提高二空分液氮产量的探索与实践

Exploration and practice of increasing liquid nitrogen output of secondary air separation

针对独山子石化公司化工管网用氮需求,结合空分装置生产现状对二空分液氮产量的提升进行探索与实践,进一步提高液氮储备能力,提高空分装置在事故状态下的应对能力。

In view of the nitrogen demand of the chemical pipeline network of Dushanzi Petrochemical Company,and in combination with the production status of the air separation unit,explore and practice the improvement of the liquid nitrogen output of the secondary air separation unit,further improve the liquid nitrogen storage capacity,and improve the response capacity of the air separation unit under accident conditions.
