化工过程稳态模拟又称静态模拟或离线模拟（Steady State Simulation,off-line Simulation）。通常所说的化工过程模拟或流程模拟多指稳态模拟。它是根据化工过程的稳态数据,诸如物料的压力、温度、流量、组成和有关的工艺操作条件、工艺规定、产品规格以及一定的设备参数,如蒸馏塔的板数、进料位置等,采用适当的模拟软件,用计算机模拟实际的稳态生产过程,得出详细的物料平衡和热量平衡。其中包括人们最为关心的原材料消耗、公用工程消耗和产品、副产品的产量和质量等重要数据。简言之,化工过程模拟就是在计算机上“再现”实际的生产过程。由于这一“再现”
Steady state simulation of chemical process, also known as static simulation or off-line simulation (Steady State Simulation, off-line Simulation). The so-called chemical process simulation or process simulation multi-finger steady-state simulation. It is based on the steady state of chemical process data, such as the pressure of the material, temperature, flow, composition and related process operating conditions, process specifications, product specifications and certain equipment parameters such as the number of plates in the distillation column, feed position, Appropriate simulation software is used to simulate the actual steady-state production process with a computer to derive the detailed material balance and heat balance. These include important data that people are most concerned about, such as the consumption of raw materials, the consumption of utilities and the output and quality of products and by-products. In short, chemical process simulation is “reproducing” the actual production process on a computer. Because of this “reproduction”
