A system and a method for removing gas field chemicals from a feed stream are provided. An exemplary method includes performing a forward osmosis on a feed stream including gas field chemicals to form a concentrated feed stream, and treating the concentrated feed stream in an electrochemical process to form treated water.

Decomposition of gas field chemicals

A method of desalinating an aqueous composition includes forming a hetero-azeotrope mixture by combining the aqueous composition with an entrainer, the aqueous composition including at least one salt, and subjecting the hetero-azeotrope mixture to distillation at a distillation temperature of less than the boiling temperature of the aqueous composition for an operating distillation pressure, resulting in separating the hetero-azeotrope mixture into a distillation bottoms liquid and a multi-phase condensate. The method includes recovering the multi-phase condensate having an entrainer-rich phase and an aqueous phase, the aqueous phase comprising desalinated water, and removing a portion of the aqueous phase from the multi-phase condensate to recover the desalinated water. Systems for conducting the method of desalinating an aqueous stream are also disclosed.

Disclosed is a copper coated stainless-steel hydrophobic mesh and a method for synthesizing the hydrophobic mesh. In the method, a stainless-steel mesh is sonicated in a solution of acetone and ethanol, and then electroplated in a copper solution to form a copper coating on the surface of the mesh. The copper-coated stainless-steel mesh is treated with an oxidizing solution having an oxidizing potential applied to it. The mesh is then washed with water and dried. The copper-coated stainless-steel mesh is then immersed in a lauric acid solution. The mesh is then rinsed with ethanol to remove adsorbed lauric acid. After drying, the so-synthesized copper-coated stainless-steel hydrophobic mesh is characterized in that it has hydrophobic branches of lauric acid.
