摘要： In some embodiments, the disclosure is directed to a system for simulating multiple components and phases for fluid phase detection. In some embodiments, the system is configured to execute fast iterations under given temperature, pressure, and feed, with liquid phases starting from 100% purity of a corresponding key component. In some embodiments, the system is configured to apply a direct substitution method with relaxation damping for iterations at fixed conditions. In some embodiments, the system is configured to draw a tangent plane from a suspicious phase composition and execute a tangent plane distance analysis at a potentially missed physical phase by estimating 95% to 99.9999% purity of a possible liquid key component. In some embodiments, the system is configured to automatically correct the order of key components for simulations, based on analyses such as tangent plane distance analysis, immiscibility checks, and the exclusion of Henry components.

摘要： Simulation of process control environments, including dynamic properties, with a modified first-order Taylor series expansion. By using more linear calculations, a physical dynamic property is approximated in less time and with fewer computing resources. By adjusting the approximation to introduce curvature, a physical dynamic property is represented over a wider range than with basic linear series expansions. A comparison to a basic linear first-order series expansion identifies conditions when a rigorous update of a dynamic property is needed.
