Please help explain the composition and properties of the first and second liquids, thank you! This post was last edited by Boating Five Lakes on 2009-3-9 11:54 ]
“"First A liquid and second A liquid" are mainly abbreviations for the methane ammonium liquid recovered from the first and second stage absorption systems in the aqueous urea process unit. Their compositions are respectively:: A liquid: CO2 is 32.5%, NH3 is 41.5%, H2O is 26% ； dimethyl liquid: CO2 is 18%, NH3 is 34%, and H2O is 47%.
Thank you to the heroes on the second floor! Could you please explain the toxicity of the primary and secondary liquids, their corrosivity to the container (high, medium, low) and whether they cause scaling? Thanks!
Could you please help me explain the toxicity of the first and second liquids, their corrosiveness to the container (high, medium, low) and the degree of scaling? Thank you!
Let me throw some light on things. Both the first and second liquids are toxic and can cause ammonia suffocation. The toxicity you are talking about refers to corrosiveness. Simply put, the corrosiveness of the first liquid is directly proportional to the concentration. The first liquid has a higher concentration than the second liquid. The requirements for equipment and piping are stainless steel. As for scaling, neither the first-grade liquid nor the second-grade liquid has scaling characteristics. The scaling is caused by the introduction of other media such as oil during the production process. Experts please continue! This post was last edited by Boating Five Lakes on 2009-3-18 10:10 ]
