软件简介

VMGSIM.V5.0.5 流程模拟

VMGSim 作为计算准确,功能强大以及高性价比的稳态流程模拟软
件,可以详细预测工艺装置和工厂的性能;无论是在新工艺装置的
设计,优化,还是在故障诊断等方面,VMGSim均能帮助工程师以提高
操作效率,改善产品质量,实现节省投资,降低操作费用,提高效
益,安全生产的目标。
在石油天然气,石油炼制,石油化工等领域,利用VMGSim你能够
准确建模并预测大多数的工艺装置的性能;
VMGSim在提高模拟模型的使用和开发效率方面有了新的创新:
集成了完全交互式流程模拟的最新技术;
工业级强大的热力学物性数据库和物性计算;
使用Visio, 窗体,脚本或网络浏览器进行图形化建模;
将大家所熟悉的Excel 作为一个单元操作或计算器而无缝嵌入
到你的VMGSim模型中;
模拟引擎:
在流程模拟单元,纯组分以及循环物流中,即便对于最大规模的模
型,VMGSim 都能够毫无限制地进行求解;你可以创建工艺模型,
并将模型存储为单元模板,以便在新的流程模型中进行调用;
VMGSim 的子流程架构允许你在任何嵌套次数的工艺流程方案中,
将模板以子流程的形式嵌入;
VMGSim 先进的高级计算技术是确保成功模拟你的工艺过程的理想
工具;VMGSim可以使你的模型简化: 它不再使用热循环流,也没有
必要在过程模型中包含不真实的物流,这是由于VMGSim在流程引
擎设计时采用了独特的端到端物流连接技术; VMGSim 可以在模型
中自动进行任何循环物流的计算,而不需要用户的干预;
与电子表格软件产品相近,用户输入VMGSim的任何信息都会被立
即处理;因此,模型的建立和优化同样迅速高效;

v5.0 (build 5, August 2009)
Dynamics
+ Released full dynamics engine


Oil Characterization
 Re-designed user interface
+ Allow renaming assays and blends
+ Cloning assays
+ Cloning oils
+ Specifying variables to adjust the names of the hypos (e.g. end up with MyBaseName_[123]F instead of OilName_AssayName_[123]F
+ Ability to re-cut blends (for example, useful if one would like to cut with [123]C instead of [123]F)
+ Visc Vs % Dist curves @ T, KinVisc Vs % Dist curves @ T, ThCond Vs % Dist curves @ T,
+ Visc Vs T curve, KinVisc Vs T curve, ThCond Vs T curve,
+ Content curves specification, inspecting them in streams and using them as specifications in towers
o More guiding messages as the assays are being built and also a more up to date log of actions and failures
o Interactively enable and disable Cut and Install buttons
+ Added reporting for oil


Fischer-Tropsch Reactor
+ Added a new Fischer-Tropsch Synthesis reactor unit operation

Unit operations
+ F-Type TEMA shell in exchanger rating
o Improved convergence of heat exchanger
+ Cross Connector now includes an option to automatically select  the variables to keep synchronized
+ Added Tc, Pc and GOR to special properties
x Fixes to pH variable from special properties
+ Added  an "Ions" tab to Amine Detail unit operation
x Improved convergence of tower when a water draw is close to zero flow
+ Added Cv and xT curves to Valves

Miscellaneous
 Allow multiple connections when connecting to input of controllers and selector blocks
+ Enabled right click menu "Copy Connection" to connect variables around flowsheet
+ Allow interconnection of variables that come from profiles
+ Allow addition of variables to Case Study from right click menu from unit operation forms
o Allow Case study to have the Min Value greater than the Max Value
+ Added a dedicated OutT variable to heater and cooler
x Fixed Excel 2007 problem in which cases would always resolve before saving
o Redesigned Options form to enhance functionality
+ Exposed a detailed list of properties per phase in the summary sets for equilibrium results of streams
o Enhanced convergence of controllers when they hit upper and lower boundaries
+ Added an option to controllers for users to define a "search direction" to aid in the convergence of difficult systems.
+ Added a comprehensive list of Alias names for refrigerants
+ Property package cloning now includes oil cases
+ New web based security system for licensing VMGSim
x Fixed problem in Excel unit operation to copy and paste plots
