MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202617056583 A) filed by Dow Global Technologies LLC on May 04, 2026, for Methods And Systems For Preparing Gas-Phase Feedstock.
Inventors include Beneke, Daniel; and Hagen, Henk.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: Embodiments of the present disclosure are directed towards a method and system for preparing a gas-phase feedstock. The method and system for preparing a gas-phase feedstock for a reactor section of a cracking furnace having a convection section coupled to the reactor section includes preheating a hydrocarbon blend in a feed preheating exchanger (FPH) located in the convection section of the cracking furnace to form a preheated hydrocarbon blend, where the hydrocarbon blend includes a fossil-based hydrocarbon feedstock and a circular feedstock oil. The method and system also includes mixing the preheated hydrocarbon blend with dilution steam to form a hydrocarbon-water gas-liquid feed mixture, separating the hydrocarbon-water gas-liquid feed mixture into a liquid phase and the gas-phase feedstock, and supplying the gas-phase feedstock to a high temperature coil exchanger (HTC) of the cracking furnace.
