在空气分离装置中产生加压气态产品的低温空气分离方法
摘要：
一种在使用蒸馏塔系统(10、11)的空气分离装置中用来产生加压气态产品的低温空气分离过程及设备，其包括：在换热管路(30)内冷却一压缩空气流束以形成压缩的冷却空气流束、输送至少一部分压缩的冷却空气流束至系统的一个塔中、液化(60)工业流束(47)以形成第一液体产品、储存至少一部分第一液体产品到储存罐(50)、将储存罐中的至少一部分上述第一液体产品作为供给(60、61)之一输送至空气分离装置、从塔系统的一个塔中提取至少一第二液体产品流束，并压缩该至少一第二液体产品流束(6)、在换热管路里汽化上述压缩的第二液体产品流束以形成加压气态产品，并提取冷气体(40)(在换热管路里完全没有被加热)。
摘要（英）：

A low temperature air separation process and apparatus for producing pressurized gaseous product in an air separation unit using a system of distillation columns (10,11) which include cooling a compressed air stream in a heat exchange line (30) to form a compressed cooled air stream, sending at least part of the compressed, cooled air stream to a column of the system, liquefying (60) a process stream (47) to form a first liquid product, storing at least part of the first liquid product in a storage tank (50), sending at least part of the above first liquid product from the storage tank to theair separation unit as one of the feeds (60,61), extracting at least one second liquid product stream from a column of the column system and pressurizing the at least one second liquid product stream(6), vaporizing the above pressurized second liquid product stream to form pressurized gaseous product in the heat exchange line and extracting a cold gas (40)(without warming it completely in the heat exchange line).
