在许多石油产品中特别是在含硫原油的轻质油品中都有不同程度含量的硫醇 ,硫醇的存在不仅使油品产生恶臭 ,而且使油品的质量和安定性下降 ,硫醇本身还具有腐蚀性。为此 ,在炼油工业中常常需要将硫醇脱除 (即脱臭 )。本文介绍了国内外开发应用的脱臭工艺以及助催化剂、活化剂的研究进展 ,对我国目前轻质油品脱臭技术的研究开发提出建议。
In many petroleum products, especially in light oil products containing sulfur crude oil, there are varying degrees of content of mercaptans. The presence of mercaptans not only makes the oil produce bad smell, but also reduces the quality and stability of the oil products. The mercaptan It is also corrosive. For this reason, it is often necessary to remove mercaptans (ie, deodorize) in the oil refining industry. This paper introduces the development of deodorization process at home and abroad as well as cocatalyst and activator, and makes some suggestions on the research and development of light oil deodorization technology in our country.
