Study Notes
Process Technology
- Energizes liquids to moderately high pressure using a centrifugal pump.
- Energizes liquids to very high pressures using a reciprocating pump.
- Enhances pressure of gases to high values using a compressor.
Storage
- Used to store fluids and gases in storage tanks, especially for liquid fuels.
- Used to store gaseous fuels in pressurized spheres.
Engineering Flow Sheet (PFD and P&ID)
- PFD: Process Flow Diagrams show pipes with flanges, heat exchangers with supports, and each item has a code number (e.g., E for exchangers, C for columns, V for vessels).
- P&ID: Piping and Instrument Diagrams include pipe sizes, valve sizes, pipe fittings, and other mechanical details necessary for engineers.
- Coding for pipes includes nominal pipe size, material code, and sequence number (e.g., 2-Cl-6a' for a 2-inch diameter pipe carrying chlorine).
Conceptual Process Flow-Sheet
- An abstract representation of the actual process flow-sheet.
- Attributes include raw-material purification, processing, transformation, product purification, processing, and recycle of un-reacted raw materials.
Mastering Chemical Process Technology
- Five crucial steps: raw-materials and reactions, conceptual process flow-sheet, process intensification, additional critical issues, and alternate technologies.
Prominent Unit-Operations and Unit-Processes in Chemical Industry
- Various unit operations and unit processes in the chemical industry, including their functional roles.
This quiz covers the types of pumps and compressors used in chemical process industries, including their functions and applications. It is based on the EGCH3120 course notes.
