MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202617075570 A) filed by Toyo Engineering Corporation on June 18, 2026, for Urea Production Apparatus, Method For Improving Urea Production Apparatus, And Urea Production Method.
Inventors include Kawata Shogo; Yanagawa Takahiro; and Kojima Yasuhiko.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: A urea production apparatus (10) comprises: a first evaporator (EV1) for obtaining a first exhaust gas and a concentrated urea aqueous solution from a urea aqueous solution; a condenser (C1) for cooling the first exhaust gas to thereby obtain condensed water; a second evaporator (EV2) for obtaining a second exhaust gas and a high-concentration urea liquid from the concentrated urea aqueous solution; a granulation device (F) for obtaining a solid urea product from the high-concentration urea liquid; a scrubber (SCR) for bringing the second exhaust gas and a third exhaust gas discharged from the granulation device (F) into contact with a cleaning liquid to thereby obtain a clean gas and a post-cleaning recovery liquid containing an ammonium salt and urea; and a recovery pipe configured so as to supply the post-cleaning recovery liquid to the second evaporator (EV2). The second evaporator (EV2) obtains the high-concentration urea liquid and the second exhaust gas from a mixture liquid of the concentrated urea aqueous solution and the post-cleaning recovery liquid.
