US Patent Issued to Circlia Nordic on Oct. 7 for "Cost efficient integration of hydrothermal liquefaction and wet oxidation wastewater treatment" (Danish Inventor)

ALEXANDRIA, Va., Oct. 8 -- United States Patent no. 12,435,277, issued on Oct. 7, was assigned to Circlia Nordic ApS (Aarhus, Denmark).

"Cost efficient integration of hydrothermal liquefaction and wet oxidation wastewater treatment" was invented by Ib Johannsen (Aarhus, Denmark).

According to the abstract* released by the U.S. Patent & Trademark Office: "Aqueous wastewater from hydrothermal liquefaction (HTL) systems is typically high in chemical oxygen demand (COD), which renders classic aerobic wastewater treatment to be prohibitively expensive. HTL wastewater can be processed using thermochemical wet oxidation in a manner that is not only cost efficient but also contributes more heat than is required for the energetically demanding HTL...
