Abstract
La presente invención se refiere a método para la producción de urea y amoníaco, el cual consiste en: separar una corriente gaseosa que comprende dióxido de carbono, hidrógeno y nitrógeno, en dos porciones, primera y segunda; remover cuando menos parcialmente dióxido de carbono de la primera porción de la corriente gaseosa y mezclar la corriente resultante con la segunda porción de la corriente gaseosa; alimentar la corriente resultante a un reactor que contiene una solución de amoníaco acuosa, en donde el dióxido de carbono y el amoníaco reaccionan para formar una solución de carbamato de amonio; alimentar la solución de carbamato de amonio a un sintetizador de urea, en donde la urea se forma a partir de la solución ; y alimentar la corriente gaseosa del reactor a un sintetizador de amoníaco, en donde el hidrógeno y nitrógeno en la corriente del reactor forman amoníaco que es subsecuentemente absorbido en agua para formar una solución de amoníaco acuosa, una porción de la cual se recircula el reactor para que reaccione con el dióxido de carbono de la corriente gaseosa y otra porción de la cual se somete a destilación para recuperar amoníaco líquido.The present invention relates to a method for the production of urea and ammonia, which consists of: separating a gas stream comprising carbon dioxide, hydrogen and nitrogen into two parts, first and second; remove at least partially carbon dioxide from the first portion of the gas stream and mix the resulting stream with the second portion of the gas stream; feeding the resulting stream to a reactor containing an aqueous ammonia solution, where carbon dioxide and ammonia react to form an ammonium carbamate solution; feeding the ammonium carbamate solution to a urea synthesizer, where urea is formed from the solution; and feeding the gaseous stream from the reactor to an ammonia synthesizer, where the hydrogen and nitrogen in the reactor stream form ammonia which is subsequently absorbed in water to form a solution of aqueous ammonia, a portion of which the reactor is recirculated to it reacts with carbon dioxide from the gas stream and another portion of which is subjected to distillation to recover liquid ammonia.
