RE: H2S and mercaptans removal from crude oil??
-mercaptans can also be formed by decomposition of organic sulphur compounds during normal processing.
-H2S is formed by thermal and catalytically decomposition of sulphur compounds during distillation, cracking, reforming, etc.
The technical literature is full of commercial processes used for their removal by using soda at one end up to hydotreating at the other.

Normally, you stabilize crude to remove the light ends to meet vapor pressure requirements (eg. before it is stored in floating roof tanks or exported) but it can also be used to remove H2S down to the low ppm range by increasing the bottoms temperature. I know Aramco uses this frequently on some of their crude oil streams. I would not expect this to remove mercaptans though.
