摘　　要：介绍了现阶段采用空气分离方法制备氮气和氧气的工艺。在船舶上安装空分装置,以舱室空气为原料,现场制备是解决船舶用氮气和氧气的有效方法。空分法主要有4种工艺:燃烧法、变压吸附法、膜分离法与深冷法。分析比较了4种工艺的原理、实施流程、特点及船舶适应性,提出了当前须解决的技术难点。在船舶设计过程中,根据不同类型、不同吨位的船舶对气体的需求及船舶的具体任务,而选择相应的气体制备工艺和装置。The present method of producing nitrogen and oxygen through air separation process was introduced in this paper. It was an effective solution to meet the needs of nitrogen and oxygen on a ship by installing air separation unit, using the cabin air as raw materials and site preparation. At present, combustion, pressure swing adsorption, membrane separation and cryogenic were four main methods of air separation technology. The four process principles, the implementation process, the feature and the adaptability of the ship were analyzed and compared. The current technical difficulties to be resolved were proposed. In the ship design process, the appropriate gas preparation technology and the equipments were selected according to the needs and the specific task of the ship.
