    • The continuous process for removing mercury comprises a step of continuously feeding a mercury-containing liquid hydrocarbon to an ionization zone where the elementary mercury is ionized; and a step of continuously feeding the liquid hydrocarbon containing the ionized mercury to a sulfur compound-treatment zone where the ionized mercury is converted to a solid mercury compound. The semi-continuous process for removing mercury comprises a step of continuously feeding a mercury-containing liquid hydrocarbon to an ionization column where the elementary mercury is ionized; and a step of feeding the liquid hydrocarbon containing the ionized mercury to a sulfur compound-treatment tank where the ionized mercury is converted to a solid mercury compound in batch manner. With the above processes, the mercury is removed from the liquid hydrocarbon with ease in a continuous or semi-continuous manner at around ordinary temperature under around ordinary pressure.
    • 用于去除汞的连续方法包括将含汞液体烃连续供给到基本汞被离子化的电离区的步骤; 以及将含有电离汞的液态烃连续供给到硫化合物处理区域的步骤,其中电离汞转化为固体汞化合物。 用于去除汞的半连续方法包括将含汞液体烃连续供给到基本汞离子化的离子化柱的步骤; 以及将含有电离汞的液体烃进料到硫化合物处理槽中的步骤,其中电离汞以分批方式转化为固体汞化合物。 通过上述方法,在大约常压下在大约常压下,以连续或半连续的方式容易地从液态烃中除去汞。
