Processes and compositions for scavenging hydrogen sulfide from hydrocarbon streams are disclosed that reduce, if not substantially eliminate, the formation of crystalline or amorphous solids even under cold conditions. The compositions used in the processes comprise a hexahydrotriazine component and an amphiphilic component that form a hydrophobic micelle when the hexahydrotriazine component becomes spent.
本发明公开了从碳氢化合物流中清除硫化氢的工艺和组合物,即使在低温条件下,也能减少甚至基本消除结晶或无定形固体的形成。工艺中使用的组合物包括六氢三嗪成分和两亲成分,当六氢三嗪成分用完时,两亲成分会形成疏水胶束。
