Process Design of a 100,000 Gallon per Day Vacuum Freezing Ejector Absorption Pilot Plant

摘要

A conceptual design study of the vacuum freezing ejector absorption (VFEA) process was completed and specifications were prepared for a nominal 100,000 gallon per day pilot plant. Included in the design are a process flow sheet, piping and instrumentation diagrams, equipment specifications, a computer program model, and preliminary engineering drawings. VFEA is a freeze desalination process in which water vapor from a vacuum freezer is compressed by a combination steam ejector and absorber loop. The absorption solution for this design is concentrated sodium hydroxide. Also included is an estimated budget cost to do the final engineering and to build the pilot plant.
