Process for recovery of hydrate inhibitors

The present invention provides a process for recovering glycol from a process stream comprising glycol, water, dissolved salts, and hydrocarbons. The process comprises subjecting the process stream to a salt-enrichment process to obtain a salt-enriched stream having a salt concentration higher than salt concentration of the process stream, and a salt-reduced stream; subjecting the salt-enriched stream to a glycol reclaiming process to separate the salts and at least a portion of the hydrocarbons from the salt enriched stream to obtain a substantially salt-free water-glycol stream; and blending the salt reduced stream from the salt-enrichment process with the substantially salt-free stream to produce a reclaimed water-glycol stream.

A composition, apparatus, and method for enabling improved disposal of hydrogen sulfide are disclosed. An exemplary embodiment provides a method. The method includes receiving a brine stream comprising hydrogen sulfide. The method includes removing the hydrogen sulfide from the brine stream to generate hydrogen sulfide gas and a pretreated brine stream. The method includes processing the pretreated brine stream to produce a return brine stream. The method includes combining the hydrogen sulfide gas with the return brine stream under compression to generate a disposable waste stream.
