✦ Synopsis
An updated desalted water cost comparison Will be presented for the Reverse Osmosis, Multistage Flash Evaporator and the high efficiency performance
Vapor Compression Vertical Tube Foaming Flow Evaporator (VTFE). The capital cost of the VCVTFE plant is based on a realistic conceptual design for a 2.5 mgd Single Purpose plant.
There are several interesting desalting design concepts that will be presented which can only be realized through the use of the low AT vertical tube foaming flow evaporator. Together with the vapor compression cycle, high performance ratios of about 35 lbs.
product per 1000 Btus can be readily achieved. These high efficiency concepts and use of waste heat are economical with current day high fuel costs.
L'exposg presente une comparafson du co8t de l'eau dessalee pour les syst&ues: osmose inverse, Bvaporateur instantan B multiples &ages et 6vaporateur B compression de vapeur, tube vertical et flux moussant (VTFE). 11 traite &galement les conceptions de diffkentes options de distillateurs utilisant la chaleur perdue d'une turbine B gaz. Les frais de ces conceptions a basse consommetlon en 6nergie sont cornpar& ri ceux des systSmes conventionnels d'Bvaporation instantanee a Stages multiples et d'osmose inverse. La vapeur sortant de la turbine (chaleur perdue) peut gtre mise 2 profit pour produire de l'eau dfstillge. Un tableau presente le coat d'investissement de l'installation et le coat de l'eau par rapport 1 plusieurs valeurs de cogt de l'krergie.
