| Improving mercaptan solubility |
Stephen A Bedell, Linda L Pirtle and John M Griffin, The Dow Chemical Company
|
2007 / Gas |
While mercaptan removal by amines in most gas treating operations is very dependent on solution pH and lean load, these new agents are mostly independent of pH changes encountered in normal gas treating operations.
