Abstract
Installation for treating an ammonium carbamate-containing solution at high temperature, having at least one pressure stage comprising a heating and decomposition device to decompose at least part of the ammonium carbamate present in the solution, at least one gas separator liquid to remove from the solution the gaseous mixture of ammonia, carbon dioxide and water released during the treatment, which is part of or related to said heating and decomposition device, and a condenser or absorber to transfer said gaseous mixture to the liquid state, in whose installation at least the surfaces of said apparatuses arranged to be in contact with a high temperature ammonium carbamate-containing solution are made of a nickel-free ferritic steel, consisting essentially of at least 25% by weight of chromium, from 0 to 3% by weight of molybdenum and with a combined content of c argon and nitrogen of not more than 0.035% by weight, the rest being iron.
