    • High rate gas stripping for removal of sulfur-containing components such as mercaptans from crude oil may be conducted by feeding sweet gas to the bottom of a tower containing pre-heated mercaptan-containing crude oil feed. The gas bubbles up through the crude becoming enriched with H2S, mercaptans, CO2 and/or hydrocarbons. The rich gas exits the tower, and is treated to produce a sweetened gas, a portion of which is recycled to the tower, and an acid gas. The remainder of the sweetened and/or the acid gas may be used as a fuel or processed to recover a portion of any hydrocarbons that may have been stripped out of the crude oil with the mercaptans, sulfur-containing components, CO2, used for enhanced oil recovery or disposed.
    • 用于从原油中除去含硫组分如硫醇的高速汽提可以通过将甜气馈送到含预热的含硫醇原油进料的塔的底部来进行。 气体通过粗气体向上膨胀,富含H 2 S,硫醇,CO 2和/或烃。 富氧气体离开塔,并被处理以产生增甜气体,其一部分再循环到塔中,并产生酸气。 甜味气体和/或酸性气体的其余部分可以用作燃料或加工以回收可能用硫醇,含硫组分,用于增强的含硫组分,二氧化碳,可能已被从原油中汽提的任何烃的一部分 油回收或处置。
