Stacked Design

The stacked design for multiple effect evaporator systems was first incorporated in 1977. The objective of the stacked design is to simplify the system, minimize vapor ducting, and, in some instances, eliminate transfer pumps and controls. Some of the realized benefits are:

• Reduces civil works and foundation costs.
• Reduces building size and costs.
• Reduces the number of vessel heads and control loops.
• Reduces cost of piping, ducting and supports.
• Minimizes pressure drops.
• Allows space for future modifications and expansions.
