Solubility of Metal Sulfides | Soluble or Insoluble?

Can sodium sulfide is used to recover hydrogen sulfide in petroleum industry. First of all, I should say, this is an idea. After hydrogen sulfide and other effluent gases are separated in the refining process, it should be sent to aqueous concentrated NaOH solution to produce sodium sulfide. Then other gases are removed.
