Chemical Process Industries Shreve Free DownloadA thermodynamic model of plutonium (IV) nitrate solutions. Plutonium nitrate solutions contain a large number of chemical species and they exhibit significant deviations from ideal behavior. Modeling this system is challenging. A model that includes all known chemical species and accounts for nonideal solution behavior could contain several hundred unknown parameters, but insufficient published data exists for evaluating large numbers of parameters. A practical model of plutonium nitrate solutions, therefore, must be a compromise between the number of chemical species included and the number of parameters that can be evaluated from available data. A practical model of acidic plutonium nitrate was developed. The model, which was based on an extended UNIQUAC–Debye–Hückel equation, captures the essential behavior of the system with a minimum number of chemical species. It is capable of representing the vapor–liquid equilibrium data for the nitric acid–water system, the activity of water in the plutonium nitrate- nitric acid–water system, the distribution of plutonium–nitrate complexes in aqueous nitric acid solution, and plutonium adsorption on an anion exchange resin. 爱问共享资料是爱问自主研发的资料共享平台,包含了千万网友上传的多种格式的文档,同时也提供海量资料的免费下载. • safety & environment • contact process • pump types • seal materials • seal types • barrier system • seal locations • acid applications.
