摘要
概述了原油中砷化物的种类和脱除机理。对吸附脱砷和临氢脱砷技术的优缺点进行了对比分析,得出了临氢脱砷是今后的发展重点的结论。对国内外主流的临氢脱砷技术进行了系统总结,同时对柴油馏分脱砷技术的发展前景进行了展望。
In this paper,types of arsenide in crude oil and removal mechanism were introduced in detail.The advantages anddisadvantages for arsenide removal by adsorption and hydrogen were compared.It is concluded that arsenide removal by hydrogen will be the focus of development in the future.The technical status for hydrogenation de-arsenic technology were summarized systematically.The prospect of the hydrogenation de-arsenic technology from diesel fractions was also pointed out.
