Abstract
There is presented a process for recovering energy from blast furnace top gas in a blast furnace plant with top gas recovery turbine system, wherein the blast furnace plant comprises at least one cold blast compressor (12) associated with at least one blast air preheater (14), and wherein a pressurized top gas stream released by the blast furnace (10) is passed through a top gas cleaning unit (24) and fed to an expansion turbine (20) coupled to a load (34). According to the process, heat is extracted from the pressurized cold blast and the extracted heat is transferred, at least in part, to the cleaned top gas upstream of the expansion turbine.
