AMMONIA AND CARBON DIOXIDE DISTILLATION PLANT IN SODS ASH PRODUCTION Russian patent published in 1997 - IPC

Abstract RU 2097324 C1

FIELD: chemical engineering. SUBSTANCE: plant contains condenser- cooler for distillation gas, distillation heat exchanger, distiller, mixer, evaporator, and initial steam-supply pipeline. Novelty consists in providing plant with evaporator connected with (i) distiller through secondary steam line, (ii) distillation heat exchanger through line for solution being evaporated, and (iii) mixer through evaporated solution line. The latter line has restrictor means. Line for solution being evaporated includes intermediate vessel with pump; distillation heat exchanger is connected with this vessel and discharge pipe of pump with evaporator. EFFECT: improved process flowsheet. 3 cl
