Demineralized water plant in oil refinery

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.
