METHODS AND SYSTEMS FOR PRODUCING OLEFINS AND AROMATICS FROM COKER NAPHTHA

Methods and systems for producing olefins and aromatics are provided. Methods can include removing silica from the coker naphtha feedstock to produce a first effluent, hydrogenating the first effluentto produce a second effluent, reacting the second effluent to produce a third effluent comprising aromatics, a fourth effluent comprising olefins, and a fifth effluent, separating the fourth effluentto produce a propylene product stream, an ethylene product stream, and a sixth effluent, recycling the sixth effluent by combining it with the second effluent. 提供了用于生产烯烃和芳烃的方法和系统。方法可以包括从焦化石脑油原料中除去二氧化硅以产生第流出物，氢化第流出物以产生第二流出物，使第二流出物反应以产生包含芳烃的第三流出物、包含烯烃的第四流出物、和第五流出物，分离第四流出物以产生丙烯产物流、乙烯产物流和第六流出物，通过将第六流出物与第二流出物合并使第六流出物再循环。
