I’d like to ask everyone~ The results are abnormal when simulating the absorption of a mixture of ammonia and carbon dioxide
Thread Content
Dear seniors, what does this message mean? Thank you very much. Initial enthalpy calculations were completed, with simulation warnings for the following stream: GASIN. The following messages were displayed during the calculations: * WARNING WHILE PERFORMING INITIAL ENTHALPY CALCULATIONS FOR STREAM: ‘GASIN’. Liquid-phase calculations were requested for a mixture in which all components are defined as Henry components (‘GLOBAL’), yet at least one of them is sub-critical (‘NH3’). The flash calculations may be incorrect. – This article is from **Chemical Engineering – Making chemical engineering techniques accessible to everyone; original URL: https://bbs.mahoupao.com/thread-217946-1-1.html
The hint indicates that NH3 is in a subcritical state under the given conditions, and it may be incorrect to treat it as a Henry gas. Is it possible to not use NH3 as a Henry gas?
Hello, senior! Thank you for your answer this time! My simulated operating conditions are 35°C at normal pressure; if the Henry’s law component is not considered, wouldn’t ammonia be unable to be absorbed?
The pressure is 101.325 kPa
Is it because the thermodynamic model chosen wasn’t good?~
