MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202647122562 A) filed by Khd Humboldt Wedag Gmbh on October 13, 2026, for System And Process For Producing Cement Together With The Separation Of Carbon Dioxide.
Inventors include Gussmann, Rolf; Knoch, Alexander; Mersmann, Matthias; Naha, Avipsha; and Sellmann, Johannes.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The invention relates to a process for producing cement clinker (11) from raw meal (120), the process comprising the following steps: preheating (10) the raw meal (120) to form hot meal (122); separating (20) the hot meal (122) in a cyclone separator (161); and introducing the hot meal (122) via a hot-meal line (163) into an entrained-bed reactor (170); calcining (30) the hot meal (122) to form deacidified raw meal (121) in the entrained-bed reactor (170) as a calciner; separating (40) the deacidified raw meal (122) in a cyclone separator (177) downstream of the entrained-bed reactor (17), as the calciner, in the gas-flow direction; sintering (40) the separated, deacidified raw meal (121) in a rotary kiln (170) to form cement clinker (110). The invention also relates to a system corresponding thereto. According to the invention, the raw meal (120) is preheated (10) to form hot meal (122) in an entrained-bed reactor (160) as the first entrained-bed reactor and the exhaust gases of the rotary kiln (130) are applied (55) to said first entrained-bed reactor (160).
