摘要：
Trace amount levels of heavy metals such as arsenic in crude oil are reduced by contacting the crude oil with an oxidizing agent, extracting heavy metals into a water phase for subsequent separation from the crude oil. In one embodiment, the oxidizing agent is selected from the group of hydroperoxides, organic peroxides, inorganic peracids and salts thereof, organic peracids and salts thereof, halogens such as iodine (I2), bromine (Br2), and ozone. In one embodiment, at least a complexing agent selected from the group of metal m halides and/or sulfur compounds can be added to facilitate the removal of arsenic from crude oil by forming soluble heavy metal complexes in the water phase.
摘要（中）：
通过使原油与氧化剂接触，将原油中的重金属如砷的微量水平降低，将重金属萃取到水相中，随后与原油分离。 在一个实施方案中，氧化剂选自氢过氧化物，有机过氧化物，无机过酸及其盐，有机过酸及其盐，卤素如碘（I 2），溴（Br 2）和臭氧。 在一个实施方案中，可以加入至少一种选自金属卤化物和/或硫化合物的络合剂，以便于通过在水相中形成可溶性重金属络合物从原油中除去砷。
