Description
技术领域
本发明属于脱硫技术领域，具体涉及一种中间馏分油脱硫装置。
背景技术
在现有技术中，脱硫有两种常用方式，分别为氢化脱硫方法和氧化脱硫方法。氢化脱硫方法：该技术使用氢从中间馏分油中除硫。因为该过程使用气体（氢），液体（中间馏分油），固体（催化剂），所以需要中间馏分油滴到催化剂的表面上，每一个氢化反应器需要至少是 30 英尺高。另外该过程是一个平衡反应，这意味着该过程需要一系列的反应器。运行的成本很高，因为高的氢气价格、安全与风险预防程序与设备。其他的是会导致柴油更少的润滑性。
氧化脱硫方法：氧化的脱硫技术基于以下事实：氧硫化合物更多的极性、容易被溶剂分（多数的应用过程是氰化甲烷）。该过程的问题是: 一些中间的馏分油也被氧化。氧硫化合物变成副产品，并且没有解决方案。中间馏分油溶解于氰化甲烷，反之亦然。为了分离中间馏分油、氧化物、氰化甲烷，需要一个馏分体系。
上述两个脱硫方法分别存在不同的缺陷：氢化脱硫方法使用贵金属作为原料，气体价格昂贵，维护成本高，能耗较高，且使用高危险性气体，操作危险性高。氧化脱硫方法使用催化剂，催化剂不能重复利用，需要过氧化物催化，成本高，且需要昂贵的相转移催化剂，过氧化物危险性高。
发明内容
本发明为了弥补现有技术的缺陷，提供了一种中间馏分油脱硫装置。
本发明是通过如下技术方案实现的：
一种中间馏分油脱硫装置，包括原油罐、脱硫反应罐和吸附剂再生罐，所述原油罐通过原油泵与脱硫反应罐连通，脱硫反应罐经固液分离器与吸附剂再生罐连通，脱硫反应罐上连通有吸附剂储存罐。
进一步，所述吸附剂再生罐内底部设有超声波发生器。
进一步，所述吸附剂储存罐内的吸附剂其原料组成按质量配比为：分子筛颗粒20-50份；乙醇溶液60-95份；氧化锌9-16份；二氧化锰溶液10-20份。
本发明的有益效果是：本发明一种中间馏分油脱硫装置可以重复使用，具有很长的使用寿命，加工成本低，不但可以得到超低硫的精制汽油产品，而且辛烷值损失少、氢耗少、液收率高和能耗低。
