then further utilized as process steam.
Constantly under full load
Two of a total of four heavy-oil-fired boilers of the industrial power plant that had hitherto been in charge of generating steam were decommissioned at the end of 2005. Since the TAS is constantly operating under full load, it delivers some two-thirds of the steam required by the location, while peak demand is covered by the two remaining oil-fired boilers.
Energy concept with measurable merits
For H&R ChemPharm, for the region and for the environment, the new energy concept brings measurable merits: the refinery can cut its annual energy-supply costs on the basis of current oil prices by some 40%. The fixed prices for steam deliveries over 20 years agreed with SRS EcoTherm also make production independent of price fluctuations on the oil market, thus offering a dependable calculation basis.
Emissions minimized thanks to modern technology
Emsland county has secured for itself – likewise for 20 years – low-cost removal of 70,000 tons of municipal waste annually. The remaining 50,000 tons is contributed by Norddeutsche Waste Contracting GmbH. The emissions produced at the location from energy generation are reduced to a minimum thanks to the deployment of ultra-modern combustion and flue-gas scrubbing technology: by 40% for dust, by 38% for nitric oxide, and by 77% for sulphur dioxide.
