On synthetic ammonia and urea
Thread Content
I majored in Applied Chemical Engineering and will be graduating this year; I’m going to work at a fertilizer factory. I know that this factory uses coal to produce fertilizers. Could anyone advise me on what I should learn right now?
Due to limited time, it is recommended that the original poster focus on understanding the following: 1. The process principles and flowcharts of ammonia synthesis and urea production plants. 2. Production capacity of ammonia and urea plants, and consumption of various main raw materials. 3. Schematic diagram of the main equipment structure. 4. Status of the automatic control systems in ammonia synthesis and urea production plants.
Thank you :) :) :)
The chemical engineering technology major should have a course on \"Inorganic Chemical Engineering Processes\", right? Study the textbooks carefully to understand the current situation of urea (fertilizer) production both domestically and internationally, as well as the main technologies and principles involved. Then, after going to the chemical plant, compare it with what you have learned to see which technologies are being used. Advanced features, energy consumption, process flow, etc.!
To understand fertilizer plants, one needs to look at the processes involved from the beginning; there are many steps: 1. Gasification of coal – although fertilizer plants mostly use intermittent processes that are relatively simple. 2. Purification of raw coal gas, including removal of sulfur and toxins such as arsenic and mercury. 3. Shift reaction, with differences between medium-shift and low-shift processes. 4. Carbon removal, using methods such as carbon adsorption, NHD, low-temperature methanol washing, and pressure swing adsorption. 5. Methanol production and methanation, which serve as further purification steps. 6. Ammonia synthesis. 7. Urea synthesis and granulation
Strive to get a position in synthesis; avoid positions related to gasification or urea production – they are not suitable places for people to work.
To work in a fertilizer plant, you need to learn things gradually, starting from scratch. First, you need to understand how to convert blackberry into white urea. Once you know the manufacturing process and the purpose of the equipment, you can then gradually learn about the process parameters and operational standards, and over time you will come to understand much more
