| Summary: | 碩士 === 國立高雄應用科技大學 === 化學工程與材料工程系碩士在職專班 === 106 === Along with the evolution of science and technology, the ability of computer computing has become more powerful and popular. As a chemical engineer, it is more important to learn to use such a convenient tool to solve chemical problems and make the process production more effective with less effort. The way to solve the problem is to use computer software to realize the “reproducibility” of the chemical process by computer computing and to restore the chemical process by mathematical method. Then, by means of computer aided calculation, the material balance, heat balance, equipment size estimation, hydraulic calculation, mass and energy analysis, economic value evaluation, and so on, are carried out in the chemical plant.
In this thesis, the chemical simulation software, Aspen Plus, is used to simulate the static chemical process of the equipment revamping cases. Using the opportunity to replace the new equipment, the thermal integration and operation evaluation of the revamping process are redesigned. Also, the Aspen Plus suite is carried out for the economic evaluation of the utility usage and equipment value.
The design results show that the use of the system operation parameters and equipment size simulated by Aspen Plus can effectively reduce the use of utility materials. Also, it is able to estimate the cost of the equipment and calculate the economic benefit of the cost recovery period.
