Abstract

A base load power station continuously produces liquid oxygen and liquid nitrogen. During peak power demand, liquid nitrogen is vaporised by waste heat and drives an expansion turbine. The energy recovery is about 80 %. The liquid nitrogen can also be used as cooling gas for a gas turbine and replace the compressed cooling air. In this way, the energy balance of the gas turbine is improved. With suitable siting of the plant, the expanded nitrogen can be used as synthesis gas. The oxygen arising is utilised in the known manner (oxygen steelworks) or used for the combustion of fossil fuels. As a result, the flue gas volume is considerably reduced and the absorption of the sulphurous acid is facilitated.
