MUMBAI, India, Oct. 12 -- Intellectual Property India has published a patent application (202511025337 A) filed by Birla Institute Of Technology & Science, Pilani on March 20, 2025, for Process And System For Regeneration Of Meg, Deg & Teg From Complex Glycolic Waste.
Inventors include Jigyasha Srivastava; and Prakash Kumar B G.
The application for the patent was published on October 09, 2026, under issue no. 41/2026.
Abstract: [0041] The present invention discloses a method and system for sustainable recovery of high purity MEG, DEG and TEG from a complex glycolic waste mixture. In one embodiment, a method includes simulating a process of sustainable recovery of ethylene glycol components (MEG, DEG, TEG) using a regeneration unit based on feed characterization of a complex glycol containing water, aromatics, and glycolic waste mixture in a simulation environment. The method includes generating a control recipe for sustainable recovery of the ethylene glycol components from the feed stream of complex glycolic waste. The method includes executing the control recipe to regenerate high quality ethylene glycol components from the feed stream using a control system. [
