Abstract

PROCEDIMIENTO DE TRATAMIENTO PARA PLANTAS DE SINTESIS DE AMONIO O UREA. ES APLICABLE EN LOS PROCEDIMIENTOS DE SINTESIS EN LOS QUE UN PRODUCTO RELATIVAMENTE NO VOLATIL, LA MATERIA PRIMA RESIDUAL SIN REACCIONAR, Y EL DISOLVENTE SE HACEN PASAR A TRAVES DE UNA SECCION DE EVAPORACION PARA LA CONCENTRACION DEL PRODUCTO Y LA ELIMINACION DE LA MATERIA Y EL DISOLVENTE, Y A TRAVES DE LA CUAL SE HACE PASAR UNA CORRIENTE AEREA VAPOROSA. CONSISTE EN: PONER DICHA CORRIENTE AEREA EN RELACION DE TRANSFERENCIA TERMICA Y DE MASA CON UNA CORRIENTE DE AGUA DE CONDENSACION; LA CORRIENTE DE CONDENSACION, RICA EN PRODUCTO Y POBRE EN MATERIA PRIMA, RESULTANTE DE LA FASE DE TRANSFERENCIA SE SUMINISTRA, COMO UNA CORRIENTE DEL PRODUCTO CONCENTRADO PROCEDENTE DEL EVAPORADOR, A UNA SECCION DE SOLIDIFICACION, PARA SU PROCESO ALLI CON EL PRODUCTO CONCENTRADO DE DICHO EVAPORADOR.
