Abstract: A process for removing non-volatile, particulate mercury from crudes and condensates is disclosed. Particulate mercury in crudes can be removed by a process of first adding a halogen, such as I2. The halogen converts at least 10% of the particulate mercury into an oil-soluble mercury compound that cannot be removed by filtration or centrifugation. This oil-soluble mercury compound can then be removed by adsorption onto a solid adsorbent. The process can operate at near ambient conditions. The adsorption step can be carried out by mixing a particulate adsorbent in the halogen-treated crude and then removing it by centrifugation, desalting, filtration, hydrocyclone or by settling.

Abstract translation: 公开了从原油和冷凝物中除去不挥发性微粒汞的方法。 可以通过首先加入卤素如I2的方法除去原油中的微粒汞。 卤素将至少10％的微粒汞转化为油溶性汞化合物，其不能通过过滤或离心除去。 然后可以通过吸附到固体吸附剂上去除该油溶性汞化合物。 该过程可在近乎环境条件下运行。 吸附步骤可以通过在卤素处理的粗品中混合颗粒吸附剂，然后通过离心，脱盐，过滤，水力旋流器或沉降来除去来进行。
