Abstract

EL CUAL COMPRENDE LA DESHIDRATACION CATALITICA DE FORMAMIDA GASEOSA EN UN REACTOR TUBULAR, EN EL QUE LA FORMAMIDA GASEOSA, QUE HA SIDO CALENTADA A TEMPERATURAS QUE VAN DE 330ºC A 400 ºC, ES CONDUCIDAAL REACTOR TUBULAR PARA FORMAR UN GAS DE PROCESO QUE CONTIENE ACIDO CIANHIDRICO GASEOSO, AGUA Y FORMAMIDA QUE NO HA REACCIONADO, EN EL QUE LA TEMPERATURA DEL GAS DE PROCESO AUMENTA A LO LARGO DEL REACTOR TUBULAR EN 0,25 HASTA 0,75 K/cm. EL PROCEDIMIENTO SE LLEVA A CABO TENIENDO EL GAS EN EL REACTOR UNA TEMPERATURA QUE VA DE 330 ºC A 600 ºC; DONDE EL REACTOR ES CALENTADO MEDIANTE EL GAS DE ESCAPE CALIENTE PROCEDENTE DE UN QUEMADOR DE GAS NATURAL Y CONDUCIDO EN LA MISMA CORRIENTE QUE EL GAS DE PROCESO. ADEMAS, EL PROCEDIMIENTO SE LLEVA A CABO A UNA PRESION QUE VA DE 70 A 350 mbar EN UN REACTOR MULTITUBULARWHICH INCLUDES THE CATALYTIC DEHYDRATION OF GASEOUS FORMAMIDE IN A TUBULAR REACTOR, IN WHICH THE GASEOUS FORMAMIDE, WHICH HAS BEEN HEATED TO TEMPERATURES VARING FROM 330ºC TO 400ºC, IS CONDUCTED TO THE TUBULAR REACTOR TO FORM A GASEOUS GAS TO FORM A GAS OF GASEOUS CIENOS , WATER AND FORMAMIDE THAT HAS NOT REACTED, IN WHICH THE TEMPERATURE OF THE PROCESS GAS INCREASES THROUGHOUT THE TUBULAR REACTOR BY 0.25 TO 0.75 K / cm. THE PROCEDURE IS CARRIED OUT HAVING THE GAS IN THE REACTOR A TEMPERATURE RANKING FROM 330 ºC TO 600 ºC; WHERE THE REACTOR IS HEATED USING THE HOT EXHAUST GAS FROM A NATURAL GAS BURNER AND CONDUCTED IN THE SAME CURRENT AS THE PROCESS GAS. ALSO, THE PROCEDURE IS CARRIED OUT AT A PRESSURE VARING FROM 70 TO 350 mbar IN A MULTITUBULAR REACTOR
