Design and performance simulation of multi-stream, plate-fin heat exchangers. 中油奥特科技有限公司自2003年起即负责Aspen Plate Fin Exchanger软件在国内的推广和销售，全面负责Aspen Plate Fin Exchanger软件在中国的推广、培训和技术支持。
(1)计算模式
- 设计：根据各流股的工艺条件，用简捷法计算出冷箱的几何尺寸及通道层数
- 核算：给定进出口状态，核算换热器
- 模拟：给定冷箱的几何尺寸、通道层数及进口状态，计算出口状态
(2)流道分配模拟：
- 计算给定冷箱每一流道的操作特性（最大流道数可达 240 ）。可预测冷箱的横断面翅片温度分布，从而可对各种流道分配方案进行研究。
(3)热虹吸式冷箱计算，流股分配方案分析及并流、错流分析
(4)冷箱类型
- 冷箱最大流股数可达 15 股。流股之间换热形式可采取逆流、并流、错流。单一冷箱或多个单元串、并组合的复合冷箱，这些冷箱可以垂直式或水平式。热虹吸式冷箱可以是内置式（内潜在液室中）或外置式（通过管道和塔底的液室连在一起）。
(5)分配器的类型
- 分配器可以计算进口和出口分配器的扩张压降，可以检查流量分布是否均匀，再分配器有合并型、分支型、也可部分流股抽出。
(6)翅片特性数据
- 可以通过输入界面人工输入翅片的传热及压降特性数据（平直、多孔、波纹 / 人字型、锯齿、片条），若没有厂家数据，可根据软件内部的特性曲线求出翅片特性。由于深入及独特的研究工作， HTFS 对处理翅片通道的沸腾和冷凝流体流动有独特的方法。
(7)程序组成
- PFIN—— 简捷计算：首次计算板翅式换热器时首先用它计算换热器的基本尺寸
- MUSE—— 标准计算：按标流道分布计算换热器
- MULE—— 流道分布校正及手工进行流道分布
- MUSC—— 错流校正
Aspen MUSE performs a detailed simulation of multi-stream, plate-fin heat exchangers made from brazed aluminum, stainless steel, or titanium. It can be used standalone by the thermal specialist for exchanger design or as an integrated product with AspenTech's steady-state process simulation program, Aspen HYSYS. Aspen MUSE is a core element of AspenTech's aspenONE Process Engineering applications.
Features
- Research Based Correlations : Provides models and correlations based on more than 35 years of Aspen HTFS proprietary research, assuring users of reliable designs.
- Design Mode : Calculates the geometry for a given set of process inlet and outlet conditions.
- Simulation Mode : Calculates the outlet conditions and performance of a given exchanger from specified inlet conditions.
- Layer Simulation : Calculates the performance of every layer in a given exchanger from specified inlet conditions. The metal temperatures across the exchanger are also predicted to enable an assessment of the layer patterns.
- Up to 20 Process Streams : Up to 20 process streams in co-current, counter-current, or crossflow with any complexity of exchanger inlet and outlet geometry.
- Single Phase, Boiling and Condensing
- Physical Properties : Specify fluid physical properties, import them from a process simulator, or get MUSE to calculate them using the Aspen COMThermo? properties package.
- Exchanger Diagrams : Provides guidance for input data review.
- Integrated with Aspen HYSYS : High-level runtime integration enables engineers to rigorously model heat exchanger operation within the context of the overall process.
Benefits
- Improved Design : Ideal for manufacturers, engineering companies, and owner operators that require a robust, flexible program with accurate heat transfer and pressure drop methods. Aspen MUSE provides this in a unique commercial package supported by authoritative research-based methods and validation.
- Improved Process Operations : Rigorous simulation of multi-stream, plate-fin units allows process engineers to optimize performance of LNG, ethylene, and air separation plants.
- Increased Engineering Efficiency : Internationally accepted Aspen MUSE simulations can be used to evaluate vendor plate-fin designs with confidence.
