2003年12月4日杭氧股份公司为中石化湖北、安庆分公司化肥原料“油改煤”工程配套的两套48000m~3/h成套空分设备的中标书签字仪式在杭隆重举行。这次杭氧股份有限公司中标的两套48000m~3/h空分设备是为推进化肥原料结构调整及炼油化厂资源优化工程实施而配套的。实现零的突破,一直是杭氧人孜孜以求的目标。自1955年试制成第一套30m~3/h空分设备后,走过了采用高低压铝带蓄冷器流程,全低压石头蓄冷器切换流程,板翅式换热器切换流程,常温分子筛吸附流程,带增压膨胀机的分子筛净化流程,直到现在采用规整填料上塔与全精馏制氩流程,液
On December 4, 2003, the signing ceremony of two winning sets of two sets of 48000m ~ 3 / h air separation plants for Hangyang Oxygen Co., Ltd., a fertilizer raw material of Sinopec Hubei and Anqing Branch, was carried out in Hangzhou. The Hangyang Oxygen Co., Ltd. won the bid two sets of 48000m ~ 3 / h air separation plant is to promote the chemical fertilizer raw material structure adjustment and refinery resources optimization project implementation and supporting. To achieve zero breakthrough, has been Hang Oxygen people pursued the goal. Since 1955 trial production of the first set of 30m ~ 3 / h air separation plant, through the use of high and low pressure aluminum cold accumulator flow, full low pressure stone regenerator switching process, plate-fin heat exchanger switching process, room temperature molecular sieve Adsorption process, with a turbocharger molecular sieve purification process, until now the use of structured packing on the tower and the whole distillation process argon, liquid
