Deck 9: Process Technology-Systems Two

Question 1

Sketch a simple flare system.

Answer 1

A simple flare system typically consists of a vertical stack or tower with a burner at the top. The burner is connected to a fuel source, such as natural gas or a liquid fuel, and is designed to safely burn off excess or unwanted gases. The stack is equipped with a flame arrestor to prevent flashback and is often fitted with a pilot light to ensure continuous ignition.

The flare system may also include a knockout drum or separator to remove any liquids or solids from the gas stream before it reaches the burner. Additionally, a control system is used to monitor and regulate the flow of gas to the flare, ensuring that it operates safely and efficiently.

Overall, the purpose of a flare system is to safely combust and dispose of waste gases that cannot be processed or captured for reuse. It is an important safety feature in many industrial facilities, particularly those that handle hydrocarbons or other volatile materials.

Question 2

The function and operation of an extruder is most closely described as:
