课程名称：蒸馏塔：原理、操作与设计 概述：如今，石油精炼、石化、化工和过程工业中普遍用到各种设计和应用的蒸馏塔。本课程旨在让您全面理解蒸馏塔的构造细节与功能，这对于成功运营您的工厂至关重要。课程包含五个主要内容： 1. **蒸汽-液体平衡**： - 纯组分和复杂混合物的热力学 - 纯组分的挥发性：沸点、蒸气压 - 感热与潜热的概念 - 混合物在蒸馏中的表现：露点与泡点、蒸发曲线、全/部分冷凝与蒸发、液-气分离及组分根据挥发性分布的关系 - 温度、压力与馏分和残余组分组成之间的关系 2. **工业蒸馏实践**： - 工业蒸馏塔的操作参数（压力、温度、流量、回流比等） - 分离能力：级数、液体和蒸气流量、进料位置 - 塔内压力控制和压力分布 - 内部流量、浓度和温度分布、浓度峰值 - 物质和热量平衡的概念，分离质量和分馏能力 - 冷凝器和再沸器的热量负担、回流与蒸发比及工业配置 - 过程控制回路和仪器 3. **工业蒸馏设备**： - 塔板：技术、性能、灵活性 - 填料（结构型或随机型）：技术、性能、灵活性 - 不同类型的接触系统：泡帽、固定或浮动阀 - 液体或蒸气分布器、收集器和再分配器 - 常见问题：洪水、渗漏、污垢等 4. **利用ASPEN PLUS评估蒸馏塔性能**： - 基本情况 - 温度、压力、进料位置、回流比的影响 5. **案例研究**： - 乙烯/乙烷分馏装置 - 再沸器操作 - 闪蒸分离器 - 蒸馏塔顶操作 - 去丙烯处理案例研究 本课程中包含许多图像、截面视图、图表及动画，极大地增强了其作为教育工具和工业参考资料的价值。它不仅对在蒸馏过程中需要掌握相关知识的工程师和操作员有重要意义，同时也是过程、化学、石化及石油工程学科本科生的学习指南。 欢迎查看免费预览视频与课程大纲，期待在课程的第一部分与您见面！希望能与您一起拓展知识的翅膀。
Distillation columns of various designs and applications are encountered nowadays throughout petroleum refining, petrochemical, chemical and process industries.This course is designed to provide you with a complete understanding of construction details and functioning of distilling columns. This understanding is a prerequisite for successful operation of your plant.The course features 5 major items:1- VAPOR LIQUID EQUILIBRIA: (thermodynamics of pure components and complex mixtures)Volatility of pure components: boiling point, vapor pressureConcept of Sensible and Latent HeatBehavior of mixtures in distillation: dew and bubble points, vaporization curves, total/partial condensation and vaporization, liquid-vapor separation and distribution of components according to their volatilityRelation between temperature, pressure and composition of distillate and residue...2- INDUSTRIAL DISTILLATION PRACTICES:Operating parameters of an industrial distillation column (Pressure, Temperature, Flow rates, Reflux Ratio...)Separating power: number of stages, liquid and vapor traffics, feed inlet locationColumn pressure: pressure control and pressure profile along the columnInternal flow rates profiles, concentration and temperature profiles, concentration peaksMaterial balance of the column: concepts of cut point, separation quality and fractionation capabilityHeat balance: condenser and reboiler duties, Reflux and Boil-up ratios and industrial configurationsInstrumentation and process control loops around the column...3- INDUSTRIAL DISTILLATION EQUIPMENT:Trays: technology, performances, flexibilityPackings (structured or random): technology, performances, flexibilityDifferent types of contacting systems for the active area: bubble caps, fixed or floating valvesLiquid or vapor distributors, collectors and redistributorsTroubles such as flooding, weeping, fouling......4- ASSESSING DISTILLING COLUMN PERFORMANCE USING ASPEN PLUS (A CHEMICAL ENGINEERING SIMULATOR)Base caseEffect of temperatureEffect of pressureEffect of feed stage locationEffect of reflux ratio...5- SOLVED PROBLEMSEthylene / Ethane fractionatorReboiler operationFlash separatorDistilling column overhead operationsDepropanizer case study...Many images, cross sectional views, graphs and animations can be found throughout, increasing the value of this course as an educational tool and industrial reference for personnel involved in distilling operations.So this course is not only of use to practicing engineers and operators to whom a knowledge of the distillation process is of crucial importance in efficient operation of distilling columns but also intended as a study guide for undergraduates in process, chemical, petrochemical & petroleum engineering disciplines.So with no further ado, check out the free preview videos and the curriculum of the course and we look forward to seeing you in the first section.Hope to see you there!WR TrainingSpread the wings of your knowledge
