[求助] 急!!!化工英语翻译,O(∩_∩)O谢谢

本文以乙醇分离物系的精制过程为研究背景,首先依据该物系的物性特点,选用UNIQUAC-RK物性计算方法进行该物系的工艺流程模拟计算,而后通过分析由Aspen plus软件得出的剩余曲线图,确定了该物系的精馏工艺流程。采用模拟软件对乙醇分离物系进行精馏工艺流程模拟,提出精馏实验方案,根据此方案开展精馏实验,得到相应的实验结果。采用模拟软件对乙醇分离物系精馏实验进行模拟拟合,以验证物性计算方法的可靠性,而后依据模拟优化步骤对该物系精馏装置操作参数进行灵敏度分析,确定了较优的操作参数。根据模拟优化结果,设计乙醇分离物系精馏装置,采用高效填料和合理的塔内构件。为更深入开展这方面的研究和工业应用积累了必要的实验数据与理论基础。

This article used refined production of ethanol dissociation system as research background. First, according to its physical features, it used UNIQUAC-RK property calculation method to simulate calculation of process flow of this system and then analyzed the remnant curve from Aspen plus software to determine its refined process flow. It adopted simulation software to simulate refined process flow on the ethanol dissociation system, set up refine experiment protocol, processed refine experiment according to this protocol, and obtained corresponding experiment result. Then it adopted simulation software to simulate refine experiment of ethanol dissociation system to check the reliability of property calculation method and analyzed the agility of this system refine set operation parameters according to simulation optimization steps to determine relatively good operation parameters. According to simulation optimization result, the ethanol dissociation system refine set is designed and it used efficient loading and proper internal tower structure. This provided necessary experiment data and theoretical base for deep research and industrial application of this field.
