First Review for chemical engineering students
- 1. Contents: Objectivesof the project Flow sheet of the process Raw materials Reactor Process Air Preheater Process Oil Preheater Bag Filter Surge Bin & Powder Pump Pelletizer Dryer Storage & Loading Problems during Process Key Learnings
- 2. The objectivesof the project are :- To develop skills in the application of theory to practical work situations. Gain the Knowledge about DCS. Design of Air Pre Heater. Design that the heat is generated will reuse that we seen in process. Key Learnings: We learns that how operations are done and which safety the workers are taking while working at around the 2000°C. Learn about zero liquid discharge. Learn about different Heat exchanger. The benefits of taking on feedback. Future work Mass balance Energy balance Design of Heat Exchanger

- 27. There aretwo problems: 1. They have big problem of the sodium chloride salts which is generated from there zero liquid discharge departments. 2. oil which is spraying in the reactor they have to set every time due to that they to face a cost to change the inner part of the which is refractory bricks.
- 28. Key Learnings: We learns that how operations are done and which safety the workers are taking while working at around the 2000°C. Understanding workplace culture. How important good communication is. The benefits of taking on feedback. Future work Mass balance Energy balance Design of Heat Exchanger
