Demineralized water plant in oil refinery
Industry
Application
Water treatment plant for process water production
Task
To design, manufacture, supervision of the erection and commissioning of the new water treatment plant
Water source
Surface (river) water
About the project
The water treatment unit is designed to produce demineralized and softened water for technological needs. After evaluation of operating cost and water quality requirements, the decision was made to implement membrane technologies for this project.
Technologies
Self-cleaning filters -> Ultrafiltration -> Ion Exchange filters -> Reverse Osmosis
Water treatment plant capacity
268 m3 /h demineralized water
200 m3 /h softened water
Water parameters
| Parameter | Feed Water | DEMINERALIZED WATER |
| рН | <7,7 | 5,0 – 6,0 |
| Chlorides, mg/l | <94 | <5,0 |
| Total Hardness, meq/l | <5,48 | <0,03 |
| Oil products, mg/l | 0,536 | <0,01 |
Summarize
The turbidity, suspended solids, iron, and organic compounds were decreased during the water treatment process. The water treatment process was optimized, and the consumption of chemical reagents was reduced.
