MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202647127219 A) filed by Schneiders, Servatius on October 26, 2026, for Caustic Concentration And Flaking Plant.
Inventor includes Schneiders, Servatius.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The invention concerns a caustic concentration and flaking plant comprising a caustic solution feeding line, a first stage evaporator (EV-2101) receiving membrane cell liquor with a 30 to 50 wt.- % caustic from the feeding line and operating at a reduced pressure of 80 to 120 mbar, a second stage evaporator (EV-2201) receiving enriched caustic solution with 45 to 60 wt.-% from the first evaporator (EV-2101) and operating at atmospheric pressure, a third stage evaporator (EV-2301) receiving further enriched caustic solution with 83 to 89 wt.-% caustic from the second stage evaporator (EV-2201) and operating at a reduced pressure of 120 to 210 mbar for KOH and 550 to 700 mbar for NaOH, the first stage evaporator (EV-2101) being heated by the vapours generated by the second stage evaporator (EV-2201), the second stage evaporator (EV-2201) and the third stage evaporator (EV2301) being heated by thermal oil provided by a heater (H- 6301), a closed loop with a circulation pump (P-6301) for circulating thermal oil between the heater (H-6301), and the second and third stage evaporators (EV-2201, EV-2301), a first condenser (C- 7301) receiving vapours generated by the first stage evaporator (EV-2101) and a second condenser (C-7302) receiving vapours generated by the third stage evaporator (EV-2301), a vapour condensate tank (T-7301) collecting vapour condensate from the first (C-7301) and second (C-7302) condenser and condensed heating vapour from the first stage evaporator (EV-2101), a caustic exit line feeding molten 92 to 99 % caustic to a flaking unit comprising at least one flaking machine (F-3111, F-3112).
