Theoretical models of chemical process

WebbIn modern chemical industry processes, modeling and simulation are a crucial pillar of day-to-day operations from design to maintenance and control of chemical process technologies. Today, the modeling task in the chemical industry often requires dynamic process modeling and simulation to follow the transient behavior of the system. WebbProcess simulation is a model-based representation of chemical, physical, biological, and other technical processes and unit operations in software [43]. Heat and material balance (HMB) equations are used in HYSYS for simulation. The specific algorithm is needed to solve equations of conservation of mass and energy.
