Qingdao Center production internships report
Summer coming to an end in 2012, ushered in 09 safety engineering production internship——to Qingdao Research Center internship.Mainly as follows:
1.Understand the general flow of the chemical unit;
2.Learn refinery production.Furthermore is the first time in a profeional perspective, look at these large towers, tanks and numerous pipelines.I think that the internship can be summarized in a few words.First, Magnificent, fine
When we have not yet entered the Qingdao Research Center, has been the degree of complexity of the refineries around the pipelines marvel, the complexity of the many pipelines leading to all directions.When we enter the refinery internal see more large and small, rough thin pipeline, in addition to the reactor tank and so on a series of large-scale facilities, introduced in later exposed to variety of valves, pumps, sensors, etc.fine parts.We cannot help but ask: such a large-scale oil refining proce seems simple enough, but how to achieve a single proce, large to large reaction the small every nut screws, is designed, and how reasonable arranged in the area of the factory, and then connected to each before and after the proce, which is how the vast design engineering is exactly right to build it in.The realization of these procees must condense the numerous blood and sweat of Chemical Engineering and Technology profeional technical staff.Second, The physical change and chemical change
I have no contact with the real exposure to the petroleum refining proce, and believe that the refining petroleum engineering is mainly a chemical change.However, when the real enters the refinery and acce to profeional theoretical knowledge known when the petroleum refining, especially in its early proceing is basically a physical change.The oil has just entered the refinery electric desalting dehydration, and atmospheric and vacuum distillation and refining proce, including follow-up deep proceing proce all the physical changes.Regardle of the operational aspects of physical changes of the main procees occupies a very important position in the details of the proce design also reflects the irreplaceable position of the physical changes, including the design and selection of the pump, the flow of fluid within the tube impact factors.The refinery cognition practice in this theoretical study gives us a general direction: the physical changes in the petroleum refining proce is quite important, not because the word “chemical” in the name of our profeional despised application of the physical changes in the petroleum refining.Third, The theory, experience
In this practice, so I was impreed by some of the details-a variety of parameters.Theory in the learning proce, the teacher reminded us in contact with a wide variety of data enters the refinery during the internship to be a lot of records, these data some is derived through theoretical, while the majority of data accumulated over a long period of experimentation and production practices down empirical data
Empirical data in the petroleum refining and design are very rare, is poible that these data will help us to design a set of both output qualified products, but also cost-saving device Conversely,the absence of empirical data, may be because minor problem and a lo, for example, the thickne of the pipe determines the flow rate and the flow rate of the liquid or gas in the pipeline, while the design more thick pipe to ensure that the liquid or gas can be conveyed to the highest efficiency, and safety.The use of these empirical data can not only improve the quality and efficiency of production, but also to ensure maximum production safety, so in the future study and practice, we will intentionally collect these empirical data.Fourth, The risk, safety
Our internships have autumn, but also remnants of a large part of the power of summer, during the day, especially when at noon, the temperature of the factory or high, wearing a helmet, wearing a long-sleeved overalls and pants a not very good about things, and sometimes have to bring gas masks, but the instructors are repeatedly reminded us: Do not take off the helmet in the plant, do not roll up our sleeves, we see that the workers in the factory in the noon heat master indeed a person to find out the helmet, and the master workers not like we are at the foot of what kind of shoes have shoes are unified anti-static anti pinning.Production safety is a top priority, people oriented harmonious society, it becomes particularly important to protect their own safety and the safety of others in the production of each refinery Factory are divided into different fire rating, there will be different levels of production and safety measures in the areas of different levels.All electricity facilities of the plant in the region after the explosion-proof handle, non-hazardous items such as mobile phones is also prohibited from being brought into the production site.Fifth, Traditional, advanced
Different production workshop equipment, their age is not the same.Some equipment since the beginning of construction is still in use, and some equipment is only in recent years equipment production.Refining's one hundred twenty-three factories, the age of most of the major production equipment than our age, refining the production proce from the establishment has basically no big change, new theory proposed, but driven by traditional industries scientific research and development is difficult to go beyond the existing proce.But in some production details are able to reach the innovation in order to improve efficiency and reduce risk.The new lightweight storage and transportation of a plant oil filling oil and gas recovery systems, for example, during the preparations for the Olympic Games in Beijing launched the new device, an effective solution to environmental pollution brought about due to the volatile light oil filling and production of hazardous and other iues;system of real-time oil reconcile the Chinese Academy of Sciences, storage and transportation three plants is a wonderful combination of traditional industrial and information technology in the information age.Sixth, Regret, hope
China's oil refining industry occupies a high position in the world, but the technology still can not reach independent innovation, some parts have to rely on imports.Such as electric valves, domestic companies do a lot of electric valves, but are not required in the refinery Explosion levels, Qingdao Research Center, most of explosion-proof electric valve had to rely on imports, as well as vacuum pumps, centrifugal pumps, fittings, and even special models also have to rely on imports of steel.Our industry in recent years has made great strides, but still a long way to go on the road leading to the technology-intensive, as the next generation of our miion, tomorrow is our.Recognize internship, I have a lot of thoughts and feelings, she does not have to enumerate the refinery relative to the real into refinery production, I am also the equivalent of a blank sheet of paper, I think this time internship really contingent we understand that we have to learn there are a lot of our college life has been three-quarters, but the profeional learning has only just started to reach the final standard, we still have a long way to the internship as an opportunity to refuel, refueling!
