MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202411020611 A) filed by Hpcl - Mittal Energy Limited, Bathinda, Punjab, on March 19, 2024, for 'a method and system for reducing coke yields and enhancing distillate yield in delayed coking operations.'
Inventor(s) include Mr. Yogesh Chaudhary; Mr. Uttam Kumar; Mr. Mohan Gopal; Mr. Parag Ambalal Patel; and Mr. Ashok Kumar Singh.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "This present invention provides a method and system for reducing coke yields and enhancing distillate yield in delayed coking operations. The process involves feeding vacuum residue to a main fractionator, passing it through coker drums and a furnace for thermal cracking, and introducing heavy coker gas oil (HCGO) into the coke drum vapor line to elevate the after quench temperature of coke vapors. By optimizing quench temperature and employing precise temperature control using Resistance Temperature Detectors (RTDs), the invention achieves a substantial reduction in coke yield and increased distillate production. The integrated system includes a flow control valve, ensuring automated operation. The present invention enhances coking process efficiency without compromising unit reliability, offering significant benefits for petroleum refining operations."
