Demineralized Water Systems
Demineralized water packages that produce the high-purity water gas turbine and steam cycle plants require, from raw or municipal feed to storage and forwarding.
Role in the plant
Gas turbine plants use demineralized water for applications such as water injection, power augmentation and compressor washing, and steam cycles use it as boiler and HRSG makeup. Each use carries a purity limit, and the package is built to meet it at the flow the plant needs.
- Purity limits taken from the OEM and the project specification
- Storage and forwarding sized to peak demand
- Analyzers, alarms and controls function-tested before shipment
Typical package scope
| Element | Function |
|---|---|
| Pretreatment | Filtration and conditioning of the feed ahead of the membranes |
| Reverse osmosis | Removes the bulk of dissolved solids |
| Polishing | Electrodeionization or mixed-bed ion exchange to the purity specified |
| Storage and forwarding | Storage interface and forwarding pumps |
| Instrumentation | Conductivity, flow, pressure and level instruments with alarms |
| Controls | PLC control with plant communications |
Design basis
Each package is engineered to the project requirements, specifications, governing codes and OEM requirements that apply, for a single installation or a standardized fleet.
| Design input | What it determines |
|---|---|
| Feed water | Source and full water analysis |
| Purity | Conductivity and silica limits for each use |
| Demand | Continuous and peak flow, including injection or wash cycles |
| Storage | Buffer volume and forwarding pressure |
| Redundancy | Duty and standby trains as uptime requires |
| Site | Footprint, enclosure, ambient range and area classification |
