Compressor К1290-121-1 is designed to compress air in the process cycle of ammonia production according to GIAP technology.
A double-effect, four-section compressor. The low-pressure housing includes two sections 3 stages in each. The high-pressure housing includes section 3 with 2 stages and section 4 with 4 stages. The sections are located one after the other. Compressed air after each section is cooled in an intermediary air gas cooler. All stages are designed with vaned diffusers. The drive is through a steam turbine. The rotor of the low-pressure housing is rotated directly by the steam turbine, and the rotor of the high-pressure housing through a multiplier with the gear ratio i=2.8.
