Abstract:
1. A method for reducing scaling in a distillation system comprising: supplying fluid to the distillation system through an inlet fluid feed line; preconditioning the fluid in said fluid feed line by passing the fluid through at least one filter in-line with said fluid feed line; connecting an outlet of said fluid feed line to a double container boiler vessel having an outer container and an inner container and having a preheater region between said outer and inner containers, said outer container and said inner container being in fluid connection, and said outer container including a drain port; supplying fluid from the fluid feed line to said boiler vessel to at least partially fill said preheater region and said inner container; heating the fluid in said preheater region and said inner container so that a portion of the fluid in the preheater region and a portion of the fluid in the inner container each change phase to respective fluid vapors; venting the fluid vapor in said preheater region through a plurality of vents in said outer container; collecting the fluid vapor in said inner container; and transporting said inner container fluid vapor from inner container to a condenser.
