3.12 Implement of ideological and political education
By combining the knowledge point of the textbook, the technological progress of pressure vessels and process equipment in China in the past 40 years since the reform and opening-up will be introduced in the teaching process. For example, in Chapter 1, it will be introduced that with the rapid development of China's economy and society and the requirements of environmental protection, the unremitting efforts of several generations of scientific and technological personnel, our country has developed from imperfect specifications to the current complete pressure vessel quality assurance system in the design, manufacture and use of pressure vessels. In Chapter 3, it will be introduced that scientific researchers in our country’s materials industry have developed superior performance pressure vessel steels and performance enhancement technologies, for the sake of improving the international competitiveness of our country’s pressure vessel products. In Chapter 4, it will be introduced that our country is constantly innovating independently while learning advanced technologies from developed countries in the world. It adopts advanced design concepts to solve the design and manufacturing problems of many high-parameter key pressure vessels (such as hydrogenation reactors) in China, and significantly improves the pressure vessels in our country. The level of technology has won honors for the country and created huge economic and social benefits. The introduction of these contents enables students to understand their professional progress, and at the same time cultivate their home country feelings and their sense of responsibility towards the country and society.
The design and manufacturing progress of key process equipment in our country will be also introduced. For example, in Chapter 5 of container equipment, the 150km3 capacity of above-ground floating-roof crude oil container and the 200km3 LNG container built for the establishment of a strategic petroleum reserve base will be introduced. In Chapter 6 of heat exchanger, it will be introduced the the large-scale plate and shell heat exchanger which reflecting the world’s advanced manufacturing level has a heat exchange area of 8000m2. In Chapter 7 of column equipment, the atmospheric column with a diameter of 10m and the vacuum column with a diameter of 16m will be introduced to illustrate the tremendous development of our country’s oil refining industry. At present, the refining capacity of a single atmospheric and vacuum distillation unit in our country has reached 12 million tons/year, which stands in the forefront of the world. In Chapter 8 of the reaction equipment, the construction technology of hydrogenation reactors will be introduced. From the import of all hydrogenation reactors in the 1980s to the large number of exports now, it indicates that our country’s petrochemical equipment manufacturing industry has reached the world’s leading level. These typical cases illustrate the fruitful achievements of our country’s petrochemical equipment manufacturing industry since the foundation of the People’s Republic of China 70 years ago, especially since the 40 years of reform and opening-up. It is the result of the hard work of several generations of scientific and technological workers in our country, and also reflects the superiority of our country’s socialist system. It embodies the determination of the Chinese Communist Party to lead the people of the country to work hard to realize the great Chinese dream of rejuvenating the heart and will.
