摘要: 香兰素是最早合成的香料品种之一，全球香兰素年总产量近两万吨。中国是世界香兰素出口大国，其中一半以上用于出口。香兰素的合成方法有很多种。本文通过研究香兰素的产品特性及其国内外市场动态，分析其产品的市场意义与价值。同时本文介绍了工业上数种香兰素的合成方法，从合成香兰素的各种路线中，主要分析以愈创木酚为原料合成香兰素的工艺路线。79856

以某工厂的操作数据为设计依据，根据质量守恒原则，通过物料衡算，计算出原料与产品之间的定量关系，由此确定产出定量的成品所需原料、辅助材料的用量；通过物料衡算，还可以算出各种中间产品、副产品、成品的产量和三废的排放量，以及生产过程中各个阶段的原料和辅助材料的损耗量及其组成。在物料衡算的基础上进一步进行设备工艺计算及进行设备选型。物料衡算和设备计算结束后就可以进行热量衡算。热量衡算的依据是能量守恒定律，即输入设备操作的能量等于操作后输出的能量。

在生产过程中，物料会计和设备建模和主要尺寸确定车间的完成后，工厂可以开始布局设计工作。 工厂布局的主要任务是安排工厂的平面结构，内部组成，生产设备，仪器的电气设置等设施。 其设计符合生产过程的要求，经济实用。 厂房布局合理或不重要，直接影响到建设项目投资，运行后维护安全，经济指标完成情况。 因此，要求技术人员掌握整体情况，整体考虑等相关人员做好店铺布局设计。

Study on process design of 100 tons of vanillin

Abstract: Vanillin is one of the earliest synthetic spice varieties, the global total output of vanillin nearly 20,000 tons。 China is the world's vanillin export country, of which more than half for export。 There are many ways to synthesize vanillin。 This paper analyzes the product characteristics of vanillin and its domestic and international market dynamics, and analyzes the market significance and value of its products。 At the same time, this paper introduces the synthesis method of several vanillin in industry。 From the various routes of synthetic vanillin, the process of synthesizing vanillin from guaiacol as raw material is mainly analyzed。

According to the principle of conservation of quality, the quantitative relationship between raw materials and products is calculated according to the principle of conservation of quantity, and the amount of raw materials and auxiliary materials needed for producing finished products is determined。 Accounting, can also calculate a variety of intermediate products, by-products, finished product output and waste emissions, as well as the production process at all stages of raw materials and auxiliary materials loss and its composition。 In the material balance on the basis of further equipment and equipment to calculate the equipment selection。 Material balance and equipment calculations can be done after the end of heat balance。 The heat balance is based on the law of conservation of energy, that is, the energy of the input device is equal to the energy output after operation。

In the production process, material accounting and equipment modeling and the main size to determine the completion of the workshop after the plant can start the layout of the design work。 The main task of the layout of the plant is to arrange the facilities, such as the flat structure of the plant, the internal composition, the production equipment, the electrical setting of the instrument, and so on。 It is designed to meet the requirements of the production process and is economical and practical。 Plant layout is reasonable or not significant, it will directly affect the investment in construction projects, put into operation after operation, maintenance and safety, as well as the completion of the economic indicators。 Therefore, the requirements of the technical staff to master the overall situation, overall consideration, and other relevant personnel to do a good job shop layout design。
