化学工程与工艺专业英语课文翻译
化学工程与工艺专业英语课文翻译Chemical Engineering and Process TechnologyChemical engineering is a branch of engineering that applies physical sciences (physics and chemistry) and life sciences (biology, microbiology, biochemistry) togetherwith mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy. It essentially deals with the design and operation ofplants and equipment for performing chemical reactions onan industrial scale.Chemical engineers are responsible for the development and production of a diverse range of products, such as fuels, pharmaceuticals, food and drink, and plastics. They also work in a variety of industries, including oil and gas, water treatment, and environmental management.The field of chemical engineering is constantly evolving, with new technologies and processes beingdeveloped to improve efficiency and sustainability. This requires chemical engineers to stay up-to-date with the latest developments in their field and to continually adapt their skills and knowledge.Process technology, on the other hand, focuses on the methods and techniques used to transform raw materials into useful products. This includes the design, operation, and optimization of chemical, physical, and biological processes. Process technologists work closely with chemical engineers to ensure that the processes are efficient, safe, and environmentally friendly.Some of the key areas of study within chemical engineering and process technology include thermodynamics, fluid mechanics, heat transfer, mass transfer, reaction kinetics, process control, and process design. These subjects form the foundation of the discipline and are essential for understanding and solving the complex problems that chemical engineers and process technologists face in their work.In recent years, there has been a growing emphasis on sustainability and green engineering within the field of chemical engineering and process technology. This has led to the development of new processes and technologies that minimize waste, reduce energy consumption, and limit the environmental impact of chemical production.One example of this is the use of renewable feedstocks, such as biomass, in place of traditional fossil fuels. By utilizing sustainable raw materials, chemical engineers and process technologists can help to reduce the reliance on finite resources and decrease the carbon footprint of chemical processes.Another important development in the field is the use of process intensification, which involves the integration of multiple processes into a single, more efficient system. This approach can lead to significant improvements in productivity, energy efficiency, and cost savings.As the demand for chemical products continues to grow, the role of chemical engineers and process technologists inaddressing global challenges, such as climate change and resource depletion, becomes increasingly important. By applying their knowledge and skills to develop innovative and sustainable solutions, they can help to create a more environmentally friendly and economically viable future.In conclusion, chemical engineering and process technology are dynamic and interdisciplinary fields that play a crucial role in the production of a wide range of products. With a focus on sustainability and innovation, chemical engineers and process technologists are well-positioned to address the challenges of the 21st century and contribute to the development of a more sustainable and prosperous world.。

化学工程与工艺专业英语
化学工程与工艺专业英语1. Although the use of chemicals dates back to the ancient civilizations, the evolution of what we know as the modern chemical industry started much more recently. It may be considered to have begun during the Industrial Revolution, about 1800, and developed to provide chemicals roe use by other industries.尽管化学品的使用可以追溯到古代文明时代,我们所谓的现代化学工业的发展却是非常近代(才开始的)。
可以认为它起源于工业革命其间,大约在1800年,并发展成为为其它工业部门提供化学原料的产业.2.At the start of the twentieth century the emphasis on research on the applied aspects of chemistry in Germany had paid off handsomely, and by 1914 had resulted in the German chemical industry having 75% of the world market in chemicals. This was based on the discovery of new dyestuffs plus the development of both the contact process for sulphuric acid and the Haber process for ammonia. The later required a major technological breakthrough that of being able to carry out chemical reactions under conditions of very high pressure for the first time.20世纪初,德国花费大量资金用于实用化学方面的重点研究,到1914年,德国的化学工业在世界化学产品市场上占有75%的份额。

Unit 6 Chlor-Alkali and Related Processes氯碱及其相关过程纵观历史,大众化学品工业在氯碱及其相关过程之上。
该部分通常包括氯气、苛性苏打(氢氧化钠)无水碳酸钠(以各种形式存在的碳酸钠的衍生物),以及以石灰为基础的产品。
自从无水碳酸钠和氢氧化钠的各种制备工艺发现以来,两者在作为碱为主要原料方面相互竞争。
电解过程的特殊经济性意味着不管对氯气和氢氧化钠这两种不同类型的产品的相对需求量如何,你只有以固定的比例同时制备氯气和氢氧化钠。
这引起了氢氧化钠的价格的摇摆不定,从而使得纯碱作为一种碱或多或少有利。
氯气苛性苏打和纯碱的生产都取决于廉价易得的原料供应,前者的生产需要廉价的海水和电力的供应,而纯碱的生产需要海水、石灰和大量的能耗。
纯碱厂只有在其原料不必要长距离的运输时才能赢利。
这些原料供应利用是影响化工企业位臵分布的一个重要因素。
1. 石灰为基础的产品一种关键(重要)原料是石灰石。
石灰石主要是由CaCO3 组成,高质量的石灰石可直接用于下一步反应。
石灰石通常在大型露天石矿中开采,许多采石矿也进行原料的一些处理。
从石灰石得到两种重要的产物:生石灰(CaO)和熟石灰水,生石灰是由石灰石根据该反应是热分解(1200-1500℃)制备得到。
CaCO3 —— >CaO+ CO2一般的,石灰石经过粉碎加入倾斜旋转窑的较高端,在此发生热分解反应,生石灰在另一端回收。
然而,通常生石灰用于进一步反应而分离,而加入其它化合物,与生石灰在窑的较低口处生成最低产品。
例如,加入铝矿、铁矿和沙石可生成硅酸盐水泥。
纯碱的生产,通常要向生石灰加入焦炭,焦炭燃烧生成纯碱所需的CO2,熟石灰由生石灰和水的反应制造,较生石灰更加方便。

Unit 1 Chemical Industry化学工业1.Origins of the Chemical IndustryAlthough the use of chemicals dates back to the ancient civilizations, the evolution of what we know as the modern chemical industry started much more recently. It may be considered to have begun during the Industrial Revolution, about 1800, and developed to provide chemicals roe use by other industries. Examples are alkali for soapmaking, bleaching powder for cotton, and silica and sodium carbonate for glassmaking. It will be noted that these are all inorganic chemicals. The organic chemicals industry started in the 1860s with the exploitation of William Henry Perkin’s discovery if the first synthetic dyestuff—mauve. At the start of the twentieth century the emphasis on research on the applied aspects of chemistry in Germany had paid off handsomely, and by 1914 had resulted in the German chemical industry having 75% of the world market in chemicals. This was based on the discovery of new dyestuffs plus the development of both the contact process for sulphuric acid and the Haber process for ammonia. The later required a major technological breakthrough that of being able to carry out chemical reactions under conditions of very high pressure for the first time. The experience gained with this was to stand Germany in good stead, particularly with the rapidly increased demand for nitrogen-based compounds (ammonium salts for fertilizers and nitric acid for explosives manufacture) with the outbreak of world warⅠin 1914. This initiated profound changes which continued during the inter-war years (1918-1939).1.化学工业的起源尽管化学品的使用可以追溯到古代文明时代,我们所谓的现代化学工业的发展却是非常近代(才开始的)。

我们马上可以看到,它的内容变化很大。
我们首先了解或先感觉一下这个词的含义。
尽管研究和开发的定义总是分得不很清楚,而且有许多重叠的部分,我们还是要试着把它们区分开来。
简单说来,研究是产生新思想和新知识的活动,而开发则是把这些思想贯彻到实践中得到新工艺和新产品的行为。
可以用一个例子来描述这一点,预测一个有特殊生物活性的分子结构并合成它可以看成是研究而测试它并把它发展到可以作为一种新药推向市场这一阶段则看作开发部分。
1.Fundamental Research and Applied ResearchIn industry the primary reason for carting out R&D is economic and is to strengthen and improve the company‟s position and profitability. The purpose of R&D is to generate and provide information and knowledge to reduce uncertainty, solve problems and to provide better data on which management can base decisions. Specific projects cover a wide range of activities and time scales, from a few months to 20 years.1.基础研究和应用研究在工业上进行研究和开发最主要的原因是经济利益方面,是为了加强公司的地位,提高公司的利润。
R&D的目的是做出并提供信息和知识以减低不确定性,解决问题,以及向管理层提供更好的数据以便他们能据此做出决定。
特别的项目涵盖很大的活动范围和时间范围,从几个月到20年。
We can pick out a number of areas of R&D activity in the following paragraphs but if we were to start with those which were to spring to the mind of the academic, rather than the industrial, chemist then these would be basic, fundamental (background) or exploratory research and the synthesis of new compounds. This is also labeled “blue skies” research.我们可以在后面的段落里举出大量的R&D活动。
但是如果我们举出的点子来源于研究院而不是工业化学家的头脑,这就是基础的或探索性的研究Fundamental research is typically associated with university research. It may be carried out for its own intrinsic interest and it will add to the total knowledge base but no immediate applications of it in the “real world” well be apparent. Note that it will provide a valuabletraining in defining and solving problems, i.e. research methodology for the research student who carries it out under supervision. However, later “spin offs” from such work can lead t o useful applications. Thus physicists claim that but for the study and development of quantum theory we might not have had computers and nuclear power. However, to take a specifically chemical example, general studies on a broad area such as hydrocarbon oxidation might provide information which would be useful in more specific areas such as cyclohexane oxidation for the production of nylon intermediates.基础研究通常与大学研究联系在一起,它可能是由于对其内在的兴趣而进行研究并且这种研究能够拓宽知识范围,但在现实世界中的直接应用可能性是很小的。
请注意,这种以内就在提出和解决问题方面提供了极有价值的训练,比如,在指导下完成研究工作的学生所接受的研究方法学(的训练)。
而且,从这些工作中产生的“有用的副产品”随后也能带来可观的使用价值。
因此,物理学家宣称要不是量子理论的研究和发展我们可能仍然没有计算机和核能量。
不管怎样,举一个特殊的化学方面的例子吧,在各个领域如烃的氧化方面所做的广泛的研究将为一些特殊的领域如环己烯氧化生成尼龙中间产物提供有用的信息。
Aspects of synthesis could involve either developing new, more specific reagents for controlling particular functional group interconversions, i.e. developing synthetic methodology or complete synthesis of an entirely new molecule which is biologically active. Although the former is clearly fundamental the latter encompasses both this and applied aspects. This term …applied‟ has traditionally been more associated with research out in industrial laboratories, since this is more focused or targeted. It is a consequence of the work being business driven.通过合成可以生产出一些新的、更特殊的试剂以控制特殊的官能团转换,即发展合成方法或完成一些具有生物活性的新分子的合成。
尽管前者显然属于基础性研究而后者则包括基础研究和实用性研究两部分。
所谓“实用性”习惯上是指与在工业实验室完成的研究联系在一起的,因为它更具目的性,它是商业行为驱动的结果。
Note, however, that there has been a major change in recent years as academic institutions have increasingly turned to industry for research funding, with the result that much more of their research effort is mow devoted to more applied research. Even so, in academia the emphasis generally is very much on the research rather than the development.然而,请注意。
