Fluid handling in plants

Pumps, compressors and piping design for process fluids.

In depth

Pipes, valves, pumps, compressors and instruments move fluids safely; design includes line sizing for pressure drop and velocity, pump selection (NPSH), control valves, relief valves and materials. Slurry and non-Newtonian flow need special treatment.

Key points

  • Economic pipe diameter
  • Two-phase flow
  • Valve Cv
Example

A process pump with a control valve downstream regulates flow in a plant.

Why it matters

Plant fluid handling involves pumps, compressors and piping, which must deliver the right flows and pressures safely and reliably.

Where this is used

  • Selecting a pump for a corrosive process liquid.
  • Sizing a compressor for a gas recycle loop.
  • Designing the piping of a plant to avoid cavitation and vibration.

Frequently asked questions

What is Fluid handling in plants?

Pumps, compressors and piping design for process fluids.

Why is it important to understand fluid handling in plants?

Plant fluid handling involves pumps, compressors and piping, which must deliver the right flows and pressures safely and reliably.

What affects pump selection for process fluids?

Flow, head, fluid viscosity, temperature, corrosiveness and whether the liquid contains solids or gas.

Why do process pipes need supports and expansion allowance?

Hot process lines expand, and without supports or loops they can overstress nozzles and equipment.

How is Fluid handling in plants used in practice?

Typical applications include selecting a pump for a corrosive process liquid, sizing a compressor for a gas recycle loop and designing the piping of a plant to avoid cavitation and vibration.

What should I learn before Fluid handling in plants?

Study "Mass transfer" first (topic 88 of 100 in Materials & Chemical). It covers the groundwork this topic builds on.

What are the key points of Fluid handling in plants?

Economic pipe diameter. Two-phase flow. Valve Cv.

Can you give an example of Fluid handling in plants?

A process pump with a control valve downstream regulates flow in a plant.

What comes after Fluid handling in plants?

The next topic is "Process control in chemical plants", which builds directly on this one.

How difficult is Fluid handling in plants?

It is classed as Advanced in Materials & Chemical (topic 89 of 100). It is an advanced topic. It assumes you are comfortable with the intermediate topics in Materials & Chemical.
