Complex catalytic device

Don't be anxious, accumulate it bit by bit, read more books, and ask more teachers for advice.

From the industrialization of the catalytic cracking process until 1960, most of its raw materials were vacuum distillates and secondary processed distillates. Only in 1961, Phillips used Kellogg's patent to build the world's first true heavy oil catalytic cracking unit (HOC) at the Borger refinery. Since the 1970s, as the energy crisis has changed the structure of demand for petroleum refining products, the demand for heavy oil, or residual oil, has steadily declined, while the demand for light distillates such as gasoline and diesel has increased. One solution to the above changes in demand for petroleum products is to convert more heavy oils or residues into light distillates. Therefore, heavy oil catalytic cracking has developed rapidly. In addition to HOC developed by Kellogg Company in the 1960s, starting in the late 1970s, Ashland Company cooperated with UOP Company to develop residual catalytic cracking technology (RCC). ； Total (U.S.) Petroleum Company also developed residual catalytic cracking (RFCC), but sold its patent rights to Stone and Webster. ； Shell Company has also independently developed its residual catalytic cracking technology. Therefore, there are only four types of real residual catalytic cracking abroad today.: That is, HOC, RCC, SWEC's RFCC and Shell's residual catalytic cracking. In the 1980s, in order to accelerate the progress of my country's heavy oil processing, promote the technological progress of my country's heavy oil catalytic cracking, and improve the economic benefits of the company, Sinopec Corporation introduced five sets of residual catalytic cracking technology (RFCC) from the American Stone and Webster Company. Among them, Wuhan Petrochemical Corporation and Zhenhai Refining and Chemical Company were used in the renovation of old devices, while Guangzhou Petrochemical, Changling Refinery and our plant were newly constructed devices. After digesting, absorbing and improving this technology, it has played a certain role in the development of my country's residual catalytic cracking technology.

The catalysis process is very complex. It is impossible to learn it all at once. We have studied for three years and have become class presidents, but we still feel that we have not studied well. hehe. Be specific: reaction: Among the three major balances, the most critical one is pressure. The pressure of the three devices (some devices have two devices) must be guaranteed to be within the target range. If the pressure is unstable, the reaction will not be stable. Then, you must pay attention to the temperature, storage volume, air volume, etc. Generally speaking, reaction is the most difficult to learn. You must be bold, careful, and calm. Our director once said: Cultivating a qualified reaction master is no less important than cultivating a general. It usually takes two or three years to study. Fractionation: Relatively simple, temperature is key. Just keep a steady eye on the liquid level everywhere, adjust it in small steps, and the quality is generally guaranteed. The main thing is to strengthen job contacts. It usually takes one or two years to study. Stable and refined: If you get a good name, it will appear relatively stable at first glance. As long as the pressure and fluid level are taken into account, there is generally no problem. You just need to pay attention when driving and parking. Usually one year. I have never worked on the third unit, so it’s hard to say. Judging from the salary, it’s probably about half a year. advice: 1. Pretend to understand something you don’t understand. 2. Do things you are not sure about. 3. Memorize on-site procedures, operating procedures, and accident plans. 4. Be confident and don’t panic when encountering problems. 5. Experience is more important than anything else.

advice: 1. Don’t pretend to understand something you don’t understand. 2. Don’t do things you’re not sure about. 3. The installation site procedures, operating procedures, and accident plans must be memorized. 4. When facing emergencies, be confident and don’t panic. 5. Sometimes experience is more important than anything else. What the 4th floor said is very good, I feel the same way, :lol I borrow flowers to offer to Buddha, haha.

The main reason is that air and oil and gas may cross each other. The reaction is a catalyst reaction and there is a fluidized medium, which is relatively complicated.

I partially agree with the 4th floor's point of view. It takes 3 years to develop into a qualified reaction operator, but it takes another 5-7 years to become an excellent reaction operator.

The reaction is mainly based on theoretical knowledge + calmness and confidence. Fractionation and stabilization are the main contents. The external process is the main content. After working in the factory for more than a year, the deepest impression is the two unplanned shutdowns. I learned a lot from the start and shutdown.
