Latest Patents

Liu's latest patents include methods for treating produced water concentrate. One patent describes a process where produced water, such as that from steam-assisted gravity drainage (SAGD) or cyclic steam stimulation (CSS), is treated to recover water for reuse in steam generation. This involves concentrating the produced water using thermal treatment devices like evaporators and crystallizers. A solvent and a solution containing multivalent cations are added to the concentrate, leading to the precipitation of solids that can be separated and reused.

Another patent addresses the treatment of produced water and solids precipitation from thermal treatment blowdown. In this process, produced water is treated to recover reusable water for steam creation. The thermal treatment generates a slurry with dissolved salts and organic compounds. A water-miscible solvent, such as methanol, is introduced to the slurry, resulting in the precipitation of solids that can be separated and reused.
