摘　　要：我国化工、煤炭、电力等行业的崛起,给大型空分设备的发展带来了机遇。深入研究大型空分设备的相关技术,对促进我国气体工业高效节能发展具有重要意义。文章从系统联合的角度,探讨了大型空分设备在原料气、净化以及动力方面与其他工业用氧系统的联合形式,着重讨论了空分设备与天然气液化以及LNG冷能利用系统之间的联合技术。在此基础上通过举例,指出了联合流程中参数匹配的重要性,同时给出了一些解决办法。最后讨论了低温条件下板翅式换热器的性能变化及其对传热性能的影响。Development of chemical, coal and electrical power industry in China renders good opportunity to development of large-sized air separation plant and deep research of related technology of large-sized air separation plant is much essential to promote our effective and economical development of gas industry. Here, the combination form of the large-sized air separation plant in raw air, purification, and power with other industry-oxygen system is systematically approached, and the combination technology of air separation plant with NG liquefaction and LNG cryogenic energy utilization system is discussed in details. On this base through examples, the importance of parameters-matching in combined process is pointed and some solutions are raised. Finally, the change of performances of plate-fin heat exchanger under low temperature condition and its impact on heat transfer performance are discussed.
