Energy Management and Process Improvement of Methanol Production
A heat exchanger network (HEN) for the process of methanol synthesis has been studied by combination of pinch design method and the application of “Twisted Tube” heat exchanger units as a new technology. The HEN is reconstructed based on the full utilization of maximum allowable pressure drops for the process hot and cold streams. An algorithm is developed to generate design procedure for twist...
متن کاملExergy and Energy Analysis of Effective Utilization of Carbon Dioxide in the Gas-to-Methanol Process
Two process models are used to convert carbon dioxide into methanol. These processes have been extended and improved using Aspen Plus simulator software. Both processes are found in the CO2 correction system. In this machine, the desired synthesis gas is produced in a flexible configuration. At the same time, the conversion of CO2 to hydrogen via a copper-based catalyst ha...
متن کاملUpcycling wastes with biogas production: An exergy and economic analysis
The massive consumption of finite resources creates high economical and environmental costs due to material dispersion and waste generation. In order to overcome this, by-products and wastes may be used, to avoid the use of virgin materials and benefit from the useful inherent energy of the material. By adding value to the material, economic and environmental performance can be improve, which i...
متن کاملApplication of Exergy Analysis and Response Surface Methodology (RSM) for Reduction of Exergy Loss in Acetic Acid Production Process
Exergy analysis and response surface methodology (RSM) is applied to reduce the exergy loss and improve energy and exergy efficiency of acetic acid production plant. Exergy analysis is run as a thermodynamic tool to assess exergy loss in reactor and towers of acetic acid production process. The process is simulated in Aspen Plus(v.8.4) simulator and the necessary thermodynamics data for calcula...
متن کاملEvaluation of an Integrated Cryogenic Natural Gas Process with the Aid of Advanced Exergy and Exergoeconomic Analyses
In this study, an integrated structure of the air separation unit, natural gas liquids recovery equipped with nitrogen removal unit is developed. In this regard, advanced exergy and exergoeconomic analyses are used to examine the irreversibility, possible improvements and the cost of the inefficiencies of the process. The exergy analysis presents information on the origin of the irreversibility...
