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 A LA OTRA PLANTA, DONDE CADA EFECTO DE EVAPORACIÓN COMPRENDE AL MENOS UNA UNIDAD CON UNA SUPERFICIE PARA TRANSFERENCIA DE CALOR Y TIENE CONDUCTOS PARA LLEVAR UN LIQUIDO 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 LIQUIDO. UNA UNIDAD DE LA PLANTA DE EVAPORACIÓN POR COMPRESIÓN DE VAPOR Y UNA UNIDAD DE LA PLANTA DE EVAPORACIÓN MULTIEFECTO CONECTADA EN SERIE A LA OTRA PLANTA SE ACOPLAN DE TAL MANERA QUE LOS VAPORES QUE. SE GENERAN POR LA EVAPORACIÓN DEL LIQUIDO 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 TO EVAPORATE A LIQUID, FOR EXAMPLE BLACK LIQUOR, INCLUDING AT LEAST ONE VAPOR COMPRESSION EVAPORATION PLANT INCLUDING AT LEAST ONE UNIT WITH A SURFACE FOR HEAT TRANSFER AND A DEVICE FOR INCREASING THE VAPOR AND PRESSURE MULTI-EFFECT EVAPORATION PLANT CONNECTED IN SERIES TO THE OTHER PLANT, WHERE EACH EVAPORATION EFFECT INCLUDES AT LEAST ONE UNIT WITH A SURFACE FOR HEAT TRANSFER AND HAS PIPES TO CARRY A LIQUID FROM AN EVAPORATION UNIT AND ANOTHER HEAT TRANSFER UNIT BY TRANSFER TO SUPPLY STEAM TO EACH OF THE UNITS AND TO DISCHARGE FROM THE SAME THE VAPOR GENERATED BY THE EVAPORATION OF THE LIQUID. ONE UNIT OF THE VAPOR COMPRESSION EVAPORATION PLANT AND ONE UNIT OF THE MULTI-EFFECT EVAPORATION PLANT CONNECTED IN SERIES TO THE OTHER PLANT ARE COUPLE IN SUCH A WAY THAT THE VAPORS THAT. THEY ARE GENERATED BY THE EVAPORATION OF THE LIQUID IN THE UNITS THEY ARE TAKEN TOWARDS A COMMON SPACE THAT IS CONNECTED TO AT LEAST ONE DEVICE TO INCREASE THE PRESSURE OF THE VAPOR TO BRING A PORTION OF THE STEAM TOWARDS THE SAME AND TO MAKE A VAPOR RETURN AFTER THE PRESSURE INCREASE TO THE UNIT OF THE EVAPORATION PLANT BY COMPRESSION OF VAPOR TO USE IT AS A MEDIA FOR HEATING. A SECOND PORTION OF THE VAPOR CAN BE CONDUCTED TO THE NEXT EFFECT OF THE SERIES CONNECTED MULTI-EFFECT EVAPORATION PLANT.
