Introduction to separationEmulsions, Hydrates & Paraffins

Emulsions: At least one substance is finely dispersed throughout another.

Paraffins: sticky, plastic substance that may form plugs in equipment.

• Heating fluids to melt the paraffin. • Injecting chemical solvents.• Mechanically scraping it from surfaces

Hydrates: Solid formed when mixtures of water vapor and high-pressure gas are cooled.

Unless a source of heat is provided or inhibitors are administrated, temperature must be held above the temperature at which hydrates form

• Liquid desiccants: Glycol• Solid desiccants: Silica Gel, Sovabeds…
