昌达制氧设计制造的全液体空分装置可同时生产液氧、液氮、液氩产品。根据装置产能大小不同，具备多种流程组织形式及设备配置方案。在标准设计工况下，小型装置循环氮压机采用活塞式，能耗大约 1.4kW・h/kgLO；大型装置循环氮压机采用离心式，能耗约 1.1kW・h/kgLO。

The full-liquid air separation units designed and manufactured by Changda Oxygen Generation can simultaneously produce liquid oxygen, liquid nitrogen and liquid argon.
Multiple process layouts and equipment configuration schemes are available for different unit capacities.
Under standard design conditions, small units adopt piston circulating nitrogen compressors with energy consumption of around 1.4 kW·h/kg LO; large units adopt centrifugal circulating nitrogen compressors with energy consumption of about 1.1 kW·h/kg LO.
