Application and optimization of 600 kt/a isooctane facility

浙江宁波某公司60万t/a异辛烷装置采用美国CB&I Lummus公司低温硫酸法烷基化技术CDAlky工艺,是目前世界上最大规模工业异辛烷生产装置。自2014年7月该装置首次开车成功后运行了近3年时间,期间对原料质量、腐蚀防护等进行优化,目前装置运行正常,达到高负荷高质量长周期运行的目标。

The 600 000 t/a isooctane facility of a company in Ningbo,Zhejiang,uses CDAlkyAdvanced Sulfuric Acid Alkylation from CBI Lummus and so far is still the world＇s largest industrial facility to produce isooctane.Since the initial startup in July 2014,the company has successfully operated the facility for nearly three years,while has carried out optimization on the issues such as the feedstock quality and corrosion prevention,etc.At present,the facility runs normally and achieves long-term operation with heavy load and robust performance.
