This document provides an overview of main equipment in a desalination plant, including evaporators, brine heaters, and deaerators. It discusses the manufacturing process and transportation of evaporators specifically. The key points are: 1) It describes the main equipment in a desalination plant and their purposes, focusing on evaporators, brine heaters, and deaerators. 2) It explains the manufacturing process for evaporators, including bundle assembly, testing, and the advantages of one-module manufacturing. 3) It outlines the transportation process for large evaporator modules by ship, including loading, securing, and routing to the installation site.

15. One-Module Manufacturing
Method
Block Manufacturing
Method
One-Module Manufacturing Method is to ship Eva. with complete
assembling condition after manufacturing and assembling each bundle in
the shop.
Keep quality of the Evaporator and prevent problems from taking to the
pieces and assembling in the site.
Reduce construction time over 5 months and decrease amount of work in
the site
Divide the Evaporator into 2~4 blocks after manufacturing each bundle in
the shop.
Amount of work increases unless we use one-module manufacturing
method in the site
Make use of overseas manufacturing companies in the site
