Abstract: 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.
