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…
Introduction to separationFluid Separations
Variables that control fluid separation :
• Fluid Pressure• Fluid Composition• Fluid Temperature
Low-Temperature separation
Flash separation Differential Separation
