摘要： Recovering high purity benzene from hydrocarbon feedstock containing aromatics and non-aromatics is implemented by simple and low-cost modifications to conventional extractive distillation columns (EDCs). Methyl cyclohexane (MCH) that is generated through non-selective hydrogenation of toluene in hydrodesulfurization (HDS) units is a major contaminant in benzene production. To meet MCH specifications, often times the extractive distillation (ED) process for recovering purified benzene is operated with excessive benzene loss to the overhead raffinate stream, producing a lower quality non-aromatic product. Novel techniques (1) remove operational constrictions of the HDS unit on MCH production, thus lengthening the catalyst life and (2) allow the EDC to drive essentially any amount of MCH away from the bottom benzene product without concerns with benzene loss to the overhead raffinate stream and (3) recover benzene from the overhead raffinate stream to upgrade the quality of non-aromatic product and increase the benzene product recovery.
摘要翻译：通过对常规萃取蒸馏塔（EDC）的简单且低成本的改进来实现从芳族化合物和非芳族化合物的烃原料中回收高纯度苯。通过在加氢脱硫（HDS）单位中甲苯的非选择性氢化产生的甲基环己烷（MCH）是苯生产中的主要污染物。为了满足MCH规范，通常多次用于回收纯化苯的萃取蒸馏（ED）方法对顶部萃余液流具有过量的苯损失，产生较低质量的非芳族产物。新技术（1）消除了HDS单元在MCH生产中的操作限制，从而延长了催化剂寿命，（2）允许EDC将基本上任意数量的MCH从底部苯产品中驱出，而不考虑苯残留到塔顶残液流和（3）从塔顶残液流回收苯，提高非芳香族产品的质量，提高苯产品回收率。
