Description

一种原油脱硫剂
技术领域
本发明属于炼油工艺专用药剂，特别涉及一种用于原油的脱硫剂。
背景技术
硫在原油中大部分以有机硫的形式存在，含硫化合物的存在， 给石油加工过程和石油产品的质量带来了许多负面影响。对产品质量的影响：随着硫化合物的增多，采用一般的炼制方法，其直馏产品、催化裂化和焦化等二次加工产品的质量都较差，不能满足使用要求。对生产设备的腐蚀：在温度260-480℃范围内，含硫化合物对一般的钢材腐蚀严重，而这个温度范围正好是一般炼油装置的操作温度范围。炼油装置的高温重油部位和低温轻油部位腐蚀严重，因此，有的炼油设备材料要采用渗铝钢材、合金钢材或合金钢衬里，这就增加了装置的投资费用。在操作时要注碱、注氨、注缓蚀剂来减轻腐蚀，增加了操作费用。对环境污染： 含硫油品燃烧后生成二氧化硫，造成对环境的污染。
由于原油中硫化合物有以上诸多危害， 如果仅从后续加工解决问题会导致加工过程的操作难度和费用增加，影响工艺操作的平稳性及安全性，因此，需要添加原油脱硫剂来除去原油中的硫。
本发明提供的原油脱硫剂，能够有效降低硫含量，具有很高的活性和脱硫效果；能够减少对后续设备的腐蚀及硫引起的催化剂中毒；脱硫剂及脱硫产物不进入后续加工工艺，对产品质量无负面影响。该脱硫剂可以用于炼厂原油及干气、液化气及油田气、天然气中硫的脱除。
发明内容
本发明的目的在于提供一种原油脱硫剂；具有较高的H2S吸收选择性，保障原油和系统中的H2S低于指标要求，大大降低溶液循环量，减少能耗；能够减少对后续设备的腐蚀及硫引起的催化剂中毒；对产品质量无负面影响，适用于炼厂原油及干气、液化气及油田气、天然气中硫的脱除。
本发明所采用的技术方案如下：
一种原油脱硫剂，含有有机胺、缓蚀剂和水。各组分的重量百分比为：
有机胺 15～65%
缓蚀剂 10～20%
水 20～50%。
所述的有机胺为一乙醇胺、二乙醇胺、N,N-二甲基乙醇胺、N,N-二乙基乙醇胺中的一种或几种。
所述的缓蚀剂为六次甲基四胺、吗啉、哌嗪中的一种或几种。
所述的一种原油脱硫剂的制备方法：在反应釜中加入20 ～ 50％的水；然后向反应釜中加入10～20％的缓蚀剂，混合搅拌20～60分钟；向上述搅拌后的溶液中加入15 ～65％的有机胺，并搅拌20～60分钟。
实施例一
按重量百分比选取原料
一乙醇胺 50%
水 35%
六次甲基四胺 15%
所述的一种原油脱硫剂的制备方法：在反应釜中加入35％的水；然后向反应釜中加入15%的六次甲基四胺，混合搅拌50分钟；向上述搅拌后的溶液中加入50％的一乙醇胺，并搅拌60分钟。
实施例二
按重量百分比选取原料
N,N-二甲基乙醇胺 30%
水 50%
哌啶 20%
所述的一种原油脱硫剂的制备方法：在反应釜中加入50％的水；然后向反应釜中加入20%的哌啶，混合搅拌20分钟；向上述搅拌后的溶液中加入30％的N,N-二甲基乙醇胺，并搅拌20分钟。
实验一 脱硫实验
(1)称取柴油或原油 400g，分别在 30℃和 50℃下边搅拌边通入硫化氢气体，通入的硫化氢量控制在 300μg/g-500μg/g。原油通硫化氢前需进行预处理，在50℃下用氮气吹扫30min以上，保证原油中不含硫化氢；
(2)吸收硫化氢后的油分成两份，一份密封保存，一份经氮气吹扫，用碘量法检测硫化氢质量浓度，记为P1；
(3)根据检测到的硫化氢质量浓度，在另一份油中加入与硫化氢量相等的脱硫剂，置于密封容器中。在50℃下，以120次/min速度震荡（使柴油、 原 油与脱硫剂混合均匀），反应6h；
(4)打开脱硫后的密封容器，用碘量法测定剩余的硫化氢质量浓度，记为P2。则：脱硫率= (P1-P2)/P1*100％
每组实验应进行至少3次平行实验,将计算的平均值作为脱硫率的值。
从实验结果可以看出，该原油脱硫剂能够很好地脱除原油中的硫化氢。
