Air separation compressors are widely used in the sectors of air separation plants of large chemical industry and coal chemical industry. Shaangu air separation compressor train serves for the air separation plants from 20,000 Nm³/h to 150,000 Nm³/h. The air separation compressor train are usually design as one air compressor and one compression booster for internal compression process of ASP, while there is only one air compressor designed for external compression process. Shaangu air compressor trains usually use EIZ/EIZT series compressors. Definition of the model code are following: Take “EIZ90-4/EIZT125-3” as an example: EIZ/EIZT – The series code, refers to centrifugal compressor with integrated built- intercooler 90/125 – Size of the compressor, represents the nominal diameter of first stage of impeller, unit: cm 4/3 — Number of impeller Characteristics of EIZ/EIZT Compressors: Serialization design and efficient three-dimensional impellers. Built-in intercooler (s) reduces length and resistance of gas flowing path to realize isothermal and high-efficient operation The compact built-in intercooler (s) has excellent noise reduction function.. Inlet guide vanes ensures wide operation range (from 75% to 105% of variable operation condition) to effectively reduce energy consumption。 Built-in spraying system realizes on-line cleaning of impellers and cooler tubes to ensure long-term stable operation and minimize downtime operation. Shaangu booster compressor includes EZ/EBZ and EG series models. EZ series compressor is horizontal split type structure with the external interstage cooler.
