中国自主突破120万吨级乙烯装置核心技术

2018-12-12 18:31:03    新华网

新华社沈阳12月12日(记者石庆伟)记者从沈鼓集团了解到,由沈鼓集团研制的我国首套“120万吨/年乙烯装置用离心压缩机组”近日通过了中国机械工业联合会、中国通用机械工业协会等单位组织的产品鉴定。“该装置已于2017年11月27日在中海壳牌石油化工有限公司二期项目中一次试车成功,实现持续稳定运行。”沈鼓集团董事长戴继双表示,“这是我国大乙烯装备国产化的一次重大技术突破。”

离心压缩机组是乙烯装备的“心脏”,一旦出现问题,将会给乙烯生产造成不可挽回的巨大损失。全球只有美国、德国、日本等少数发达国家具有百万吨级乙烯压缩机制造能力。

近年来,沈鼓集团坚持自主创新,接连打破国际垄断,实现了80万吨、100万吨、120万吨级乙烯装置研制的“三级跳”。中海壳牌二期项目采用的120万吨级乙烯装置,是全球规模最大的乙烯装置之一,其核心设备裂解气、乙烯、丙烯压缩机组全部由沈鼓集团研制和安装。

在对主要技术指标及性能、实际运行情况等逐项进行审核之后,国内流体机械专业和石化行业的14位专家、院士组成的鉴定委员会认为,沈鼓集团研制的“120万吨/年乙烯装置用离心压缩机组”填补了国内空白,机组整体性能达到国际同类产品先进水平。

据介绍,从自主研发出我国第一台乙烯压缩机以来,沈鼓集团已累计生产各类乙烯装置用压缩机68台套。业界专家认为,沈鼓集团“120万吨/年乙烯装置用离心压缩机组”的成功研制、稳定运行并通过鉴定,标志着我国已经攻克了百万吨级大型乙烯装置关键设备的核心技术。
