为解决高酸原油常规加工对常减压蒸馏装置带来的腐蚀问题，采用减压蜡油掺炼高酸原油和单炼高酸原油两种加工方案，进行了高酸原油直接催化裂化技术的工业应用试验。结果表明：对于两种工况，经电脱盐单元处理后原料的钠含量和水含量均满足催化裂化单元的要求；催化裂化单元均可得到较好的产品分布，脱酸率均大于99％；催化裂化单元的主要液体产品酸度或酸值均满足产品标准的要求或后续加工工艺的要求。

Conventional methods processing high acid crude cause serious corrosion problems on at-mosphere and vacuum distillation unit.A new technology that the high acid crude is directly processed by FCC unit is developed to avoid these problems.Two kinds of commercial trial solutions were imple-mented:one is the blending feed of vacuum gas oil and high acid crude;another is the only acid high crude used as FCC feed directly.The commercial results show that the qualities for the two feeds after desalting and dewatering can meet the FCC feed requirements of sodium and water content.The perfect FCC product distribution can be obtained and deacidification is over 9 9% in both cases.The acidity or acid value of the product meet the standards or downstream process requirements.Processing the blend-ing feed can obtain better benefits.
