MUMBAI, India, Aug. 31 -- Intellectual Property India has published a patent application (202541015573 A) filed by Hindustan Petroleum Corporation Limited on February 22, 2025, for Process For Valorization Of Pitch From Residue Upgradation Unit Alongwith Production Of High Modulus Bitumen.
Inventors include Doni, Eswararao; Madala, Sairamu; Gulati, Susheel; Bal, Ankita Number; and Srinivasa Narasimha, Sheshachala.
The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: The present invention discloses a process for valorization of pitch from residue upgradation unit in refinery to High Modulus Bitumen (HMB). The process includes heating a short residue in a first reactor to a temperature in a range of 160-220oC, wherein additional components are added into the heated short residue. Wherein, the additional components are selected from additional refinery streams, chemical additives and a combination thereof. Then heating said pitch in a second reactor to a temperature of 220-300oC. Then mixing the heated short residue into the heated pitch to get a mixture, wherein, the mixture is stirred at 400 RPM - 5000 RPM at 160-220°C for 15-60 minutes to prepare the High Modulus Bitumen (HMB).
