Abstract

Una disposición para evaporar un líquido, como por ejemplo licor negro, que comprende al menos una planta de evaporación por compresión de vapor que incluye al menos una unidad con una superficie para transferencia de calor y un dispositivo para aumentar la presión del vapor, y una planta de evaporación multiefecto conectada en serie, donde cada efecto de evaporación comprende al menos una unidad con una superficie para transferencia de calor y tiene conductos para llevar un líquido desde una unidad de evaporación por transferencia de calor hacia otra unidad y conductos para alimentar vapor a cada una de las unidades y para descargar desde las mismas el vapor generado por la evaporación del líquido. Una unidad de la planta de evaporación por compresión de vapor y una unidad de la planta de evaporación multiefecto conectada en serie se acoplan de tal manera que los vapores que se generan por la evaporación del líquido en las unidades son llevados hacia el interior de un espacio en común que está conectado al menos a un dispositivo para aumentar la presión del vapor para llevar hacia el mismo una porción del vapor y para hacer retornar a dicho vapor después del aumento de presión a la unidad de la planta de evaporación por compresión de vapor para usarlo como medio para el calentamiento. Una segunda porción del vapor se puede conducir hacia el próximo efecto de la planta de evaporación multiefecto conectada en serie.An arrangement for evaporating a liquid, such as black liquor, comprising at least one vapor compression evaporation plant that includes at least one unit with a surface for heat transfer and a device for increasing vapor pressure, and a multi-effect evaporation plant connected in series, where each evaporation effect comprises at least one unit with a surface for heat transfer and has ducts for carrying a liquid from one evaporation unit by heat transfer to another unit and ducts for feeding steam to each of the units and to discharge from them the steam generated by the evaporation of the liquid. A unit of the vapor compression evaporation plant and a unit of the multi-effect evaporation plant connected in series are coupled in such a way that the vapors that are generated by the evaporation of the liquid in the units are brought into a space in common that it is connected to at least one device to increase the vapor pressure to carry a portion of the steam thereto and to return said steam after the pressure increase to the steam compression evaporation plant unit for Use it as a means for heating. A second portion of the steam can be driven to the next effect of the multi-effect evaporation plant connected in series.
