RRT全球公司开发的PRIS新工艺,用C5~C6轻烃与苯馏分在反应蒸馏塔中进行异构化,使汽油中的苯含量降至接近零,使炼厂的汽油产品能满足美国移动空气毒物II(MSAT II)规格要求,同时保持辛烷值(RON)不变。PRIS新工艺降低苯含量是在反应蒸馏塔中在热力学限制范围内使苯饱和后异构化变为甲基环戊烷,与C5和C6馏分异构化油一道作为高辛烷值调合组分,
The PRIS new process developed by RRT Global Company uses isomerization of C5 to C6 light hydrocarbons and benzene fractions in a reactive distillation column to reduce the benzene content in the gasoline to near zero so that the gasoline products of the refinery will meet U.S. mobile air Poison II (MSAT II) specifications, while maintaining the octane number (RON) unchanged. PRIS new technology to reduce the benzene content in the reactive distillation column in the thermodynamic limits of benzene isomerization after isomerization into methylcyclopentane, and C5 and C6 fraction isomerized oil as high octane blend group Minute,
