- 摘要:
- 2016年,塔河油田二号联轻烃站所销售的轻烃出现异味,经化验分析发现轻烃总硫超出GB 9053-2013 《稳定轻烃》中相关要求。分析认为,轻烃中含有的乙硫醇等有机硫导致了硫含量超标。根据已建混烃碱洗脱硫装置能够较好脱除有机硫的实际运行效果,确定将轻烃接入已建混烃碱洗脱硫装置进行碱洗。改造方案一是对已建碱洗罐和水洗罐的进液管做局部改造,增设分布器;二是优化碱洗工艺流程,增设立式碱洗罐一座。改造项目实施后,轻烃经过碱洗工艺脱除了乙硫醇等有机硫,硫含量明显降低,达到了标准要求。
In 2016, the light hydrocarbons sold by Tahe oilfield light hydrocarbon station No.2 have given off peculiar smell. After laboratory analysis, it was found that the total sulfur light hydrocarbon was beyond relevant requirements in Stable Light Hydrocarbon 9053-2013 GB. After analysis, it is considered that the organic sulfur, such as the organic sulfur in the light hydrocarbon, leads to excessive sulfur content. According to the fact that established mixed hydrocarbon alkali washing desulfurization device can better remove the organic sulfur, it was determined to connect the light hydrocarbon with the existing mixed hydrocarbon alkali washing desulfurization device for alkali washing. Reconstruction scheme: one is to reconstruct the inlet tube of existing alkali wash tank and water tank and add distributor; another one is to optimize alkali washing process flow, add one vertical alkali washing tank. After reconstruction was carried out, ethanethiol was removed from light hydrocarbon by alkali washing process, and the sulfur content was obviously decreased, which meets the standard requirements.
