METHOD FOR THE PRODUCTION OF UREA

摘要

A method for the production of synthesis urea from liquid ammonia and gaseous carbon dioxide, comprising the step of feeding separate flows (6, 8) of liquid ammonia and gaseous carbon dioxide in continuous to a substantially vertical or horizontal column synthesis reactor (1), is distinguished in that the feed of liquid ammonia is split up into at least two consecutive sections (Z1-Z7) of said column.
