Abstract: Disclosed is a method for the removal of ammonia from the off-gas of a finishing section of a urea production plant. The method comprises contacting the off-gas with a solid adsorbent capable of physically adsorbing ammonia, particularly activated carbon or zeolite. Thereupon the solid adsorbent having ammonia adsorbed thereon is separated from the gas and regenerated by dissolving ammonia in an extraction liquid, preferably water. After separating the water from the solid adsorbent, the latter is re-used in the process.

Abstract: remoção de amônia na finalização de ureia. a presente invenção refere-se a um método para a remoção de amônia a partir do desprendimento de gás de uma seção de finalização de uma usina de produção de ureia. o método compreende colocar em contato o desprendimento de gás com um adsorvente sólido capaz de fisicamente adsorver a amônia, particularmente carvão ativado ou zeólito. logo a seguir, o adsorvente sólido tendo amônia nele adsorvida é separado do gás e regenerado mediante a dissolução de amônia em um líquido de extração, de preferência água. após a separação da água do adsorvente sólido, este último é reutilizado no processo.
