化工专业英语-unit 7

第三部分化工原理一个工业催化过程的成功与否取决于原料成本、工序数、可操作性、反应条件等因素。

同时，一个成功的工业催化过程能够使催化剂的选择性和活性以及价格和寿命都达到适当的平衡。

而且，在21世纪，社会需要安全和环境友好型的生产工艺。

在将涉及催化剂的实验过程成功运用于商业生产时，有四个重要的工程因素起着至关重要的作用。

这些因素分别是反应器设计、操作条件、催化剂分离和再利用、原料预处理以及产物分离。

在这一部分内容中，我们将概述这些基本原理。

首先讨论表3-1中所列出的一个典型工艺装置中各个操作单元的功能、及该操作过程中所涉及的相态及其常规操作条件。

表3-1 单元操作及其功能和操作条件单元操作名称功能相态常规操作条件反应器(搅拌釜或管式反应器) 反应气-液-固, 气-固, 气-液, 或液-液0~20 MPa, 0~550 ºC蒸馏塔液体分离和提纯液态真空 1 MPa, -10~380ºC液-液萃取器溶质回收液态大气压, -10~100 ºC吸收塔气体分离和回收气-液大气压1 MPa, 20~100ºC吸附塔气体或液体的分离或回收气-固或液-固大气压 1 MPa, 20~200ºC结晶器从过饱和溶液中回收固体液-固大气压, -10~100 ºC过滤器/离心机固体回收液-固真空 2 MPa, -10~100ºC换热器冷却或加热液体气态或液态大气压0.5 MPa,-10~300 ºC冷凝器气体冷凝至液体气-液大气压1 MPa, -10~150ºC蒸发器/再沸器液体蒸发气-液大气压至 1 MPa,30~200 ºC第1章传质不同组分的两种物相开始接触时，组分间会发生从一相到另一相的质量传递，反之亦然。

这就是传质的物理基础。

面对均相混合物中组分的分离问题，工程师们常常利用混合物中各组分性质的不同来达到分离的目的。

通过检验混合物中各组分的物理化学性质来决定组分间哪些性质差别最大，因为性质差别越大，分离方法越经济可行。

It's not your conventional reaction to cheating. Not surprisingly, it has been a hit with many college students, just as it was with the plagiarists at Piper High. The student newspaper at Stanford ran an editorial attacking the use of antiplagiarism software as a potential violation of the school's honor code, which "prohibits professors from taking 'unusual and unreasonable precautions' in their academic procedures." Moreover, the paper said, checking for cheating "might even harm the relationship between students and faculty."参考译文：抄袭者成为了受害者，老师们成了压迫者。

Transportation, housing, clothing, communication, recreation, and food production —virtually every segment of our everyday lives is influenced to one degree or another by materials. Historically, the development and advancement of societies have been intimately tied to the members’ ability to produce and manipulate materi- als to fill their needs. In fact, early deep-seated根深蒂固的, 深层的civilizations have been designated by the level of their materials development (Stone Age, Bronze Age, Iron Age).The earliest humans had access to only a very limited number of materials, those that occur naturally: stone, wood, clay, skins, and so on. With time they discovered techniques for producing materials that had propertiessuperior to those of the natural ones; these new materials included pottery and various metals. Furthermore, it was discovered that the properties of a material could be altered by heat treatments and by the addition of other substances. At this point, materials utilization was totally a selection process that involved deciding from a given, rather limited set of materials the one best suited for an application by virtue of its characteristics.①It was not until relatively recent times that scientists came to understand the relationships between the structural elements of materials and their properties. This knowledge, acquired over approximately the past 100 years, has empowered them to fashion, to a large degree, the characteristics of materials. Thus, tens of thousands of different materials have evolved with rather specialized charac- teristics that meet the needs of our modern and complex society; these include metals, plastics, glasses, and fibers.The development of many technologies that make our existence so comfortable has been intimately associated with the accessibility of suitable materials. An advancement in the understanding of a material type is often the forerunner to the stepwise progression of a technology. For example, pottery // 陶器structural elements结构成分；property //.性能automobiles would not have been possibl- e without the availability of inexpensive steel or some other comparable substitute. In our contemporary era, sophisticated electronic devices rely on components that are made from what are called semiconducting materials.Materials Science and EngineeringThe discipline of materials science involves investigating the relationships that exist between the structures and properties of materials. In contrast, materials engineering is, on the basis of these structure–property correlations, designing or engineering the structure of a material to produce a predetermined set of properties.“Structure’’is at this point a nebulous term that deserves some explanation. In brief, the structure of a material usually relates to the arrangement of its internal components. Subatomic structure involves electrons within the individual atoms and interactions with their nuclei. On an atomic level, structure encompasses the organization of atoms or molecules relative to one another. The next larger structural realm, which contains large groups of atoms that are normally agglomerated together, is termed ‘‘microscopic,’’meaning that which is subject to direct observation using some type of microscope. Finally, structural elements that may be viewed with the naked eye are termed ‘‘macroscopic.’’The notion of ‘‘property’’ deserves elaboration. While in service use, all materials are exposed to external stimuli that evoke some type of response. stepwise//逐步的sophisticated//精制的，复杂的；semiconducting materials 半导体材料nebulous//含糊的，有歧义的subatomic//亚原子的microscopic//For example, a specimen subjected to forces will experience deformation; or a polished metal surface will reflect light. Property is a material trait in terms of the kind and magnitude of response to a specific imposed stimulus. Generally, definitions of properties are made independent of material shape and size.Virtually all important properties of solid materials may be grouped into six different categories: mechanical, electrical, thermal, magnetic, optical, and deteriorative. For each there is a characteristic type of stimulus capable of provoking different responses. Mechanical properties relate deformation to an applied load or force; examples include elastic modulus and strength. For electrical properties, such as electrical conductivity and dielectric constant, the stimulus is an electric field. The thermal behavior of solids can be represented in terms of heat capacity and thermal conductivity. Magnetic properties demonstrate the response of a material to the application of a magnetic field. For optical properties, the stimulus is electro- magnetic or light radiation; index of refraction and reflectivity are representative optical properties. Finally, deteriorative characteristics indicate the chemical reactivity of materials.In addition to structure and properties, two other important components are involved in the science and engineering of materials, viz. ‘‘processing’’and ‘‘performance.’’With regard to the relationships of these four components, the structure of a material will depend on how it is processed. 微观的// 宏观的deformation// 变形deteriorative//破坏（老化的）elastic modulus 弹性模量strength //强度；dielectric constant介电常数；heat capacity 热容量refraction。

它通常以七水结晶形式存在，很容易风化变为白色的一水合物粉末。

它也是人们熟知的家庭日用水软化剂。

碳酸钠有一种冷碱味，它可以从许多植物灰中提取出来。

大量的碳酸钠是用索尔韦法通过食盐来生产的。

用途生产玻璃是碳酸钠最重要的用途。

当碳酸钠与沙子和碳酸钙混合在一起，加热到很高的温度，然后快速冷却时，就产生了玻璃。

这类玻璃叫做钠钙玻璃。

碳酸钠在各种环境下也可以用作相对较强的碱。

例如，碳酸钠用作pH调节剂，以维持大多数显影剂反应所需的稳定的碱性条件。

它是市政水池常用的添加剂，用来中和氯的酸效应，提高pH值。

化学上，它常常用作电解质。

此外，与生成氯气的氯离子不同，碳酸根离子不腐蚀阳极。

它还可以用作酸碱滴定的基准物，因为它是空气中稳定存在的固体，容易准确称量。

生产索尔韦法：1861年比利时工业化学家，欧内斯特·索尔韦发明了一种方法，使用氨将氯化钠转化为碳酸钠。

索尔韦法是在一个大的空塔内进行的。

在塔底，碳酸钙（石灰石）被加热释放出二氧化碳。

CaCO3→ CaO + CO2在塔顶，氯化钠和氨的浓溶液进入塔内。

随着二氧化碳气泡穿过溶液，生成碳酸氢钠沉淀：NaCl + NH3 + CO2 + H2O → NaHCO3 + NH4Cl碳酸氢钠通过加热转化为碳酸钠，并释放出水和二氧化碳：2 NaHCO3→ Na2CO3 + H2O + CO2同时，通过加热氯化铵和石灰（氢氧化钙），可以重新制备氨。

Lesson 1Chemical Engineering1、What is chemical engineering and its content?The Institution of Chemical Engineers defines chemical engineering as “that branch of engineering which is concerned with processes in which materials undergo a required change in composition, energy content or physical state: with the means of processing; with the resulting products, and with their application to useful ends”.2、What concept is the landmark in the development of chemical engineering?Unit operations3、What are the basic laws of chemical engineering science?The principles of chemistry, physics, and mathematics.The laws of physical chemical and physics govern the practicability and efficiency of chemical engineering operations. Energy changes, deriving from thermodynamics consideration, are particularly important. Mathematics is a basic tool in optimization and modeling.4、Name the functions and branches of chemical engineering you know.Chemical Engineering Functions: The design and development of both processes and plant items.Branches of Chemical Engineering: Plastics, polymers, synthetic fibers, dyeing, pulp and paper manufactures, pharmaceutical industry, and separation of rare metals.Lesson 2 Chemical Equilibrium and Kinetics1、Which factors influence the reaction rates?a)Temperatureb)concentrations of reactants (or partial pressure of gaseous reactants)c)presence of a catalyst.2、How to determine the reaction equilibrium constants?For a reversible reaction：aA + bB = cC +dDthe equilibrium constant expression is written as follows:K = C c D d / A a B bLesson 3 The Second Law of Thermodynamics1、What are the applications of chemical thermodynamics?There is two major applications of thermodynamics:( i ) The calculation of heat and work effect associated with processes as well as the calculation of the maximum work obtainable from a process or the minimum work required to drive a process.( ii ) The establishment of relationship among the variables describing systems at equilibrium.Lesson 4 Chemical Reaction Engineering1、Homogeneous Reactions vs. Heterogeneous ReactionsHomogeneous reactions are those in which the reactants, products, and any catalyst used form one continuous phase; gaseous and liquid.Heterogeneous reactions are those in which two or more phases exist, and the overriding problem in the reactor design is to promote mass transfer between the phases. The possible combinations of phase are:( i ) Liquid-liquid ( ii ) Liquid-solid ( iii ) Liquid-solid-gas( iv ) Gas-solid ( v ) Gas-liquid2、Reactor Geometry(type)Stirred Tank ReactorsTubular ReactorsPacked Bed ReactorsFluidized Bed ReactorsLesson 5 Chlor-Alkali and Related Processes1、What are the mechanisms of chlor-alkali process?The reaction are based on the idea of using electrons as a reagent in chemical reactions. The basic reactions of brine electrolysis can be written as follows:Anode 2Cl- - 2e-—> Cl2Cathode 2H2O + 2e-—> H2 + 2OH-The overall reaction is: 2Na+ + 2Cl- + 2H2O —> NaOH + Cl2 + H2Lesson 7 Momentum, Heat, and Mass Transfer1、In some cases, momentum , heat and mass transfer all occurs simultaneously, explain with examples.In a water-cooling tower, where transfer of sensible heat (heat transfer) and evaporation (mass transfer) both take place from the surface of the water droplets. Momentum transfer take place between the water droplets and air.2、What will happen for two adjacent layers of fluid with different moving velocities?There will be a tendency for the faster moving layer to be retarded and the slower moving layer to be accelerated by virtue of the continuous passage of molecules in each direction. There will be a net transfer of momentum from the fast to the slow moving stream.Lesson 10 Gas Absorption1、There are three ways in which a large contact area can be established:1. The liquid is brought in contact with the gas in the form of thin films ( film scrubbers).2. The liquid is dispersed in the gas in the form of minute drops (spray scrubbers).3. The gas is dispersed in the liquid in the form of small bubbles (bubble scrubbers). All apparatus applied in gas absorption practice is based on one of these three principles or on a combination of them.Lesson 13 Filtration1、Which factors should be considered in the operation of filtration?a)The properties of the liquid , particularly its viscosity, density and corrosive properties.b)The nature of the solid - its particle size and shape, size distribution, and packing characteristics.c)The concentration of solids in suspension.d)The quality of material to be handled, and its value.e)Whether the valuable product is the solid, the fluid, or both.f)Whether it is necessary to wash the filtered solids.g)Whether very slight contamination caused by contact of the suspension or filtrate with the various components of the equipment is detrimental to the product.h)Whether the feed liquor may be heated.i)Whether any form of pretreatment would be helpful.2、Which factors will have a close relation with the rate of filtration?a) The drop in pressure from the feed to the far side of the filter medium.b) The area of the filtering surface.c) The viscosity of the filtrate,d) The resistance of the filter cake.e) The resistance of the filter medium and initial layers of cake.Lesson 15 Computer-Assisted Design of New Process1、Design for new processed proceed through at least three stagesConceptual Design: the generation of ideas for new processes (processed synthesis) and their translation into an initial design. This stage includes preliminary cost estimates to asses the potential profitability of the process, as well as analyses of process safety andenvironmental considerations.Final Design: a rigorous set of design calculations to specify all the significance details of a process,Detailed Design: preparation of engineering drawing and equipment lists needed for construction.TBC ...Lesson 16 Catalysis1、Catalytic reactions can be classified into three types:The most common is heterogeneous catalysis, in which the catalyst is a solid and the reactants and products are either gases or liquids. The second type is homogeneous catalysis, in which the reactants, products and catalyst are molecularly dispersed in a single phase, usually the liquid phase. The third type is enzyme catalysis.Lesson 18 Polymers and Polymerization Techniques1、There are five general methods of polymerization:( i ) Bulk (or mass) ( ii ) Solution ( iii ) Slurry (or precipitation)( iv ) Suspension(or dispersion) ( v) EmulsionFurther lesser-used methods include:( vi ) Interfacial ( vii ) Reaction injection moulding (RIM)( viii ) Reactive processing of molten polymers2、A polymerization process consists of three stages:( i ) Monomer preparation ( ii ) Polymerization ( iii ) Polymer recover。
