Demineralization plant components

The basic components of the plant and the demineralization process (Figure 3-18) are described in the following paragraphs. 

Utilities are generally the first to be commissioned in order to provide facilities such as electric power, cooling water, demineralized water, instrument air, plant air and inert gas. Individual plant systems and equipment items are then checked for completeness against line diagrams, component drawings and schedules while lists are prepared of outstanding items (see Chapter 7).
