MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611024931 A) filed by Ekagrah Singh; and Sarita Pragya, Hathras, Uttar Pradesh, on March 3, for 'an integrated multistage system for mineral recovery and solvent purification from saline feedstocks.'
Inventor(s) include Ekagrah Singh.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "In the present invention multistage integrated system and process for recovery of inorganic materials and purification of solvent from saline solutions is disclosed. The system operates as a closed-loop saline refinery (10) combining chemical precipitation, osmotic concentration, thermal regeneration, and staged electrochemical extraction. In a first stage, selective solid precipitation in a selective solid precipitation reactor (20) reduces ionic load by forming recoverable alkaline earth compounds. A forward osmosis concentration module (30) employing a thermolytic draw solution circuit (31) extracts purified solvent while concentrating residual solutes. A thermal regeneration system (40), driven by low-grade or waste heat through a low-grade heat utilization interface (41), regenerates and recycles the draw solution. Differential electrochemical recovery is carried out in a differential electrochemical recovery assembly (50) comprising a low-voltage electrolysis cell (51) and a high-voltage electrolysis cell (52) to selectively recover halogen species. A downstream chemical stabilization and scrubbing unit (70) converts reactive species into transportable solid products. The system enables zero liquid discharge operation while producing purified water, mineral products, and recoverable energy carriers."
